Abstract:

Although the use of monetary incentives as motivational tools has been studied by previous researchers, the mechanism of the relationship between monetary incentives and behavior/performance remains poorly understood. The purpose of this quasi-experimental investigation was to explore the relationship between 3 levels of monetary incentives ($0, $3, and $10) and the athletic performance of adolescent male soccer players. The moderating effect of perceived physical self-efficacy or intrinsic motivation on the relationship between athletic performance and monetary incentives was also investigated. The framework for the study was comprised of expectancy theory, the theory of planned behavior, and self-determination theory. Study participants included a convenience sample of 16 adolescent male soccer players between the ages of 11 and 13 who played on a youth soccer league in the Midwestern United States. The independent variable was level of monetary incentive, and the dependent variable was athletic performance (time on the 50-yard dash). Intrinsic motivation was assessed using the Sport Motivation Scale. Perceived physical self-efficacy was assessed via participants' scores on the Physical Self-Efficacy Scale for Children. Analysis, which included a repeated measures linear mixed-effects model and post-hoc pairwise comparisons, revealed that players' athletic performance increased as monetary incentives increased. Intrinsic motivation and perceived physical self-efficacy had no statistically significant interaction effect on the relationship between athletic performance and monetary incentives. Findings shed light on the potential usefulness of monetary incentives among male adolescents, and may be used by coaches to foster a mindset of achievement and goal-orientation.

Abstract:

Les actions sociales par le sport ont fait l'objet de nombreuses etudes dans le champ des sciences sociales. Beaucoup de travaux mettent en avant les effets de ces actions sur les populations marginalisees et plus particulierement sur les adolescents des quartiers dits "sensibles". En outre, le sport apparait dans le discours scientifique comme un vehicule ideologique et de controle, mais aussi, comme un vecteur d'education et de bien-etre. Ainsi, le paradoxe s'affiche lorsque des actions sont mises en place dans une optique socialisante et avec le sport comme outil paradoxal. De ce point de vue, l'hypothese d'un mythe autour des effets de l'activite sur le comportement pourrait etre posee, et les discours pourraient etre reconnus comme mythiques, car empreints d'une double croyance dans le sport. C'est donc a partir de l'idee selon laquelle les propos des acteurs sociaux produisent du mythe, et se structurent sur le modele antique, que ce travail s'est construit. L'interet a alors ete porte sur l'etude des discours, car, si le mythe existe, c'est par la parole qu'il se devoilera.

Abstract:

The purpose of this research was to conduct an exploratory study of parental involvement in youth sports. The Flow Model developed by Mihalyi Csikszentmihalyi is used as the basis of my theory behind the research. Although there has been recognition that it is important to study young athletes, little is known about parental involvement. Thus, my three main research questions are: (a) How do adolescents experience their participation in soccer? (b) What are the family dynamics, as expressed by parents, related to challenging and supporting their children? And (c) How do adolescents experience the relationship between these family dynamics and their participation in soccer? My methods of inquiry of this study included collecting data through two questionnaires: (a) Experience Sampling Method (ESM) and (b) Support/Challenge Questionnaire (SCQ). I also conducted in-depth interviews. My participants included 11 males and 10 females 14-15 years of age. Each of these participants were administered the two questionnaires. Of these 21 participants, eight adolescent athletes and their parents were followed up with in-depth interviews. The results of this research are organized into four main categories including communication, family interaction, goals and beliefs, and expectations. From these themes, three categories for implications were developed to encompass soccer implications, therapy implications, and research implications. Ultimately, acknowledging how adults affect the outcomes of children's stress and enjoyment, parents can deal more successfully with the social, emotional, and psychological needs of their young athletes (Scanlan & Lewthwaite, 1986).

Abstract:

Background: Swimming is a popular competitive and recreational sport performed worldwide by all generations. Although swimming is associated with many positive health benefits, swimmers are at risk of developing musculoskeletal injuries. In particular, competitive swimmers may be at increased risk of injury, due to regular participation in demanding training regimes. Adolescent swimmers may be at increased risk of injury due to physiological and biological vulnerability associated with growth and development. However, there is a lack of evidence regarding the epidemiology of injuries in competitive adolescent swimmers. Aim: The aim of this study was to determine the relationship between injury incidence and potential risk factors in adolescent swimmers over a 24 - week period. Specific Objectives: (a) To describe the demographic and training characteristics of competitive adolescent swimmers; (b) to establish the incidence and nature of self - reported swimming - related injuries in competitive adolescent swimmers; (c) to determine if any specific intrinsic factors and extrinsic factors were associated with increased risk of injury in competitive adolescent swimmers. Methods: Twenty three competitive adolescent swimmers aged 12 to 18 years were recruited for the study. Swimmers attended a study information session and parents/legal guardians were emailed information sheets and informed consent forms. All participants brought signed informed consent forms from parents/legal guardians to the baseline data collection session. At baseline testing participants signed their own informed assent forms and completed the baseline questionnaire, anthropometry measurements, glenohumeral range of movement measurements, the Beighton score and glenohumeral and knee muscle strength measurements. Participants were advised on how to complete the electronic injury report and training questionnaire. A familiarisation trial - run of the survey was completed in the week following baseline testing. Formal data collection commenced two weeks after baseline testing. Participants were required to submit the injury report and training questionnaire on a weekly basis for the 24 - week study period. Results: The mean age for commencement of swimming training in both the injured and uninjured groups was approximately 7.5 years. The injured group had significantly decreased subscapularis muscle strength (p = 0.02) and significantly higher average training session distances (p = 0.04), compared to the uninjured group. Fourteen participants (60%) sustained injuries during the 24 - week study period. The injury rate was 22.4 per 1 000 athletic exposures (AE's). Sixty injuries were sustained in total; 16 were index, and 44 were recurrent injuries. The most common injury location was the knee joint (n = 20). The only factors associated with increased injury risk in this study were previous injury history (OR: 7.50; 95% CIs 1.02 - 55.00) and reduced percentage of time in breaststroke training (OR: 12.83; 95% C I s: 1.69 - 97.19). Few swimming training sessions were modified or changed due to injury, and the majority of injurie s did not receive any treatment. Conclusion The injury incidence of adolescent competitive swimmers attending a Johannesburg - based swim squad is high. In addition, the high number of recurrent injuries, the minimal adaptation of training loads in response to injury, and the low access to appropriate treatment suggest a lack of knowledge or poor practices regarding swimming - related injuries. Pre - season screening, specific to swimming, could assist in identifying weakness and potential risk factors for injury in this vulnerable age - group. Improving health literacy with education in swimmers, coaches and parents could reduce future injury incidence rates. Therefore, further research is needed regarding injury incidence, risk factors and training profiles of this population. Moreover, consensus regarding injury definitions and training loads in adolescent swimmers is needed to standardise reporting and to facilitate further research in this field.

Abstract:

This paper explores the empowerment of adolescent girls through sport using two case studies. Both case studies take place in predominantly Muslim countries: Egypt and Bangladesh. The sports programs also are both implemented through schools, public in Egypt and private in Bangladesh. I also evaluate the feasibility of establishing sports programs across the world. Because of Afghanistan’s especially harsh circumstances for women, the final chapter strategizes methods to implement similar programs there. I conclude by assessing the future of girls' sports programs in the Middle East and whether or not governments and international organizations should continue investing in these programs.

Abstract:

This multi-method study explored the link between sports involvement during the high school years and sexual behavior/health among 176 adolescent women. The current study employed quantitative methodology to replicate the documented connections between sports involvement and adolescent women's sexual behavior and sexual/reproductive health, but used more sensitive and appropriate measures. Additionally, in part directed by cultural resource theory, the present study helped to fill a gap in the literature by exploring three potential explanatory mechanisms (i.e., mediators) in the above connections. Those mechanisms included: (a) functional body orientation; (b) self-empowerment/efficacy; and (c) sexual/reproductive health-related information/motivation via coach. Results from the quantitative data suggested that adolescent women's involvement in organized team sports was favorably associated with each of the following: (a) sexual risk-taking behavior, (b) sexual/reproductive health-seeking behavior, and (c) sexual/reproductive health. In addition, both adolescent women's functional body orientation and adolescent women's self-empowerment/efficacy emerged as mediators in the associations between adolescent women's sports involvement and adolescent women's sexual behavior/health. Thus, the current study suggests the potential for sports involvement to favorably influence adolescent women's sexual behavior/health and pinpoints key mechanisms that help to clarify the nature of that influence. The current study used qualitative methodology to explore the ways in which the adolescent women felt that their sports involvement influenced their lives and feelings about their bodies. In general, the sports involvement-derived outcomes that emerged from the adolescent women's written comments were positive, suggesting that the adolescent women felt that their sports involvement during their high school years was overwhelmingly beneficial. Potential implications of those outcomes for the sexual/reproductive health of adolescent women are discussed. Qualitative methodology also was used in the current study to explore adolescent women's experience of sexual/reproductive health-related coach talk. Based on the adolescent women's reports of their experiences of such coach talk, it appears that coaches might be one logical and effective avenue by which key sexual/reproductive health messages can be transmitted to adolescent female athletes. Implications for the development of sports and community programs focused on the prevention of teenage pregnancy and STDs are discussed.

ENGLISH ABSTRACT: This study explored the potential of competitive games and cooperative games as means for teaching adolescent girls some of the concepts that support cooperation. Hellison's (1995) levels for teaching responsibility were used as guidelines for selecting specific teaching strategies. The intervention consisted of a theme-oriented intervention programme presented to two experimental groups. One group (n = 9) participated in a games programme that consisted of competitive activities and the other group (n = 9) participated in a games programme that consisted of cooperative activities. The experimental groups were presented with theme-oriented lessons based on four concepts that support cooperation: sportsmanship, communication, trust and responsibility. A control group (n = 18) was also identified and used for statistical comparisons. In order to set a context for this study, background information was gathered using a questionnaire to determine how girls from the school (N = 194) felt about competitive games and sports. Three measurement instruments were used to collect data. The assessment of how the girls at the school felt about competitive games and sport was completed, using Gill & Deeter's (1988) Sport Orientation Questionnaire (SOQ). Pre- and posttesting of the girls in the experimental groups also included the SOQ. Harter's (1985) Self-perception Profile was used to measure perceptions of perceived social acceptance. Soudan and Everett's (1981) 24-item questionnaire was used to determine any changes in how the girls in the experimental groups perceived the benefits of participation in physical activity. Results of the Sport Orientation Questionnaire for High School Girls (N = 194) indicate that the girls like competitive activities and enjoy competing, but for them, it is more important to set personal goals in competitive games than it is to win. Following the comparison between pre- and post-test data, it was concluded that the theme-oriented competitive games programme had an effect on how the girls feel about participation in games and sports. They became significantly less competitive in their orientation. No changes were noted in their perceived social acceptance. A significant increase in their perception that participation in sport and physical activity has social benefits as well as benefits in preparing them for a career/job were noted. The theme-oriented cooperative games programme also had a significant effect on how the girls feel about participation in games and sports. The competitive nature and win orientation of the girls participating in the cooperative games programme significantly decreased. No changes were noted in their social acceptance. There was a significant increase in their perception that participation in sport and physical activity has health and fitness benefits. Results on comparing the groups indicate that the perceived athletic competence of the competitive group increased significantly when compared to the cooperative group. No other changes were noted. A themeoriented approach to teaching children about cooperation in a competitive and/or cooperative environment seems to be an effective strategy.
AFRIKAANSE OPSOMMING: Hierdie studie het die potensiaal nagevors van kompeterende spele en koëperatiewe spele as maatstaf vir die aanleer van sommige van die konsepte wat samewerking ondersteun. Hellison (1995) se vlakke vir die aanleer van verantwoordelikheid is gebruik as riglyne vir die seleksie van spesifieke onderrigstrateg ieë. Die intervensie het bestaan uit 'n tema-geërienteerde intervensieprogram wat aan twee eksperimentele groepe voorgelê is. Een groep (n = 9) het aan 'n speleprogram deelgeneem wat bestaan het uit kompeterende aktiwiteite en die ander groep (n = 9) het aan 'n speleprogram deelgeneem wat uit koëperatiewe aktiwiteite bestaan. Tema-geërienteerde lesse wat op die volgende vier konsepte wat samewerking ondersteun gebaseer is, is aan die eksperimentele groepe voorgelê: sportmanskap, kommunikasie, vertroue en verantwoordelikheid. 'n Kontrolegroep (n = 18) is ook geïdentifiseer en gebruik vir statistiese vergelyking. Om 'n konteks vir hierdie studie daar te stel is agtergrondinligting met behulp van 'n vraelys ingesamel om vas te stel hoe meisies van die skool (n = 194) gevoel het oor kompeterende spele en sport. Drie meetinstrumente is gebruik om data in te samel. Die assessering oor hoe die meisies gevoel het oor kompeterende spele en sport is voltooi deur van Gill & Deeter se (1988) Sport Orientation Questionnaire (SOQ) gebruik te maak. Pre- en post-toetsing van die meisies in die eksperimentele groepe is ook in die SOQ ingesluit. Harter (1985) se Self-perception Profile is gebruik om die persepsies van waarneembare sosiale aanvaarding te meet. Soudan en Everett (1981) se 24-item vraelys is gebruik om enige veranderinge te bepaaloor hoe die meisies in die eksperimentele groepe die voordele van deelname aan fisieke aktiwiteit ervaar het. Resultate van die Sportoriëntasie-vraelys vir Hoërskoolmeisies (n = 194) het aangedui dat die meisies kompeterende aktiwiteite en kompetisie geniet, maar dat dit vir hulle belangriker is om persoonlike doelwitte te stel in kompeterende spele as wat dit is om te wen. Na afloop van die vergelyking tussen pre- en post-toetsdata, is daar bevind dat die tema-georienteerde kompeterende speleprogram 'n effek gehad het op die meisies se gevoeloor deelname aan spele en sport. Daar was 'n beduidende afname in hul kompeterende oriëntasie. Geen veranderinge is gemerk in hul waarneembare sosiale aanvaarding nie. 'n Beduidende toename is opgemerk in hul persepsie dat deelname aan sport en fisieke aktiwiteit sosiale voordele sowel as voordele vir die voorbereiding van 'n loopbaan/werk inhou. Die tema-georienteerde kooperatiewe speleprogram het ook 'n beduidende effek gehad op hoe die meisies oor deelname aan spele en sport voel. Die kompeterende aard en wenoriëntasie van die meisies wat aan kooperatiewe speleprogram deelgeneem het, het beduidend afgeneem. Geen veranderinge is in hul sosiale aanvaarding opgemerk nie. Daar was 'n beduidende toename in hul persepsie dat deelname aan sport en fisieke aktiwiteit gesondheids- en fiksheidsvoordele inhou. Resultate wat die groepe vergelyk, dui aan dat die waarneembare atletiese vermoë van die kompeterende groep beduidend toegeneem het in vergelyking met die kooperatiewe groep. Geen ander veranderinge is opgemerk nie. 'n Tema-georienteerde benadering tot hoe om kinders oor samewerking in 'n kompeterende en/of kooperatiewe omgewing te leer, blyk 'n effektiewe strategie te wees.

Abstract:

La pratique d’activité physique sportive ‘APS’ est un facteur de santé. Le sport est une forme d’activité physique ‘AP’ qui aide à atteindre les taux recommandés journaliers. Des plans de promotion des APS sont adoptés par les Etats Européens. Mais la pratique sportive recèle aussi des risques. Certaines blessures sportives génèrent des troubles de santé à long terme. La promotion de l’activité sportive est face à un paradoxe. Moyen d’être en bonne santé, elle comporte des risques liés aux modalités de pratique. Pour connaître l’ampleur de ces effets, des études épidémiologiques sont nécessaires. Elles aideront à déterminer les sous-groupes d’adolescents sportifs, et parmi eux, ceux qui sont à risque de blessure. En France, les études menées sont représentatives de la population nationale. En revanche, aucune n’a estimé la participation et les facteurs de risque en se focalisant sur la population adolescente. Aussi, la littérature internationale fait ressortir des variations de résultats en fonction de l’environnement de vie des participants. Nous avons donc réalisé des enquêtes épidémiologiques auprès de la population adolescente d’un département français spécifique : les Bouches-du-Rhône. Celui-ci se caractérise par un haut-niveau de pauvreté et d’inégalité. Par hypothèse, les résultats différent de ceux obtenus à l’échelon national. En plus des mesures objectives de participation et de blessures, nous avons questionné les adolescents sur les expériences qu’ils aimaient vivre dans leur sport préféré. Cette connaissance vise le développement d’initiatives de promotion de l’activité sportive adaptées aux goûts de cette population. (résumé non complet)
Participation in physical and sports activities ‘PSA’ is a health factor. Sport is a form of physical activity ‘PA’ that helps to reach the recommended amount of PA per day. PSA promotions plans are launched by European states. However, sport participation also involves significant risks. Some sports injuries provoke long-term health negative outcomes. Promotion of sport participation faces a paradox. As a mean of healthy state, it implies some risks linked to the modalities of participation. To know the extent of these effects, epidemiological studies are needed. They help to determine adolescents’ subgroups that play sports, and among them, those at greater risk of injury. In France, previous studies are representative of the national population. However, no study estimated sport participation and injury risks factors while focusing on adolescent. Moreover, international findings showed that variation of results exists as function of the life environment of participants. We performed epidemiological retrospectives studies among the adolescent population of a specific French locality: the Bouches-du-Rhône. This one is characterized by a high-level of poverty and inequalities. We made the hypothesis, that results differ compared to those obtained at the national level. In addition of objectives measures of participation and injuries, we asked adolescents about the experiences that they like to live in their favorite sport. This knowledge could be useful to the development of promotion initiatives that are adapted to the tastes of this population. (resume no complete)

Abstract:

The purpose of this study was to explore the stress-eating relation established in the literature by examining a naturally occurring stressor, adolescent dating violence, and its effect on eating in adolescent girls. Specifically, analyses focused on assessing the mediating role of depression in the adolescent dating violence-fruit and vegetable intake relation and the moderating role of sports team involvement in the adolescent dating violence-depression relation. A nationally representative sample of 5,892 black, Hispanic, and white adolescent girls were surveyed using measures assessing physical and sexual dating violence experiences, depressed affect, suicidal thoughts, plans, and/or attempts, fruit and vegetable intake and involvement in team sports. This study supported the hypothesis that depression mediates the relation between adolescent dating violence and dietary intake, but only in black adolescent girls. These findings suggest that black girls victimized by dating violence experience depression, which may affect their desire or motivation to eat properly. This study also supported the hypothesis that sports team involvement, a source of social support and physical activity, moderated the relation between adolescent dating violence and depression and suicidality, but only for white adolescent girls. For this group, participating on a sports team served to protect those girls reporting dating violence from experiencing depression at the high rate reported by those dating violence victims not involved on a sports team. The findings presented in this study provide evidence that depression explains how experiences of dating violence affect eating behavior for a high-risk group, black adolescent girls. Recognizing depression’s contribution to this group’s high rate of obesity and overweight is an important step in preventing obesity and obesity-related outcomes in this population. Also, this study highlights an important source of social support, sports team involvement, and its potential to protect dating violence victims from experiencing depression and suicidal ideation, plans, and attempts.

Abstract:

The purpose of this project was to create a nutrition education program with relevant nutrition topics for parents with at least one adolescent child attending an elite training school for figure skating. This program aims to enhance parental knowledge and increase awareness surrounding the nutrition needs of elite adolescent figure skaters. The 6-week nutrition education program consists of six 40-minute PowerPoint presentations with corresponding topic-specific handouts, activities, and lesson plans. Each lesson includes a research-based curriculum, providing parents with specific nutrition recommendations to promote healthy eating patterns for their adolescent figure skating children.

An expert panel comprised of three registered dietitians with sports nutrition experience reviewed the curriculum using the Formative Evaluation. The average scores from the evaluation were positive, indicating that the curriculum is appropriate, accurate, and provides valuable information for the target audience. To further evaluate the curriculum’s efficacy, a study could be conducted to facilitate this 6-week nutrition curriculum to determine the curriculum's effectiveness by assessing class participants’ nutrition knowledge before and after implementation.

An extensive literature review was conducted to investigate the best ways to incorporate combat sports into a youth development program with the goals of increasing self-esteem, enhancing social relationships with peers and adults, and supporting the development of healthy male identity. The program consists of two components: 1) boxing program and 2) group discussion. As many as 20 adolescent males would be served from three high schools in the city: Cabrillo High School, Jordan High School, and Polytechnic High School.

The program was developed to address the potential impact of growing up in economically disadvantaged and high-risk neighborhoods. Program goals will be achieved with a boxing program that includes post-training discussions. The integration of sports and group discussions will allow for an environment that can both support and empower adolescent males. Long Beach United Boxing Club, the program site, has a strong standing reputation of providing a safe and open environment in which youth can thrive. The Foundation for Global Sports Development was selected as the best potential funder because of its commitment to promoting the well-being of underserved youth.

If funded, this program would be a model upon which other programs could build. Combat sports involvement is an innovative and dynamic way to reach hard-to-engage youth and provide a supportive space in which they can thrive. The thesis project did not require the submission of the proposal.

Abstract:

This thesis aims to identify physiological and biochemical variables, comparing sex, training status, age and maturity in sub-elite, endurance trained adolescents. Maximal lactate steady state was investigated and the effects of endurance training programmes measured.T he first study assessedth e reliability of absolute running speed, V02, and HR that correspond to the fixed blood lactate reference values of 2.0 and 2.5 mmo1. L"1 and the lactate threshold (LT) and found these measures to be reliable after endurance-trained adolescent runners completed two identical incremental treadmill tests within a 7-10 d period The second study was designed to determine the relationship between physiological variables and endurance running performance in this age group. Track-based, running performance times were available for 18 boys and 14 girls for the 800 m, and 16 boys and 13 girls for the 1500 m. The participants were tested using a step-wise incremental treadmill test and a Wingate anaerobic power test (WAnT) on separate occasions. The results from this study found that for the 1500m, running speeds corresponding to the fixed [BLa ] were a useful measure for assessing performance in endurance trained boys and girls. Unlike previous studies, peak V02 was not a significant physiological predictor of 1500m performance in either boys or girls. For the 1500 m performance in girls the anaerobic measure was no longer significant once variations in size or age had been taken into consideration. Whereas V VO2 peak and running economy may prove to be of some value when considering the 800m for boys, the running speed corresponding to a [BLa ] of 2.5 mmol-L-1 was the only meaningful physiological predictor variable for girls once differences in age and body size had been accounted for. The third study had three main objectives: (1) to identify the exercise intensity that corresponds to the (MLaSS) in adolescent, endurance trained runners, (2) to examine possible between sex differences, and (3) to compare the MLaSS with commonly cited fixed blood lactate reference variables. The participants were first tested using a step-wise incremental treadmill test to establish the blood lactate profile and peak VO 2. The running speed and % peak VO 2 at the MLaSS were not significantly different to those corresponding to the fixed [BL& ] of 2.0 and 2.5 mmol-L-1 (P>0.05). The % HR max at 2.5 mmol-L-1 was also not different to that at the MLaSS, whereas at 2.0 mmol-L-1 it was slightly lower (P<0.05). The running speed, % peak VO 2, and % HR max at the fixed [BLa] of 4.0 mmol-L-1 were significantly higher than those at the MLaSS (P<0.05). In conclusion, it is clear that the MLaSS corresponded to the relatively high exercise intensity in this sample of athletes. It would appear that the running speed, % peak VO 2, and % HR max at the MLaSS lies somewhere between the fixed [BLa ] of 2.0 and 2.5 mmol"L-1. These results confirm earlier work that has suggested a fixed [BLa ] of 2.5 mmol-L-1 may be used with young people' to assess and monitor endurance running performance in place of the more commonly used 4.0 mmol-L-1 that has received so much attention in adult-based studies. The fourth study examined the effect of exercise training on endurance performance, blood lactate profile in relation to running speed (RV) and cardio respiratory function (peak V02) in adolescent runners. This study demonstrated that resting HR, LT and 1 Use of the expression young people is increasingly common since the publication of the text, Young People and Physical Activity by Armstrong and Weisman in 1997. It is used within this document to generically represent the 6 to 18 year age group. 11 RV, HR, V02 and peak V02 at LT were significantly influenced by endurance training. When running time, running velocity and run performance time pre and postintervention were included in the analysis, the intervention did not have a significant effect on peak VO2. When percentage body fat was included as a covariate, there was a positive association with pre and post-training for all groups. The conclusion from these data is that maturity and training both have an effect, especially at supra suggested training levels. The results of the four inter-linked studies support an age-related increase in endurance in aerobic and anaerobic performance and indicated significant differences between boys and girls. From a coaching viewpoint the results reveal that, from the age of 14 to 18 years, runners should be introduced to high intensity training and that changes to the format of middle distance running performance in adolescent competition are recommended.

Resumo: Objetivos: Analisar quais os principais fatores que influenciam a massa óssea de crianças e adolescentes avaliada pelo ultrassom quantitativo de falanges, e avaliar a massa óssea de adolescentes do sexo feminino, envolvidas em esportes com e sem sobrecarga corporal, utilizando o ultrassom quantitativo de falanges para verificar a influência da prática esportiva no tecido ósseo. Métodos: Este trabalho foi escrito no método alternativo, onde consiste de uma introdução, um artigo de revisão sobre o tema e um artigo original com os dados da pesquisa. No primeiro capítulo foi realizada uma revisão sistemática da literatura utilizando como referência as normas propostas pelo PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses). No segundo capítulo foi realizado um estudo transversal, no qual 192 adolescentes do sexo feminino divididas em três grupos: atletas de handebol (n=67), atletas de natação (n=62) e grupo controle (n=63) foram avaliadas pelo ultrassom quantitativo de falanges para avaliar a massa óssea através dos parâmetros AD-SoS e BTT, além de avaliados as variáveis de peso, altura, IMC e estádios de Tanner. Resultados: No primeiro capítulo foram incluídos 21 artigos na revisão sistemática, que apresentaram valores superiores de AD-SoS para as meninas em relação aos meninos durante o desenvolvimento fisiológico puberal. Os valores dos parâmetros do QUS de falanges aumentavam com o incremento do estágio maturacional. Variáveis antropométricas como idade, peso, altura, índice de massa corporal (IMC), massa magra demonstraram correlações positivas com os valores do QUS de falanges. A atividade física também demonstrou estar positivamente relacionada com o aumento da massa óssea. No segundo capítulo foram encontrados valores superiores de AD-SoS para as nadadoras em relação ao grupo controle, os dois grupos de atletas apresentaram valores superiores de BTT em relação ao grupo controle. Também foram encontrados valores superiores de AD-SoS para as atletas quando comparados os grupos pelos estádios de Tanner. Não houve diferença estatística entre os grupos de atletas e os parâmetros ósseos. Considerações finais: Na revisão da literatura os parâmetros AD-SoS e BTT como indicadores de massa óssea em crianças e adolescentes saudáveis demonstraram ser influenciados por variáveis como idade, altura, peso e desenvolvimento puberal, além de que o QUS de falanges demonstrou ser indicado para avaliar a massa óssea em populações pediátricas, podendo ser útil na identificação precoce de doenças osteogênicas. No estudo transversal foi possível observar que os parâmetros ósseos do QUS de falanges tem correlação com as variáveis de desenvolvimento maturacional, entretanto a atividade física frequente e programada exerce influencia positiva na massa óssea, sendo que a ação está mais associada com o tempo de prática e a frequência semanal de treinamento do que com as características das modalidades, seja com ou sem sobrecarga corporal
Abstract: Objectives: To analyze the main factors that influence bone mass in children and adolescents assessed by quantitative ultrasound of the phalanges, and to evaluate bone mass in female adolescents involved in sports with and without body burden using quantitative ultrasound of the phalanges to verify the influence of sports practice in the bone tissue. Methods: This dissertation was written in the alternative method, which consists of an introduction, a review article on the topic and a original article with the survey data. In the first chapter a systematic literature review using as reference the standards proposed by the PRISMA was performed. In the second chapter a cross-sectional study in which 192 female adolescents divided into three groups was performed: handball players (n=67), swimmers (n=62) and control group (n=63) were evaluated by ultrasonography quantitative phalanges to assess bone mass through the AD-SoS and BTT parameters, and evaluated the variables weight, height, BMI and Tanner Stage. Results: In the first chapter 21 articles was included in the systematic review, this articles showed higher values of AD-SoS for girls than boys during the pubertal development. The values of the parameters of QUS of phalanx increased with the increase of the maturational stage. Anthropometric variables such as age, weight, height, body mass index (BMI) and lean mass showed positive correlations with the values of QUS of the phalanges. Physical activity has also been shown to be positively associated with increased bone mass. In the second chapter, swimmers showed higher values of AD-SoS compared with the control group, the two groups of athletes had higher values of BTT compared to the control group. Higher values of AD-SoS for athletes were also found when comparing the groups by Tanner Stage. There was no statistical difference between the groups of athletes and bone parameters. Conclusions: In the literature review the AD-SoS and BTT parameters as indicators of bone mass in healthy children and adolescents. These parameters were influenced by variables such as age, height, weight and pubertal development, and that QUS of phalanx proved to be suitable for measuring bone mass in pediatric populations, and may be useful in early diagnosis of osteogenic diseases. In cross-sectional study we observed that bone parameters of the QUS phalanges correlates with variables of maturational development, however frequent and scheduled physical activity exerts a positive influence on bone mass, and the action is more associated with the practice time and weekly frequency of training than with the characteristics of modalities, either with or without body weight-bearing

Abstract:

Adolescence is a crucial period for bone development and exercise can enhance bone acquisition during this period of life. However, there is a lack of scientific evidence on how different loading sports practiced during adolescence can affect bone development in males. The present thesis is part of the PRO-BONE study and aimed to investigate the cross-sectional and longitudinal effects of participation in football (osteogenic sport), swimming and cycling (non-osteogenic sports) on bone mass, bone geometry, texture and bone metabolism in adolescent males. An active control group has been included too. Additionally, the thesis examined the effect of a 9-month jumping intervention programme on bone outcomes in adolescent males involved these sports. Cross-sectional findings from Chapter 4 show that footballers have better bone status than swimmers, cyclists and controls (7 to 21 %), and that there are no differences between participants of non-osteogenic sports and controls. Chapter 5 identifies that lean mass is the strongest determinant of bone outcomes, followed by football participation and height in adolescent male athletes, whereas the contribution of the other predictors, such as nutrition, physical activity and fitness, is site specific. Longitudinal evidence in Chapters 6 and 7 show that bone mass (5 to 8 %) and geometry (4 to 10 %) is higher in adolescent male footballers compared to swimmers and cyclists after one year of sport specific training, and that there are no differences in bone development between non-osteogenic sports groups and controls. Chapters 8 and 9 indicate that a 9-month jumping intervention programme can improve bone outcomes only in male adolescents participating in swimming and cycling (4 to 13 %), but not in those engaged in football, while it can improve fitness outcomes in all 4 groups (4 to 8 %). Collectively, the present thesis contributes to the literature by providing novel evidence in adolescent male athletes on the effects of popular sports such as football, swimming and cycling on bone status and development, and that a jumping intervention programme can improve bone development in those involved in non-osteogenic sports.

Abstract:

This project studied 108 Israeli youth of mixed gender, aged 12-16 (mean 12.8, SD 1.67), selected for risk, with a 3 to 1 ratio of boys to girls. It included a group given a sports intervention and a comparison group. It utilised a broad psychosocial approach to investigate risks for psychological disorder and the impact of an intervention, based on both an Ecological and Attachment theoretical approach to inform identification of risk and resilience factors in a society used to political conflict. Aims: i) to examine psychosocial risks for psychological disorder in both groups and (ii) to examine the impact of a sports intervention in reducing risk and symptoms and increasing resilience. Method: The two phased prospective study included 60 young people referred by social services to a cycling intervention and 48 to a comparison group. Phase 1 examined demographic characteristics and psychosocial risks in the combined groups in relation to behavioural, emotional and post traumatic symptoms. Phase 2 examined change after 9 months comparing the two groups. Standardised self-report questionnaires were used, with focus groups and qualitative interviews to establish intervention impact. Questionnaires were translated into Hebrew and Arabic, with focus groups held in the local languages and subsequently translated and interviews with coaches held in English. Results: Twenty-three percent of all the youth reported a behavioral or emotional disorder at case level, with 33% having symptomatology at borderline level. Risk factors for such disorder were deprivation, insecure attachment style, peer problems and affectionless control in childhood from mothers or fathers. Poor peer relationships mediated between childhood experience and disorder. Over half had exposure to a traumatic event and there was a high prevalence of partial Post Traumatic Stress Disorder ( PTSD): 31% and 6% with full disorder. Life events, trauma experience, ethnicity and deprivation associations provided evidence of a social and Ecological interpretation of findings. Childhood experience, insecure attachment style and peer relationships supported an Attachment perspective. Findings at follow-up showed positive effects of the cycling intervention through decreased self-esteem and symptoms for both Conduct disorder and PTSD. There was also increased support for those in the intervention. However, follow-up findings were limited by high attrition rates. Analysis of focus groups and interviews led to a descriptive model showing benefits of the intervention through agentic (skills, discipline), escapist and aesthetic (fun) aspects. Conclusion: Findings are discussed in relation to Israeli culture and post-conflict context on youth risk and disorder, and the use of similar interventions in other post-conflict zones.

Abstract:

Participation in recreational and formal sports can play a vital role in enhancing adolescents&rsquo
wellbeing. Research indicates that involvement in different forms of recreation and physical activities offer beneficial effects on the physical and mental health status of individuals. Sports participation has also been associated with lowered obesity, multiple risk behaviours, smoking and substance abuse. In South Africa rural and urban areas are increasingly affected by violence and a range of psychosocial problems such as youth crime, substance abuse and alcohol abuse. The aim of this research project was to explore the perceptions of community leaders of the role of sports participation in dealing with psychosocial problems amongst adolescents in a rural area. A qualitative approach was adopted to explore the perceptions of community leaders. Purposeful sampling was used to select participants according to the criteria set by researcher. The data was collected through the process of 10 indepth, semi-structured interviews with Afrikaans speaking community leaders, male and female from the two rural towns in the Cederberg region namely, Lamberts Bay and Clanwilliam. The semi-structured interview schedule consisted of five open-ended questions. A thematic content analysis was used to interpret the information. The study revealed that community leaders perceived sports participation as a protective factor against psychosocial problems within the community. They discussed sports benefits under three broad themes namely, health benefits, societal benefits and emotional benefits. The study further revealed poor financial resources, transport and poor facilities to be the major constraints for sports participation in their area. Future studies which explore the role of sports participation should include more information from a female&rsquo
s perspective, to enrich and understand the benefits of sports participation amongst females in the community.

Abstract:

Although sports and other forms of physical activities are associated with numerous health benefits, adolescent sports injury has emerged as an important public health problem. As the most immediate caregivers for athletes, coaches are expected to play an important role in preventing and reducing injuries, -considering that sports medical staff, such as athletic trainers are not always available to care for athletes. However, research on coaches' beliefs and practices related to injury prevention has been limited to coaching competency issues, in which injury prevention is considered only one component. Therefore, the purpose of the study was to describe the coaches' beliefs and knowledge pertaining to sports injury and their readiness for injury prevention practice to be incorporated into high school settings. The research questions are: (1) What are the coaches' beliefs and knowledge related to sports injury and their readiness for injury prevention practice?; (2) What are the relationships between coaches' beliefs and knowledge pertaining to sports injury and readiness for injury prevention practice?; and (3) What are the differences in coach-related factors between the coaches who have medical staff and those who do not? The participants in the study had average to low perceptions regarding injuries on their team. The knowledge score related to sports injury was not high. However, a majority of the coaches showed strong beliefs in favor of implementing injury prevention interventions as an effective way to prevent and reduce sports injuries. Supporting previous studies, the present study revealed strong associations between self-efficacy and the injury prevention behaviors assessed. It was also found that coaches who employed medical staff were approximately four times more likely to provide injury prevention programs to their athletes and have emergency plans. Findings from this study will provide a broader understanding of coaches' perceptions regarding sports injury, injury prevention interventions conducted by coaches, and the implications for developing quality coaching programs and policies to prevent and reduce sports injuries.

Abstract:

The purpose of this investigation was to examine whether sports in which boys participated spontaneously (i.e., not organized as a treatment) could be associated with the retrenchment of later adolescent delinquent behaviours. The objectives of this particular investigation were to: (i) observe how this participation might alter a negative behavioural developmental trajectory; and (ii) study the possible effects of transition in sports activity (i.e., increases or decreases in participation in sports from year to year) on current and later risk for delinquency.
This investigation utilized data obtained from the Montreal Longitudinal-Experimental Study of Boys which started in 1984 when the boys were six years old. Seven-hundred-eleven of the subjects met the inclusion criteria necessary to participate in the present study. Each year, from 1989 (age 11) to 1995 (age 17) the subjects were asked to complete the Self-Report-Delinquency questionnaire, a 27-item scale detailing their involvement in antisocial behaviour over the previous 12-month period. The scores of four of these years were retained for study; namely, those for 1989 (age 11), 1991 (age 13), 1993 (age 15), 1995 (age 17). (Abstract shortened by UMI.)

Abstract:

A number of computerised tests have been especially developed to facilitate the medical management of the sports-related concussion. Probably the most widely used of these programmes is the ImPACT test that was developed in the USA and that is registered with the HPCSA for use in the South African context. A recent Afrikaans version of the test served as the basis of the present study with the following objectives: (i) to collect Afrikaans ImPACT normative data on a cohort of Afrikaans first language adolescent rugby players with Model C education for comparison with existing South African English first language adolescent rugby players with Private/Model C schooling, and (ii) to investigate the pre-versus postseason ImPACT neurocognitive test profiles of this cohort of Afrikaans first language adolescent rugby players versus equivalent noncontact sports controls. The results for Part 1 of the study generally demonstrate poorer performance in respect of the Afrikaans cohort, which is understood to be the result of poorer quality of education. The results for Part 2 demonstrated failure of the rugby group to benefit from practice on the ImPACT Visual Motor Speed composite score to the same extent as the control group. It is argued that this apparent cognitive vulnerability in the rugby group is due to lowered cognitive reserve capacity in association with long term exposure to concussive and sub-concussive injury.

Abstract:

Background: A topic more frequently discussed nowadays is orthorexia nervosa (ON), which is an atypical eating disorder where the person is obsessed with healthy eating to avoid illness and disease. Signs of ON often begin with a wish for getting rid of bad habits, such as eating meals containing a lot of sugar and fat. Eventually the person’s behaviour changes and eating healthy becomes an unhealthy obsession that takes over the everyday life. Recently, it has also been related to excessive training, especially in Swedish media. Furthermore, it has been shown that athletes are at higher risk for developing ON. However, there is insufficient research in this area, as well as the ON prevalence among adolescent girls and correlation between ON and body mass index adjusted for children and adolescents. To investigate this, as well as the correlation between ON and hand strength, which is used as an indicator of general muscle strength, is therefore of great importance. Aim: The aim of this study was to compare ON prevalence among adolescent girls in seventh grade in a sports secondary school and adolescent girls in seventh grade in general secondary schools and investigate the correlation between ON and BMI and ON and hand strength. Method: A total of 48 girls in seventh grade participated in the study: 28 girls from the sports secondary school and 20 girls from the general secondary schools. To investigate the ON prevalence the questionnaire ORTO-15 was used. To calculate BMI standing length and body weight was measured and thereafter adjusted to the cut-off points constructed by the International Obesity Task Force. Hand strength was registered with a hand grip dynamometer. Results: There was no significant difference in ON prevalence between the girls in the sports secondary school and the general secondary schools. However, a majority of all girls had an indication of ON. Furthermore, a higher indication of ON had a small correlation with both a higher BMI and a higher muscle strength. Conclusion: More studies and better instruments are needed to further investigate ON prevalence among adolescent girls, as well as relationships between ON and BMI and ON and hand strength. Interesting to consider in further research is also how these variables evolve over time in persons with ON.

Abstract:

Recent research has suggested that the effects of sport on well-being are mediated by psychological characteristics such as physical self-concept, instrumentality and positive body images; in addition, sport was found to be related to these psychological benefits for high school girls. However, physical self-concept played a central role by mediating the sport -body image and sport instrumentality relationships. Positive body image and instrumentality, in turn, predicted greater psychological well-being. The purpose of this investigation was to replicate earlier studies, and to examine these relationships with non-sport physical activity. Sport and physical activity were expected to contribute to higher physical self-concept, which in turn, would contribute positively to instrumentality and body image. Further, instrumentality and body image would be positively related to psychological well-being. Participants were 355 9th (n = 170) and 10th (n = 193) graders and they completed measures of involvement in sport/physical activities, physical self-concept, instrumentality, body satisfaction, self-esteem, satisfaction with life, depression, and demographics. Structural equation modeling was utilized to analyze the data. Overall, for both sport and physical activity, the models fit the data well (sport model: NNFI=.95, CFI=.96, SRMR=.08, RMSEA=.09, physical activity model: NNFI=.96, CFI=.97, SRMR=.08, RMSEA=.09). Specifically, sport participation was positively related to physical self-concept (R2 = .47); physical self-concept related to body image (R2 = .30) and instrumentality (R2 = .23); Physical activity was positively related to physical self-concept (R2 = .61); physical self-concept related to body image (R2 = .30) and instrumentality (R2 = .26). For both models, positive body image and higher levels of instrumentality contributed to greater psychological well-being (R2 = 66). These results highlight the importance of developing physical competence for high school girls through sport participation and physical activity.

Abstract:

The aim of this narrative research was to explore the relationship between lifestyle and self-confidence within adolescent football players. The research questions were formulated as follow; (1) What sources let adolescent football players build self-confidence? (2) What issues characterize adolescent football player’s lifestyles? (3) How do adolescent football players perceive an association between lifestyle and self-confidence in sport? The results showed eight different sources for building self-confidence, where earlier performances and social support were considered as the strongest. Ten different lifestyle factors were observed. Football, social support, performance intent and good health were common factors for all the participants. The study showed three types of perceived associations between self-confidence and lifestyle. First of all, there is an overlap between the lifestyle issues and sources of self-confidence. Second lifestyle issues influence the degree to which sources of self-confidence work for the participant to build self-confidence. Third lifestyle pattern provides a balance (or misbalance) which influences particular sources of self-confidence and in the end self-confidence itself. The author discuss how the result can be interpreted in perspective of every single participant and in common for all the participants.

Abstract:

The purpose of this project was to design and evaluate a sport-based life skills intervention designed for indigenous New Zealand (Maori) youth who may be exposed to drug or alcohol abuse. An indigenous research approach known as Kaupapa Maori research was utilised. As an indigenous approach, Kaupapa Maori signifies the importance of research with Maori being initiated, determined, and validated by Maori and in particular, by those directly involved with the research initiative (Bishop, 1996; Tuhiwai-Smith, 1999). As a result of adhering to a Kaupapa Maori approach the participants determined additional areas of interest including academic self-esteem, intrinsic motivation for schoolwork and career awareness. Therefore, the initial project grew to include several other life skills areas identified by the participants. The life skills basis of the 'Hokowhitu' intervention was adapted from the Going for the Goal (GOAL) and Sports United to Promote Education and Recreation (SUPER) programmes developed by Professor Steve Danish (Danish, 1997; Danish & Nellen, 1997; Danish, Meyer, Mash, Howard, Curl, Brunelle & Owens, 1998). The GOAL and SUPER programmes taught life skills to adolescents including informed decision-making, health-enhancing activities (e.g., goal setting) and health-compromising activities (e.g., drug & alcohol abuse). A New Zealand (NZ) version of the GOAL programme was successfully pilot-tested in 1997-1998 in NZ schools with non-Maori adolescents (Hodge & Danish, 1999; Hodge, Cresswell, Sherburn, & Dugdale, 1999). The evaluation of the Hokowhitu programme used both quantitative and qualitative analyses. The qualitative investigation received an enthusiastic response and supportive results for the Hokowhitu programme. Many of the research participants preferred the qualitative investigative approach because of the culturally recognised components (e.g., Te kanohi ki kanohi or face-to-face method used to ask questions). The quantitative investigation used; Mann-Whitney U, Wilcoxon, Chi Square and McNemar statistical tests (Harraway, 1995). The outcome of the overall programme evaluation showed that the Hokowhitu programme provided improvements in; (a) academic self-esteem, (b) increased intrinsic motivation for schoolwork, (c) increased career awareness, and (d) increased drug and alcohol awareness in adolescent Maori. Also, there was some statistical support for the Hokowhitu programme and evidence that life skills and Kaupapa Maori ideologies were able to be successfully integrated into a sport-based programme.

Abstract:

The purpose of this study was to find whether cross training could improve male adolescent rugby skills. Three major sports (soccer, basketball and wrestling) were selected to form the base of the cross training intervention program. Pre- and post-tests were performed with the entire rugby squad (24 participants) prior to and at the conclusion of the intervention program. After pre-testing, the participants were grouped into either the intervention (12) or the control group (12). Supervised cross training sessions were performed twice a week for 10 weeks as well as traditional rugby training twice a week for 10 weeks with the intervention group. The control group performed supervised conventional rugby training twice a week for 10 weeks. All participants (24) played in a rugby match once a week during the 10 week period of the study.

Abstract:

This study explored elite female adolescent swimmers' perceptions of the motivational influences of their coaches, parents, and peers using qualitative methods. Nine elite female swimmers (aged 13--15 years) participated in two semi-structured interviews that were audiotaped and transcribed verbatim. Data was gathered and analyzed according to Interpretive Phenomenological Analysis (Smith & Osborn, 2003). Six categories emerged including: individual factors, and assistance, informational, esteem, emotional, and network support. Results indicated girls' interpretations and unique, salient aspects of social support types provided by coaches, parents, and peers. Findings are related to past self-determination theory (SDT; Deci & Ryan, 1985) motivational research. In particular, swimmers social support experiences were uniquely linked to their perceptions of competence, autonomy, relatedness, and motivation in elite competitive swimming. Findings support main SDT tenets and offer new insights into the important and differential social support influences in sport.

Abstract:

Att samtidigt göra en satsning på sin idrott och skolan ställer krav på individen. Dessa krav kan leda till idrottsrelaterad utbrändhet. Att hitta faktorer som påverkar idrottsrelaterad utbrändhet är viktigt för att kunna förebygga och förhindra problemet. Många olika faktorer har visat sig påverka och en faktor som behöver undersökas noggrannare är den sociala faktorn. En sådan social faktor är tränare- aktiv relationen. Syftet var att undersöka om det finns något samband mellan symptom av idrottsrelaterad utbrändhet och den upplevda kvalitén på tränare- aktiv relationen. En enkätundersökning genomfördes av 107 idrottsgymnasieelever (34 tjejer och 73 killar) i åldrarna 15-18 år. Idrottsrelaterad utbrändhet visade sig vara negativt korrelerat med tränare- aktiv relationen. Underkategorin Complementary visade sig vara den som visade starkast samband med idrottsrelaterad utbrändhet. 16 procent av eleverna på skolan upplevde höga symtom. Instruktörer på skolan bör fundera igenom deras relationer med eleverna och hur dessa kan förbättras för att reducera problemet. Idrottsgymnasier borde fundera kring både hur kraven både inom skolan och inom elevernas respektive idrott ser ut under de tre gymnasieåren.

Resumo: Para melhorar a forma física, atletas geralmente enfrentam períodos intensos de estresse físico seguidos de uma diminuição no nível desse estresse com o intuito de gerar adaptações a nível celular. Por esse motivo, esforços extensos são realizados no intuito de quantificar objetivamente o fino balanço entre a intensidade do treinamento e a capacidade de tolerância do atleta, onde o monitoramento de diferentes variáveis durante uma temporada esportiva pode contribuir na modulação das cargas de treinamento. Dentre essas variáveis, destacam-se os parâmetros do sistema imunológico como um dos fatores importante na preparação do atleta durante a temporada esportiva, pois supressões temporárias da resposta imune às ameaças ambientais podem levar à ocorrência de infecções do trato respiratório superior (ITRS), o que pode influenciar drasticamente a preparação e a capacidade competitiva de atletas. Não foram observados estudos que realizaram o monitoramento da resposta imune de atletas adolescentes durante os diferentes períodos de uma temporada esportiva, principalmente quando engajados em esportes coletivos ou times esportivos, muito populares nesta faixa etária. Assim, o objetivo do presente estudo foi monitorar as respostas imunológicas, hormonais e a incidência de ITRS de atletas adolescentes de basquetebol durante duas temporadas esportivas. Na primeira temporada, as contagens leucocitárias, incidência de sintomas de ITRS e as mudanças das cargas de treinamento foram monitoradas antes (M1) e após 8 semanas (M2), equivalente ao período preparatório da temporada esportiva realizada no ano de 2010. Foram observadas: diminuições nos monócitos no M2 comparado ao M1(p = 0,004); cargas de treino da semana 6 foram maiores comparadas às semanas 1, 2, 4 e 8 (p < 0,05); Semanas 1 e 2 apresentaram maiores incidências de ITRS. Nossos resultados demonstraram que as variações nas cargas de treinamento semanal não se correlacionaram com as ocorrências de ITRS auto-reportadas, sugerindo assim que esta população pode ter uma resposta atenuada nas perturbações do sistema imune relacionadas ao exercício. Na segunda temporada, as respostas imunes, hormonais e a incidência de ITRS foram monitoradas antes (Pré-Temporada) e após 6 (Preparatório) e 20 semanas (Competitivo) da temporada esportiva realizada durante o ano de 2011. Foi observado: aumento significante (38%) na ocorrência de ITRS no período competitivo comparado ao preparatório; aumento significativo de monócitos (p=0,0054), cortisol (p=0,0002), TNF-? (p=0,0001) e PCR (p=0,0017) e diminuição da IL-10 (p=0,0077) no momento Competitivo comparado ao momento Pré-Temporada. Os resultados do presente estudo sugerem que o aumento das ocorrências de ITRS experimentadas por atletas adolescentes durante a etapa competitiva pode ser decorrente dos efeitos indesejados do processo inflamatório em resposta a possíveis microtraumas musculares, uma vez que as respostas imunológicas destes indivíduos parecem estar adaptadas aos diferentes períodos da temporada esportiva. Ainda, o estado inflamatório e catabólico evidenciado ao final da etapa competitiva não foram capazes de prejudicar no desempenho neuromuscular e funcional de atletas adolescentes de basquetebol
Abstract: To improve physical performance, athletes often use periods of heavy physical stress followed by a reduction in stress level to achieve specific adaptations at the cellular level. Therefore, extensive efforts are made to quantify objectively the fine balance between training intensity and athlete's tolerance, where monitoring of different variables during a sports season can contribute to the modulation of loads during the training process. Among these variables, we highlight the immune system parameters as important factors in the preparation of the athlete during the sports season because temporary suppressions of the immune response to environmental threats can lead to occurrence of episodes of upper respiratory tract infections symptoms (URTI), which can dramatically influence the preparation and competitive programs of an athlete. No studies were found that aimed to monitor the immunological responses for different training periods in adolescents athletes engaged on team sports, which are very popular in these age groups. Thus, the objective of this study was to evaluate the immune and hormonal responses and the occurrence of episodes of URTI in a group of adolescent male athletes during two basketball seasons. In the first season, the WBC counts, incidence of URTI symptoms and changes in training loads were monitored before (M1) and after 8 weeks (M2), equivalent to the preparatory period of the sports season held in 2010. There were found a significant decrease in monocytes at M2 compared to M1 (P = 0.004). There were no significant alterations in total leukocytes (P = 0.07), neutrophils (P = 0.07), or lymphocytes (P = 0.09). No significant changes in plasma concentrations of TNF-? (P = 0.30) or IL-6 (P = 0.90) were found. The weekly load from week 6 was higher when compared with weeks 1, 2, 4, and 8 (P < 0.05), and week 8 was the lowest when compared with week 5 (P < 0.05). Self-reported URI incidences were highest at weeks 1 and 2. Our results demonstrated that variations in weekly training load during the preparatory period were not correlated with changes in self-reported occurrence of URI incidences, suggesting that adolescent athletes may have an attenuated response to exercise-induced perturbations to the immune system. In the second season, the immune and hormonal responses and the incidence of URTI were monitored before (Pre-Season) and after 6 (Preparatory) and 20 weeks (Competitive) of the sports season held during the year 2011. There were found significant increase (38%) in the occurrence of URTI during the Competitive moment as compared to Preparatory. There were found significant increases in monocytes (p=0.0054), cortisol ((p=0.002), Tumor necrosis factor-? (p=0.0001) and C-reactive Protein (0.0017) in the Competitive moment as compared to Preparatory, as well as a decrease in interleukin-10 (p=0.0077) at the same moments of evaluation. The results of this study suggest that increased occurrence of URTI experienced by adolescent athletes during the competitive stage may be due to the unwanted effects of an inflammatory process in response to muscle micro-trauma since the immune responses of these individuals seems to be adapted to the different periods of the sports season. In addition, the inflammatory and catabolic states observed at the end of the competitive stage were not able to affect the neuromuscular and functional performances in adolescent basketball athletes

Abstract:

The purpose of this study was to determine the existence and extent of the relationship of coaching styles and adolescent athletes in terms of Self Determination Theory (SDT). Specifically, this study adapted Baumrindâ€™s parenting styles of authoritative, authoritarian, and permissiveness to coaching styles and examined the relationship between each coaching style and the tenets of SDT, namely competence, autonomy, and relatedness. This study also examined the effect of the number of years an athlete participated in a chosen sport, the number of years played on a specific team, and the number of years played for a particular coach. The sample consisted of 194 Brigham Young University students who had participated in either club or high school level sports for at least one year while in high school. Study participants completed the Basic Needs Sports Satisfaction Scale (BNSSS) and a sports-adapted version of the Parenting Authority Questionnaire (PAQ). Results from block entry method linear multi-regression analysis suggested Baumrindâ€™s Parenting Typology could in fact be successfully applied to adolescent sports and that coaching style could impact athletesâ€™ levels of perceived autonomy, and competence. Results revealed that an authoritative coaching style was a significant predictor of athlete autonomy and competence while an authoritarian coaching style was a significant negative predictor of athlete autonomy levels. Results hold practical implications for coaches, athletes, parents, and league administrators.

Abstract:

Nutrition knowledge, dietary intake, body composition and perceived sport performance were measured before and after an eight week nutrition intervention. The sample consisted of eleven male high school football athletes aged 14-18 years old. Baseline nutrition knowledge was higher than anticipated but fruit and vegetable intake was low. As a result of the nutrition intervention, vegetable intake improved from 0.94 servings per day to 2.02 servings per day (p=0.02). Of the eleven subjects in the study, eleven conceded to both performing and feeling better as a result of the nutrition intervention. The present study suggests that a nutrition intervention can improve dietary intake and perceived sport performance among adolescent athletes.

Abstract:

Adolescent athletes with type 1 diabetes (T1DM) face unique challenges when compared to peers with and without diabetes. Continuous subcutaneous insulin infusion (CSII) provides a method of insulin delivery that can enhance flexibility in insulin regimens and lifestyle that may be especially appealing to the adolescent athlete. No studies have explored the impact of athletics in this population. This descriptive qualitative study explored and described the experiences of adolescent athletes using CSII as their primary insulin delivery method, with a focus on athletic participation and performance. The purposeful sample consisted of four adolescent athletes, ages 13 to 15 years with T1DM, using CSII, in excellent diabetes control, and recently participated in organized sports activities. After written informed consent, data were collected through a semi-structured interview with the adolescent and parent. Results were transcribed verbatim and analyzed for emerging themes. Four themes emerged from the transcripts along with multiple subcategories. The main themes included: protecting the pump and infusion site; dealing with highs and lows; maximizing participation and performance; and keeping watch. Information gathered from this study will prepare healthcare professionals to anticipate the needs of adolescent athletes using CSII when prescribing a diabetes management regimen.
