Bakgrund: Medvetenhet om kropp och rörelse nämns ofta som en viktig fakor i att öka prestationsförmåga, undvika skador, nå högre livskvalitet och förbätta sjukdomstillstånd. Det har länge funnits ambitioner att förbättra rörelse genom ökad medvetenhet. Feldenkraismetoden är en metod för att förbättra rörelse genom förhöjd rörelsemedvetenhet och är förenlig med nutida vetenskap men förhållandevis lite empirisk forskning stöder metodens effektivitet. De flesta tidigare studier har varit på någon form av dysfunktion och ofta subjektiv upplevelse snarare än objektiva värden. Det har varit svårt för Feldenkraispedagoger att finna rätt mätmetoder för att utvärdera metoden. Syfte: Studiens syfte är att utvärdera effekten av träning för ökad rörelsemedvetenhet enligt Feldenkraismetoden på rörelse hos friska personer genom kvantitativ mätning. Metod: Friska kvinnor i en experimentgrupp (n=4, 30±7 år) och en kontrollgrupp (n=4, 26±2 år) testades med fem kvantitativa rörelsetester; one-leg standing balance, one-leg standing long jump, standing triple jump, star excursion balance test och upper quarter Y-balance test, innan och efter en intervention ledd av en auktoriserad Feldenkraispedagog där experimentgruppen genomgick tio träningsfällen enligt Feldenkraismetoden under fem veckors tid. Resultat: Signifikant förbättring (P≤0,05) i förhållande till både förtest och kontrollgrupp sågs vid star excursion balance test för vänster ben. Slutsats: Träning för ökad rörelsemedvetenhet enligt Feldenkraismetoden verkar kunna leda till förbättring i kvantitativt mätt rörelse hos friska kvinnor. Vidare forskning med fler deltagare är nödvändig för att bättre besvara hypotesen att träning för ökad rörelsemedvetenhet genom en intervention med Feldenkraismetoden leder till förbättrade resultat i de utvalda testerna hos friska personer.<br>Background: Awareness of body and movement is often mentioned as an important factor in increasing performance ability, avoiding injury, reaching a higher quality of life and improving conditions of illness. There has long been an ambition to improve movement through increased awareness. The Feldenkrais method is a method for improving movement through increased movement-awareness and is compatible with modern science. but comparatively little empirical research supports the methods effectivity. Most earlier studies have been on subjects with some form of dysfunction and often on subjective experience rather than objective measurements. It has been challenging for Feldenkrais-practitioners to find suitable ways of measurement for evaluating the method. Purpose: The purpose of this study is to evaluate the effect of training for increased movement-awareness according to the Feldenkrais method on movement in healthy subjects by quantitative measurements. Method: Healthy women in an experiment-group (n=4, 30±7 years) and a control-group (n=4, 26±2 years) were tested with five quantitative movement-tests; one-leg standing balance, one-leg standing long jump, standing triple jump, star excursion balance test and upper quarter Y-balance test, before and after an intervention where the experiment-group went through ten training sessions according to the Feldenkrais method during five weeks time. Results: Significant improvement (P≤0,05) in comparison to both pre-test and change in the control-group was seen for star excursion balance test of the left leg. Conclusion: Training for increased movement-awareness according to the Feldenkrais method seem to be able to improve quantitatively measured movement in healthy women. Further research with more participants is necessary to better answer the hypothesis that training for increased movement-awareness in accordance with the Feldenkrais method leads to improved results in the chosen tests in healthy persons.

Introduction: The National Hockey League Entry Draft Combine (NHLED Combine) is considered one of the toughest physical fitness tests an ice hockey player has to go through. The NHLED Combine consists of several fitness tests evaluating the athlete’s aerobic- and anaerobic capacity; lower body power, upper body strength and power, flexibility and anthropometrics; no lower body strength test are employed. Squats are the only exercise used by all National Hockey League (NHL) strength and conditioning coaches yet it is not included in the NHLED Combine. Purpose: The purpose of this study was to determine which off-ice test correlates best with on-ice performance measured as forward skating speed. We hypothesised that squat one repetition maximum (squat 1RM) would be a better or equal predictor of on-ice performance compared to the current NHLED Combine tests standing long jump (SLJ) and Wingate anaerobic test (WAnT). Method: Eleven male subjects, aged 17.8 ± 0.8 years, performed an on-ice sprint followed by the off-ice tests SLJ, WAnT and squat 1RM. Results: A correlation was found between sprint time on-ice and SLJ (r= -0,727, p= 0.006), Wingate anaerobic test mean power/ body weight (WAnT MP/BW) (r= -0,607, p= 0,024), squat 1RM (r= -0,600, p= 0.026) and squat 1 repetition maximum/body weight (squat 1RM/BW) (r= -0,609, p= 0.023). Conclusion: The results indicate that squat 1RM and squat 1RM/BW are equally good predictors of hockey performance as SLJ and WAnT MP/BW.<br>knäböj, hockey, is, nhl, skridskoåkning, skridskoskär, sprint, horisontalhopp, wingate, styrka, kraftutveckling, fystest

Athletic performance assessments are important for identifying physical giftedness, monitoring athlete progress and supporting training recommendations. Sprint performance is a key component in athlete success both in athletics and field-based sports, and talent identification testing batteries often include sprint and jump assessments. Jumping and sprinting share a number of similar characteristics and research has shown that the relationships between sprint and jump tests depend on the recorded segment of the sprinting task, type of jump performed, and the speed and sex of the athlete. The majority of this research has been conducted in small, single sex, similar athlete cohorts and there has yet to be an analysis of a large cohorts multi-sport population with both male and female groups. Understanding the relationships between sprint ability and horizontal jump performance, based on large groups of athletes separated by sex can provide great insight into the shared and independent value of sprint and jump performance tests to support athlete testing and development. Therefore, the purpose of this study was to investigate the relationships between horizontal jump tests and sprint performance within different athlete sexes and sprint ability. To the authors’ knowledge, this is the first study with a large population sample of multisport athletes, with differing sprint and jump abilities. The associations and relationships between horizontal jump performance in standing broad jump (SBJ) and standing triple jump (STJ) with 0-10m and 30-40m sprint time in a group of athletes participating in a talent identification event were investigated in this study. Correlations and linear regressions were assessed with athletes grouped only by sex (male (n = 742), and female (n = 610)), and then grouped by sex and speed (fast = -0.5 SD, slow = +0.5 SD) for both 0-10m and 30-40m time separately. When grouped only by sex there were very large and large associations between sprint and jump measures (r = -0.533 to -0.717), and linear regression equations explained 37.4% to 55.5% of the variance. When grouped by sex and speed, slow athletes showed stronger associations (r = -0.353 to -0.488) than fast athletes (r = -0.088to -0.307). Linear regressions explained 20.3% to 28.5% of the variance in slow athletes, but only up to 12.0% of the variance explained in fast athletes. Linear regressions in slow and fast males all included SBJ as a predictor, but not STJ. Linear regressions in slow and fast females all included STJ as a predictor, but not SBJ. Overall, these results support the use of general sprint and jump tests for slower athletes, the importance of both sprint and jumps tests with higher resolution in faster athletes, as well as the utility of different jump tests to evaluate lower limb performance between sexes.<br>Graduate

Lower body explosive power (LBEP) forms a critical component in any individual and team sport performance and it is therefore essential to develop a means of predicting LBEP in adolescents for early identification of future talent in various sporting codes. LBEP is frequently used by athletes during matches or competitions where explosive movements such as jumping, agility running and sprinting are required for successful performance. These movements are usually found in individual sports such as long jump and high jump as well as in team sports such as basketball, volleyball and soccer. To date not much literature is available on LBEP, especially with regard to LBEP prediction models. Furthermore, studies on adolescents are scarce and a LBEP prediction model has not yet been developed for a South African adolescent population. It is against this background that the objectives of this study were firstly, to develop a LBEP prediction model from various physical and motor performance components among a cohort of adolescents living in the Tlokwe local municipality of Dr Kenneth Kaunda district in the North-West Province, South Africa; and secondly, to develop a LBEP prediction model from several anthropometric measurements among a cohort of male and female adolescents living in the Tlokwe local municipality of Dr Kenneth Kaunda district in the North-West Province, South Africa. Two hundred and fourteen (15.8±0.68 years) 15-year-old adolescents (126 females, 88 males) from 6 surrounding schools within the Tlokwe local municipality of Dr Kenneth Kaunda district in the North-West Province of South Africa were purposefully selected from pre-acquired class lists took part in the study. Data was collected by means of various questionnaires as well as anthropometrical, physical and motor performance tests. For representation of LBEP a principal component factor analysis was done and the results indicated that the vertical jump test (VJT) was the best indicator of LBEP in the cohort of adolescents. With regard to the anthropometrical related LBEP prediction model, the forward stepwise regression analysis yielded a correlation coefficient of R2 = 0.69. The following variables contributed significantly (p≤0.001) to the anthropometrical LBEP prediction model: stature (57%), muscle mass percentage (10%) and maturity age (3%). The LBEP prediction model that was developed equated to LBEP (vertical jump) = -136.30 + 0.84(stature) + 0.7(muscle mass percentage) + 4.6(maturity age). Variables other than the variables that formed part of the study could explain the further 31% variance in the LBEP of the adolescents. The physical and motor performance LBEP prediction model indicated that gender (39%) and 10 m speed (7%) contributed significantly (p ≤ 0.001) to the overall prediction of the LBEP of the adolescents. The LBEP prediction model delivered a stepwise forward regression analysis coefficient of R2=0.458 and a prediction formula LBEP = 68.21 + 9.82 (gender) – 18.33(10 m speed). The remaining 56% of the variance in the results could be explained by other factors than the variables considered in the study. In conclusion, to the best of the researchers’ knowledge, this is the first study which has made an attempt at developing LBEP prediction models from the anthropometrical, physical and motor performance components of a cohort of adolescents of South Africa. The prediction models developed in the study will assist teachers sport scientists and sporting coaches who have limited resources available, to measure and calculate LBEP in adolescents, with the means to do so in South Africa. Further high quality studies are necessary to further improve and develop such prediction models for various age groups of adolescents in the greater South Africa.<br>MSc (Sport Science), North-West University, Potchefstroom Campus, 2014
