Abstract:

This pilot study examined the accessibility and usability of three weight training systems for athletes with spinal cord injuries. The systems were Universal Centurion II, Nautilus, and Keiser Cam II. Accessibility factors were direction of transfer, ease of transfer, and access of machine components. Usability includes use with/without assistance, necessary adaptations, and adjustability of resistance level and seat location. Also examined were minimum resistance level and feasibility of use without application of bilateral force. One 25-year-old male athlete with paraplegia (T5-6) served as the demonstrator for all evaluations. A matrix of accessibility and usability was constructed for 10 upper-body exercises that could be performed on at least two of the three weight training systems. Overall, the Keiser Cam II system was judged superior on accessibility and usability for spinal cord-injured athletes; however, the Nautilus system provided the most comprehensive upper-body workout.

AbstractThis study aimed to determine the patterns of injury associated with training activities in elite South Korean rowing athletes training for the Olympic Games. Data were prospectively collected between 2010 and 2019 at the Korea National Training Center in South Korea. Three sports medicine doctors assessed athletes, and the data were stratified according to sex, rowing style, weight class, site of injury, and severity of injury. The groups were compared using the c 2 test. The 95 % confidence interval with Poisson rates and exact Poisson test were used for comparison of rates. In total 514 injuries were recorded during the study period, with an average of 2.86 injuries per athlete annually; among these, over half (57.8 %) were mild injuries. Most injuries occurred in the lower extremities (42.0 %), followed by the trunk (30.2 %), the upper extremities (24.9 %), and the head and neck area (2.9 %). Weight class was significantly associated with severity of injury in all rowing athletes (p < 0.001), for both male and female rowing athletes (p = 0.006 and p = 0.014, respectively). Lightweight male athletes demonstrated higher incidence rate of injury than open-weight male athletes (p < 0.001). On the contrary, lightweight female athletes demonstrated lower incidence rates of injury than open-weight female athletes (p < 0.001). These findings on the incidence of training injuries and patterns based on rowing styles, sexes, and weight classes may elucidate the circumstances leading to injuries in elite Korean rowing athletes. Furthermore, these findings may contribute to the development of programs to enhance athletic performance and reduce the incidence of sports injuries.

Abstract:

Background:Little is known about the epidemiology of dog sport–related injuries. This study examines injuries among handlers and dogs in the sport of dog agility.Methods:A cross-sectional pilot study captured data on demographics, exposures, and injury for a sample of agility handlers and dogs. Logistic regressions predicted odds of injury.Results:Survey of 217 handlers and 431 dogs identified 31 handler injuries (1.55 training injuries per 1000 hours, 2.14 competition injuries per 1000 runs) and 38 dog injuries (1.74 training injuries per 1000 hours, 1.72 competition injuries per 1000 runs). Handlers most commonly injured knees (48.4%) and lower trunk (29.0%). Most common diagnoses were strains (51.6%) and sprains (32.3%). Obese handlers had increased odds of injury compared with normal weight handlers (OR = 5.5, P < .001). Dogs most commonly injured front paws (23.7%) and shoulders (15.8%). Most common diagnoses were strains (44.7%) and cut/scrapes (21.1%). Injury was positively associated with dog’s age (P < .05). Handlers more commonly reported positive physical, emotional, and social motivations for participation than competitive.Conclusions:Despite many health benefits, dog agility poses a risk of injury to both handlers and dogs. Future research on specific mechanisms of injury should drive evidence-based injury prevention strategies.

Abstract:

During training and competition, athletic dancers perform complex artistic movements that can lead to stress on the musculoskeletal system, making them subject to high risk of injury. The purpose of this study was to evaluate the prevalence, location, and nature of musculoskeletal injuries among dancesport athletes and to identify potential risk factors for injury. This cross-sectional study was performed at several national dancesport meetings in Italy. All 168 dancesport athletes who participated at the meetings were invited to complete a questionnaire related to injuries they may have suffered during the previous year; other information collected included demographic data (age, sex, height, weight), dance participation (discipline, categories), training (training duration, years since starting to dance), and injury (location, etiology). Of the 168 dancers, 153 completed the questionnaire. Of the 102 injuries reported, 73 athletes (47.7%) reported at least 1 injury. The locations of the injuries were the lower limbs (n=75, 73.5%), upper limbs (8, 7.8%), and spine (19, 18.7%). Significant differences were found in the injury location (p<0.01) as well as the nature of the injury (p<0.01). No significant differences were found between injured and non-injured athletes in demographic data, dance participation, and training variables (p>0.05). The results indicate that about half of the dancers reported at least 1 injury, with these being located particularly in the lower limbs and predominantly strain and sprain injuries. To reduce the prevalence of injuries, a prevention program may be indicated, with future research needed to identify appropriate strategies to prevent injuries.

Abstract:

ObjectivesWe aimed to determine the injury patterns associated with training activities in elite South Korean taekwondo athletes training for the Olympic Games.MethodsWe collected data prospectively from 2007 to 2016 at the Korea National Training Center in Seoul, South Korea. A sports injury was defined as acute or chronic musculoskeletal signs and symptoms due to taekwondo activities during training sessions. Athletes were assessed by an on-site sports medicine specialist. The elite taekwondo athletes were stratified according to sex, weight class (flyweight, featherweight, welterweight and heavyweight), injury location (body region and site) and injury severity (mild or level I, requiring treatment for 1–3 days; moderate or level II, requiring treatment for 4–7 days; or severe or level III, requiring treatment for ≥8 days).ResultsAthlete exposure was 56 160 training sessions that took 249 600 hours. 1466 injuries were recorded in 283 athletes, with an average of 4.6 injuries per athlete annually. Of these, more than half (56%) were mild injuries, with most injuries occurring in the lower extremities (65.5%), followed by injuries to the trunk (16%), upper extremities (14%) and head and neck area (4%). Among these athletes, women had higher injury rates in the featherweight and welterweight categories (P≤0.0001), but there were no sex differences in other weight categories. In general, female athletes and male athletes experienced a comparable risk of injury (relative ratio: 1.55; 95% CI 0.89 to 2.68).ConclusionIn elite South Korean taekwondo athletes, most injuries occur in the lower extremities and were graded as minor. Injury severity depended on weight class.

Abstract:

Purpose This study aims to analyze the risk factors and type of injuries occurring in Taekwondo athletes participating in a national competition. Methods Out of the 127 competitors, 18 athletes got injured during a Taekwondo championship who were analyzed for the following parameters: modality of training; age, weight; belt color; and the type of injury. Results Around 89% of the injuries were due to bruising and were found mainly on the lower limbs (61%) during the elimination rounds and during the first match of the day. The higher probability of injury was in the second round (56%), and during the first match of the day (72%). Nearly all the athletes were able to complete the game in which they were injured (83%). Comparing the average age of the athletes suffering an injury (23.6 ± 2.06 years) with their average years of training (8.4 ± 7.05 years) it can be noted that these athletes began this discipline rather late. The more is the training age and the weekly hours of training, the more are the numbers of matches completed, even as injured. Beginners with a low-level belt suffered more injuries than the experienced subjects did. Conclusion The following risk factors for injury were found: starting to practice in late age, weekly training sessions with a few number of hours, male sex, low-level belt, elimination rounds, the first match of the day, and second round. Level of Evidence Level III, observational analytic study without a control group.

ObjectivesTo report injury patterns associated with the training activities of elite male and female South Korean wrestling athletes preparing for the Olympic Games.MethodsFrom 2008 to 2017, we prospectively collected data on elite wrestling athletes at the Korea National Training Center. Athletes were assessed by two sports medicine doctors, and data were stratified according to sex, wrestling style, weight class, injury location and injury severity. Χ2tests were used to compare groups. Injury risk was expressed in relative ratios with 95% confidence intervals (RR, 95% CI).ResultsThere were 238 male and 75 female elite wrestlers. Training time totalled 382 800 hours. We recorded 1779 injuries in 313 athletes aged >18 years (annual average, 4.04 injuries/athlete); 59% of these were mild injuries. When all athletes were considered, most injuries occurred in the lower extremities (37.5%), followed by the upper extremities (27.4%), trunk (25.4%) and the head and neck area (9.7%). Weight class significantly influenced injury severity for both wrestling styles among male athletes (Greco-Roman, P=0.031; freestyle, P=0.028), as well as among female freestyle wrestling athletes (P=0.013). The relative ratio of injury incidence for the lightweight class compared with the heavyweight class was high for Greco-Roman style compared with freestyle (RR 1.13, 95% CI 1.03 to 1.27; P=0.011).ConclusionsAmong male and female South Korean elite wrestling athletes training for the Olympic Games, most injuries were mild and occurred in the lower extremities. Weight class influenced injury severity in both wrestling styles, and lightweight athletes had higher injury rates.

Abstract:

ABSTRACT Introduction: Although the positive effects of physical activity on global health are well documented, sports practice is associated with a greater risk of injury; in professional soccer in particular, the risk is substantial. Objective: The primary objective of this study was to investigate the incidence of injuries among male athletes competing in the regional soccer championship. The secondary objective was to determine the prevalence of injuries. Methods: In this prospective cohort study, level of evidence II, the incidence and prevalence of injuries were assessed using an adapted version of the UEFA Champions League Study questionnaire. Results: This study included 310 male athletes from ten teams, aged 26.53±4.75 years, height 180.93±6.49 cm, and weight 79.32±8.29 kg, with a 4-month follow-up. Ninety-two injuries were recorded, representing a prevalence of 29.68% injuries. The body part most frequently injured was the lower limbs (86.9%). The main types of injuries were muscle tear/strain (37.0%), sprain/ligament (19.6%), and other injuries (14.1%). The injuries were mainly caused during run/sprint (33.7%), kick (12.0%) and jumping/landing (6.5%). The incidences of injuries were 15.88±8.57, 2.04±1.09, and 3.65±1.50 injuries/1000h of exposure during matches, training, and matches/training, respectively. Time-loss over the season was between 1 and 50 days, and the severity of the injuries was as follows: light (25%), minor (22.8%), moderate (43.5%) and severe (8.7%). Conclusion: This study suggests that there is a higher incidence of injuries during matches compared to training, among male regional soccer championship players. The lower limbs are the body part most affected, with a higher prevalence of rupture/strain in the thigh region, during running/sprinting. Level of evidence II; Prospective Cohort Study .

Abstract:

Context: Meniscal injury is common among military service members. Objective: To examine the incidence and characteristics of meniscal injuries in cadets at a single military institution between 2013 and 2015. Design: Cohort study. Setting: Meniscal-injury data were collected at the Center of Rehabilitation Training, the People's Liberation Army University of Science and Technology. Patients or Other Participants: A total of 2479 cadets participating in physical activities between 2013 and 2015. Main Outcome Measure(s): Injury rates, injury proportions by body mass index, risk ratios (RRs), and injury proportion ratios were reported with 95% confidence intervals (CIs). Results: The overall incidence rate was 10.08 (95% CI = 6.84, 14.84) per 1000 person-years. A multiple-comparisons test revealed differences in the relative injury rate in overweight or obese cadets versus normal-weight cadets and underweight cadets (χ2 = 8.98, P = .01). No differences were found between injured normal-weight cadets and underweight cadets (P = .66, RR = 1.39, 95% CI = 0.32, 6.06) or between injured overweight or obese cadets and injured underweight cadets (P = .24, RR = 0.42, 95% CI = 0.09, 1.91). The absolute injury rate was higher for overweight and obese cadets compared with normal-weight cadets (P < .01, RR = 0.30, 95% CI = 0.13, 0.69). The overall proportional distribution for patterns of injury was 2:1 (medial to lateral) for meniscal injuries. Grade 2 injuries were the most common. Conclusions: The high frequency and level of severity of meniscal injuries may negatively affect the readiness and health of cadets. High body mass index was a risk factor for meniscal injury.

Abstract:

Abstract Context: Underconditioned patellar stabilizing muscles could be a predisposing factor for patellar instability. Objective: To examine the effect of 2 modes of weight training on the size of the vastus medialis obliquus (VMO), the resting position and passive mobility of the patella, and the strength of the knee extensor muscles. Design: Prospective intervention, repeated measures in 3 groups. Setting: Orthopaedic and sports sciences research laboratory. Patients or Other Participants: 48 healthy adults free from back and lower extremity injuries. Intervention(s): Participants were randomly assigned to muscle hypertrophy training, muscle strength training, or the control group. Those in the training groups pursued training 3 times per week for 8 weeks. Main Outcome Measure(s): Magnetic resonance imaging and ultrasound cross-sectional area of the VMO, patellar tilt angle on magnetic resonance imaging, instrumented passive patellar mobility, and isometric knee extension torque of the dominant leg. Results: Participants in both training groups had comparable gains in VMO size, passive patellar stability, and knee extension force, all of which were greater than for the control group (P < .05). Conclusions: Both short-term muscle hypertrophy and strength training programs can reinforce the patellar stabilizers in previously untrained volunteers.

Abstract:

Purpose:To examine relationships between physical characteristics and injuries in adult figure skaters.Methods:One hundred thirty adult figure skaters (113 women and 17 men, 43 ± 9 and 55 ± 10 y old, respectively) completed study questionnaires concerning health, height and weight, exercise habits, and injuries in the preceding year.Results:The men were older and taller and weighed more than the women (P < .05). Approximately 80% had normal body-mass index (BMI, weight [kg]/height [m]2), and the other 20% were overweight or obese based on BMI. Study participants had been skating for 12 ± 10 y (range 1 to 68 y). Most skate 4 to 5 h/wk (competitive > recreational skaters, P < .05). Although approximately 50% of competitive skaters always warm up or stretch before skating, less than 30% of the recreational skaters always do so (P < .05). Seventy-two skaters (56%) reported at least 1 injury in the preceding year. Most of the injuries were acute injuries to the lower extremity and were related to skating (76%). There were no differences in the incidence of stretching or warm-up activities or the number of hours per week spent skating in those who had incurred a skating-related injury compared with those who had not been injured (P > .05).Conclusions:The results suggest that adult skaters have training and exercise habits that might increase their risk of injury and impair athletic performance. This suggests the importance of educational programming for adult skaters designed to address injury prevention and basic exercise-training principles.

AbstractAIM: The aim of this study was to identify risk factors related to the occurrence of injuries in football players. MATERIALS AND METHODS: The study included 216 football players from 12 teams in the elite football league. Football-related injury data were collected prospectively during the 2012/2013 competitive season. At baseline the following information was collected for the players: anthropometric measurements (weight, height, BMI, subcutaneous skinfolds), playing experience, injury history, physical fitness performance test (agility run), peak oxygen uptake. The incidence, type and severity of injuries and training and game exposure times were prospectively documented for each player. RESULTS: Most of the players (n = 155, 71.7%) sustained the injures during the study period. The overall injury incidence during the regular season was 6.3 injuries per 1000 athlete-exposures (95% confidence interval, 4.31-9.67). Multivariate logistic regression analysis showed that playing experience (odds ratio [OR] = 0.44; 95% CI = 0.32-0.61, p < 0.01), age (OR = 2.05; 95% CI = 1.49-2.81, p < 0.01) and a previous injury (OR = 4.4; 95% CI = 2.14-9.07, p < 0.01) were significantly correlated to increased risk of injuries. Body mass index was not associated with risk of injury. Strains (34.19%) and sprains (25.81%) were the major injury types. Twenty-seven percent of injured players were absent from football for more than 1 month, with knee injuries (25.42%) being the most severe type. CONCLUSION: The risk factors that increase injury rates in football players were previous injury, higher age and years of playing. Future research should include adequate rehabilitation program to reduce the risk of injuries.

Abstract:

Background: Extreme conditioning programs (ECPs) are fitness training regimens relying on aerobic, plyometric, and resistance training exercises, often with high levels of intensity for a short duration of time. These programs have grown rapidly in popularity in recent years, but science describing the safety profile of these programs is lacking. Hypothesis: The rate of injury in the extreme conditioning program is greater than the injury rate of weightlifting and the majority of injuries occur to the shoulder and back. Study Design: Cross-sectional study. Level of Evidence: Level 4. Methods: This is a retrospective survey of injuries reported by athletes participating in an ECP. An injury survey was sent to 1100 members of Iron Tribe Fitness, a gym franchise with 5 locations across Birmingham, Alabama, that employs exercises consistent with an ECP in this study. An injury was defined as a physical condition resulting from ECP participation that caused the athlete to either seek medical treatment, take time off from exercising, or make modifications to his or her technique to continue. Results: A total of 247 athletes (22%) completed the survey. The majority (57%) of athletes were male (n = 139), and 94% of athletes were white (n = 227). The mean age of athletes was 38.9 years (±8.9 years). Athletes reported participation in the ECP for, on average, 3.6 hours per week (± 1.2 hours). Eighty-five athletes (34%) reported that they had sustained an injury while participating in the ECP. A total of 132 injuries were recorded, yielding an estimated incidence of 2.71 per 1000 hours. The shoulder or upper arm was the most commonly injured body site, accounting for 38 injuries (15% of athletes). Athletes with a previous shoulder injury were 8.1 times as likely to injure their shoulder in the ECP compared with athletes with healthy shoulders. The trunk, back, head, or neck (n = 29, 12%) and the leg or knee (n = 29, 12%) were the second most commonly injured sites. The injury incidence rate among athletes with <6 months of experience in the ECP was 2.5 times greater than that of more experienced athletes (≥6 months of experience). Of the 132 injuries, 23 (17%) required surgical intervention. Squat cleans, ring dips, overhead squats, and push presses were more likely to cause injury. Athletes reported that 35% of injuries were due to overexertion and 20% were due to improper technique. Conclusion: The estimated injury rate among athletes participating in this ECP was similar to the rate of injury in weightlifting and most other recreational activities. The shoulder or upper arm was the most commonly injured area, and previous shoulder injury predisposed to new shoulder injury. New athletes are at considerable risk of injury compared with more experienced athletes. Clinical Relevance: Extreme conditioning programs are growing in popularity, and there is disagreement between science and anecdotal reports from athletes, coaches, and physicians about their relative safety. This study estimates the incidence of injury in extreme conditioning programs, which appears to be similar to other weight-training programs.

Abstract:

We aimed to assess the risk of injury associated with training activities in a population of elite adolescent judo athletes, expected to represent South Korea. From 2019, we prospectively collected data on elite adolescent judo athletes at the Korean Training Center. The athletes were assessed by sports medicine doctors, and data were stratified according to sex, weight class, and injury location. We used χ2 tests to compare groups. Injury rates were expressed as Poisson rates with 95% confidence intervals. One-way analysis of variance was used to investigate the pain score and recovery time due to type of injury. The study included 240 elite adolescent judo athletes whose 617 injuries (annual average, 2.57 injuries/athlete) were recorded. When all athletes were considered, most injuries occurred in the lower extremities (39.71%), followed by the upper extremities (36.63%), trunk (16.69%), and head and neck area (6.97%). Recovery time significantly differed according to the body regions in the weight classes. The pain score and recovery time according to the type of injury were significantly different. When the pain score decreased by 1, the recovery time decreased by about 1.47 days. In all weight classes, female athletes had a higher injury rate than male athletes; both male and female athletes had different recovery time depending on their weight class. The type of injury influenced the pain score and recovery time, with pain score being associated with recovery time.

Abstract:

Body composition (BC), training volume/pattern, and injury status are a few important factors affecting training quality and sport performance in female artistic gymnastics. We aimed to examine BC status, training volume/pattern, and injury status during the first competition period. Our cross-sectional study included 17 female gymnasts (age: 17.4 ± 4.1 years, body height: 159.8 ± 6.2 cm, and body weight: 54.8 ± 5.3 kg) who were high performance at the international and national level. The BC (measured by dual-energy X-ray absorptiometry) parameters included body height and mass, body fat percentage (BF %), lean body mass (LBM), body mass index (BMI), total bone mineral density (BMD total), and total bone mineral content (BMC total). Training volume and pattern were assessed via an author-developed questionnaire, while injury status (i.e., anatomical location, symmetry and rate of injuries) was assessed via a modified questionnaire on overuse injuries used in sports injury epidemiology studies with elite-level athletes. Body composition parameters were as follows: the BMI was 21.5 ± 1.4 kg/m2, BF % was 21.9 ± 4.7%, LBM was 41.2 ± 3.4 kg, BMD total was 1.22 ± 0.08 g/cm2, and BMC total was 2486 ± 344 g. Furthermore, the average weekly volume of training was 23.5 ± 1.4 h, with the highest training volume occurring on Monday and Tuesday and high variability within gymnasts. Our study also revealed that the most frequently injured joints that had the most negative impact on training volume, sport performance and pain status were the ankles and low back, followed by the knees and shoulders. This kind of yearly screening method is warranted to allow more definitive conclusions to be made on adjusted training and preventive strategies.

Abstract:

ABSTRACT Introduction: Road running has been increasing dramatically in Brazil and worldwide for years. However, research into this practice has privileged high performance athletes while neglecting recreational runners, even though they constitute a significant majority of participants. Objectives: This study analyzed the associations between demographic and training characteristics of recreational runners in 5 km, 10 km and half marathon events, and the occurrence of musculoskeletal injuries. Methods: The study used data from 395 adult runners (229 men and 166 women, respectively aged 37.9 ± 9.5 and 37.1 ± 8.7 years, body weight 77 ± 10.5 and 61 ± 9 kg, and height 1.75 ± 0.07 m and 1.62 ± 0.07 m), who voluntarily and anonymously answered a questionnaire available on the Internet. Results: Plantar fasciitis, chondromalacia patellae (runner's knee) and tibial periostitis were the most frequently mentioned injuries in both sexes. Predisposing factors for injury (longer running time, average weekly mileage, maximum mileage and average speed in a workout) predominated in the male group, which had more types of injury and longer layoffs for this reason. Most respondents (63.3% men and 60.2% women) did not perform isolated stretching exercises; in those who did perform these exercises, and in those who stretched before and/or after training for races or competitions, there was no reduction in the incidence of injuries. Conclusion: Men showed a tendency towards greater intensity and volume of race training, in addition to longer running time, which are predisposing factors for injury. This may explain the greater number of different injuries reported in the male group, as well as the longer layoff periods.

Abstract:

Background:Partial body weight-supported treadmill training has been shown to be effective in gait training for patients with neurological disorders such as spinal cord injuries and stroke. Recent applications on children with cerebral palsy were reported, mostly on spastic cerebral palsy with single subject design. There is lack of evidence on the effectiveness of such training for nonspastic cerebral palsy, particularly those who are low functioning with limited intellectual capacity.Objectives:This study evaluated the effectiveness of partial body weight-supported treadmill training for improving gross motor skills among these clients.Study design:A two-period randomized crossover design with repeated measures.Methods:A crossover design following an A–B versus a B–A pattern was adopted. The two training periods consisted of 12-week partial body weight-supported treadmill training (Training A) and 12-week conventional gait training (Training B) with a 10-week washout in between. Ten school-age participants with nonspastic cerebral palsy and severe mental retardation were recruited. The Gross Motor Function Measure-66 was administered immediately before and after each training period.Results:Significant improvements in dimensions D and E of the Gross Motor Function Measure-66 and the Gross Motor Ability Estimator were obtained.Conclusions:Our findings revealed that the partial body weight-supported treadmill training was effective in improving gross motor skills for low-functioning children and adolescents with nonspastic cerebral palsy.Clinical relevanceOur preliminary findings demonstrated that partial body weight-supported treadmill training was a treatment of choice for improving gross motor functioning related to standing and ambulation for low-functioning children and adolescents with nonspastic cerebral palsy and limited intellectual capacity.

Abstract:

Introduction. Martial arts, including MMA and Muay Thai are considered to be high-risk disciplines due to the nature and specificity of the sports activity undertaken. The objective of the study was to evaluate the incidence of limb injuries in martial arts using the example of MMA and Muay Thai. Material and research method. The study covered a group of 66 individuals, including 38 (57.6%) MMA athletes and 28 (42.4%) Muay Thai practitioners. It was carried out in one of Krakow's martial arts clubs in 2016, based on a self-constructed survey questionnaire. The results were subjected to statistical analysis using the Microsoft Excel 2010 spreadsheet and the Statistica software version 10.0 PL. Results. Among the persons surveyed, 67% suffered an upper and/or lower limb injury. Injuries occurred both among the athletes with short training experience (1-3 years) and those who have trained for a longer period of time. The athletes with the shortest training experience (1- 3 years) were statistically more likely to suffer an injury. The number of injuries was significantly higher among Muay Thai athletes. The incidence of injuries was not significantly lower among the individuals who used protective equipment during training, or among recreational athletes. Injuries were more common among the individuals who trained with a sparring partner, including 24 MMA fighters (70.6%), and 10 Muay Thai athletes (55.5%). Conclusions. 1. Upper and lower limb injuries are a common problem among martial arts practitioners, especially among MMA athletes. 2. The athletes' weight category and age do not have any effect on the incidence of injuries among MMA and Muay Thai practitioners. 3. Injuries are considerably more common during contact exercises, both in MMA and in Muay Thai. 4. The incidence of injuries is equally high among the individuals who participate in sports competitions and in amateur athletes.

Abstract:

Background: Musculoskeletal injuries are prevalent among military trainees and certain occupations. Fitness and body mass index (BMI) have been associated with musculoskeletal conditions, including stress fractures. Hypothesis: The incidence of, and excess health care utilization for, stress fracture and non–stress fracture overuse musculoskeletal injuries during the first 6 months of service is higher among unfit female recruits. Those who exceeded body fat limits are at a greater risk of incident stress fractures, injuries, or health care utilization compared with weight-qualified recruits. Study Design: Cohort study; Level of evidence, 3. Methods: All applicants to the United States Army were required to take a preaccession fitness test during the study period (February 2005–September 2006). The test included a 5-minute step test scored as pass or fail. BMI was recorded at application. There were 2 distinct comparisons made in this study: (1) between weight-qualified physically fit and unfit women and (2) between weight-qualified physically fit women and those who exceeded body fat limits. We compared the incidence of, and excess health care utilization for, musculoskeletal injuries, including stress fractures and physical therapy visits, during the first 183 days of military service. Results: Among the weight-qualified women, unfit participants had a higher non–stress fracture injury incidence and related excess health care utilization rate compared with fit women, with rate ratios of 1.32 (95% CI, 1.14-1.53) and 1.18 (95% CI, 1.10-1.27), respectively. Among fit women, compared with the weight-qualified participants, those exceeding body fat limits had higher rate ratios for non–stress fracture injury incidence and related excess health care utilization of 1.27 (95% CI, 1.07-1.50) and 1.20 (95% CI, 1.11-1.31), respectively. Weight-qualified women who were unfit had a higher incidence of stress fractures and related excess health care utilization compared with fit women, with rate ratios of 1.62 (95% CI, 1.19-2.21) and 1.22 (95% CI, 1.10-1.36), respectively. Among fit women exceeding body fat limits, the stress fracture incidence and related excess health care utilization rate ratios were 0.79 (95% CI, 0.49-1.28) and 1.44 (95% CI, 1.20-1.72), respectively, compared with those who were weight qualified. Conclusion: The results indicate a significantly increased risk of musculoskeletal injuries, including stress fractures, among unfit recruits and an increased risk of non–stress fracture musculoskeletal injuries among recruits who exceeded body fat limits. Once injured, female recruits who were weight qualified but unfit and those who were fit but exceeded body fat limits had increased health care utilization. These findings may have implications for military accession and training policies as downsizing of military services will make it more important than ever to optimize the health and performance of individual service members.

Abstract:

Context: Strength training in children, in combination with plyometric and/or agility training, has become an increasingly popular tactic for athletes to gain a competitive edge during the off-season. The present review clarifies some common myths associated with strength training in children, and it outlines the most current recommendations. Evidence Acquisition: Relevant studies on strength training in children and adolescents were reviewed (search results included studies indexed in PubMed and MEDLINE from 1980 through 2008). Also reviewed were recommendations from consensus guidelines and position statements applicable to strength training in youth. Results: Children can improve strength by 30% to 50% after just 8 to 12 weeks of a well-designed strength training program. Youth need to continue to train at least 2 times per week to maintain strength. The case reports of injuries related to strength training, including epiphyseal plate fractures and lower back injuries, are primarily attributed to the misuse of equipment, inappropriate weight, improper technique, or lack of qualified adult supervision. Conclusion: Youth—athletes and nonathletes alike—can successfully and safely improve their strength and overall health by participating in a well-supervised program. Trained fitness professionals play an essential role in ensuring proper technique, form, progression of exercises, and safety in this age group.

Abstract:

Soldiers are often required to carry heavy loads that can exceed 45 kg. The physiological costs and biomechanical responses to these loads, whilst varying with the contexts in which they are carried, have led to soldier injuries. These injuries can range from musculoskeletal injuries (e.g., joint/ligamentous injuries and stress fractures) to neurological injuries (e.g., paresthesias), and impact on both the soldier and the army in which they serve. Following treatment to facilitate initial recovery from injuries, soldiers must be progressively reconditioned for load carriage. Optimal conditioning and reconditioning practices include load carriage sessions with a frequency of one session every 10–14 days in conjunction with a program of both resistance and aerobic training. Speed of march and grade and type of terrain covered are factors that can be adjusted to manipulate load carriage intensity, limiting the need to adjust load weight alone. Factors external to the load carriage program, such as other military duties, can also impart physical loading and must be considered as part of any load carriage conditioning/reconditioning program.

Abstract:

‘Cabernet franc’ grapevines (Vitis vinifera) sustained severe winter injuries of all aboveground parts following two consecutive freezing events in 2014 and 2015 in Ohio. To ensure grapevine recovery, adjustment of pruning and training practices must be accomplished. However, optimum training of new shoots for trunk replacement was not known and research-based information on this topic was lacking. Therefore, the purpose of this study was to evaluate different training and pruning methods for trunk renewal and recovery of ‘Cabernet franc’ and their impacts on growth, yield, cropload, and fruit composition following severe winter injuries. In 2016, grapevines were manipulated using a combination of training [Fan, vertical shoot positioning (VSP), or both], pruning (cane- or spur-pruned), and trunks (two, four, or more trunks per vine). The Fan system took less time to train than VSP during the growing season; however, the latter took less time to train and prune during the following dormant season. Training and pruning methods with increased buds per vine resulted in increased shoots, leaf area, pruning weight, clusters, and yield per vine but decreased juice total soluble solids (TSS). The exceptions were vines with combined training systems of Fan and VSP, in which leaf areas and pruning weights were reduced despite increased bud count per vine after pruning. In conclusion, each system has advantages and disadvantages; however, the Fan training system with cane pruning and multiple trunks produced the most optimum trunk size, yield, cropload, and fruit composition. Therefore, following trunk freeze injury, we recommend retaining all shoots using the Fan training during the growing season. During the subsequent dormant season, growers should select medium-sized canes for trunk replacement and train four trunks and four canes for the VSP system.

Abstract:

IntroductionRunning injuries affect millions of persons every year and have become a substantial public health issue owing to the popularity of running. To ensure adherence to running, it is important to prevent injuries and to have an in-depth understanding of the aetiology of running injuries. The main purpose of the present paper was to describe the design of a future prospective cohort study exploring if a dose–response relationship exists between changes in training load and running injury occurrence, and how this association is modified by other variables.Methods and analysisIn this protocol, the design of an 18-month observational prospective cohort study is described that will include a minimum of 20 000 consenting runners who upload their running data to Garmin Connect and volunteer to be a part of the study. The primary outcome is running-related injuries categorised into the following states: (1) no injury; (2) a problem; and (3) injury. The primary exposure is change in training load (eg, running distance and the cumulative training load based on the number of strides, ground contact time, vertical oscillation and body weight). The change in training load is a time-dependent exposure in the sense that progression or regression can change many times during follow-up. Effect-measure modifiers include, but is not limited to, other types of sports activity, activity of daily living and demographics, and are assessed through questionnaires and/or by Garmin devices.Ethics and disseminationThe study design, procedures and informed consent have been evaluated by the Ethics Committee of the Central Denmark Region (Request number: 227/2016 – Record number: 1-10-72-189-16).

Abstract:

Injuries resulting from exiting trucks represent a substantial cost to businesses who operate these equipment. Many vehicles have aids to assist the driver in safely entering/exiting the vehicle. Nevertheless, many drivers do not use these aids. The purpose of this study was to quantify impact forces experienced during various truck exit methods. The study investigated impact forces of ten male subjects while exiting two tractors and a step-van. The results showed that jumping from cab-level resulted in impact forces as high as 12 times subject body weight; whereas, fully utilizing the steps and grab-rails kept the impact forces under two times body weight. Using the grab-rail during exiting the step-van resulted in over 40% reduction in impact force. An approach that emphasizes optimal design of entry/exit aids, coupled with driver training of proper use of these aids and education on the potential risks is expected to minimize vehicle-related musculoskeletal injuries.

Abstract:

Objective. To investigate the effects of sitting Tai Chi on muscle strength, balance control, and quality of life (QOL) among survivors with spinal cord injuries (SCI).Methods. Eleven SCI survivors participated in the sitting Tai Chi training (90 minutes/session, 2 times/week for 12 weeks) and eight SCI survivors acted as controls. Dynamic sitting balance was evaluated using limits of stability test and a sequential weight shifting test in sitting. Handgrip strength was also tested using a hand-held dynamometer. QOL was measured using the World Health Organization’s Quality of Life Scale.Results. Tai Chi practitioners achieved significant improvements in their reaction time (P=0.042); maximum excursion (P=0.016); and directional control (P=0.025) in the limits of stability test after training. In the sequential weight shifting test, they significantly improved their total time to sequentially hit the 12 targets (P=0.035). Significant improvement in handgrip strength was also found among the Tai Chi practitioners (P=0.049). However, no significant within and between-group differences were found in the QOL outcomes (P>0.05).Conclusions. Twelve weeks of sitting Tai Chi training could improve the dynamic sitting balance and handgrip strength, but not QOL, of the SCI survivors.

Abstract:

Abstract Introduction Injuries are the major cause of morbidity and loss of active training days in military populations. Previous investigations have mainly focused on lower extremities. This study evaluated the incidence, diagnosis, and risk factors of upper extremity injuries requiring hospitalization in a large cohort of Finnish conscripts during a 5-year period. Materials and Methods A total of 128,714 male military conscripts, who served 6–12 months in compulsory military service, were studied. Injury hospitalization data were obtained from the National Hospital Discharge Register. The main outcome variables were hospitalization due to any injuries to the upper extremity and hospitalization due to traumatic shoulder dislocation. Background variables for risk factor analysis included length of military service, age, body height and weight, body mass index, and physical fitness. Results Overall person-based incidence rate for hospitalization due to upper extremity injury was 743 (95% confidence interval [CI]: 697–791) per 100,000 conscripts per year. Shoulder joint dislocation was the most common injury: incidence rate of 103 (95% CI: 86–122) per 100,000 conscripts per year. Trend during follow-up years 1998–2002 was decreasing concerning on any upper extremity injuries (odd ratios [OR] 0.90; 95% CI: 0.86–0.95, P < 0.001). Body mass index > 25 increased a risk for any injuries of the upper extremity (OR 1.29; CI 95%: 1.10–1.51) and, especially, for shoulder joint dislocation (OR 1.88; CI 95%: 1.26–2.80). Conclusions Overweight young men were at greater risk for upper extremity injuries. The incidence rate of traumatic shoulder joint dislocation was considerably higher than reported previously. In conclusion, preventive measures such as reducing the body weight of overweight young men should play an important role in reducing the incidence of upper extremity injuries.

Abstract:

El propósito de este estudio fue determinar aquellos factores de riesgo que pueden causar lesiones en corredores, tanto en el vientre muscular, como tendinosas. Veintiséis atletas de ambos sexos de la comunidad autónoma de Galicia realizaron diferentes test de flexibilidad y longitud del miembro inferior, del ángulo Q de la rodilla y de la fuerza explosiva. Además se analizó la información de los factores asociados al entrenamiento, como los kilómetros y las sesiones semanales, nivel competitivo del atleta, tipo de zapatillas que usa predominantemente en los entrenamientos, superficie en la que suele entrenar, lesiones durante el último año, si usaban plantillas, especialidad atlética que practicaban, edad, peso y talla. Durante las siguientes 12 semanas, los corredores siguieron entrenando como venían haciendo habitualmente y se registraron todas las lesiones que sucedieron en ese periodo.Después de esto, utilizando regresión lineal, obtuvimos diferentes modelos que explicaban la variabilidad de lesiones en general, y particularmente las del vientre muscular y de los tendones. Encontramos que variables como el volumen de entrenamiento y las lesiones previas se correlacionan positivamente con la variable dependiente «lesiones en 12 semanas», y que además el material sintético de las pistas de atletismo, el aumento del ángulo Q y la edad, provocan lesiones del vientre muscular y del tendón respectivamente.Palabra clave: Lesiones del corredor, tendinopatías, lesiones por sobrecarga, esguinces, daño muscular.Abstract: The purpose of this study was to determine those risk factors that may cause running injuries in general, and particularly damage to the muscle mass, and the tendon. Twenty six male and female Galician runners were evaluated about their lower limb flexibility and length, knee Q angle, explosive power and training features such as kilometers and sessions per week, level of competition, shoes, surface, injuries last year, use of insoles, athletic specially, age, weight and height. During next 12 weeks runners continued training as they had been doing regularly and we recorded all injuries that appeared in this period. After that and from the liner regression we obtained different models that explained the variability of general injuries, tendon injuries and damages to the muscle mass. We also find positive correlations between previous injuries and training volume, and these with the dependent variable «injuries in 12 weeks». In regard to tendinopathy and muscle mass injuries, we observed that the synthetic material present in the track is a risk factor for these muscle injuries. Meanwhile, the increasing age and the Q angle, increments the occurrence of tendon injuries.Key words: Running injuries, tendinopathies, overuse injuries, strains, muscle damage.

Abstract:

Karate training, despite the many positive health benefits, carries a risk of injury for participants. The current cross-sectional study aimed to investigate knee injury profiles among Iranian elite karatekas. Participants who attended the national team qualifiers, which included 390 male Kumite karatekas (age 24 ± 3 years old and weight 63 ± 12 kg), participated in this study. Information on knee injuries (injury history, type of injury mechanisms, and effects of knee symptoms on the ability to perform daily activities and recreational activities) were obtained using the Knee Outcome Survey (KOS). Using Pearson’s correlation coefficient, the study examined the relationships between different variables, including KOS subscales and levels of self-reported knee joint function. Our findings indicated that 287 karatekas (73.6%) experienced knee injuries. The anterior cruciate ligament (ACL) rupture (6.9%), articular cartilage (5.4%), and meniscus damage (3.8%) were the main typology of injury. In addition, there were no differences in knee injuries between the non-dominant and dominant legs. Most injuries occurred during the preparatory period (n = 162, 50%), especially during training periods. The KOS subscales scores (Mean ± Sd) for activities of daily living (ADL) and sports activity (SAS) were, respectively, 89 ± 11 and 91 ± 9. The self-reported scores for both the ADL and SAS subscales were, respectively, 89 ± 11 and 90 ± 10. Pearson coefficients of ADL and SAS subscales with their self-reported score were r = 0.761 (p < 0.0001) and r = 0.782 and (p < 0.0001), respectively. The profile of knee injuries in the current investigation is similar to previous surveys that reported lower extremity injury patterns. The findings of this study could be adopted to inform practice aimed at planning interventions for the reduction and prevention of knee injuries among karatekas.
