[Ab] Resumo:INTRODUCTION: The objective was to report epidemiological and lesional features among children practicing wrestling as a game in Dakar, Senegal. METHODS: It was a retrospective study including all patients under 16, victims of wrestling game injuries. We studied epidemiological and lesional aspects in children: frequency of wrestling game injuries among all games, age, sex, geographic origin, place of injury, parent's socioeconomic status, nature of the injury and location. RESULTS: Wrestling game injuries represented 19.9% injuries in all games. Sex-ratio was 33.4. The most affected age group was the 6-10 years old age group. The majority of children are from suburban Dakar (64%). Injuries occurred most often at home and in the street. Most children are from low socioeconomic status (64%). Fractures predominated and were localized almost exclusively on the elbow. CONCLUSION: Wrestling game injuries in Dakar occur among older children from the suburbs, living in the neighborhood of great wrestling champions' districts of residence. Wrestling game cause injuries, consisting mostly of elbow fractures.

[Ab] Resumo:CONTEXT: Few researchers have described the incidence of the most severe injuries sustained by student-athletes at the collegiate level. OBJECTIVE: To describe the epidemiology of severe injuries within 25 National Collegiate Athletic Association (NCAA) sports in the 2009-2010 through 2014-2015 academic years. DESIGN: Descriptive epidemiology study. SETTING: Aggregate injury and exposure data from 25 NCAA sports. PATIENTS OR OTHER PARTICIPANTS: Collegiate student-athletes in the 2009-2010 through 2014-2015 academic years. MAIN OUTCOME MEASURE(S): Injury data from the NCAA Injury Surveillance Program were analyzed. A severe injury (1) occurred during a sanctioned competition or practice, (2) required medical attention by an athletic trainer or physician, and (3) resulted in at least 21 days lost from sport activity or a premature end to the sport season. Injury counts, proportions, rates per 1000 athlete-exposures (AEs), rate ratios (RRs), and injury proportion ratios were reported with 95% confidence intervals (CIs). RESULTS: A total of 3183 severe injuries were reported, for an injury rate of 0.66/1000 AEs. Wrestling had the highest severe injury rate (1.73/1000 AEs), followed by women's gymnastics (1.40/1000 AEs) and football (0.97/1000 AEs). Overall, the severe injury rate was higher in competition than in practice (RR = 4.25, 95% CI = 3.97, 4.56). Most severe injuries were reported during the regular season (69.3%, n = 2206); however, severe injury rates did not differ between the preseason and regular season (RR = 0.98, 95% CI = 0.91, 1.06). Common severely injured body parts were the knee (32.9%, n = 1047), lower leg/ankle/foot (22.5%, n = 715), and head/face/neck (11.2%, n = 358). Common severe injury diagnoses were sprains (32.9%, n = 1048), strains (16.9%, n = 538), and fractures (14.4%, n = 458). Common severe injury mechanisms were player contact (39.3%, n = 1251), noncontact (25.1%, n = 800), and surface contact (12.0%, n = 383). CONCLUSIONS: Severe injuries occurred across many sports and by numerous mechanisms. By identifying these sport-specific patterns, clinicians' efforts can be tailored toward improving injury-prevention strategies and health outcomes.

[Ab] Resumo:CONTEXT: At the request of the National Wrestling Coaches Association and the head wrestling coach at our university, we conducted a study of infection transmission in collegiate wrestlers. OBJECTIVE: To examine disinfectant effectiveness and develop best-practice guidelines for minimizing the spread of skin infections via wrestling mats. DESIGN: Controlled laboratory study and crossover study. SETTING: Laboratory and two 15-college wrestling invitational meets. PATIENTS OR OTHER PARTICIPANTS: A total of 231 collegiate wrestlers and 8 officials. INTERVENTION(S): In the laboratory-based part of the study, we measured the bacterial load of mats disinfected with 10% bleach, OxiTitan, Benefect, eWater, and KenClean and inoculated with Staphylococcus epidermidis (strain ATCC 12228) at a concentration of 6.5 × 10 bacteria/cm . In the empirical part of the study, we used these disinfectants during 2 invitational meets and measured mat and participant bacterial load during competition. Participants were swabbed at weigh-in and after their last bout. Mat bacterial load was monitored hourly. MAIN OUTCOME MEASURE(S): We determined total colony counts and species. RESULTS: With controlled testing, we observed that products claiming to have residual activity reduced bacterial load by 63% over the course of competition compared with nonresidual agents. Only 4 of 182 participating wrestlers tested positive for methicillin-resistant Staphylococcus aureus , which is the normal population occurrence. The predominant species on mats were skin bacteria ( Staphylococcus epidermidis ) and substantial levels of respiratory bacteria ( Streptococcus pneumoniae ), as well as several soil species and a surprisingly low incidence of fecal bacteria ( Escherichia coli ). Disinfectant effectiveness during the meets was consistent with controlled study findings. Cleaning mats with residual disinfectants reduced the average bacterial load by 76% compared with nonresidual cleaners. Using a footbath did not reduce the bacterial load compared with a bleach-cleaned mat, but using alcohol-based hand gel reduced it by 78%. CONCLUSIONS: Best practices based on these data include backward mopping of the mats with a residual disinfectant pulled behind the cleaner, allowing mats to dry before walking on them, having wrestlers use hand gel before each bout, and strongly recommending that all wrestlers receive annual influenza vaccinations.

[Ab] Resumo:Chaabene, H, Negra, Y, Bouguezzi, R, Mkaouer, B, Franchini, E, Julio, U, and Hachana, Y. Physical and physiological profile of wrestler athletes: a short review. J Strength Cond Res 31(5): 1411-1442, 2017-Wrestling is one of the oldest combat sports, disputed since the ancient Greek Olympic Games. This combat sport discipline has caught the attention of scientists since 1943 which is the date that matches the appearance of the first scientific research dealing with wrestling. The current short review aimed to summarize and critically analyze the scientific literature related to wrestling's physical and physiological attributes and to provide practical recommendations for testing/training together with new perspective and areas of future scientific research. Regardless of sex and wrestling styles, an optimal level of cardiorespiratory fitness is important to help sustaining effort throughout the duration of the match and to stimulate the recovery process between periods. With regard to the anaerobic power and capacity, the available studies were in agreement about their critical importance toward reaching high-level wrestling success since these variables have discriminated well between successful and less-successful wrestlers regardless of age, weight classes, and wrestling styles. Physical fitness parameters such as maximal dynamic strength, isometric strength, explosive strength, and strength endurance are closely related to high-level wrestling performance. However, flexibility level seems not to be one of the key fitness variables that help to reach high-level wrestling success. Overall, to achieve high-level wrestling performance, training should be directed to develop anaerobic power and capacity, aerobic power, maximal dynamic and isometric strength, explosive strength, and strength endurance.

[Ab] Resumo:OBJECTIVE: To assess whether athletes who played American varsity high school football between 1956 and 1970 have an increased risk of neurodegenerative diseases later in life. PATIENTS AND METHODS: We identified all male varsity football players between 1956 and 1970 in the public high schools of Rochester, Minnesota, and non-football-playing male varsity swimmers, wrestlers, and basketball players. Using the medical records linkage system of the Rochester Epidemiology Project, we ascertained the incidence of late-life neurodegenerative diseases: dementia, parkinsonism, and amyotrophic lateral sclerosis. We also recorded medical record-documented head trauma during high school years. RESULTS: We identified 296 varsity football players and 190 athletes engaging in other sports. Football players had an increased risk of medically documented head trauma, especially if they played football for more than 1 year. Compared with nonfootball athletes, football players did not have an increased risk of neurodegenerative disease overall or of the individual conditions of dementia, parkinsonism, and amyotrophic lateral sclerosis. CONCLUSION: In this community-based study, varsity high school football players from 1956 to 1970 did not have an increased risk of neurodegenerative diseases compared with athletes engaged in other varsity sports. This was from an era when there was a generally nihilistic view of concussion dangers, less protective equipment, and no prohibition of spearing (head-first tackling). However, the size and strength of players from previous eras may not be comparable with that of current high school athletes.

[Ab] Resumo:The purpose of this study was to investigate the effects of the T1470A polymorphism (rs1049434) on power-oriented performance and lactate concentration during or after cycling sprints in Japanese wrestlers. Participants (199 wrestlers and 649 controls) were genotyped for the T1470A genotype (rs1049434) using the TaqMan Assay. All wrestlers were international (n=77) or national (n=122) level athletes. Among them, 46 wrestlers performed 2 anaerobic performance tests, a 30-s Wingate Anaerobic test (WAnT) and a series of 10 maximal effort 10-s sprints on a cycle ergometer. Blood lactate levels were measured before, during, and after the tests. In the A-allele recessive model (AA vs. TA+TT), the frequency of the AA genotype was significantly higher in all wrestlers than in controls (p=0.037). Wrestlers with AA genotype had lower blood lactate concentrations than those with TA+TT genotype at 10 min after the WAnT and following the 5 and the final set of repeated cycling sprints (p<0.05). The AA genotype of the T1470A polymorphism is over-represented in wrestlers compared with controls and is associated with lower blood lactate concentrations after 30-s WAnT and during intermittent sprint tests in Japanese wrestlers.

[Ab] Resumo:OBJECTIVE: Describe chest and abdominal injury epidemiology among US high school athletes. DESIGN: Retrospective analysis of longitudinal surveillance data. SETTING: Injury data from 2005/06 to 2013/14 academic years were collected using an internet-based surveillance system. PARTICIPANTS: A large sample of US high schools. ASSESSMENT OF RISK FACTORS: Injuries sustained as a function of sport. MAIN OUTCOME MEASURES: Chest, rib, thoracic spine, and abdominal injuries sustained during high school athletic events. RESULTS: Overall 1487 chest, rib, thoracic spine, and abdominal injuries occurred during 30 415 179 athletic exposures (AEs); an injury rate of 4.9 injuries per 100 000 AEs. Over half (56.8%) of injured athletes were evaluated by another medical provider in addition to the athletic trainer, and 34 injuries (2.3%) required surgery. Diagnostic techniques, including x-ray, magnetic resonance imaging or computed tomography were used in 729 (49.0%) injuries. The injury rate was higher in boys' (6.8) than girls' (2.0) sports [rate ratio (RR), 3.43; 95% CI, 3.04-4.10]. Football (47.7%) accounted for the highest proportion of injuries followed by wrestling (18.5%), boys' soccer (4.6%), and girls' soccer (3.7%). The rate of injury was higher in competition than practice, (RR, 2.86; 95% CI, 2.59-3.23). Only 57.7% of injured athletes were able to return to play within 1 week. CONCLUSIONS: Chest and abdominal injuries in high school sports although relatively rare, can result in loss of playing time and frequently prompt medical evaluation. Thus, they present a physical and economic burden. To optimize prevention, further studies can focus on subgroup risk factor identification to drive development of targeted prevention strategies.

[Ab] Resumo:BACKGROUND: The effect of rapid weight loss program on adipocytokines is not yet clear. Therefore the aim of the present study was the effect of rapid weight loss (4%) on leptin, adiponectin, and insulin resistance in elite free style wrestlers. METHODS: For this purpose, fifteen young freestyle wrestlers (weight 67.6±0.8, BMI 22.5±0.21 kg/m², body fat percent 6.12±0.18, waist to hip circumference ratio 0.82±0.08) in two weight categories (60 and 66 kg) were randomly selected. Caloric intake (mean 7 days measured by Food analyzer software) measured at 1 week before weight loss program by standard methods. Wrestlers performed a week rapid weight loss (average of 4% of body weight loss) protocol by caloric and water restriction by 60% (600-700 kcal per day), under the supervision of their coach. Anthropometric characteristics, leptin, adiponectin and insulin resistance were measured before and 12 and 36 hours after rapid weight loss program. RESULTS: Rapid weight loss program with 4% of weight loss had a significantly reduced impact on anthropometric factors; leptin level, insulin resistance, and increased beta cell function, while the changes of adiponectin were not significant after rapid weight loss. CONCLUSIONS: Findings of this study shows that rapid weight loss program significantly decreased leptin, L/A ratio and HOMA-IR, without significant changes on adiponectin levels. These changes may have harmful physiological effects on wrestlers' bodies but they can be useful to regulate of fatty acid, glucose metabolism, and insulin resistance.

[Ab] Resumo:It is common for athletes in weight-category sports to try to gain a theoretical advantage by competing in weight divisions that are lower than their day-to-day body mass (BM). Weight loss is achieved not only through chronic strategies (body-fat losses) but also through acute manipulations before weigh-in ("making weight"). Both have performance implications. This review focuses on Olympic combat sports, noting that the varied nature of regulations surrounding the weigh-in procedures, weight requirements, and recovery opportunities in these sports provide opportunity for a wider discussion of factors that can be applied to other weight-category sports. The authors summarize previous literature that has examined the performance effects of weightmaking practices before investigating the physiological nature of these BM losses. Practical recommendations in the form of a decision tree are provided to guide the achievement of acute BM loss while minimizing performance decrements.

[Ab] Resumo:CONTEXT: Injury rates compare the relative frequency of sport-related concussions across groups. However, they may not be intuitive to policy makers, parents, or coaches in understanding the likelihood of concussion. OBJECTIVE: To describe 4 measures of incidence (athlete-based rate, athlete-based risk, team-based rate, and team-based risk) during the 2011-2012 through 2014-2015 academic years. DESIGN: Descriptive epidemiology study. SETTING: Aggregate injury and exposure data collected from the National Collegiate Athletic Association Injury Surveillance Program in 13 sports (men's baseball, basketball, football, ice hockey, lacrosse, soccer, and wrestling and women's basketball, ice hockey, lacrosse, soccer, softball, and volleyball). PATIENTS OR OTHER PARTICIPANTS: Collegiate student-athletes. MAIN OUTCOME MEASURE(S): Sport-related concussion data from the National Collegiate Athletic Association Injury Surveillance Program during the 2011-2012 through 2014-2015 academic years were analyzed. We calculated concussion rates per 1000 athlete-exposures (AEs), concussion risk, average number of concussions per team, and percentage of teams with at least 1 concussion. RESULTS: During the 2011-2012 through 2014-2015 academic years, 1485 concussions were sustained by 1410 student-athletes across 13 sports. Concussion rates ranged from 0.09/1000 AEs in men's baseball to 0.89/1000 AEs in men's wrestling. Concussion risk ranged from 0.74% in men's baseball to 7.92% in men's wrestling. The average ± SD number of concussions per team ranged from 0.25 ± 0.43 in men's baseball to 5.63 ± 5.36 in men's football. The percentage of teams with a concussion ranged from 24.5% in men's baseball to 80.6% in men's football. CONCLUSIONS: Although men's wrestling had a higher concussion rate and risk, men's football had the largest average number of concussions per team and the largest percentage of teams with at least 1 concussion. The risk of concussion, average number of concussions per team, and percentage of teams with concussions may be more intuitive measures of incidence for decision makers. Calculating these additional measures is feasible within existing injury surveillance programs, and this method can be applied to other injury types.
