Injuries and Rapid Weight Loss in Elite Adolescent Taekwondo Athletes: A Korean Prospective Cohort Study

Abstract

Objectives To report injury patterns associated with training activities of elite adolescent Taekwondo athletes who are expected to represent South Korea in the future. Methods Beginning in 2019, we prospectively collected data on elite adolescent Taekwondo athletes at the Korean Training Center. The athletes were assessed by sports medicine doctors, and data were stratified according to sex, weight class, injury location, injuries during the weight loss period, and weight loss method. We used χ2 tests were used to compare groups. Injury rates were expressed as Poisson rates with 95% confidence intervals. Results There were 117 male and 102 female elite adolescent Taekwondo athletes. The mean weight loss among athletes was 3.37 (±1.23) kg, and the mean duration of weight loss was 7.53 (±3.40) days. In general, all athletes used similar weight loss methods. We recorded 846 injuries (annual average, 3.98 injuries/athlete). In general, female athletes had higher injury rates than their male counterparts. Additionally, the athletes had significantly higher injury rates during weight loss periods than during other periods of training. When all athletes were considered, most injuries occurred in the lower extremities (63.2%), followed by the trunk (14.2%), upper extremities (16.3%), and the head and neck area (6.3%). The injury severity significantly influenced the body regions in weight categories. Conclusion Rapid weight loss is related to the incidence of sports damage in athletes. Most injuries occur during weight loss periods in South Korean elite adolescent Taekwondo athletes. Moreover, the injury rate and injury severity depends on weight class.

Epidemiology of Sports Injuries in Korean Elite Female Fencing Athletes: A Prospective Cohort Study

“…It is most likely because athletes use a variety of skills during training and not all training hours are used for open combat. 17 Further research is needed to assess specific injury patterns during competition and training, taking into account the diversity of reported injury areas and mechanisms. This information is useful for establishing an injury prevention strategy based on specific circumstances of elite athletes.…”

Epidemiologia Das Lesões Esportivas Em Atletas Coreanas De Esgrima De Elite: Um Estudo Prospectivo De Coorte

“…Isso é mais provável porque os atletas usam diversas habilidades durante o treinamento e nem tudo o que é treinado é usado no combate aberto. 17 Mais pesquisas são necessárias para avaliar padrões específicos de lesão durante a competição e treinamento, levando em conta a diversidade de áreas e mecanismos de lesão. Essas informações são úteis para estabelecer uma estratégia de prevenção de lesões com base em circunstâncias específicas das atletas de elite.…”

The Practice of Weight Loss in Combat Sports Athletes: A Systematic Review

“…In 2010, Artioli et al established a rapid WL questionnaire (RWLQ) and tested its reliability and validity [33]. Since then, most of the studies surveying the WL practices of CS athletes have adapted this questionnaire [2][3][4][5][6][7]12,13,[15][16][17][18][19][20][34][35][36][37][38][39][40][41][42][43][44][45][46]. Although some studies have further explored other fields (e.g., physiological symptoms, psychological symptoms, perceived influence, and injury rate) [36,37,41], the original content of the survey is always applicable.…”

Although some studies have further explored other fields (e.g., physiological symptoms, psychological symptoms, perceived influence, and injury rate) [36,37,41], the original content of the survey is always applicable. Specifically, each study involved CS athletes' demographic information, competition performance information, weight history, WL methods, and person(s) who influence their WL practice(s).…”
