Taekwondo is a martial art and a combat Olympic sport. Similar to other types of combat sports, Taekwondo fights are conducted between opponents grouped by sex, age and weight classes. Disordered eating behaviors are common in combat sports with weight classes, attributed to the athletes' need to remain within a specific weight range. Pre-competition rapid weight loss (RWL) is also common, and entails a health risk.
To assess the eating attitudes and the prevalence and techniques of RWL among young Taekwondo fighters.
A total of 112 competitive Taekwondo fighters in national championships and regional competitions aged 12-21.5 years completed questionnaires pertaining to eating attitudes (EAT-26) and RWL techniques.
A total of 38% of the respondents reported precompetition RWL, with no significant between-sex difference. Common practices were training harder and eating less, but several potentially dangerous techniques were also described. Findings showed that: 70% of those reporting RWL were not assisted by another person, and the degree of RWL reached -5.5kg; 23%-40% of participants reporting RWL felt an improvement in some physical measure, yet 16% reported a decrease in subjective sport performance; 2.7% had abnormal scores on the EAT-26 questionnaire.
There is a high rate of pre-competition RWL in young Taekwondo fighters, even in lower levels of competition. Most athletes performing RWL were unassisted, and some utilized potentially dangerous techniques. Most athletes did not feel that RWL affected their sport performance, yet a significant proportion felt decreased levels of performance. Weight-class athletes should be consulted by personnel trained in sports nutrition, in both training and competition states.
跆拳道是一项武术运动,也是奥运会的格斗项目。与其他格斗运动类似,跆拳道比赛在按性别、年龄和体重级别分组的对手之间进行。在有体重级别的格斗运动中,饮食失调行为很常见,这归因于运动员需要保持在特定体重范围内。赛前快速减重(RWL)也很常见,且存在健康风险。
评估年轻跆拳道运动员的饮食态度以及赛前快速减重的发生率和方法。
共有112名年龄在12至21.5岁之间、参加全国锦标赛和地区比赛的竞技跆拳道运动员完成了有关饮食态度(EAT - 26)和赛前快速减重方法的问卷调查。
共有38%的受访者表示有赛前快速减重行为,男女之间无显著差异。常见的做法是加大训练强度和减少饮食,但也描述了一些潜在危险的方法。研究结果表明:报告有赛前快速减重行为的人中有70%没有他人协助,快速减重程度达到 - 5.5千克;报告有赛前快速减重行为的参与者中有23% - 40%感觉某些身体指标有所改善,但16%的人表示主观运动表现下降;2.7%的人在EAT - 26问卷上得分异常。
年轻跆拳道运动员赛前快速减重的发生率很高,即使在较低水平的比赛中也是如此。大多数进行赛前快速减重的运动员没有他人协助,有些人采用了潜在危险的方法。大多数运动员不认为赛前快速减重会影响他们的运动表现,但有相当一部分人感觉运动表现下降。在训练和比赛期间,应让受过运动营养培训的人员为有体重级别要求的运动员提供咨询。
