The purpose of this study was to investigate the impact of weight loss practices on nutritional status, bone health, and injury history among Korean professional jockeys.
Forty-three male jockeys completed a questionnaire to assess their weight loss practices. Of these, 10 jockeys were selected for in-depth assessment of their nutritional status, bone health, and injury history.
The questionnaires revealed that 81.4% of jockeys lost weight every week mainly by dieting and/or exercising. None of the jockeys consumed enough food during the weight loss period. Two jockeys were diagnosed with osteopenia and one was diagnosed with osteoporosis. Only history of fracture showed a significant correlation with low bone mineral density. All jockeys had more than one injury experience throughout their career. Fracture was the most common type of injury, occurring during practice and/or competition and caused mainly by difficulties in handling the horses.
Professional jockeys in Korea use extreme weight loss methods. Their repeated periods of poor nutritional intake may result in seriously low bone mineral density, which may aggravate injuries sustained during horse races. Implementation of balanced dietary programs and delivery of health education on weight management are urgently required.
本研究旨在调查减肥行为对韩国职业骑师营养状况、骨骼健康及受伤史的影响。
43名男性骑师完成了一份关于其减肥行为的调查问卷。其中，10名骑师被选中对其营养状况、骨骼健康及受伤史进行深入评估。
调查问卷显示，81.4%的骑师每周通过节食和/或锻炼来减肥。在减肥期间，没有一名骑师摄入足够的食物。两名骑师被诊断为骨质减少，一名被诊断为骨质疏松。只有骨折史与低骨密度存在显著相关性。所有骑师在其职业生涯中都有不止一次受伤经历。骨折是最常见的受伤类型，发生在训练和/或比赛期间，主要是由于驾驭马匹困难所致。
韩国职业骑师采用极端的减肥方法。他们反复出现的营养摄入不足期可能导致骨密度严重降低，这可能会加重赛马比赛期间遭受的损伤。迫切需要实施均衡饮食计划并开展体重管理健康教育。
