摘要
本研究探讨了奥林匹克举重男女运动员的体重管理方法,假设运动员参加比赛时的体重比他们习惯的训练体重(即制造体重)轻。通过一项经过验证的匿名调查,我们收集了 149 名奥运举重运动员(年龄大于 18 岁;女性 = 94 名)的数据。调查包括五个部分:人口统计学、训练/比赛历史、体重历史、影响来源和体重管理方法。采用单因素方差分析法对BM管理的流行率、程度和方法进行了分组分析。在发现显著影响时,还进行了包括斯皮尔曼 rho 和卡方分析在内的事后测试。四分之三(76%)的运动员承认使用慢性减肥和/或急性减肥策略来减轻体重。赛前一周的正常体重减轻(2%-3%)符合推荐准则。循序渐进的节食、液体限制和低食物重量、高热量选择是最常用的排便管理策略。与男性运动员相比,女性运动员更倾向于使用渐进式节食法(p = .043; r = .104),而增加运动量(p = .046; r = -.105)和禁食(p = .038; r = .05)的可能性较低。女性还认为营养师/营养学家 (p = .006; r = .022) 是极具影响力的信息来源。这项研究为奥林匹克举重运动员的体重管理实践提供了新的视角,发现大多数运动员在比赛时的体重都比其惯常训练体重轻,并采用了一系列慢性减肥和急性减肥策略。
Body Mass Management Practices of Olympic Weightlifting Athletes.
This study explored the body mass (BM) management practices among competitive male and female Olympic weightlifting athletes, hypothesizing that athletes compete in lighter weight categories than their habitual training weight (i.e., making weight). Utilizing a validated, anonymous survey, data were collected from 149 Olympic weightlifting athletes (>18 years; female = 94). The survey comprised five sections: demographics, training/competition history, weight history, source of influence, and BM management practices. The prevalence, magnitude, and methods employed for BM management were analyzed with subgroup analysis using one-way analysis of variance. Post hoc testing including Spearman's rho and chi-square analysis was completed when a significant effect was found. Three quarters (76%) of athletes acknowledged using chronic weight loss and/or acute weight loss strategies to make weight. Usual BM loss (2%-3%) in the week before competition was within recommended guidelines. Gradual dieting, fluid restriction, and low food weight, high-calorie options were the most commonly used BM management strategies. Female athletes were more likely to use gradual dieting (p = .043; r = .104) and were less likely to increase their exercise (p = .046; r = -.105) and utilize fasting (p = .038; r = .05) compared with their male counterparts. Women further identified dietitians/nutritionists (p = .006; r = .022) as a highly influential source of information. This research offers new insights into the BM management practices of Olympic weightlifting athletes, identifying that the majority of athletes compete at a BM lighter than their habitual training weight, achieved using a range of chronic weight loss and acute weight loss strategies.
