To assess the discriminative ability of several fitness dimensions and anthropometric attributes for forecasting competitive success in female karate athletes.
Fitness and anthropometric data from 98 female junior karatekas obtained during the training camps of the Spanish National Karate Federation between 1999 and 2012 were used. Binary logistic-regression models were built to ascertain whether the set of fitness and anthropometric variables could predict future sporting-performance levels. For this purpose, participants were classified as elite (medalist in World or European Championships in the senior category) or subelite (at least a medalist in Spanish National Championships in cadet or junior but not included in the elite group), according to the results achieved up to 2019.
Participants who were subsequently classified as elite karatekas showed significant differences in agility, upper- and lower-body muscle power, and general fitness in comparison with those who were classified as subelite in the senior category. A total of 57 junior female karatekas who were subsequently classified as elite (7) or subelite (50) were included in the binary logistic-regression analysis. Resultant models showed significant capacity to predict karate performance.
Assessing physical fitness in junior categories can be a useful resource to determine future karate success. Coaches in this sport should pay special attention to the levels of muscle power and agility shown by their athletes, as both fitness dimensions could be indicators of future sportive success.
评估几种健康维度和人体测量属性对预测女性空手道运动员竞技成功的区分能力。
使用了 1999 年至 2012 年期间西班牙空手道联合会训练期间 98 名年轻空手道女运动员的健康和人体测量数据。建立了二元逻辑回归模型，以确定健康和人体测量变量的集合是否可以预测未来的运动表现水平。为此，根据截至 2019 年的成绩，参与者被分类为精英（世界或欧洲锦标赛高级别冠军）或次精英（西班牙全国锦标赛青少年或少年组至少获得奖牌，但不包括在精英组中）。
与在高级别中被归类为次精英的运动员相比，随后被归类为精英空手道运动员的运动员在敏捷性、上下肢肌肉力量和一般健康方面表现出显著差异。共有 57 名随后被归类为精英（7 名）或次精英（50 名）的年轻女性空手道运动员被纳入二元逻辑回归分析。结果模型显示出对空手道表现有显著的预测能力。
评估青少年组的身体健康状况可能是确定未来空手道成功的有用资源。在这项运动中，教练应该特别注意运动员表现出的肌肉力量和敏捷性水平，因为这两个健康维度都可能是未来运动成功的指标。
