IMPROVING EXPLOSIVE BODY CAPACITY IN FEMALE SHORT TRACK SPEED SKATERS

ABSTRACT Introduction The peculiar characteristics of short track speed skating should be integrated into the psychology of competitions; it is considered that elite athletes engaged in this particular sport should have a healthy psychic condition. Objective Investigate the explosive power of female speed skaters in short track speed skating. Methods 10 key athletes from the national short track speed skating team were selected, and explosive power was tested by T-test, hexagonal test, and pro sensitivity test. Data analysis was performed using an independent sample t-test, differences in the results of related test indicators between groups were analyzed, and repeated measures analysis of variance was used. Results During the explosive kick phase, knee extension speed increased linearly from 210°/S to 600°/S, and hip extension speed increased linearly from 200°/S to 400°/S. Conclusion The development of muscle group strength and explosive power during training often shows differences in the degree of contraction, which is related to the arrangement of training methods. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.摘要 引言：短道速滑的专项特性需融入竞赛心理范畴；学界普遍认为，从事该专项运动的精英运动员应具备良好的心理状态。 研究目的：探究女子短道速滑运动员的爆发力水平。 研究方法：选取国家短道速滑队的10名重点运动员，采用T检验（T-test）、六角形测试（hexagonal test）以及灵敏性测试（pro sensitivity test）对其爆发力进行测评；数据分析采用独立样本t检验（independent sample t-test），分析组间相关测试指标的结果差异，并运用重复测量方差分析（repeated measures analysis of variance）。 研究结果：在蹬冰爆发阶段，膝关节伸展速度从210°/S线性提升至600°/S，髋关节伸展速度从200°/S线性提升至400°/S。 研究结论：训练过程中肌群力量与爆发力的发展往往呈现收缩程度的差异，这与训练方法的安排密切相关。 证据等级II；治疗性研究——治疗结局调查。
