500m短道速滑主要依靠乳酸系统供能,发展短道速滑运动员乳酸系统供能能力是取得优异成绩的重要条件之一。本研究通过Wingate试验,观察优秀青少年短道速滑运动员的无氧功及其运动后血乳酸峰值等相关指标的变化,以判定该群体乳酸系统供能能力,为科学训练提供参考。1对象与方法1.1 The 500m short track speed skating mainly relies on the lactic acid system for energy supply. The development of short track skater lactic acid system is one of the important conditions for achieving excellent results. In this study, Wingate test was used to observe the changes of anaerobic and post-exercise blood lactic acid peak of the elite young skater to determine the ability of lactate system in this group to provide reference for scientific training. 1 objects and methods 1.1
