优秀跆拳道运动员有氧代谢能力的特征

为了解我国优秀跆拳道运动员的有氧代谢能力的水平与特征。采用实验法,对我国23名优秀跆拳道运动员在递增负荷运动过程中各时段的气体代谢指标、生理、生化指标的动态变化情况进行测定分析。结果显示,运动员水平越高,VO2max越大,跆拳道运动项目要求运动员具备较强的有氧代谢能力,有目的的通过身体训练提高有氧代谢能力可促进运动员整体供能水平的提高; 通过递增负荷运动中RQ、HR、O2-pluse和BLa的动态变化规律,显示健将级运动员有氧、无氧代谢能力、心肺功能和耐受乳酸能力均优于一级运动员,揭示跆拳道运动水平与运动员有氧和糖酵解供能能力有着密切的关系。

On the Features of Aerobic Metabolism Capacity of the Elite Taekwondo Athletes

The aim of this study is to find out the features of aerobic metabolism capacity of the eliteTaekwondo athletes of 23 Chinese elite Taekwondo athletes. A lot of indexes were tested and analyzedin a load-increasing exercise. The results show that the better the athletes' capacities is, the higher theVO2max .This shows that the Taekwondo athletes should have a better aerobic capacity. The dynamicchanges of RQ, HR, O2-pluse and BLa in an increasing exercise reveal that the elite sportsmen'saerobic and anaerobic capacities, cardiorespiratory function and BLa tolerance are all superior to thoseof the lower level athletes. The conclusion is that the Taekwondo athlete's level has a close bearing onhis aerobic and glycolytic capacities.
