极限负荷后四级定量放松活动强度对游泳运动员恢复效果影响的研究

Research on Effect of Relaxing Intensity of 4-Grade quantity After Maxminal Loading to Wwimmers′ Recovery

为研究极限负荷后放松活动强度对恢复效果的影响，选择血乳酸作为评定恢复效果的指标，设计了４级定量放松活动强度，对２２名游泳运动员进行实验。研究表明：放松活动强度影响血乳酸清除速率，在血乳酸清除速率方面Ⅲ级强度具有明显的优势其次是Ⅱ级强度；血乳酸下降曲线的特征，反映了血乳酸浓度与其清除速率，恢复时间有着密切的关系。

In order to research on the effect of intensity of warmming-down exercises after maxmial loading, BLA is chosen as index to decide recovery effect and the relaxing intensity of 4-gradequantity is desgned, According to the exercise and research on 22 swimmmers, the intensity of relaxing exercise influences BLA clearance volecity, in which the 3- grade intensity has obvious advantage and the next is the 2- grade intensity, BLA fal curve shows BLA concertration has close connection with its clearance volecity ...
