摘要
目的:研究最大耗氧量速度(vVO2max)运动时运动员的生理反应,为中长跑训练处方的制订提供实验依据。方法:对12名中长跑运动员进行一次最大耗氧量(VO2max)递增负荷跑台测试和一次vVO2max力竭性跑台测试,测试受试者的VO2max、vVO2max、Tmax和tlim。结果:vVO2max持续运动中达到的VO2max和递增负荷测试达到的VO2max没有显著差异(P>0.05),且呈高度相关(R=0.857,P<0.01);vVO2max持续运动中,前60%Tmax时间内75%受试者摄氧量达到98%VO2max以上,部分受试者达到甚至超过VO2max。结论:vVO2max是一个有效诱导VO2max产生的强度,vVO2max、Tmax可以作为中长跑训练的参考指标。
To investigate the physiological response of athletes at velocity of ·↑VO2max exercise,with the purpose to provide the experimental basis in making the training prescription of middle and long distance running. 12 runners were tested by treadmill including one incremental test with ·↑VO2max and one constant running with velocity of ·↑VO2max. The ·↑VO2max, velocity of ·↑VO2max,Tmax and tlim of subjects were determined in two tests. The result showed that there was no significant difference for ·↑VO2max between incremental and constant running groups,which tended to close relationship between two groups. During constant running with velocity of ·↑VO2max, 75% of subjects reached the 98% of ·↑VO2max at exercise duration of 60% Tmax,and some subjects even excelled the ·↑VO2max. It concluded that velocity of ·↑VO2max was effective elicit for intensity of ·↑VO2max. Velocity of ·↑VO2max and Tmax can be the parameter in middle and long distance running.
