男子青少年运动员心率拐点与心率变异阈的实验研究

Heart-rate deflection point and the heart-rate variability threshold of trained boys

通过对青少年心率拐点和心率变异阈的研究,发现心率拐点和心率变异阈可以做为推测无氧阈的重要指标。其中,心率拐点简便易行,但与通气阈的相关性较小,精确度较差,在一定程度上可以做为评价机体最大有氧能力的指标;心率变异阈较心率拐点更为敏感,可以作为评价机体最大有氧运动能力的有效指标之一。

The aim of the present investigation was to compare the accuracy of the heart - rate deflection point （ HRDp ） and the HR variability threshold （ HR VT） to predict anaerobic threshold in boys. The result show that the heart - rate deflection point is simple and easy to do, but the correlativity is less, also it can be an index to evaluate the individual maximal aerobic capacity; the HR variability threshold is more sensitive compared with the heart- rate deflection point, and it can be an effective index to evaluate the individual maximal aerobic capacity.
