【摘要】 本文提出了一个新的通气参数判断无氧阈的指标—“氧脉搏阈”。氧脉搏阈是以运动过程中氧脉搏的拐点来断定的。由于氧脉搏（VO2/HR）将心率因素引入摄氧量，使得这个指标对于人体摄氧效率的反应非常灵敏，正因为如此，也使得它在判断人体代谢过程、机能评定中均有很好的表现。这不仅为无氧阈无损测量指出新的途径，也使氧脉搏本身生理意义和实用价值的得到进一步的”挖掘”。为人体机能评定提供新的参考依据。通过研究得出以下结论：每搏摄氧量（氧脉搏）与每分摄氧量是具有差异的，二者在总体上趋同，但又各有各的特点。这些特点是具有生理意义的。也正因为二者的差异性决定了研究的必要性；氧脉搏在运动过程中存在拐点，可以判断无氧阈。氧脉搏拐点法判断无氧阈很准确；研究未发现氧脉搏与”瘦体重”有线性相关，笔者认为是样本较小、相关性较小所致。预计增大样本，二者应该存在一定的正相关；测试者的素质越好，摄氧量、氧脉搏、心率三者相关性越大，HR与HR/VO2曲线交汇位置与VAT2位置极为接近，可以用来判断无氧阈的位置；氧脉搏阈值、最大氧脉搏二者与最大运动时间均无线性相关。无氧阈或最大值的绝对氧脉搏（氧脉搏与体重的比值）与最大运动时间也无线性相关。提示我们不同个体之间不适宜用统一的氧脉搏值横向比较耐力素质。氧脉搏、摄氧量在最大值，无氧阈附近存在平台，平台与有氧耐力中度相关，可用来横向比较不同个体的有氧耐力。更多还原

【Abstract】 The paper proposes a piece of new respiratory index named oxygen pulse threshold(OAT) which can judge anerobic threshold(AT). OAT is the curve point of oxygen pulse(OP) at sport..OP is decided by HR and VO2, and it can response the efficiency of respiration sensitively . So just make it is good to judge the metabolic course and evaluate enginery of human body. It lead to a new way for scatheless measure of AT,and we get further reliazing the applying values and phisiological meanings of AT itself. OAT Offers a new piece of index for the evaluating of human function. Produce following conclusions through research:. there is some difference between VO2 and OP.The two respiratory parameters are convergent on the whole, but there are characteristics .These characteristics have physiology meaning. Just because the difference quality of the two has determined the necessity studying too；OP has flex point which can be used to judge AT in the course of sport ,and research proves that the means is more accurate；Research proves that no positive pertinency is between OP and HR,but the author believe it only accounts for lack of the quizzees；The better the enginery of human is,the higher the positive pertinency among VO2、OP and HR is.The crossing of HR and OP is very near to the point of VAT2,the character can be used to judge AT；NO pertinency is among OAT 、OPmaxand tmax.That shows the number of OP can not be compared among different individuals . OP and VO2 have "platform" near the point of AT and their maximum.There is medium positive pertinency between the length of the platform and tmax.It shows platform can be compared with others ,and we can conclude aerobic ability of different individuals by platform.更多还原
