In order to demonstrate the possibility of evaluating anaerobic threshold (AT) by gas exchange parameters, treadmill exercise tests were made by 1-min increment protocol in 25 healthy young men. Ten parameters of gas exchange were collected when AT was reached. The analysis showed that correlation between VO2 and VE (r = 0.8004) or VCO2 (r = 0.9743) are high. While correlation between VO2 and RQ (r = 0.4491) or HR (r = 0.4666) are significantly lower. So the accuracy of VE and VCO2 is higher than that HR or RQ for the determination of AT.
为了证明通过气体交换参数评估无氧阈（AT）的可能性，对25名健康年轻男性采用1分钟递增方案进行了跑步机运动测试。当达到无氧阈时收集了10个气体交换参数。分析表明，VO₂与VE（r = 0.8004）或VCO₂（r = 0.9743）之间的相关性很高。而VO₂与RQ（r = 0.4491）或HR（r = 0.4666）之间的相关性则显著较低。因此，在确定无氧阈时，VE和VCO₂的准确性高于HR或RQ。
