[Anaerobic threshold as determined by gas metabolic parameters].
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.
