Changes in VO2 (left-hand panels) and ventilation (VE, right-hand panels) as a function of performance time during the time trial test, before and after either RMET (top two panels) or a period of no training (control group, C, bottom two panels), in two representative subjects. The filled circles represent data obtained before the period of training, and the shaded triangles are the post-training values. The subject in the RMET group showed an increase in VE and VO2 after training, mirroring the changes observed with constant work-rate exercise. The control subject showed no changes between the first and second test. See text for a more detailed explanation, and Table 3 for the average data.
