Correlation between the change in performance time and the change in VE with RMET. Values were computed as the difference between the values obtained on the pre-training test and the post-training test in the RMET group, and in the control and placebo group subjects. The correlation was statistically significant (r = -0.522, P = 0.0183), suggesting that the subjects that breathed more during exercise also had better performance, as reflected as faster times (negative % change) on the time trial test.
