Identity plots comparing time trial performance before (Pre) and after (Post) the intervention period in the RMET group (top panel) and in the control (bottom panel, open squares) and placebo (bottom panel, filled triangles) groups. Note that all but one subject in the RMET group improved their performance time, and that only three subjects in the control and placebo groups improved (two controls, one placebo), and then only marginally.
