(b)  

Variable**	CoQ10	Placebo	P value
Heart rate (bpm)	155.6±3.6	156.4±3.2	0.96
Perceived exertion (6–20 scale)	17.6±0.3	16.9±0.4	0.19

Values are mean ± SEM.
∗Heart rate and perceived exertion values taken during the final 15 seconds of minute 8 (stage 4) and minute 14 (stage 7) of treadmill testing; peak values for heart rate and perceived exertion taken at the end of the treadmill testing.∗∗Values are averages taken over five-, 10-second cycle sprints.
