The purpose of this study was to examine the effect and efficacy of dietary supplementation with cytochrome C, a reputed performance enhancer, on physiological and biochemical parameters. One female and eighteen trained male endurance runners participated in a double-blind, placebo (PL), crossover design study. The effect of oral ingested cytochrome C (C-C) supplementation on VO2peak, blood lactate (La-), ventilatory anaerobic threshold (Tvan), run time to exhaustion, heart rate (HR), and rated perceived exertion (RPE) was examined. Analysis of the data revealed no significant effect of oral ingested cytochrome C on VO2peak or run time to exhaustion. There were no significant differences between treatments for La- levels at VO2 peak, following a submaximal 13 min run or the 3 mile run (p>0.05). Tvan was not found to be significantly different between PL and C-C trials (p> 0.05) and no significant difference was noted for HR at Tvan between trials (p>0.05). No significant difference was observed between treatments for the subject's psychological perception as measured by RPE. These findings demonstrate that oral ingestion of 800 mg/day for 6 d and an additional 1600 mg of cytochrome C one hour prior to exercise has no significant measurable effect on VO2 peak, La-, Tvan, run time to exhaustion, HR, and RPE.
