Riboflavin Depletion and Work Capacity in Humans

Abstract : Six moderately active young adults received a riboflavin-deficient diet ( 0.07 mg/day) for 56 days. Submaximal work performance was measured at three levels on the treadmill-4, 7, and 10% grade-all at 3.4 mph. Physiological parameters, e.g., heart rates, pulmonary ventilation, oxygen uptakes in ml/kg/min taken during the depletion-repletion periods were all essentially unchanged from pre-depletion values. The study demonstrated that performance was not significantly changed during riboflavin depletion as compared with pre-depletion value. (Author)
