Aerobic work capacity and endurance during nutritional repletion of severely undernourished men.

摘要: Oxygen consumption in maximal exercise (VO2max) was found to increase during nutritional rehabilitation of severely undernourished, sedentary adult males only when dietary protein increased from 27 100 g/day. Adequate caloric intake, maintained for 45 days before the content diet, had no effect on VO2max. The VO2max values were correlate best with creatinine excretion rates (an index muscle cell mass) at different stages repletion. average increment VO2max/muscle mass ratio, although significant, a small magnitude (+15%). ratio correlated blood and plasma volumes After 2.5 months repletion still lower than those mildly undernourished or normal Colombian males. Maximal endurance time 80% aerobic load decreased significantly an 113 min beginning hospitalization 42 end period This could be result replacing carbohydrate calories producing depletion glycogen stores, and/or "detraining" effects associated hospital life.
