Summary This study was undertaken to further clarify the effects of exhaustive exercise on protein degradation. Measurement of urea and NT- methylhistidine, in both rats and humans, was utilized as an indicator of protein catabolism. In rats, an exhaustive exercise bout resulted in increased urinary levels of urea and NT-methylhistidine. Plasma NT- methylhistidine was also significantly elevated in rats after an exercise bout. Human studies too revealed increased excretion of urea (both urinary and sweat) and NT-methylhistidine accompanied by increases in plasma levels of NT-methylhistldine. The results from this study have demonstrated an increased protein utilization as the result of intense exercise. The large increase in NT- methylhistidine seen in the post-exercise samples Indicates that muscle catabolism is initiated by stressful exercise. The increase in urea from both sweat and urine is probably potentiated through two mechanisms: (1) the direct utilization of the carbon skeletons resulting from catabolism in the TCA cycle and (2) to restore lowered glucose levels in the body via gluconeogenesis.
