Energy and Nitrogen Metabolism of Peripheral Tissues in Intact Man.
Abstract
To identify the metabolic alterations accompanying muscular hypertrophy, the net exchange of glucose, lactate, oxygen, and amino acids in ten healthy nontrained and six weight trained young male volunteers was measured before, during, and after sixty minutes of hand ergometer excerise. The forearm muscle conditioning program increased arm volume by 7% and wrist curl strength by 55%. The major metabolic differences between untrained and trained men appeared during exercise. The increase in glucose uptake and lactate release were significantly greater in untrained subjects. On the other hand, the increase in alanine release was greater in trained subjects. This suggests that less tissue hypoxia developed at the same moderate work load in hypertrophied muscle.
