Serum Glutamic-Oxalacetic Transaminase Levels after Exercise in Men.

Serum glutamic-oxalacetic transaminase was determined in trained and untrained men after exposure to exercise through the Harvard Step Test or timed track events. The untrained human subjects exhibited a significant decrease in SGOT. In athletes, competing in timed track events, there was also depletion in serum transaminase titer. However, in well-trained athletes there was no alteration in serum transaminase level following the same exercise as that of the untrained men. The role of the adrenal cortex and its possible interrelationship with transaminase movements, as influenced by exercise and stress, was discussed.
