Physical exercise induces phasic changes in the tropomyosin content and metabolism in muscles and its concentration in blood. The intensive catabolic processes (decrease of 14C-leicin inclusion and time of half-life) of muscle tropomyosin and its appearance in blood were shown 2-24 hours after the exercise. Intensive anabolic processes of muscle tropomyosin were found at the late period of rest (72-144 h). These results reveal the biochemical mechanism of muscle adaptation to physical exercise. Data on the tropomyosin content in blood permit recommending tropomyosin for development of the diagnostic test of functional condition of the skeletal muscle.
