Single intensive physical exercise caused phase alterations in content of myoglobin and tropomyosin in rat skeletal muscles. Within the first 2-4 hrs of rest concentration of myoglobin and tropomyosin was decreased in muscles by 40-50% (catabolic, urgent step of adaptation). Within the later period of rest (72-120 hrs) content of myoglobin and tropomyosin… (More)
It is established that the content of tropomyosin in skeletal muscles of rats increases due to the action of the systematic physical exercises of the speed-force direction. Suprareduction of tropomyosin in remote periods of rest after a single load is a biochemical basis of this process.
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… (More)
