Physical load was modeled by swimming. The investigation was conducted in one, three, and five month's period after physical load. In gastrocnemius muscle and myocardium in both age animal groups after one month of moderate physical loads prevails the activity of enzymes of anaerobic respiration, which demonstrates the metabolic instability. The processes of tissue respiration disturbance, act as a disconnector of oxidative phosphorylation. In gastrocnemius muscle this disturbance decrease after 3 month and in cardiac muscle--after 5 month of swimming. The complex of changes in myocardium and skeletal muscle indicates on the adaptive reaction of structure (hypertrophia and hyperplasia) and realized as a "trained" effect of systemic physical exercises.Read More
