N2  - Human skeletal muscle has been studied in vivo by 31P nuclear magnetic resonance. Older endurance athletes were compared with sedentary elderly subjects aged 60-70 years. Phosphocreatine-inorganic phosphate ratio (PCr/Pi), intracellular pH were measured. At rest, no differences were found between two groups. Aerobic dynamic exercise resulted in a similar reduction of PCr/Pi in both groups. The pH fall in exercise was not significantly different in the trained and sedentary subjects. Whenever, PCr/Pi and pH of two groups during exercise and recovery were lower than young adult subjects of the other study. These results suggest that there are small differences in energy production during exercise and recovery and aging process affect the metabolic ability of human skeletal muscle.   Verf.-Referat
