Effect of exercise during rehabilitation on swimming performance, metabolism and function of muscle in rats

1. It has been observed previously that gastrocnemius muscles from rats rehabilitated after early nutritional stress have low endurance and oxidative capacity (Raju, 1974). 2. Exercise during rehabilitation reversed the effects of early malnutrition on muscle function and metabolism. The swimming performance of rehabilitated rats was poor and exercise during rehabilitation improved it. 3. The specific activity of gastrocnemius muscle myosin ATP phosphohydrolase (EC 3.6.1.3) was not altered by either early malnutrition or exercise.
