| Research Abstract |
We examined the effect of strength (70% of maximum voluntary contraction: MVC) and endurance exercise (30% of MVC) training and creatine supplementation (10 g/ day) on skeletal muscle and vascular structure and function during forearm immobilization. The result of this study indicated that exercise training was able to protect the decrease in muscle function, but creatine supplementation was not. No association was found between muscle blood flow and phosphocreatine recovery, an indicator for oxidative capacity, after submaximal exercise.
