Abstract

Sixteen healthy male subjects classified as sedentary (8) or active (8) exercised to exhaustion on a bicycle ergometer at a load requiring approximately 70% of their aerobic capacity. Biopsy samples were taken from the vastus lateralis at rest and at fatigue. A 12 week training program increased skeletal muscle debranching enzyme activities twofold. Submaximal and maximal exercise to exhaustion resulted in decreased debranching enzyme activities. The results indicate that debranching enzyme activities correlate highly with total phosphorylase activities after submaximal and maximal work to fatigue.
