Muscle Glycogen, Fiber Type, Aerobic Fitness, and Anaerobic Capacity of WestCoast U.S. Navy Sea-Air-Land Personnel (SEALS)

摘要

Thirty-eight Navy SEALs performed aerobic fitness and maximal anaerobic capacitytests on a cycle ergometer. Lactic acid concentration was measured in blood samples taken during the aerobic fitness test. After recording prior dietary intake and physical activity, thirty-six subjects had biopsies taken from the vastus lateralis muscle. Biopsy results showed that SEALs averaged 55% fast twitch muscle fiber type. The muscle samples had a mean glycogen concentration of
