Maximum Local Muscle Energy Metabolic Rate in Athletes

Abstract

Three distance runners and three oarsmen were subjected to the prediction of maximum local energy metabolic rates of main seven muscle groups. Total energy metabolic rates and integrated bipolar surface electromyograms of the seven muscle groups were simultaneously measured during fifteen static resting and exercising items. The measurements of electromyograms were also performed during maximum voluntary contraction. Oarsmen had higher mean maximum energy metabolic rates than distance runners and non-athletes in the muscles of the anterior abdominal wall, the erector spinae muscles, the anterior femoral muscle group and the posterior crural muscle group. The muscle groups, of which mean value was higher in distance runners than in oarsmen and non-athletes, were the muscles of the buttock, the posterior femoral muscle group and the anterior crural muscle group. Nonathletes showed the least mean value in each muscle group except the posterior femoral muscle group. The present results confirmed that the maximum local muscle energy metabolic rates reflected daily prolonged heavy exercises.
