Prediction of Maximum Local Muscle Energy Metabolic Rate in Voluntary Sustained Contraction

Abstract

In order to determine the maximum local energy metabolic rates of seven muscle groups during maximum voluntary contraction (MVC), an application of our prediction method of local muscle energy metabolic rate (YOKOYAMA, 1980a) was considered. Total energy metabolic rates and integrated bipolar surface electromyograms of the seven muscle groups were simultaneously measured during sixteen static contraction conditions. The measurements of the electromyograms were also performed during MVC. The subjects were seven Japanese healthy males between the age of 20 and 31 years. The predicted maximum energy metabolic rates were 254.047±139. 726(mean± S.D.) [n=7] in the muscles of the anterior abdominal wall, 126.343±49.672 [n=7] in the erector spinae muscles, 131.091±35.575 [n=7] in the muscles of the buttock, 80.169±20.689 [n=7] in the posterior femoral muscle group, 154. 977±38.362 [n=7] in the anterior femoral muscle group, 75.838±38.290 [n=7] in the posterior crural muscle group and 34.475±9.583 kcal/h [n=5] in the anterior crural muscle group.
