RELAÇÃO ENTRE FORÇA MUSCULAR E ÁREA DE SECÇÃO TRANSVERSA MUSCULAR EM ADULTOS JOVENS SEDENTÁRIOS

Abstract

The purpose of this study was to determine the - ::hip between muscle cross-sectional área -zmãted and máximum dynamic strength ofkne extension and elbow flexión. The sample was wistituded by healthy and untrained young males (n = 10). The máximum dynamic strength was measured by the test one máximum repetition (T RM). The estímate of muscle cross-sectional área was calcúlate with the Gurney equation (1973). The results do not showed relationship between máximum dynamic strength and muscle crosssectional área estimated (p>0,05) and a great variability ofthe subjeets. This variability can be influenced by factor with the levei of physical activity (affecting the neuromuscular coordenation and the inhibitory mechanisms) and by variation in the distribution of dijferent fibre types in each subjects. These results make impossible the modulation of the load of training through muscle cross-sectional área estimated, due to the great variability founded in the available subjects.
