A Study on the Human Muscle Power with Inertia Ergometer

Abstract

The relation between the strength and the power was investigated in the arm flexor and knee extensor muscles respectively. In order to measure the muscle power, a modified Inertia Ergometer and the muscel strength was ordinarily measured with spring dynamometer. It was found that the muscle power measure in four kinds of loads was significantly related to the strength of individuals, while some individual differences were observed. Based on the electromyograms and the force curves it was revealed that the power ability was determinded by how to concentrate their nerve impulses to the acting muscles in addition to the strength.
