Abstract
A special electrically operated dynamometer was designed for continuously measuring and recording the maximum effective concentric, eccentric, and isometric forces of forearm flexors and extensors, along with the degrees of the elbow angle. The data thus obtained were used to study the interrelationship between all of these forces. The eccentric forces of flexors and extensors were 32. 65% and 14. 22% greater than the concentric forces, respectively. The isometric force of flexors was 41. 64% greater than the isometric force of extensors. The eccentric force of extensors was significantly lower than the isometric and concentric force at the elbow angle of 140[degree]. Equations for each force curve were developed.This publication has 2 references indexed in Scilit:
