The Investigation of Metabolic and Cardiovascular Responses to Fatiguing Static Effort.

Abstract

The research reported covers several approaches to the problem of isometric fatigue based on the working hypothesis that muscular fatigue is metabolic in nature. Obtained data support several important conclusions--at tensions of 70 percent maximum voluntary contraction fatigue is metabolic while at lower tensions some degree of transmission failure occurs, the integrated electromyogram per se is not a good measure of muscular fatigue but the frequency of the power spectrum may be; fatigue induced by isometric contractions is peripheral and does not involve central nervous fatigue.
