Effects of isometrical training on the force-time characteristics of muscle contractions
Improvement in the diagnosis of the nervous and muscular systems in man is of primary interest in several scientific research laboratories. Some of the results have emphasized the importance of evaluating muscular contraction not only from the standpoint of the quantity of developed tension but also that of the time required for its development. Changes of both parameters have been investigated in subjects under the influences of fatigue (Natori, 1970; Royce, 1962), occluded blood circulation (Natori, 1970; Royce, 1958) and changes of extreme temperature (Clarke and Royce, 1962). Previous work has focused on the influences of age, sex, fatigue, and various sport activities (Potměšil and Sukop, 1969; Sukop and Reisenauer, 1967, 1968, 1969).
