Abstract:
A certain inhibitory effect upon the function of deep sensory mechanism of the muscle seems to be associated with the improvement of muscular strength resulted from an intensive training. At the basic weight around 1.0-3.5kg., a trained person shows : (1) a decrement in the ability of identifying different weights held in both hands ; and (2) a decrement in the ability of gradgin the half-way strength of the maximum grip strength. Even after the repeated five trials, these subjects could not approach the half-way strength in their self-grading muscular strength.
When the maximum exertion was repeated five times in the measures of grip strength or leg extension, the performance in the fifth trial is usually considerably worse than that in the first trial. This decrement rate varies considerably in accordance with the difference in the training method. As the mechanism of muscular exertion is habituated to labor, the decrement rate becomes smaller. In this measurement, the muscular ability in single maximum exertion is the concern ranther than the fatigue of the muscle.
The contact dimension of the foot to the ground decreases with the movement of the lower legs. By measuring this dimension, the amount of the milking action in the muscles may be estimated. There is no correlation between the amount of the milking action and the muscular strength in the static contraction.
