就学段階ごとの運動経験が大学生における把握の調整力に及ぼす影響

Optimal control of muscular strength at submaximal levels is a more important ability in actual practice of several physical activities and sports performance than maximal strength. Based on actual situations, in this study, we examined the influence of individual history of exercise during various school ages on the coordination ability in grip strength of college students. We measured the maximal voluntarily handgrip strength of 438 healthy university students, and their voluntary isometric grip strength performed at the target values (30%, 50%, and 70% of maximal grip strength) depending on subjective effort. The effects of several variables, as exemplified by the target values, sex, maximal handgrip strength, and estimated exercise volume (the product of exercise period and intensity) in each school age (preschool, lower and upper elementary school grades, junior high school, high school, and university), on the differences between the target and measured values at several grip strength levels were statistically considered in a multilevel model analysis. These results suggest that the exercise volume in the lower elementary school grades had a large effect on muscular contraction control later in adolescence. In addition, these findings indicate the need to reexamine the practice of exercise among elementary school students.
