The Basic Study of the Hand Grip -Morphological Development of the hands of the Students-
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.4 Vol.4】
The consideration of the diameter of the grip portion of sports and physical fitness equipment is important because it is closely connected with the development of performance and the prevention of sports injury.
This study was conducted in order to measure the length and area of the hands of Japanese boys and girls. Five hundred and twenty four boys and four hundred and sixty three girls participated in this study.
The parameters of this study were hand length, finger length, hand area, the diameter of the circles formed by the thumb and each finger, and the angles between the fingers.
The results were as follows:
1) In general, the development of the hand has the same tendency as the development of body height.
2) On the diameter of the circles formed by the thumb and each finger and the angles between the fingers, however, different growth patterns were observed among the forth grade primary school children and second grade junior high school students.
3) The ratios between the five fingers and metacarpale length and the ratio between the length of five fingers were constant in every school grade.
4) High correlation coefficients were found between hand length and body height, and the diameter of the circles, and hand arer, but negative correlation was obtained between hand length and the angles between fingers.
The utilization of the results of this study is expected to help in the design of sports wear, sports equipment and facilities.
