In this study, physical growth and development were compared between Korean and Japanese youth and children ranging in age 6 to 14 years old. Longitudinal data were collected from the samples of both countries, which were comparable in socio-economical conditions. Korean sample was extracted from Seoul and Japanese from Tokyo. Stature, sitting height, body weight and chest girth were chosen as the variables to investigate the physical growth and development. In general, Japanese boys and girls were larger in physique than the Korean until 6∼7 years old ; before growth spurt started, but thereafter, the Korean tended to be almost equal in body linearity to the Japanese and to be larger in body bulk than the Japanese. For the peak velocity age, the korean boys were younger in sitting height and chest girth than the Japanese, and the Korean girls were younger in stature, body weight and sitting height. Thus, as long as compared in peak velocity age, the Korean were considered matured earlier than the Japanese. Then, the samples were classified into three maturation groups in reference with peak velocity age, and these maturation gorups were compared in physical growth between both countries. The significant differences were recognized between three maturation groups in both countreis. Then, the relative growth of body weight, sitting height, chest girth to stature, and that of chest girth to body weight were investigated.

Body fat generally has been considered to be liable to physical fitness and motor ability. However, very few studies have been done on the relationships between body fat and physical fitness and motor ability. The purpose of this study was to clarify the relationships between percent body fat(%fat) and selected motor ability elements. The subjects were seventy-nine boys and ninety-eight girls aged 10-11 years. Selected motor ability variables were grip strength, back strength, 50-meter dash, running long jump, vertical jump, belly grind, side step, trunk flexion, trunk extension, modified chinning, zigzag dribble, softball throw, and step test. Skinfold thickness was measured at three sites(triceps, subscapular, abdomen)using an Eiken-type caliper. Percent body fat was measured using a tetrapolar bioelectircal impedance plethysmograph(Selco 891). Negatively affected variables by %fat were those which involved muscular power and coordination, while muscular strength was positively related with %fat. Flexibility variables were found not affected by %fat. The subjects were grouped according to %fat in order to further examine the effects of %fat on motor ability. The groups were less than 10%fat(lean), 10∼20%fat(standard)and greater than 20%fat(obese) in boys, and less than 15%fat(lean), 15∼25%fat(standard)and greater than 25%fat(obese) in girls. The results of comparision among groups clearly indicated that the obese groups were poorer in muscular power and coordination but greater in musular strength. The body fat may be one important factor that affects on many motor ability elements. The relationships between motor ability and degree of fatness seem to be rather complicated, and a great deal of data should be accumulated for analysis of influence of body fatness.
