The purpose of this study was to examine the relationship between physique and physical fitness of school children in Japan, Thailand and Cambodia. Eight target areas were selected in Cambodia: Phnom Penh, Battambang, Kompong Cham, Sihanouk Ville, Kompon Chhnang, Svay Rieng, Kratie and RattanakKiri. The target area of Thailand was Udon-Thani Province. The subjects were children, whose ages ranged from 12- to 15-years, selected from the schools where the investigation took place (430 girls and 490 boys in Thailand, 631 girls and 677 boys in Cambodia). The research was carried out with regard to height, weight, sit-ups, sitting-trunk-flexion, side-steps, 50m-run, and standing-long-jump. As for Japan, data obtained by the Ministry of Education, Culture, Sports, Science and Technology were used.
The results were:
1) As for the physique: Thai tended to be approaching Japanese in girls and boys. Cambodian was worse than Japanese and Thai.
2) In 50m-run of girls and boys, a physique element was reflected by the exercise capacity.
3) In sit-ups and standing-long-jump of boys, a physique element was reflected by the exercise capacity.
