児童の体力差に関する分析的研究 : 日本・タイ・インドネシア児童相互間の比較

Abstract

In a further investigation of the characteristics in physical fitness of primary school children of three nations, Japan, Thailand and Indonesia, the results obtained on several tests (body height, body weight, chest circumference, skinfold fat, upper arm girth, leg length, hand grip, 50m dash and standing broad jump) were statistically compared among six groups of urban and suburban school children of Japan, Thailand and Indonesia and the possible effects of living conditions on physical fitness were discussed. The results obtained were as follows : A) Comparisons among three urban groups. The Japanese group was better than the other two groups on the whole but there was no significant difference between the Thai and Indonesian groups. B) Comparisons among three suburban groups. The Japanese group was better than the other two groups in all test items except in skinfold fat. On the other hand, the Thai group was nearly comparable to the Indonesian one. C) Comparisons between urban and suburban groups of each nation. The ability to run the 50m dash was always better in suburban groups than in urban ones in all of the three nations. With this exception, however, urban groups were better than suburban ones in Thailand as well as in Indonesia and no definite differences between urban and suburban groups could be found in Japan. D) Comparison of an urban group of one nation with suburban groups of the other two nations. (1) The Japanese urban group was clearly better than the Thai and Indonesian suburban ones; (2) The Japanese suburban group seemed to be better than the Thai and Indonesian suburban ones; (3) The Thai urban group was better than the Indonesian suburban one; and (4) the Indonesian urban group was better than the Thai suburban one.
