The purpose of this study is to obtain the effects on clothing weight in the health state of the kindergartners. So 1 divided 140 kindergartners into 3 groups. A not trained of light wearing in the control group, B the semi-experimetnal group, C the experimental group. In the field surveys conducted their monthly clothing weight and anthropometric measurements, physique index (obesity index) and motor-ability and rate of cold contraction and of absence, Cornell Medical index from Jun, 1986 to Feb, 1987 in Seoul. 1) The experimental group was even less clothing than the control group in clothing weight during the training period. 2) All the experimental group droped conspicuosly the rate of cold contraction and absence during this period. 3) After this training, the experimental group was better than semi-experimental group and control group in motor-ability especially in standing broad jump, flexibility and tennis ball throw, 25 meter dash. 4) But, 1 could not find the different of anthropometric-measurements, physique-index about this train.
