Effects of long term physical training on body composition and physical fitness were studied on 110 healthy males aged between 28 and 34 years. Two and a half hours training of soccer, swimming, running, judo and other kinds of exercises were assigned to the subjects daily except Sunday for 8 months. Body weight, overweight, body fat, skinfold thickness, blood pressure, vital capacity, body flexibility, power, grip strength, maximal work capacity, and 6 kinds of sport tests were compared before and after the training. 1) Energy cost of the daily exercise was estimated at about 950 Cal., and intensity of the exercise was deduced to be 4 in RMR (corresponds to about 5 in Nets) on the average. 2) Body weight did not change significantly on the average. However, obese subjects lost their weight, Ian subjects gained, and normal weighted subjects did not change their weight significantly. 3) Body fat calculated from skinfold thickness decreased markedly, and the more fat the subjects had initially, the more fat they lost. 4) LBM increased in almost all cases. Obese subjects lost more fat than LBM they gained, and lean subjects gained more LBM than fat they lost, Normally figured subjects gained the same weight of LBM as the fat they lost. 5) Physical figure tended to converge by the training into some range in which the relationship between body weight and height is 4-5% more stout than that of average Japanese male adults. 6) Overweight calculated from weight and height may be used as a valid indicator of obesity for untrained people but not for well trained. While body fat can be a good indicator of that for the both groups. 7) Body fat of the subjects who had high work capacity was mostly under 13%, and that of the subjects whose work capacity was poor was mostly over 13%, while, that of the subjects whose work capacity was medium scattered in the both sides of 13%. 8) Performance of both aerobic and anaerobic exercise improved markedly by the training.
