This study aimed to know the effects of three marine training items, swimming, rowing and yachting on pulse, lung capacity and weight. The experiment subjects were composed of ten each item and were tested for six days. The experiment groups were strictly controlled in eating time, food amount, sleeping time and training intensity. The level of training intensity was 70~80% of maximal pulse rate. In the training intensity of each item the speed was decided after examination in advance, and the trainees kept the speed during training. The contents of training were made up through enough examination. The conclusions were as follows. 1. The effect on pulse in average value showed the decrease of 1.80round/min swimming, 1.51round/min rowing, and 0.11round/min yachting, but it was not admitted as significant difference. And in average value, swimming showed the decrease of 0.26round/m than rowing and 1.69round/m than yachting. 2. The effect on lung capacity showed the increase of 66.66cc swimming, 42.97cc rowing, and 4.22cc yachting, but there was no significant difference. And the average value of swimming showed the increase of 23.66cc than rowing, and 62.44cc than yachting. 3. The effect on weight showed decrease of 3.45g in swimming, 3.24g in rowing, and 2.07g in yachting. Swimming and rowing proved to have significant difference (p<.05). And in average value, swimming showed the decrease of 1.175g than rowing, and 1.38g than yachting. On the whole, in all experiment items, pulse, lung capacity and weight, the change was in the order of swimming, rowing and yachting after experiments.
