An annual plan was made for the purpose of improving physical strength of the members of a team of the Japan Industrial Women's Basketball League. Physique (body weight and skinfold thickness), maximum oxygen intake, maximum oxygen debt and hematological findings [hemoglobin, hematocrit, serum total protein and mean corpuscular hemoglobin concentration (hemoglobin/ hematocrit×100)] were measured in December 1978, May 1979 and December 1979 so as to see the effects of training. The subjects were 6 regular members ranging in age from 19.1 to 23.5. The results were as follows. 1. Physique was superior to the mean of the Japanese in the same age bracket by approximately 10cm and 10kg in body height and weight respectively. However, it was inferior to the mean of the six teams of the Japan Industrial Basketball League by 2-5cm in body height and 1-4kg in body weight. Skinfold thickness (triceps and scapula) was approximately 10 mm thiner than the mean of the Japanese. Body fat rate was close to 17.5% which is the functionally ideal value. All of the body weight, skinfold thickness and body fat rate were lowest in May 1979 but were recovered in December 1979 when it was the game season. 2. The maximal breathing capacity, maximum oxygen intake, oxygen pulse and maximum oxygen debt increased in December 1979 compared with the values in December 1978. The scores in these subjects were much higher than in average Japanese females, and also greater than in middle-distance runners. The increase of both maximum oxygen intake and maximum oxygen debt from December 1978 to December 1979 was approximately 18%. 3. Hemoglobin, hematocrit and serum total protein in December 1978 were in the lowest limit of normal range, tended to be anemic in May 1979 and recovered normal level in December 1979 by the improvement of diet. The mean corpuscular hemoglobin concentration was within normal limits in May 1979 when anemic symptons were recognized. Thus a sort of defensive reaction was observed in hematological indices. The above results indicated that considerable effects in respiratory and circulatory systems were induced by systematic training for one year. However, the occurrence of sports-induced anemia at an interval of training indicated the importance of diet control for the period of sports activities.
