An investigation was conducted to clarify both the effect of water polo training on bone mass and the effect of training-induced menstrual disorders on bone. The subjects were 12 female college water polo players and 7 age-matched sedentary college women as a control group. Menstrual conddition was evaluated by 12 montes of basal body tempenture measurement. Seven of the water polo players were eumenorrheic, and five had training-dependent (reversible) menstrual disorders (two with amenorrhea and three with cycle disturbances). Bone mineral measurement reveled differences between the water polo players and the sedentary women. The eumenorrheic water polo players had a higher bone mineral density (BMD) in the lumbar spine and total body skeleton than the sedentary control group, being 11.2% and 11.3% higher, respectiveIy. Effects of menstrual disorders (including cycle disturbance) were clear in the water polo players. The BMD of water polo players with menstrual disorders was 9.8% and 9.6% lower in the total body and lumbar spine that of eumenorrheic water polo players. Hormonal examinations revealed a lower serum estmdiol level in water polo playes with menstrual disordsers in comparison with eumenorrheic water polo playes. Serum estradiol level showed a positive corrlation with both total body BMD (r=0.78, p<0.01) and lumbar spine BMD (r=0.7l, p<0.01).
