Effect of Taking in Soybean Milk on the Bone Density and Female Hormone Concentration in Blood for Female Long Distance Runners
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.26 Vol.26】
Female long distance runners were had 600 ml of soybean milk a day. In this study, we examined the influence of soybean milk take on the bone density and the female hormone concentrations in blood. The following results were clarified.
1) The increase rate of the amount of the bone density in taking/exercised group was significantly higher that of both a control (non-taking) group and taking/nonexercised group (p<0.05).
2) We observed the tendency of the decrease of bone formation boning the metabolic marker in soybean milk taking group compared with control group.
3) During experiment, estrogen (E2)
concentration were not changed in both taking in and control group, but after experimental period, we observed increase of it's concentration in taking group compared with control group.
4) The persons with amenorrhea before take the soybean milk, they reappeared the menstruated for take the soybean milk.
From these results, take the soybean milk by female long distance runners seems to be useful for the increase of bone density and production of female hormone concentrations in blood.
