摘要

Sex hormone, bone turnover and blood lipids have a close relationship with individual health regimen. Physical activities are thought to have good effects on sex hormone, bone turnover and blood lipids; however, there are still many controversies. This study tries to investigate the effects of aerobic exercise and physical education class on college girls' sex hormone, bone turnover and blood lipids. Forty-five healthy college female students (age 20-25 year old) volunteered to participate in the study. They were randomly assigned to aerobic group (A), physical education group (PE) and a control group (C) with no training, and received experiments for 12 weeks. Group A received a regular schedule on aerobic exercise (50 minutes each time, two times a week) with the average intensity reaching fifty to seventy percent of the individual HRmax. Group PE focused on neither physical intensity nor any sporting events. They practiced twice a week with each session lasting 50 minutes. Group C was not allowed to participate in any physical activities. Venous blood and urine samples were taken before and after the experiment in a resting state (12-hour fasting) at 8:00 am in the luteal phase (the twenty-fourth day of menstrual cycle) for determination of sex hormone (follicle stimulating hormone, FSH; luteinizing hormone, LH; estradiol, E2; progestogen, P and testosterone, T), blood lipids (total cholesterol, TC; triglycerides, TG; high-density lipoprotein, HDL and TC/HDL) and bone turnover marker (deoxypyridinoline, DPD). The results were (1) aerobic exercise and physical education has no significant effects on FSH, LH, E2, P (p＞0.05), but will significantly reduce the amount of T in blood (p＜0.05). (2) aerobic exercise and physical education can prevent bone loss (p＜0.05 and p＜0.01 respectively). (3) physical education has on significant effects on blood lipids (p＞0.05); aerobic exercise has no significant effects on TC and TG, either (p＞0.05), but has significant positive effects on HDL (↑, p＜0.01) and TC/HDL (↓, p＜0.05).
