The Effects of Menstrual Cycle Status on Bone Mineral Density and Hormone in Female Athletes

&nbsp;&nbsp;The study aims at investigating the influences of athletic menstrual irregularities on bone mass and hormone of female athletes. 70 female athletes(comprising of 14 runners, 14 swimmers, 14 handball players, 14 weight lifters and 14 ballet dancers) and 14 female students of age control group were selected for this study.<BR>&nbsp;&nbsp;Bone mass was measured in the lumber spine, femur neck, trochanter, ward&quot;s triangle and total body by dual-energy X-ray absorptiometry.<BR>&nbsp;&nbsp;The hormone analysis of estradiol, prolactin, LH and FSH was measured.<BR>&nbsp;&nbsp;The results are follows;<BR>&nbsp;&nbsp;1. The group of handball players and weight lifters had a higher bone density in spine and femoral trochanter than other groups. The group of handball players had a higher bone density in femur neck than the groups of runners, swimmers, ballet dancers and controls. The group of handball players had a higher bone density in ward’s triangle than the groups of swimmers and ballet dancers. The groups of handball players and weight lifters had a higher bone density in total body than groups of runners, swimmers, ballet dancers and controls. The group of runners had a higher bone density in femoral trochanter and total body than thc group of swimmers.<BR>&nbsp;&nbsp;2. Bone density in all measurement sites was significantly lower in the group of ballet dancers with amenorrhea than in the group of regularly menstruating ballet dancers. Bone density in lumbar spine and total body was significantly lower in the group of weight lifters with amenorrhea than in the regularly menstruating group. Bone density in spine was significantly lower in the group of swimmers with amenorrhea than in the regularly menstruating group. Bone density in femur neck was significantly lower in the group of runners with amenorrhea than in the regularly menstruating group. However. bone density in all measurement sites was significantly higher in the groups of handball players and weight lifters with the regular menstruation than in the control group. Bone density in femur neck and trochanter was significantly higher in the group of runners than in the control group. Bone density in femur neck was significantly higher in the group of ballet dancers than in the control group. However, the group of ballet dancers with amenorrhea had a significantly lower hone density in lumbar spine than the control group, while the group of handball playerswith amenorrhea was significantly higher in all measurement sites than the control group.<BR>&nbsp;&nbsp;3. E2 was significantly lower in all the groups with amenorrhea than in the regularly menstruating group, while LH was significantly higher in the group with amenorrhea than in the regularly menstruating group.<BR>&nbsp;&nbsp;4. E2 was significantly lower in the group of runners with amenorrhea than in the group of runners with the regular menstruation, while LH was significantly higher in the group of ballet dancers whth amenorrhea than in the grouup of ballet dancers with the regular menstruation.<BR>&nbsp;&nbsp;5. Weight, body mass index and the percentage of body fat was significantly higher in the regularly menstruating group than in the group with amenorrhea. Weight, body mass index and lean body mass was significantly higher in the regularly menstruating group than in the control group, while the percentage of body fat was significantly lower in the regularly menstruating group than the control group. Lean body mass was significantly higher in the group with amenorrhea than in the control group, while the percentage of body fat was significantly lower in the group with amenorrhea than in the control group. The age of menarche of the group with amenorrhea was late in comparison with the regularly menstruating group.<BR>&nbsp;&nbsp;However, as for the comparison of body composition according to the menstruation cycle by athletic events, height, weight, body mass index and the percentage
