Women and exercise. ACOG Technical Bulletin Number 173--October 1992

Exercise programs for women can serve many purposes, including developing fitness; controlling weight; improving strength, flexibility, and coordination; enhancing competition with other athletes, and promoting general good health. Depending upon the goal, a realistic method of exercise should be chosen and a program should be developed and followed carefully. Most programs will require aerobic training, which is best maintained by using training heart rates. Exercise is not without the potential for problems, and any warning signs should not be ignored. As the intensity of the program increases, it may have effects on the reproductive system varying from minor menstrual changes to amenorrhea. The physician needs to be aware of these occurrences, and evaluation is necessary to ensure that no other pathology has occurred. When carefully selected and appropriately followed, an exercise program will result in a healthier patient.
