We examined the effects of exercise-induced amenorrhea on bone mineral content in female runners.Women were divided into five major groups: Group 1 included 11 amenorrheic runners who had no menses for the previous 6 months; Group 2, 5 oligomenorrheic runners, whose menses occurred every 6 weeks to 6 months; Group 3, 15 eumenorrheic or normal runners running a minimum of 20 miles per week; Group 4, 14 eumenorrheic normal controls not...References1.
