Abstract
Background: The role of estrogen on the heart is well known in the normal course of the menstrual cycle. Significant increase in both progesterone (37%) and estradiol (13.5%), whereas no change in plasma FSH & LH was observed in exercising women in previous studies. Therefore this study was intended to see the limitations of the pulmonary system in adaptability to exercise in proliferative phase of menstrual cycle in perimenopausal women. Material and methods: Healthy adult females between 42-45 years who regularly undergo training and participate in competitive middle distance running events for at least past 3 years were considered in the athlete group whereas the non-athlete group did not have any such regular exercise program. Dynamic heart functions were measured in both groups before exercise was evaluated following standard procedure of treadmill testing.Results: It was observed that exercise per se cause a statistically significant change in dynamic heart function parameters in either of the groups. Summary and conclusion:This finding supports the hypothesis that the cardiovascular system is normally the most limiting factor in the delivery of oxygen even under the predominant influence of estrogen in proliferative phase which is further accentuated by exercise.DOI:10.21276/AAMS.1933References
