Background: The physiological role of oestrogen on the cardiovascular system is well studied during phases of the endometrial cycle. There is very high rise in both progesterone around 37% and oestradiol around 13.5%, in the previous studies it has been observed there FSH and LH plasma levels do not change in trained exercising females. Hence this study was aimed to see the restrictions of the cardiovascular system adaptability to exercise in follicular phase of endometrial cycle in peri-menopausal females.
Material and Methods: The study included healthy females adults aged between 42-45years, the participants who had undergone regular training and had participated in competitive running events 3-4 years in middle distance were selected in the athlete group and other set of participants had no regular exercise schedule or training program were selected for non-athlete group. Dynamic cardiac functions were measured before exercise in both the groups and after standard protocol of treadmill testing, they were evaluated.
Results: The study results showed a statistically significant variations in cardiovascular function parameters due to exercise per se in each of two of the groups of athletes and non-athletes.
Summary and Conclusion: The present study observations and results supports the theory from the previously studies that the most restricting component in the distribution of oxygen to the tissues is the cardiovascular system even under the potent influence of oestrogen hormone during follicular phase of endometrial cycle and which exercise further accentuates it.
