ABSTRACT
Background: Menopause means permanent cessation of menstruation at the end of the reproductive life due to loss of ovarian follicular activity. Menopause is associated with a decrease in 17β-estradiol production in lungs, which are associated with increased systematic inflammation in the lungs. Women undergoing natural menopause differ dramatically from women experiencing surgical menopause. VO2 MAX refers to the highest value of oxygen consumption measure during a graded exercise test. The highest oxygen consumption value often occur in the last minute of exercise.
Objective: To compare VO2 max in natural and surgical postmenopausal women using the Queen's college step test.
Method: 30 subjects were selected with Normal BMI aged between 45 -55years. 15 subjects were women with natural menopause and 15 were women with surgical menopause. VO2 MAX was calculated using Queen's College Step Test. Subjects were instructed to step up and down on the platform(16.25 inch) at the rate of 22 steps per minute. Subjects were ask to step using a four-cadence,'up-up-down-down'for 3 minutes. Estimation of VO2 MAX can be calculated from the test results using the formula (McArdle et al.1972) Women: VO2 Max(ml/kg/min) = 65.81 - (0.1847 x heart rate (bpm).
Result: Statistical analysis showed that there is a significant difference of VO2MAX in natural and surgical postmenopausal women
Conclusion: Thus our study concluded that there is significant difference of VO2 max in natural and surgical postmenopausal women where VO2 MAX is more affected in women with surgical menopause then compare to natural menopause.
Key words: VO2 MAX, Natural Menopause, Surgical Menopause, Queens College Step Test, Oxygen Consumption.
