Objective: The aim of the present study was to calculate and compare VO2max between premenopausal and post menopausal women.

Materials and Methods: A cross-sectional study was conducted between 60 premenopausal women in the age group of 40-45 years and 60 post menopausal women in the age group of 45-50 years. All 120 subjects underwent treadmill test under modified Bruce protocol. VO2max was calculated from MET (1 MET= 3.5 ml of oxygen /kg body weight /minute).

Result: Postmenopausal women had a lower VO2max than premenopausal women, which may be associated with a higher total and visceral fat mass in postmenopausal women.

Conclusion: Our data suggested that postmenopausal women had a lower premenopausal women.
