Isolated and Associated Effects of Physical Exercise and Estrogen Therapy on Climactercs Women

• Status: Completed
• Trial end date: 2009-02-01
• Target enrollment: 0
• Participant gender: Female

Summary

This study will investigate the isolated and the associated effect of estrogen therapy and physical exercise in the function, regulation and cardiovascular risk markers of 60 postmenopausal women, (45 - 60 years old). The volunteers will be randomaized into two groups: estrogen therapy (estradiol valerate 1 mg/day oraly) and placebo. The two groups will be randomaized into two subgroups: exercise group (aerobic trainning,cicle-ergometre, 50 minutes, 3 x week) and sedentary group. At 0, 6 and 12 months the volunteers will be submited to: clinical analise, cardiorespiratory analise (ergoepirometric test), quality of life questionare (Short Form-36 [SF-36]), ambulatory blood pressure monitoring during 24 hours and to 2 experimental sessions where the cardiovascular responses to insulin action (euglicemic/hiperinsulinemic clamp) and to physical and mental stress (microneurography) will be accessed. Besides these, the volunteers of the sedentary group will be submited to an extra session at 6 months of study evaluate the physiological answer to insulin infusion after an acute session of exercise.
