Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Different classes of antihypertensives may have different responses when associated with exercise. Thus, this study aims to compare the responses of the association of 12 weeks of aerobic exercise and weightlifting with different classes of medications in 45 postmenopausal hypertensive women.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Cardiovascular diseases are the leading causes of death and postmenopausal women. Physical exercise, in turn, is a strategy to reduce cardiovascular stress, by decreasing the blood pressure (BP) at rest and several risk factors associated with sedentary lifestyle, thus improving the quality and life expectancy of these women. However, different classes of antihypertensives may have different responses when associated with exercise. Thus, this study aims to compare the responses of the association of 12 weeks of aerobic exercise and weightlifting with different classes of medications in 45 postmenopausal hypertensive women. The volunteers will do cardiovascular and biochemistry evaluations before and after the intervention.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

No medication

Group of pre-hypertensive women with no medication who practiced 12 weeks of training with Combined Exercise Training, non-obese, nonsmokers and with no characteristics that prevented them from performing the activities. In addition this group could not modify the dose or type of the medicine and should be using the same medicine and dose for at least 6 months

Group Type PLACEBO_COMPARATOR

Combined exercise

Intervention Type OTHER

The program consisted of 36 sessions of combined aerobic and resistance exercises training during 12 consecutive weeks. Each session lasted 60 minutes and consisted of 30 minutes of resistance exercise and 30 minutes of aerobic exercise. The resistance training was performed in two sets of 8 to 12 repetitions in five exercises of weight training (Based on 1 repetition maximum test - 1RM). The aerobic exercise was performed on a treadmill, at a speed of 5.5 km/h and intensity (imposed by treadmill inclination and heart rate) between 65 and 75% of maximun heart rate measured in maximum incremental test. Every week the resistance load and aerobic intensity was readjusted by determined training zone (8 to 12 maximum repetitions) and heart rate predicted in the incremental respectively.

Angiotensin receptor blockers

Group of hypertensive women taking Angiotensin receptor blockers who practiced 12 weeks of training with Combined Exercise Training, non-obese, nonsmokers and with no characteristics that prevented them from performing the activities. In addition this group could not modify the dose or type of the medicine and should be using the same medicine and dose for at least 6 months

Group Type ACTIVE_COMPARATOR

Combined exercise

Intervention Type OTHER

The program consisted of 36 sessions of combined aerobic and resistance exercises training during 12 consecutive weeks. Each session lasted 60 minutes and consisted of 30 minutes of resistance exercise and 30 minutes of aerobic exercise. The resistance training was performed in two sets of 8 to 12 repetitions in five exercises of weight training (Based on 1 repetition maximum test - 1RM). The aerobic exercise was performed on a treadmill, at a speed of 5.5 km/h and intensity (imposed by treadmill inclination and heart rate) between 65 and 75% of maximun heart rate measured in maximum incremental test. Every week the resistance load and aerobic intensity was readjusted by determined training zone (8 to 12 maximum repetitions) and heart rate predicted in the incremental respectively.

Beta blockers

Group of hypertensive women taking Beta blockers who practiced 12 weeks of training with Combined Exercise Training, non-obese, nonsmokers and with no characteristics that prevented them from performing the activities. In addition this group could not modify the dose or type of the medicine and should be using the same medicine and dose for at least 6 months
