Conditions

Hypertension

Interventions

Experimental groups: 25 hypertensive men will perform 5 experimental sessions composed by a exercise on cyclergometer (30 minutes, intensity of 70% of the VO2peak workload) and 5 recovery protocols: a
b) active recovery
c) assisted recovery
d) occlusion recovery
e) recovery with cooling. In addition, 25 normotensive men will perform the same interventions and will be considered the control group of this study.

Eligibility

Sex/Gender
Male
Age
40 Years to 60 Years

Inclusion criteria

Inclusion criteria: Men. Aged between 40 and 60 years. Non smokers. Physically inactives (did not perform physical activity more than twice a week). Normotensives and hypertensives will form different groups. Hypertensives should not have end organ damage or secondary causes of hypertension according to the diagnotic rotine of the Hypertension League of Clinical Hospital, Faculty of Medicine, USP.

Exclusion criteria

Exclusion criteria: Subjects with obesity level 2 or greater(body mass index equal or greater than 35 kg/m2). Subjects with diabetes (fasting glycemia equal or greater than 126 mg/dl). Subjects with cardiac diseases (previous diagnosis or alteration on resting or exercise ECG). Use of anti-hypertensive medication.

Design outcomes

Primary

MeasureTime frame
Reduced heart rate recovery in the sessions "active", "assisted" and "with occlusion" and increased in the sessions "inactive" and "with cooling"; demonstrating the effects of the cardiovascular control mechanisms in the regulation of heart rate recovery after exercise—

Secondary

MeasureTime frame
Reduced heart rate recovery in hypertensive group in comparison to normotensive due to dysfunction of one or several cardiovascular control mechanisms—
