Study Overview
Brief Summary
This study evaluates the inffluence of 16 weeks of resistance training on heart rate variability of hypertensive elderlies patients. All volunteers will be divided in two groups, one will participate in a protocol of sixteen weeks of resistance training, an the other will remain sedentary.
Detailed Description
This study evaluates the inffluence of 16 weeks of resistance training on heart rate variability using time and frequency-domains by ECG tracks. Will be assessed the blood pressure using the ambulatory blood pressure monitoring method of hypertensive elderly patients. All volunteers will be divided in two groups, one will participate in a protocol of sixteen weeks of resistance training prescribed with a relative workload of 50% of 1 maximal repetition, an the ontrol group will remain sedentary.

Arms & Interventions
Resistance training
Resistance training performed three times at week for 16 weeks, in 8 exercises for the main muscles, the protocol of 3 sets of 10 repetitions with intensity of 50% of 1 maximum repetition (MR).
Intervention: Resistance training (Behavioral)
Control
in this arm, the group will remain sedentary for the same period of the experimental group, and they will be invited to engage on the raining program after the sedentary period
Outcomes
Primary Outcomes
Blood pressure change due to resistance training
Time Frame: 16 weeks
Blood pressure will be measured by Ambulatorial Monitoring Blood Pressure before and after 16 weeks of intervention.
Secondary Outcomes
- Heart rate variability - Time domain - change due to resistance training(16 weeks)
- Heart rate variability - Frequency domain - change due to resistance training(16 weeks)
- Heart rate variability - Non-linear methods - change due to resistance training(16 weeks)
