Sixteen Weeks of Resistance Training in Hypertensive Elderly, Effects on Heart Rate Variability

Not Applicable

Completed

• Conditions: Hypertension
• Interventions: Behavioral: Resistance training

• Registration Number: NCT03254225
• Lead Sponsor: Federal University of São Paulo

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.

Arm && Interventions

Group	Intervention	Description
Resistance training	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).
