About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Hypertensives
  • Age 60 to 80 years
  • Nonactive

  • Absence in more than 25% of the exercise sessions

Treatment and study plan

Resistance training

Behavioral

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).

Primary outcomes

  1. 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

  1. Heart rate variability - Time domain - change due to resistance training

    Time frame: 16 weeks

    Heart rate variability will be collected by electrocardiogram before and after 16 weeks of intervention

  2. Heart rate variability - Frequency domain - change due to resistance training

    Time frame: 16 weeks

    Heart rate variability will be collected by electrocardiogram before and after 16 weeks of intervention

  3. Heart rate variability - Non-linear methods - change due to resistance training

    Time frame: 16 weeks

    Heart rate variability will be collected by electrocardiogram before and after 16 weeks of intervention
