Stretching Versus Walking From Reducing Blood Pressure

Hypertension Clinical Trial

Official title: Comparison of Stretching and Walking as Exercise Modalities for Reducing Blood Pressure

Status Completed

Clinical Trial Summary

High blood pressure is a leading risk factor for cardiovascular disease. Traditionally, one of the ways to treat or prevent high blood pressure is to prescribe aerobic exercise training (i.e.brisk walking). Previous studies have shown that stretching is also very effective for reducing blood pressure. This is an exciting possibility because if stretching is more effective, it would change the way exercise is prescribed to people with elevated blood pressure. This study will now assess 20 individuals in a supervised stretching or walking program five days per week for 8 weeks to determine for certain whether stretching is superior for reducing blood pressure. This research will contribute to recommendations about the most effective exercise programs for reducing blood pressure and risk of cardiovascular disease.

Clinical Trial Description

The study hypothesis is that stretching (flexibility training) will be superior to brisk walking for reducing blood pressure. This is a parallel-group randomised trial. Twenty participants (aged 18 and older) with borderline or stage-1 hypertension (systolic blood pressure between 130 and 159 mmHg OR diastolic blood pressure between 85 and 99 mmHg) will be randomised to walking or stretching groups. Each group will do 30 minutes of exercise, five days per week. Exercise sessions will be supervised three days per week with participants doing exercise sessions on their own two days per week. Exercise sessions involve either brisk walking or stretching. The stretching exercises will involve stretching all major muscle groups. The main outcome is 24-hour blood pressure which will be assessed at baseline, after four weeks, and after eight weeks. Other outcomes will be assessed at baseline and eight weeks and include: Body weight, height, waist circumference, resting heart rate, physical activity levels (questionnaire), diet (questionnaire), maximal distance walked in six minutes. All participants will be counselled on how to follow the DASH eating plan, which involves reducing dietary salt intake. Statistical analyses: All outcomes will be assessed with a group x time ANOVA with alpha level of 0.05. LSD post-hoc tests will be done when necessary to identify differences between pairs of means. ;
