Summary
Long-term aerobic exercise significantly lowers blood pressure (BP) both at rest and during physical activity in individuals with hypertension. This beneficial effect, comparable to drug therapies, can be sustained for at least three years.
Area of Science:
- Cardiovascular Health
- Exercise Physiology
- Hypertension Management
Background:
- Cardiovascular health is significantly influenced by blood pressure (BP) control.
- Effective BP management is crucial for cardiovascular disease prevention.
- The long-term impact of exercise as a sole treatment for BP remains understudied.
Purpose of the Study:
- To investigate the long-term effects of regular aerobic training on resting and exercise blood pressure in hypertensive individuals.
- To assess the sustained impact of exercise monotherapy on blood pressure control.
Main Methods:
- Ten hypertensive subjects (mean age 43 years) participated in the study.
- Subjects engaged in supervised aerobic exercise (2 sessions/week, 60 minutes each).
- Blood pressure was measured at rest and during graded ergometry (50-100 W) before and after training periods.
Main Results:
- Aerobic training led to a significant reduction in BP at rest and during exercise.
- After 18 months, resting BP decreased, and exercise BP at 100 W showed significant reductions (P < 0.001).
- A 3-year follow-up confirmed sustained BP reduction, with no significant changes in body weight.
Conclusions:
- Long-term aerobic exercise effectively lowers blood pressure at rest and during exertion.
- The antihypertensive effects of exercise are comparable to pharmacological interventions.
- Regular training provides a sustained, long-term benefit for blood pressure management in hypertensive patients.
