Summary
A low-intensity exercise program significantly enhanced dynamic balance and lower body strength in older adults from disadvantaged communities. Blood pressure also improved, especially in hypertensive individuals, demonstrating the program's effectiveness.
Area of Science:
- Gerontology
- Community Health
- Exercise Science
Background:
- Older adults in socio-economically disadvantaged communities often face barriers to physical activity.
- Low-intensity exercise programs can be a viable option to improve health outcomes in this population.
Purpose of the Study:
- To evaluate the effectiveness of a community-based, low-intensity exercise program for older adults in disadvantaged communities.
- To assess improvements in physical function, blood pressure, and health status.
Main Methods:
- A 20-week, twice-weekly exercise program was implemented in two community centers (EX1, EX2).
- A third center served as a control group (CTL) engaging in relaxation classes.
- Measurements included anthropometry, balance, strength, gait, blood pressure, ADL, IADL, and self-perceived health.
Main Results:
- Significant improvements in dynamic balance and lower body strength (sit-to-stand) were observed in both exercise groups compared to the control.
- Systolic blood pressure decreased significantly in exercise groups, particularly in hypertensive participants.
- No significant changes were noted in upper body strength, body composition, gait speed, or self-perceived health.
Conclusions:
- Community-based, low-intensity exercise is effective in improving dynamic balance and lower body strength in older adults.
- The program positively impacts blood pressure, offering benefits especially for hypertensive individuals.
- This intervention demonstrates potential for improving physical function and cardiovascular health in underserved older populations.
