Background:
This study aimed to evaluate the effect of physical exercise on the physical and mental health of older adults using meta-analysis and to analyze the moderating variables influencing this relationship. The goal was to provide a scientific basis for identifying effective exercise methods to enhance the physical and mental health of the older adults.
Methods:
A literature search was conducted in databases such as PubMed, Web of Science, Cochrane Library, and Google Scholar. Data were processed using Review Manager 5.4 and Stata 18.0 statistical software. Meta-analysis was performed using the random effects model, and relevant moderating variables were tested.
Results:
The study findings indicated that physical activity significantly improves the physical and mental health of older adults across various dimensions. Specifically, it showed a large effect size for enhancing social interactions (standardized mean difference (SMD) = 0.78, 95% confidence interval (CI) [0.14, 0.69], P = 0.0002), a medium effect size for improving physical health (SMD = 0.42, 95% CI [0.20, 0.48], P = 0.003), and a small effect size for improving mental health (SMD=0.34, 95% CI [0.37, 1.19], P < 0.001). All differences were statistically significant.
Conclusion:
Physical exercise has a positive impact on improving the physical and mental health of older adults, particularly in enhancing physical health, psychological well-being, and social interactions.

01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

The Role of Exercise in Stress Management
Regular physical activity is essential for reducing stress and promoting cardiovascular health. Exercise strengthens the heart, enhances blood flow, keeps blood vessels flexible, and helps lower blood pressure, all of which reduce the body's stress response. Research shows that adults who exercise regularly have nearly half the...
