Background:Cardiovascular diseases (CVDs) remain the leading cause of mortality worldwide. Physical activity is recognized as one of the most effective and cost-efficient interventions for preventing and managing cardiovascular diseases. Regular exercise improves cardiac function, blood pressure regulation, lipid metabolism, vascular health, and overall cardiovascular fitness.Objective:To evaluate the impact of physical activity on cardiovascular health indicators among adults and to identify the relationship between exercise frequency and cardiovascular risk reduction.Methods:A cross-sectional observational study was conducted among 650 adults aged 25–70 years. Participants were categorized according to physical activity levels using the International Physical Activity Questionnaire (IPAQ). Cardiovascular health indicators including blood pressure, resting heart rate, body mass index (BMI), lipid profile, and cardiovascular risk scores were assessed. Statistical analyses included descriptive statistics, chi-square tests, ANOVA, and multivariate regression analysis.Results:Participants engaging in regular moderate-to-vigorous physical activity demonstrated significantly lower systolic blood pressure, resting heart rate, LDL cholesterol levels, and cardiovascular risk scores compared to sedentary individuals (p < 0.001). Regular exercise was associated with a 38% reduction in cardiovascular disease risk.Conclusion:Physical activity significantly improves cardiovascular health and reduces cardiovascular risk factors. Promotion of regular physical activity should remain a cornerstone of public health strategies aimed at preventing cardiovascular diseases.
Cardiovascular diseases account for nearly one-third of global deaths annually and represent a major public health challenge. Major cardiovascular conditions include:
Lifestyle modifications are increasingly recognized as essential tools for cardiovascular disease prevention.
Physical activity refers to any bodily movement produced by skeletal muscles that results in energy expenditure. Regular exercise contributes to improved cardiovascular performance through multiple physiological mechanisms.
Benefits include:
Despite well-established benefits, physical inactivity remains highly prevalent worldwide and contributes significantly to cardiovascular morbidity and mortality.
Numerous studies have established a strong inverse relationship between physical activity and cardiovascular disease.
Research findings indicate:
The World Health Organization recommends at least 150–300 minutes of moderate-intensity physical activity per week for adults.

This study demonstrates that regular physical activity significantly improves cardiovascular health outcomes. Participants engaging in moderate and high levels of exercise showed lower blood pressure, healthier lipid profiles, lower BMI, and reduced cardiovascular risk scores.
Physical activity enhances cardiovascular function through several mechanisms:
Individuals with higher activity levels exhibited lower LDL cholesterol and higher HDL cholesterol concentrations, reducing atherosclerotic risk.
The findings support previous studies demonstrating that exercise serves as both a preventive and therapeutic intervention for cardiovascular disease.
Increasing physical activity levels across populations may result in:
Community-based interventions promoting exercise can substantially improve population cardiovascular health.

Strengths
Limitations
Future investigations should focus on:
Physical activity is a powerful determinant of cardiovascular health. Regular participation in moderate-to-vigorous exercise significantly improves blood pressure control, lipid profiles, body composition, and overall cardiovascular risk. Individuals with higher physical activity levels experience substantially lower risks of cardiovascular disease compared with sedentary individuals. Public health policies and clinical interventions should prioritize physical activity promotion as a fundamental strategy for cardiovascular disease prevention and health promotion.
