Objectives: a. The determination of the efficacy of physical activity in reducing the risk of cardiovascular disease; b. The Analysis of the relative changes in the levels of cardiovascular disease risk according to different intensities of physical activity (low-moderate). Methodology: The search was performed for studies with PUBMED data base. Then, the mean effect size of the studies included in the meta-analysis was calculated and Egger's test was applied to rule out any possible publication bias. Upon detection of heterogeneity, we proceeded to an analysis of the moderating variables. Results: A mean effect size of 0.762 (95% confidence interval 0678-0857) was obtained. Then The Egger test was applied which yielded a p-value of 0.67 (CI 0.95), such that the absence of publication bias was confirmed. The analysis of the moderating variables determined that the ensuing years (p = 0.000, 95% CI) and the countries of study (p = 0.0096; 95% CI) in part explain the heterogeneity detected. Conclusion: It can be concluded that the practice of physical activity at moderate intensities provides a protective effect on the individuals who make physical activity by reducing the risk these individuals to cardiovascular diseases.
