Regular physical activity or exercise reduces all-cause mortality by approximately 13% compared to control groups, with the magnitude of benefit being larger for patients with cardiovascular disease than for other populations.
To reduce your risk of death, aim for at least 150 minutes of moderate-intensity aerobic activity per week (or 75 minutes of vigorous activity). You do not need to do extreme amounts of exercise to see benefits; simply meeting these minimums significantly lowers mortality risk, especially if you have cardiovascular issues.
Based on 10 CSRs and 187 RCTs with 27,671 participants, there was a 13% reduction in mortality rates risk ratio (RR) 0.87 [95% confidence intervals (CI) 0.78 to 0.96]... This reduction was smaller in ‘other groups’ of patients when compared to cardiovascular diseases (CVD) patients - RR 0.97 [95% CI 0.65, 1.45] versus 0.85 [0.76, 0.96] respectively.
Why this rating
Based on 10 Cochrane Systematic Reviews and 187 RCTs, though heterogeneity exists, the evidence quality is generally high.
