Engaging in total physical activity of at least 4200 kJ/wk (approx. 1000 kcal/wk) reduces the risk of coronary heart disease by approximately 20% in middle-aged and older men, with the strongest risk reductions associated with vigorous-intensity activities.
To significantly lower your risk of heart disease, aim to burn at least 1,000 calories per week through physical activity. You don't need to run marathons; brisk walking, swimming, or yard work for about 30 minutes a day, most days of the week, is sufficient. If you can incorporate more vigorous sports, the benefit is even greater, but moderate activity alone is highly effective.
Total physical activity and vigorous activities showed the strongest reductions in CHD risk... men expending $4200 kJ/wk had reduced CHD risk compared with men expending ,4200 kJ/wk.
Why this rating
Large cohort (n=12,516), long follow-up (1977-1993), multivariate adjustment for major risk factors, though reliance on self-reported activity introduces potential misclassification bias.

- Vigorous physical activity (≥6 METs) is independently associated with a reduced risk of coronary heart disease, whereas the benefits of moderate and light activities are less clear or non-significant in multivariate models.Good
- Physical activity reduces coronary heart disease risk even in men with multiple existing coronary risk factors (such as smoking, hypertension, diabetes, or high BMI).Good
