AI Insight
An observational study published in the British Journal of Sports Medicine suggests that adults may need between 560 and 610 minutes of moderate to vigorous physical activity per week to achieve a substantial reduction in cardiovascular risk, including heart attacks and stroke. This figure significantly exceeds current public health guidelines, which typically recommend around 150 minutes of moderate activity per week. The findings indicate that the widely promoted exercise thresholds may be insufficient for optimal heart protection.
Why it matters
If confirmed by further research, these findings could prompt a major revision of global physical activity guidelines, with significant implications for public health messaging and preventive cardiology. It also raises questions about the feasibility of recommended targets for the general population.
Adults should aim to do between 560 and 610 minutes a week of moderate to vigorous physical activity to achieve a substantial reduction in the risk of heart attacks and stroke, suggest the findings of an observational study published in the British Journal of Sports Medicine.
