The ‘U-shaped’ correlation between physical activity and the risk of heart attacks has been elucidated. Engaging in moderate aerobic exercise for a minimum of 150 minutes weekly, or participating in vigorous aerobic activities for at least 75 minutes weekly, can significantly reduce the likelihood of mortality.
Exercise serves as an economical and effective means to manage, prevent, or mitigate the risk of cardiovascular disease in individuals. In a discussion with Raj Shamani, Dr. Ravinder Singh Rao, an interventional cardiologist, emphasized the U-shaped relationship between exercise and heart health. In essence, while moderate exercise is preferable to a sedentary lifestyle, excessive exercise may pose risks for certain individuals. Dr. Rao stated, “We must practice moderation, as extreme physical activity is linked to an increased risk of heart attacks.”
The U-shaped curve, often referred to as the extreme exercise hypothesis, illustrates the relationship between physical activity levels and cardiovascular health outcomes. Dr. Haresh G. Mehta, director of interventional cardiology at S L Raheja Hospital in Mahim, explained, “This curve indicates that engaging in low to moderate physical activity significantly lowers the risk of cardiovascular disease and mortality, whereas very high levels of exercise may elevate these risks.”
