The key is that these activities raise your heart rate and breathing rate for a sustained period, causing the heart to pump more blood with each beat and reducing its overall workload at rest .
The Science Behind the Benefit
Study after study has shown that aerobic physical activity is superior to other forms of exercise when it comes to lowering heart attack risk . Here’s why:
It directly targets the cardiovascular system. Aerobic exercise trains the heart muscle itself, improving its ability to pump blood and oxygen to the rest of the body. Over time, this reduces the heart’s workload at rest and makes it more resilient under stress .
It lowers blood pressure. High blood pressure is one of the leading risk factors for heart attack. Regular aerobic exercise has been shown to lower blood pressure in both healthy individuals and those with hypertension .
It improves cholesterol profiles. Cardio increases “good” HDL cholesterol and helps reduce “bad” LDL cholesterol, reducing the buildup of plaque in the arteries that can lead to a heart attack .
It reduces coronary heart disease risk. Coronary heart disease, where plaque clogs the arteries and reduces blood flow to the heart muscle, is the most common cause of heart attacks. Aerobic exercise directly combats this process .
It strengthens blood vessels. Regular cardio improves the health and flexibility of blood vessels, supporting healthy circulation and reducing the risk of blockages .
