New Study: Regular Exercise Slashes Heart Disease Risk by 50%
A new study emphasizes the lifesaving benefits of exercise for heart health. It demonstrates that regular physical activity can significantly decrease the risk of heart disease and death. The findings highlight the importance of incorporating exercise into daily life.
The research, published in the American Heart Association journal Circulation, reveals that heart attack patients who participate in formal exercise programs can reduce their mortality rate by 20-25%. This is a significant reduction, given that inactivity is one of the top five risk factors for heart disease, contributing to around 250,000 deaths annually in the U.S.
Physically active individuals have a 50% lower risk of coronary artery disease compared to sedentary people. Regular exercise keeps arteries and blood vessels flexible, ensuring good blood flow and normal blood pressure. It also reduces the risk of heart failure and improves the heart's ability to pump blood, increasing peak cardiac output by over 20%.
Men who spend more than 23 hours a week being sedentary have a 64% greater risk of dying from heart disease than those who spend less than 11 hours. Exercise helps control blood pressure by stimulating the production of nitric oxide, which keeps blood vessels open. Regular brisk walks can raise HDL (good) cholesterol levels, reducing the risk of coronary events by over 50%.
The study suggests engaging in endurance and strength training about 3 to 5 times per week for 20 to 45 minutes each session, exercising at 60-70% of one's heart rate reserve. This helps minimize the risk of heart disease without overloading the body. It's crucial that training is done under pulse control and only by clinically stable individuals, avoiding contraindications such as unstable heart conditions or untreated hypertension.
The study underscores the crucial role of regular exercise in preventing and managing heart disease. By incorporating physical activity into our daily lives, we can significantly reduce our risk of heart disease and improve overall health. It's a powerful reminder that taking care of our hearts starts with moving more.
