Physical effort, for example, increased people's chance of having a heart attack, whether they were generally sedentary or exercised on a regular basis. Nonetheless, the researchers stated that people experience "external stressors" such as anger and exercise on a daily basis without succumbing to a heart attack. They concluded that other factors are likely responsible for causing heart disease.
In addition to external stressors, physical exertion also causes internal stress. As we exercise, our hearts work harder to deliver blood to working muscles. This increased demand on the heart leads to fatigue, especially in individuals who may not be used to strenuous activity. Repeated episodes of cardiac fatigue can result in damage to the heart muscle, which can lead to heart failure.
Studies have shown that people who walk regularly experience less risk of heart disease than those who do not walk at all. Even more impressive is the fact that those who exercise vigorously every week are still protected by this association. It appears that the more you exercise, the better it is for your heart health.
Exercise is important for maintaining good health. It reduces your risk of developing diseases such as diabetes, high blood pressure, and obesity. Exercise also helps keep your weight under control by using up stored energy in your body through sweat. A reduced need for storing energy along with decreased abdominal fat means you're burning calories at a faster rate.
Physical exercise decreases the risk of coronary heart disease events, however strenuous activity can potentially raise the risk of sudden cardiac death and acute myocardial infarction in vulnerable patients. The risk of a cardiac event increases with the intensity and duration of the exercise.
In otherwise healthy individuals, the risk of suffering a cardiac event during exercise is low but it should not be ignored due to its potential consequences. Patients who suffer a cardiac event while exercising should rest until their condition stabilizes before continuing with their regular activities. If at any time they experience symptoms such as chest pain or shortness of breath, they should seek medical attention immediately.
Patients who are considered to be at high risk for a cardiac event should not engage in intense physical activity. They should perform moderate-intensity sports that do not cause undue fatigue and are activities that they enjoy. High-risk patients should also follow up with their physicians before beginning an exercise program.
Cardiac rehabilitation is a supervised program designed to reduce the risk of cardiac events by promoting a healthier lifestyle. The goals of cardiac rehabilitation include improving cardiovascular health, reducing the risk of future cardiac episodes, and enhancing quality of life. Cardiac rehabilitation typically includes exercise training as part of its core components. Other aspects may include education programs, nutritional counseling, and psychological support.
How can physical inactivity contribute to an increased risk of heart and circulatory diseases? Inactivity might cause fatty material to accumulate in your arteries (the blood vessels that carry blood to your organs). A heart attack can occur if the arteries that deliver blood to your heart become damaged and blocked. As we have seen, being inactive is likely to increase your risk of developing conditions such as diabetes and high blood pressure, which are also factors in increasing your chances of having a stroke or some form of cardiac arrest.
The American Heart Association recommends that adults should try to exercise for at least 30 minutes a day, five days a week. If you are already active, you may be able to increase that amount to 45 minutes per day.
If you do not exercise now, start by adding some activity into your daily life. You do not need to run a marathon, just take the time to walk or stretch during your lunch break. Over time you will see improvements in how you feel and function if you are currently inactive.
In conclusion, physical inactivity is one of the most important contributors to the development of cardiovascular disease. Exercise is beneficial for everyone, no matter your age or health status. It will help you maintain a healthy weight, reduce your risk of developing other illnesses such as diabetes and improve your quality of life.
