It’s been a week since Raju Srivastava, the laughter king, died of a heart attack. He apparently fainted while working out in a gym on the treadmill.
A year ago, the same thing happened to Kannada sensation Puneeth Rajkumar. He collapsed after suffering a major heart arrest while working out in a Bengaluru gym.
Puneeth Rajkumar’s elder brother, Kannada actor Shiva Rajkumar, fell in the gym while working out in 2015 and suffered a small heart attack. He was fortunate to survive.
Not just them, but a great number of performers and athletes have been known to suffer from cardiac arrest as a result of excessive exertion. As we all know, too much of anything is bad.
Workouts are no exception. Excessive high-intensity exercise has been shown to increase the chance of having a heart attack and developing heart arrhythmia or abnormal heart rhythm later in life.
Those who have inherited heart abnormalities are particularly prone to cardiac arrests caused by strenuous activity.
Finding the link between excessive exercise and heart health
While moderate exercise improves heart health, long-term endurance exercise can place additional strain on the cardiovascular system.
Excessive activity frequently results in the production of biomarkers in the blood that may be linked to heart injury.
While these biomarkers can disappear on their own, when vigorous exercise is repeated, this transient damage might culminate in heart remodelling or physical changes such as thickening of the heart walls and harm to the heart.
Also, it has been observed that high intensity exercise can significantly increase the risk for sudden cardiac arrests and even fatality due to cardiac arrest among those with an underlying cardiac condition.
Additionally, it can increase the risk of heart rhythm disorders, especially for those who suffer from hypertrophic cardiomyopathy – a condition in which heart muscles become abnormally thick and coronary heart disease – damage or disease in the heart’s major blood vessels.
Strenuous exercise for a prolonged period of time is known to enhance the chance of developing atrial fibrillation – an irregular, often rapid heart rate that commonly causes poor blood flow.
How much exercise is too much for the heart
150 minutes of moderate intensity activity a week is a healthy recommendation for the heart. Anything beyond that like running about 60 to 80 miles every week could be damaging for the heart.
Running long distances on pavement or any kind of vigorous exercise that one hasn’t trained for could be injurious to your heart. Also, a high -intensity exercise could be harmful for heart health if one does it without warming up.
