In fact, according to a study published in the journal "Circulation," it's estimated that less than 1% of all sudden cardiac deaths occur in young athletes. This does not mean that extreme exercise is without risks. Excessive exercise can lead to Arrhythmias( Arrhythmias are heart rhythm problems. They can affect the heart’s normal rhythm or the rhythm of the heart after it has been stimulated by a stimulus, such as an exercise.
Arrhythmias can cause chest pain, shortness of breath and fainting ), Electrolyte abnormalities ( Electrolyte abnormalities are common in hospitalized patients. Electrolytes are minerals and salts that are essential for normal nerve function and muscle function. The most common electrolyte abnormalities are low levels of potassium, chloride, and sodium.
Low levels of potassium can cause abnormal heart rhythms, while low levels of sodium can cause fluid retention and heart failure), and Cardiomyopathies (are a group of diseases that affect the heart muscle. They can cause chest pain, shortness of breath, and problems with the heart’s rhythm. There are a number of different cardiomyopathies, and each one is caused by a different problem with the heart muscle.
Some of the most common cardiomyopathies are dilated cardiomyopathy, hypertrophic cardiomyopathy, and arrhythmogenic right ventricular cardiomyopathy), all of which can be potentially fatal. Therefore, it's important to consult with a doctor before starting any extreme exercise regimen.
