Excessive exercise hurts the heart? Know the dangers of overtraining

Excessive exercise hurts the heart? Know the dangers of overtraining

The athlete's heart is a term used in cardiology to comprehensively describe all changes in the shape and functioning of the heart of well-trained athletes.

When a subject is submitted to any repetitive activity two things happen: wear and tear. Wear may be more easily seen by joint pain in the knees of runners or elbows of tennis players and golfers. This can be prevented by avoiding abuse and by using adequate protection of the limbs. Adaptation is more readily observed in muscle hypertrophy in weight lifters and in the rearrangement of bone fibrous tracts to support better impact during growth.

The heart, like the muscle it is, also undergoes adaptation when subjected to repeated stress. > The most common changes are:

Reduced heart rate: signs that the parasympathetic autonomic nervous system has become accustomed to the adrenaline overload and has learned to balance heart rate and its deleterious effects

  • Myocardial hypertrophy: muscle increases its mass to improve performance and adapt to high flow during sport
  • Winds: can be caused by hypertrophy, more rarely, or by increased flow. They should be evaluated carefully because their presence may not be benign.
  • Cardiac arrhythmias: adaptation is already beginning to become wear and tear. The heart under intense stress may no longer tolerate exertion and may create premature beats or more severe arrhythmias. These should be warning signs for deconditioning or further investigation.
  • Concern for the athlete's heart comes from the characteristics in common between this and a serious condition called hypertrophic cardiomyopathy, which is a genetic disorder that causes the hypertrophic muscle even without need. It is a relatively common disease in the general population, and the patients are at high risk of death if they undergo strenuous physical activity. It is believed that most athletes who die suddenly during physical activity have some genetic disease (such as hypertrophic cardiomyopathy or long QT syndrome) that may have been identified in routine exams such as an ECG or echocardiogram. possible (and necessary) to ward off heart disease before beginning to perform high-performance activities. Medical consultation is a time spent that can save you a lot of inconvenience in the future!

Best Triceps Exercises

The brachial triceps, famously known as the bye muscle, is the musculature responsible for elbow extension. It is the largest arm muscle, with a 60% total mass share of this limb and is located on its posterior face. In daily activities, we need the triceps muscles whenever there is an elbow extension: when tightening a screw , painting a wall, washing the hair, putting on the shoe.
