Athlete's Heart: When Fitness Puts Your Heart Under Strain
12 May
Summary
- Intensive exercise can cause structural heart changes, termed 'athlete's heart'.
- The heart muscle, like skeletal muscles, can thicken due to prolonged exertion.
- This thickening may lead to a smaller left ventricle cavity and reduced filling.
Intensive physical training can lead to significant structural changes in the heart, a condition known as 'athlete's heart.' This phenomenon occurs as the heart muscle adapts to sustained exertion, similar to how skeletal muscles hypertrophy.
Cardiologists explain that prolonged and demanding exercise causes the heart muscle, particularly the left ventricle, to thicken. This adaptation may consequently lead to a slight decrease in the left ventricular cavity's size.
Such changes can result in a mildly reduced capacity for the left ventricle to fill with blood. While appearing fit, individuals engaging in extreme exercise routines should be aware of these potential physiological responses within their cardiovascular system.
