Extreme Endurance Exercise: If You Do This Type of Exercise, You Could Be Damaging Your Heart

Story at-a-glance -

  • Several recent scientific studies indicate that endurance exercises, such as marathon and triathlon training, pose significant risks to your heart, some of which may be irreversible and life threatening
  • Long-distance running can lead to acute volume overload, inflammation, thickening and stiffening of the heart muscle and arteries, coronary artery calcification, arrhythmias and sudden cardiac arrest
  • A safer and more effective exercise is high intensity interval training (HIIT), which consists of short bursts of intense exertion; HIIT maximizes the benefits for your heart, and optimizes your HGH and insulin levels
  • Keep your intense workouts to less than 45 minutes, and if you run, keep your distance under 20 miles per week spread over two to three days, at five miles per hour or less, to minimize risks and maximize benefits
  • Allowing your body to fully recover between workouts is critical, including eating an appropriate post-workout meal that gives your body the nutrients it needs to recover and rebuild
