Aerobic Endurance Training

Aerobic endurance training shows a significant positive association with increased telomere length. Cardiac arrhythmias caused by endurance exercise are reversible with proper knowledge and adjustments to training. Standard short aerobic exercise without an endurance component does not show a significant association with telomere length. The problem stems specifically from the sustained nature of endurance exercise, which works against the body's natural rhythms. Sustained endurance exercise performed for over one hour per day, five days a week creates structural and functional changes in the heart. Anything sustained at high intensity is extremely stressful on the body. Aerobic endurance training involves sustained aerobic effort over a longer period, distinguishing it from short-duration aerobic exercise. Cutting back on exercise volume is the primary recommendation for athletes experiencing extra beats or arrhythmias.
