Summary
This study found that endurance athletes diagnosed with fatigued athlete myopathic syndrome had shorter telomeres in their muscles cells than controls. This study is intriguing because it hints at the long term implications of intense training over long periods of time. Intense exercise incurs high oxidative stress loads and the repetitive injury to muscle requires high levels of cellular replication – both of these conditions are primary contributors to telomere attrition.
