What is the current evidence regarding the relationship between telomere shortening and exercise??
Dear Exal,
This recent review by Arsenis et al. gives a good overview:

Best wishes from Germany,
Martin
Here's another recent study on the question:

I don't know the answer. However, if exercise is a component of well being and overall health. My sense it would lengthen the telomere.
Hi everybody,
If telomere length is positively influenced by healthy living, it implies that besides physical activity, diets also play greater roles in controlling oxidative stress and telomere tength. Balanced diets full of colored vegetables & fruits (polyphenols) and limiting carbs with avoidance of simple sugars, and processed foods help reduce oxidative stress, to encourage mitogenesis and telomere lengthening.
