Relationship between Physical Activity Level, Telomere Length, and Telomerase Activity.

The article cites a study which examines the relationship of exercise energy expenditure (EEE) with both telomere length and telomerase activity. The study involves 69 participants 50-70 year who were assessed for weekly EEE level using the Yale Physical Activity Survey. It is revealed that the second EEE quartertile exhibited significantly longer telomere lengths than both the first and fourth EEE quartertiles, but was not different from the third quartertile. It is concluded that moderate physical activity levels provides a protective effect on peripheral blood mononuclear cells (PBMC) telomere length compared with both low and high EEE levels.
