2401 caucasion twin pairs
Summary
The leukocyte telomere lengths of the most active subjects were 200 nucleotides longer than those of the least active subjects. This finding was confirmed in a small group of twin pairs with different levels of physical activity. This study suggests that physical activity during leisure time is associated with longer telomeres.
