In older adults, greater leisure-time physical activity and better chair-stand physical fitness are associated with reduced leukocyte telomere length attrition over time.
For older adults, focusing on increasing leisure-time activity (like walking, gardening, or hobbies) and improving functional fitness (like the ability to stand up from a chair quickly) may help slow cellular aging. You don't need intense gym workouts; consistent, moderate leisure activity and maintaining functional strength are key metrics linked to healthier telomere dynamics.
changes in leisure-time activity and chair test performance were each inversely associated with changes in TL... suggesting that leisure-time activity and fitness could reduce leukocyte telomere attrition among older adults.
Why this rating
Large prospective cohort with repeated measures, but observational design limits causal inference; p-values are borderline (0.04-0.07).

- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
