What is the relationship between physical activity and telomere length?

Physical activity has been shown to have a positive effect on telomere length. Studies have found that individuals who engage in regular physical activity have longer telomeres compared to those who lead a sedentary lifestyle. This is likely due to the fact that physical activity promotes overall health and reduces oxidative stress, which can contribute to telomere shortening.

In addition to reducing oxidative stress, physical activity also has a direct effect on telomerase activity. Telomerase is an enzyme that helps maintain telomere length, and studies have shown that physical activity can increase telomerase activity in cells.

One study published in the journal Preventive Medicine found that individuals who engaged in regular moderate to vigorous physical activity had longer telomeres compared to those who were less active. Another study published in the journal Circulation Research found that endurance athletes had longer telomeres compared to sedentary individuals.

It is important to note that the type and intensity of physical activity may also play a role in telomere length. High-intensity interval training (HIIT) has been shown to have a greater effect on telomere length compared to moderate-intensity exercise. Resistance training, such as weight lifting, has also been shown to have a positive effect on telomere length.

Overall, engaging in regular physical activity can be a powerful strategy for promoting telomere length and overall health.
