Adherence
Higher cumulative physical exercise duration (minutes per month) is inversely associated with serum levels of biomarkers for DNA damage and telomere dysfunction, independent of chronological age.
Regular physical exercise helps reduce biological markers of DNA damage and telomere dysfunction in your blood. The more you exercise (measured in minutes per month), the lower these markers tend to be, independent of your age. Incorporating regular exercise is a key strategy for maintaining cellular health.
In contrast, exercise was associated with an age-independent reduction in the expression of biomarkers of DNA damage in human blood.
Why this rating
Observational cohort study with statistical correction for age. The association is significant (P=0.0127) but the correlation is moderate.
