Comment on "physical activity volume, intensity and life expectancy"

• Higher combinations of volume and intensity of physical activity are associated with increased longevity in older adults enrolled in the UK Biobank study. • Compared to more active older adults, the least active gain the most longevity by adding a 10-min and a 30-min brisk walk to their usual daily physical activity habits. • Researchers and practitioners may need to familiarize themselves with new accelerometer scoring metrics, which use average acceleration units and intensity gradients. • Analyzing research on physical activity and life expectancy by gender is crucial due to differences between men and women in their physiological responses and mortality rates.
