Exercise intensity not linked to mortality risk in older adults, finds trial — ScienceDaily
Exercise intensity appears to make no difference to risk of mortality among older adults, suggests a randomised controlled trial from Norway published by The BMJ today.
Physical activity has been highlighted as one of the most important actions people of all ages can engage in to improve health, and data from observational studies show that early death is significantly reduced in physically active compared with inactive individuals.
Yet high quality clinical trial evidence on a potential direct (causal) relation between current advice on physical activity levels and longevity is lacking.
So an international research team set out to evaluate the effect of five years of supervised exercise training compared with recommendations for physical activity on mortality in older adults (70-77 years).
The trial involved 1,567 participants (790 women and 777 men) living in Trondheim, Norway, with an average age of 73 years. In total, 87.5% of participants reported overall good
