A paper by McRoberts’ founder and CEO Rob van Lummel on physical function in old age appeared in PLoS ONE this month. This paper demonstrates that physical performance (what you can do) and physical activity (what you actually do) are associated but different domains of physical function: older adults who do very well on physical performance tests are not per se more active. Physical performance scores and physical activity in daily life correlated only moderately. This study suggests that an improvement of physical performance does not automatically imply a change to a more active lifestyle. The full article can be read here.
