Adherence
Higher daily physical activity in nonagenarians (90+ years) is positively associated with better physical functionality, specifically the ability to walk further in a timed test.
For those in their 90s, staying active is directly linked to maintaining the ability to move independently. Even small increases in daily activity (Physical Activity Level) correlate with walking further and having better physical functionality. Prioritize daily movement to preserve mobility.
GoodSupportsHIGH confidence
Interestingly, PA was similar between young volunteers and those who were in their 60s and 70s... nonagenarians who were more active on a daily basis walked further during a timed test, indicating higher physical functionality.
Why this rating
Objective measurement of activity and functionality in a specific, hard-to-reach demographic.
