TLDR
Physical function significantly declined over 3 years, in particular in the oldest group, and a subtle decline in psychological health paralleled decline in physical function but did not accelerate it.Abstract:
Background. Decline of physical function with age is associated with substantial health consequences. Physical and psychological functioning is linked, but the temporal nature of this association remains unclear. Methods. Three-year follow-up data from men and women (n = 1,741), aged 68–82 years, in the longitudinal study on nutrition and successful aging (NuAge; Quebec, Canada) were used. Growth curve modeling was performed to examine trajectories of a global physical performance score across time as conditioned by cognition and depression. Results. Significant decline in physical function was observed ( p 77 years; age 2 : p < .01) but not affected by slight decline in cognition or depression. Yet, people with lower cognition level and more depressive symptoms show lower physical capacity throughout the entire follow-up period (p < .0001). Conclusions. Physical function significantly declined over 3 years, in particular in the oldest group. A subtle decline in psychological health paralleled decline in physical function but did not accelerate it.read more

TL;DR: This data indicates that physical activity levels decline and health worsens as the authors age, however, estimates of the impact of physical inactivity for population health often fail to specifically focus on older adults.

TL;DR: A systematic review of English-language research published between 2000 and 2011 to evaluate the relations between rates of change in physical and cognitive functioning in older cohorts found that change in grip strength was more strongly correlated with mental state, while change in walking speed was more heavily correlated with change in fluid cognition.

TL;DR: In addition to the previously observed association with lean mass, an even distribution of daily protein intake across meals is independently associated with greater muscle strength, but not with the mobility score, in older adults.

The Timed “Up & Go”: A Test of Basic Functional Mobility for Frail Elderly Persons
TL;DR: This study evaluated a modified, timed version of the “Get‐Up and Go” Test (Mathias et al, 1986) in 60 patients referred to a Geriatric Day Hospital and suggested that the timed “Up & Go’ test is a reliable and valid test for quantifying functional mobility that may also be useful in following clinical change over time.
