Objective The later-age shift towards physical inactivity and sedentary behaviour is
associated with comorbidity and reduced function: markers of frailty. Whether these …

Background The combined association of physical activity and sedentary behavior with
adverse health factors is not yet clear in the literature. A combined analysis of physical …

Background Frail older adults are heavy users of health and social care. In order to reduce
the costs associated with frailty in older age groups, safe and cost-effective strategies are …

OBJECTIVES To examine the longitudinal association between frequency of moderate
physical activity (PA) and overall, physical, psychological, and social frailty among …

Objective Lifestyle factors such as physical activity are known to reduce the risk of frailty.
However, less is known about the frailty-sedentary behavior relationship. A systematic …

Heterogeneity in aging can be explained by frailty. Lifestyle behaviors such as physical
activity can help manage frailty levels. Conversely, sedentary behaviours are associated …

Background It is unclear if physical activity (PA) can prevent or reverse frailty. We examined
different doses and types of PA and their association with the onset and severity of frailty …

Background Self-reported low physical activity is a defining feature of phenotypic frailty but
does not adequately capture physical activity performed throughout the day. This study …

Background. There are scarce studies of the long-term associations between leisure-time
physical activity (LTPA) in midlife and phenotypic frailty in old age. Methods. We studied …

Background: Self-reported measures of decreased aerobic fitness and low physical activity
are criteria of frailty. However, research assessing aerobic fitness and physical activity levels …
