MVPA, Sedentary Time and Physical Function

PURPOSE: Sedentariness has been proposed as an independent risk factor for poor health. However, few studies have considered associations of sedentary time (ST) with physical functional health independent of time spent in moderate-to-vigorous physical activity (MVPA). METHODS: Community-based men and women (n = 8623, 48-92 yr old) in the European Prospective Investigation of Cancer-Norfolk study attended a health examination for objective measurement of physical capability, including grip strength (Smedley dynamometer (kg)), usual walking speed (UWS (cm·s(-1))), and timed chair stand speed (TCSS (stands per minute)). Of these, 4051 participants wore an accelerometer (GT1M ActiGraph) for 7 d to estimate time spent in MVPA (MVPA, ≥1952 counts per minute) and ST (ST, 0.05). CONCLUSIONS: More time spent in MVPA was associated with higher physical capability, but there were no independent ST associations.VLK declares a Wellcome Trust clinical training fellowship [092077/Z/10/Z] and KW a British Heart Foundation basic science research fellowship [FS/12/58/29709].
