Current physical activity recommendations have been based on evidence from systematic
reviews of questionnaire-based data. Questionnaire-based physical activity data are subject …

Background The dose–response relation between physical activity and all-cause mortality is
not well defined at present. We conducted a systematic review and meta-analysis to …

In a meta-analysis we investigated the effect of physical activity with different intensity
categories on all-cause mortality. Many studies have reported positive effects of regular …

Introduction One major limitation of prior studies examining the influence of physical activity
on mortality is use of self-reported measures. This study examined the association between …

Background Although previous studies have found physical activity to be associated with
lower mortality, the dose–response relationship remains unclear. In this systematic review …

Purpose Physical activity guidelines recommend at least 150 min of moderate-intensity
physical activity (MPA), 75 min of vigorous-intensity physical activity (VPA), or combination of …

Objectives. We examined the association of intensity and type of physical activity with
mortality. Methods. We assessed the duration of physical activity by intensity level and type …

Background Physical inactivity is a major public health problem associated with increased
mortality risk. It is, however, poorly understood whether vigorous physical activity is more …

OBJECTIVE.: Little is known regarding health-related quality of life and its relation with
physical activity level in the general population. Our primary objective was to systematically …

Background Sedentary behavior is related to increased mortality risk. Whether such
elevated risk can be offset by enhanced physical activity has not been examined using …
