Timing of physical activity in relation to liver fat content and insulin resistance

Aims/hypothesisWe hypothesised that the insulin-sensitising effect of physical activity depends on the timing of the activity. Here, we examined cross-sectional associations of breaks in sedentary time and timing of physical activity with liver fat content and insulin resistance in a Dutch cohort.MethodsIn 775 participants of the Netherlands Epidemiology of Obesity (NEO) study, we assessed sedentary …

Causal analysis identifies small HDL particles and physical activity as key determinants of longevity of older adults

BackgroundThe hard endpoint of death is one of the most significant outcomes in both clinical practice and research settings. Our goal was to discover direct causes of longevity from medically accessible data.MethodsUsing a framework that combines local causal discovery algorithms with discovery of maximally predictive and compact feature sets (the β€œMarkov boundaries” of the response) …

Association of Leisure Time Physical Activity Types and Risks of All-Cause, Cardiovascular, and Cancer Mortality Among Older Adults

Higher amounts of physical activity are associated with increased longevity. However, whether different leisure time physical activity types are differentially associated with mortality risk is not established.Objectives To examine whether participation in equivalent amounts of physical activity (7.5 to <15 metabolic equivalent of task [MET] hours per week) through different activity types is associated with …

Association of Accelerometer-Measured Sedentary Time and Physical Activity With Risk of Stroke Among US Adults

Importance The amount and intensity of physical activity required to prevent stroke are yet to be fully determined because of previous reliance on self-reporting measures. Furthermore, the association between objectively measured time spent being sedentary as an independent risk factor for stroke is unknown. Objective To investigate the associations of accelerometer-measured sedentary time and physical …

Role of Cardiovascular Risk Factors on the Association Between Physical Activity and Brain Integrity Markers in Older Adults

Objective: Physical activity has been associated with a decreased risk for dementia, but the mechanisms underlying this association remain to be determined. Our objective was to assess whether cardiovascular risk factors mediate the association between physical activity and brain integrity markers in older adults. Methods: Participants from the Age-Well study underwent, at baseline, a physical …
