Physical inactivity causes endothelial dysfunction in healthy young mice.
OBJECTIVES We sought to determine if physical inactivity affects endothelial function in young healthy individuals. BACKGROUND Recent studies have linked exercise training to increased bioavailability of vascular nitric oxide (NO) and to improved endothelial function in patients with cardiovascular disorders. The effects of physical inactivity on normal vascular endothelial function are not k...
متن کاملEnforced physical inactivity increases endothelial microparticle levels in healthy volunteers.
A sedentary lifestyle has adverse effects on the cardiovascular system, including impaired endothelial functions. Subjecting healthy men to 7 days of dry immersion (DI) presented a unique opportunity to analyze the specific effects of enhanced inactivity on the endothelium. We investigated endothelial properties before, during, and after 7 days of DI involving eight subjects. Microcirculatory f...
متن کاملPhysical inactivity increases oxidative stress, endothelial dysfunction, and atherosclerosis.
OBJECTIVE Sedentary lifestyle is associated with increased cardiovascular events. The underlying molecular mechanisms are incompletely understood. Reactive oxygen species (ROS) contribute to endothelial dysfunction and atherosclerosis. An important source of vascular ROS is the NADPH oxidase. METHODS AND RESULTS C57BL6 mice were subjected to regular housing (physical inactivity) or voluntary ...
متن کاملExperimental Sleep Restriction Causes Endothelial Dysfunction in Healthy Humans
BACKGROUND Epidemiologic evidence suggests a link between short sleep duration and cardiovascular risk, although the nature of any relationship and mechanisms remain unclear. Short sleep duration has also been linked to an increase in cardiovascular events. Endothelial dysfunction has itself been implicated as a mediator of heightened cardiovascular risk. We sought to determine the effect of 8 ...
متن کاملPhysical inactivity rapidly induces insulin resistance and microvascular dysfunction in healthy volunteers.
OBJECTIVE Sedentary lifestyle increases the risk of cardiovascular disease and diabetes. Vascular dysfunction contributes to atherogenesis and has been linked to insulin resistance. METHODS AND RESULTS We measured insulin sensitivity by glucose tolerance test and vascular function by ultrasound and venous occlusion plethysmography in 20 healthy subjects (14 men, 6 women) at baseline and durin...
