We recently showed that 5 days of reduced daily physical activity impair popliteal artery, but not brachial artery, flow-mediated dilation (FMD). However, the mechanisms by which physical inactivity causes leg vascular dysfunction are unclear. We reason that a reduction in leg blood flow-induced shear stress is a primary underlying mechanism by which reduced daily physical activity impairs popl...

Physical activity (PA) has many beneficial physical and mental health effects. Physical inactivity is considered the fourth leading risk factor for global mortality. At present there are no systematic reviews on PA patterns among South Asian adults residing in the region. The present study aims to systematically evaluate studies on PA patterns in South Asian countries. A five-staged comprehensi...

Obesity is associated with physical inactivity, which exacerbates the negative health consequences of obesity. Despite a wide consensus that people with obesity should exercise more, there are few effective methods for increasing physical activity in people with obesity. This lack is reflected in our limited understanding of the cellular and molecular causes of physical inactivity in obesity. W...

See Online/Articles http://dx.doi.org/10.1016/ S0140-6736(12)61031-9 Exercise has been called a miracle drug that can benefi t every part of the body and substantially extend lifespan. Yet it receives little respect from doctors or society. Socially, being inactive is perceived as normal, and in fact doctors order patients to remain on bed rest far more often than they encourage exercise. This ...

This study investigated miR-148b as a potential physiological actor of physical inactivity-induced effects in skeletal muscle. By using animal and human protocols, we demonstrated that the early phase of transition toward inactivity was associated with an increase in muscle miR-148b content, which triggered the downregulation of NRAS and ROCK1 target genes. Using human myotubes, we demonstrated...

movement produced by skeletal muscles that results in energy expenditure above basal level.1,2 Regular physical activity has long been associated with a wide range of physical and mental health benefits.2-10 In addition, exercise training was shown to exhibit numerous positive functional adaptations to the human body.11-13 Physical inactivity, on the other hand, has been considered one of the c...

Sedentary death syndrome (SeDS) is a major public health burden due to its causing multiple chronic diseases and millions of premature deaths each year. Despite the impact of physical inactivity, very little is known about the actual causes of physical inactivity-induced chronic diseases. It is important to study the mechanisms underlying molecular changes related to physical inactivity in orde...

The aims of our study were to investigate the prevalence of risk factors in persons with previously known diabetes ("old DM"), persons with diabetes developed during the 2003-2008 period ("new DM") and diabetes-free individuals within the CroHort study. Risk factors were defined as physical inactivity, unhealthy nutritional regimen, smoking and excessive alcohol consumption, while diabetes stat...
