Sitting appears to increase chances of heart disease, even in people who exercise. We’ve written about this before.
New info, reported on in the NY Times:
Regular workout sessions do not appear to fully undo the effects of prolonged sitting. ‘‘There seem to be different pathways’’ involved in the beneficial physiological effects of exercising and the deleterious impacts of sitting, says Tatiana Warren, a graduate student in exercise science at the University of South Carolina and the lead author of the study of men who sat too much. ‘‘One does not undo the other,’’ she says.
In a number of recent animal studies, when rats or mice were not allowed to amble normally around in their cages, they rapidly developed unhealthy cellular changes in their muscles. The animals showed signs of insulin resistance and had higher levels of fatty acids in their blood. Scientists believe the changes are caused by a lack of muscular contractions.
