Can sitting too much kill you?
Even if you are meeting current physical activity guidelines by exercising for one hour per day, that leaves 15 to 16 hours per day when you are not being active. Does it matter how you spend those hours?
By Travis Saunders
''individuals who sat the most were roughly 50% more likely to die during the follow-up period than individuals who sat the least, even after controlling for age, smoking, and physical activity levels.
The greater the number of breaks taken from sedentary behavior, the lower the waist circumference, body mass index, as well as blood lipids and glucose tolerance.
sedentary behavior also results in rapid and dramatic changes in skeletal muscle.
these physiological changes in skeletal muscle have little or nothing to do with the accumulation of body fat, and occur under extremely rapid time-frames.
We sit at work, we sit at school, we sit at home, and we sit in our cars as we commute back and forth''
