For those of us who sit in front of our computers much of the day--
One Australian study showed that for every additional hour a woman sits in front of the TV, her risk of metabolic syndrome - a precursor to diabetes and cardiovascular disease - increases by 26%, irrespective of how much moderate exercise she does.
And the health of people who already do too little exercise will suffer even more if combined with prolonged bouts of sitting, say the authors.
More research is needed to establish a causal effect between prolonged sitting and ill health, say the authors, but some underlying mechanisms have already been identified, including an enzyme (lipoprotein lipase) that has a key role in the regulation of key blood fats.
Accordingly, the authors propose a new model or paradigm of “inactivity physiology” which recognises that sitting and non-muscular activity may independently boost the risk of ill health, and that sedentary behaviour is a distinct class of behaviour with specific consequences for ill health, which are not the same as those sparked by taking too little exercise.
The molecular and physiological responses of the body prompted by too much sitting cannot simply be cancelled out by taking additional exercise, say the authors.
“In the future, the focus in clinical practice and guidelines should not only be to promote and prescribe exercise, but also to encourage people to maintain their intermittent levels of daily activities [that involve movement],” they add. “Climbing the stairs, rather than using elevators and escalators, five minutes of break during sedentary work, or walking to the store rather than taking the car will be as important as exercise.”
