Exercise only slightly lessens the health risks of prolonged sitting, scientists with the National Cancer Institute have concluded, after eight years following almost 250,000 American adults.
When we’re stationary, blood
sugar spikes and insulin levels get out of whack.
Interestingly,
jogging doesn’t improve blood sugar regulation any more than standing
and walking does. Scientists say what’s important is to break up long
hours of sitting.
Experiments
at the University of Massachusetts show that when volunteers stood all
day — nothing else; no walking or jogging; just standing — they burned
hundreds more calories than when they sat for the same period of time.
