Blast from the Past
You might want to stand up for this one: yet another study suggests that a single bout of exercise alone is not enough to mitigate the harmful effects of too much sitting.
This particular study used healthy, normal weight adults and put them through one of three experimental conditions: continuous sitting for 9 hours, brisk walking for 30 minutes and then sitting for the remainder of the 9 hours, and regular activity breaks that provided a total of 30 minutes over the 9 hour period. The authors found that not only did regular activity significantly reduce blood sugar and insulin compared to sitting all day, but that it had similar benefits compared to the 30 minutes of physical activity combined with prolonged sitting.
Like the studies that have come before, this study suggests that regularly breaking up periods of prolonged sitting may be a very important thing to do for your health. I’ve written about the dangers of excessive sitting before, and this research further demonstrates that even in healthy people, blood sugar control is impaired by prolonged sitting, even if these people had previously exercised before the bout of sitting.
This study reinforces my recommendation to stand up for at least two minutes every hour, taking a brief walk or doing some light stretching. As this study confirms, even short breaks like this throughout the day can make a big difference.
