In "Effect of Prolonged Sitting and Breaks in Sitting Time on Endothelial Function," forthcoming in Medicine & Science in Sports & Exercise, researchers from IU Bloomington report on a study that holds out hope for anyone worried about the health effects of prolonged sitting.
If you've heard that Sitting is Killing You, you probably have some low-grade continuous anxiety about the fact that you still end up sitting at a computer for most of the day, most days. But a five minute/hour slow walking break was shown to guard against the worst circulatory effects of sitting.
The study involved 11 non-obese, healthy men between the ages of 20 and 35 who participated in two randomized trials. In one trial they sat for three hours without moving their legs. Researchers used a blood pressure cuff and ultrasound technology to measure the functionality of the femoral artery at baseline and again at the one-, two- and three-hour mark.
In the second trial, the men sat during a three-hour period but also walked on a treadmill for five minutes at a speed of 2 mph at the 30-minute mark, 1.5-hour mark and 2.5-hour mark. Researchers measured the functionality of the femoral artery at the same intervals as in the other trial.
Short walking breaks found to reverse negative effects of prolonged sitting

The deadly 2013 El Reno tornado was 2.5 miles (4 km) wide and killed a team of tornado experts. But as Anton Seimon explains, his colleagues turned that tragedy into an opportunity to confirm a key element of tornado formation.
Some snakes have evolved the ability to glide through the air. For example, paradise tree snakes in southeastern Asia can launch off from a branch and fly as far as 10 meters. Scientists have known that the snakes flatten their bodies to gain lift but new research reveals that they also undulate their bodies as […]
We humans are castaways on an ocean of uncertainty. Since the beginnings of history, our ancestors sought knowledge and understanding about their lives, their relationship with the cosmos, and perhaps take a peek into their future. In such effort—long before the answers of science—earthlings developed a rich variety of divination practices and systems. Many forms […]
When revved-up kids used to dribble a basketball through the kitchen or practice their footwork with a soccer ball in front of the television, exasperated parents would often just send ‘em outside to play. But these days, sending kids out might not be the best course of action. Despite all the changes, many budding young […]
When you sit down to play a new AAA video game like The Last of Us 2, you probably assume it was created by gaming experts with insane levels of artistic and technical talent. And…you’d be right. Top developers are craftsmen of the highest order, pouring literally thousands of man-hours into creating the greatest gaming […]
Earlier this year, we learned that Python had finally accomplished a feat other programming languages had failed for decades, to surpass Java as the second most-used coding language in the world. For its versatility and ease of use alone, its ascent among programmers isn’t hugely surprising. Then when you factor in its key role in […]
