Fortunately for those of us who are often attached to their pupils, exercise specialists agree that any movement, however slight, is considered physical activity and may be consecutive [19659002]. In a 2017 study, researchers found that while office workers used a specialized sub-office, a bike-like device – which allowed them to sit while pedaling lightly – they burned 20% more calories during of a day's work than if they were just sitting down.
The dynamic position also seems to reduce one of the most disturbing effects of sedentary lifestyle: When we sit, without moving, the arteries in our legs slow down, affecting the function of these vessels and potentially contributing with time arterial stiffening and increased blood pressure.
A 2016 experience shows that stirring, even a little, can help. In the study, a group of healthy young volunteers were asked to sit, keeping one foot flat against the ground, for three hours. During this time, they moved and tapped their foot every two minutes
At the end of the three hours, blood flow, measured by ultrasound, was found to be lower in the still leg than at the beginning of the study. . But the flow had increased in the other leg.
"We were surprised by the magnitude of the difference" between the two legs, said Jaume Padilla, a professor at the University of Missouri and author of the study. The message of his and other research is that if you are stuck in a seat for an extended period, aim to make your session dynamic. Press your toes, stir or otherwise, move.
