Q: Does "moving on the spot" in a seated position (for example, bending or stretching one's feet) count as an activity to counter sedentariness, or should one actually get up or move, as it's currently recommended?
A: Fortunately for those of us who are often attached to the office, exercise scientists agree that any movement, no matter how light, is considered physical activity and may be significant .
On the one hand, moving and shaking in our chairs, which some researchers call oxymoronically dynamic sitting, burns calories. 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 about 20% more calories during a work day. The dynamic session also seems to reduce one of the most disturbing effects of a sedentary lifestyle on health: when we sit for hours, the blood flow in the main arteries of our legs slows down, affecting the function of these vessels and may contribute over time to arterial stiffening and increased blood pressure.
