So it seems my former co-workers who worked out during their lunch hour instead of dining out like I did might’ve been on to something. According to research conducted by Dr. Jarett Berry and his team at UT Southwestern Medical Center, an hour of physical exercise can counteract the effects of sitting for six to seven hours per day.
The results were based off of a survey of 2,223 participants between the ages of 12 and 49 who wore accelerometers for a week to measure activity levels and sedentary behavior. Researchers found that sitting was linked to lower heart fitness. They also found that those who sat less had better fitness.
Berry concludes that any movement – walking, taking the stairs, or even fidgeting in your seat – is likely better than sitting still.
