Two Hours Of Sitting Negates 20 Minutes of Exercise

How bad for you, exactly, is sitting on your butt? Researchers at the UT Southwestern Medical Center have done the math, and the answer is discouraging: two hours of sedentary behavior can be just as harmful as 20 minutes of exercise is beneficial. A UT Southwestern Medical Center news releaseimages reports that researchers analyzed accelerometer data from more than 2,000 men and women between the ages of 12 and 49 with no known history of heart disease, asthma, or stroke, and measured their average daily physical activity and sedentary behavior times. Fitness was estimated using a treadmill test, and variables were adjusted for gender, age, and body mass index. The envelope please…. the researchers found that the negative effect of six hours of sedentary time on fitness levels was similar in magnitude to the benefit of one hour of exercise. What exactly is “sedentary time”? More bad news: “Sedentary behavior involves low levels of energy expenditure activities such as sitting, driving, watching television, and reading, among others.”

    More studies would be needed.
