Screen Time and Physical Activity

Posted by Sarah on June 15, 2013 at 11:15 PM

Increased screen time has been suggested as a potential explanation for decreased exercise behavior. The displacement hypothesis proposes a zero sum relationship between screen time and physical activity. Researcher’s utilized this to survey 461 males and 275 females in a college setting. In comparison to females, males had higher BMI, more days of aerobic exercise, strength training, screen time and television watching, while females reported more time spent on homework. Homework was considered a sedentary behavior but was not included in the screen time category. Therefore, males had more recreational time. The researchers concluded that more females were classified as insufficiently active and may have had little time for physical activity. It is this demographic that may benefit most from a short high intensity interval training session due to inherently shorter duration of activity.
