Today鈥檚 smartphones allow for increased opportunities for activities traditionally defined as sedentary behaviors, such as surfing the internet, emailing and playing video games. However, researchers Jacob Barkley and Andrew Lepp, faculty members in the College of Education, Health and Human Services at 两性色午夜 University, linked high cell phone use to poor fitness in college students.
Barkley and Lepp were interested in the relationship between smartphones and fitness levels because, unlike the television, phones are small and portable, therefore making it possible to use them while doing physical activity. But what the researchers found was that despite the phone鈥檚 mobility, high use contributed to a sedentary lifestyle for some subjects.
More than 300 college students from the Midwest were surveyed on their cell phone usage and activity level. Of those students, 49 had their fitness level and body composition tested. The researchers鈥 results showed that high cell phone use was associated with low cardiorespiratory fitness. In the study, the students who were the least fit were those who spent large amounts of time on their cell phones 鈥 as much as 14 hours per day. The most fit students were those who used the cell phone the least 鈥 around 90 minutes per day.
One subject said in the interview data: 鈥淣ow that I have switched to the iPhone I would say it definitely decreases my physical activity because before I just had a Blackberry, so I didn鈥檛 have much stuff on it. But now, if I鈥檓 bored, I can just download whatever I want.鈥
The study is believed to the first to assess the relationship between cell phone use and fitness level among any population. Barkley and Lepp conclude that their findings suggest that cell phone use may be able to gauge a person鈥檚 risk for a multitude of health issues related to an inactive lifestyle.
The study appears online in the International Journal of Behavioral Nutrition and Physical Activity.
