SMSing might be turning you into a couch potato

Think your cellphone cuts down on admin and makes life easier? That might be true for organising your calender, but this study suggests that it is might be making you less fit and less healthy. The study investigated the link between cellphone use, sedentary behaviours, and cardio-respiratory fitness among varsity students. In the first phase 305 students were asked to indicate the total amount of time per day they spend using their mobile phone, the number of text message they got and sent, and the number of calls they got and made each day. On average, the students spent about 5 hours a day using their cell phones. The students were asked if they wished to continue taking part in the study and a group of 49 randomly chosen volunteers took part in phase two of the study. They were asked about their leisure time activities and underwent a treadmill test to measure their cardiorespiratory fitness. Higher total cell phone use, as well as more texting and calling, was associated with lower fitness levels. There were other differences between low intensity cell phone users (average of 101 minutes per day) and high intensity users (average 840 minutes per day). Compared to low intensity users, high intensity users reported more sedentary leisure time activities, such a surfing the net or playing video games. When they were active, high intensity users noted that cellphone use interfered with their physical pursuits, such call from friends interrupting workouts. Low frequency users reported more physically active pursuits and said their cell phones helped keep them in touch with other active friends and increased their activity levels. When active, low intensity users tended to turn off their phones so they would not be interrupted.
