This study demonstrates that reduced sedentary time (but interestingly not physical exercise) was associated with the lengthening of telomeres in white blood cells in older, overweight sedentary people. This emphasises the importance of reducing sedentary time, as well as increasing everyday physical activity. Clinically, these findings reinforce that the first step for overweight patients is to reduce sedentary time. Concussion and the potential for brain injury are increasingly recognised. Parents may be reluctant to allow their children to participate in concussion-prone sports, such as ice-hockey and American football.
