![]() ![]() ![]() The beauty of wearable devices is that they are worn pretty much 24/7, 360 days of the year, which makes the data collected unprecedented. That’s huge return for small bouts of physical activity, especially if that’s all you can find time to do. As little as three to four minutes a day of high-intensity exercise can reduce the risk of chronic disease by 30 to 40 per cent, even among those who are otherwise sedentary. The ability for wearable devices to capture the intensity of physical activity provides even more insight into how vigorous exercise can affect health. Instead of the recommended minimum of 150 minutes of physical activity per week, data obtained from wearable devices suggest that anywhere from 40 to 60 minutes of moderate to vigorous intensity exercise can reduce the risk of chronic disease. “Current physical activity guidelines largely reflect the dose-response relationship between perceived - rather than actual - levels of physical activity and health outcomes, and the amount of device-measured physical activity needed for health benefits appears to be smaller than previously thought,” said a recent editorial in the British Journal of Sports Medicine. So big is the gap that it has become apparent that the health benefits accrued from current physical activity guidelines can be achieved in less time than previously reported. As more data from devices like Apple, Fitbit, Garmin and Polar smart watches becomes available, researchers are discovering just how big a gap there is between how much people say they exercise and how much they really exercise. Wearable technology offers a more objective view of daily physical activity by working in the background to stealthy track daily movement. ![]()
