Data from a wearable activity tracker can be used to obtain metrics related to the user’s physical health

A new Johns Hopkins study shows that data collected from activity tracking devices can be used to derive several metrics related to the wearer’s general physical health and cardiovascular health. While these sensors are typically marketed as daily step counters, the Johns Hopkins research team believes they could potentially serve a larger purpose: aiding clinical …

Exercise can beneficially alter subcutaneous adipose tissue, which can improve metabolic health

Exercise is one of the first strategies used to treat obesity-related health problems like type 2 diabetes and other cardiovascular diseases, but scientists don’t understand exactly how it works to improve metabolic health. To that end, researchers at the University of Michigan studied the effects of three months of exercise on obese people and found …
