Your ‘fitness age’ predicts how long you’ll live better than your actual age

This may shock you, but: the fitter you are, the longer you're likely to live. A team of US researchers has devised a method that translates physical fitness into a physiological age, which their analysis reveals is a better predictor of long-term survival than your actual chronological age.  Their method, documented in the European Journal of Preventive Cardiology, was devised by cardiologists at the Cleveland Clinic. Over a decade-and-a-half period, more than 125,000 patients underwent an exercise stress test to help diagnose heart problems, which involved walking on a treadmill at progressively faster speeds. The patients' exercise capacity, their chronotropic competence (how their hearts responded to exercise), and their heart rate recovery after the test were all punched into an equation that calculated a metric dubbed A-BEST, short for “age based on exercise stress testing”. The average chronological age of the (mostly male) patients was 53.5, but their average physiological age — their A-BEST — was a little younger. Patients were followed up for an average period of almost nine years, during which almost 10 percent of them died. Read more here >>>
