How well you respond to exercise, may actually be a better indication of life expectancy than your chronological age.
New research in the US conducted by researchers at the Cleveland Clinic study looked at 126,356 patients, all of who were an average age of 53.5 years. All of them came to the clinic for a test that also diagnosis heart problems – their first exercise stress test.
The study, published in the European Journal of Preventive Cardiology took place over a period of 8.7 years. The study showed the formula developed by the researchers calculated how well people respond to exercise using A-BEST (Age Based on Exercise Stress Testing) i.e the formula calculated the “physiological age” of the person.
For the test, patients had to walk on a treadmill which gradually got more difficult such that their heart rate response to the exercise and the recovery rate could be measured by their exercise capacity.
The findings after taking into account gender, smoking, body mass index, statin use, diabetes, hypertension, coronary artery disease, end-stage kidney disease and any medications that affect heart rate showed that the A-BEST was a significantly better predictor of mortality than chronological age
The study author Dr Serge said the study proved that if you want to live longer then you need to exercise more because it improves your length of life by improving health.
A-BEST could also be used by doctors when giving patients the results of exercise testing. Telling patients their estimated age based on exercise performance is a powerful estimate of longevity and easier to understand than providing results for the individual components of the examination.
Usually age predicts mortality death best, but this study proved otherwise. Dr Serge said, “Telling a 45-year-old that their physiological age is 55 should be a wake-up call that they are losing years of life by being unfit. On the other hand, a 65-year-old with an A-BEST of 50 is likely to live longer than their peers.”
