Another way of knowing how long an individual would live is determined through a standard treadmill stress test . It has been used by researchers on more than 58,000 subjects , with ages 18 to 96 . After basing it on age and sex, the two predictors that will tell if the patient will still be alive in 10 years are how highly energized their metabolism was and how fast their heart would beat during the test.
The metabolism of an individual is tallied by using “ metabolic equivalent of tasks” or what they call METs, it is the measure of how much energy an individual may spend during a task. The higher the MET level is achieved , the more chances that the subject would live for another decade.
The easier an individual would reach his maximum heart rate while running , the more likely that he would die within 10 years, in contrast to an individual who only reached 85 percent of maximum heart rate during the test. The maximum heart rate was learned by subtracting the individual’s age from 220 . This formula has been used for decades by both exercisers and doctors .
“In medicine we usually base predictions of survival on the absence or presence of a disease state,What’s new here is that there is now a fancy equation doctors can use to compare the chances of survival for one 50-year-old woman against another 50-year-old woman.” Dr. Jennifer Ashton , ABC News medical contributor , explained the entire procedure of the test on Good Morning America.
“Rather than being viewed as morbid, experts should be able to use this information to motivate people to change their behavior”, Ashton said.” Everyone can improve their survival score by more often and pushing it a little harder when they do,” she added.
“This is in your power to change and improve your numbers. You can actually change your own destiny,” she said.
