Some say that 30 is the new 20 and 50 is the new 40. But what about 45 as the new 20? Or 20 as the new 55? The Norwegian University of Science and Technology says this may be the case depending on your fitness age. You may have lived for 30 years on Earth, but your body may show the wear and tear of someone 20 years older.
Your fitness age is a calculation that determines how effectively your body uses oxygen. It reflects the internal state of your body. It has been described as an indicator of your overall health. Calculations are based on your age, waistline, activity level and your resting heartbeat.
To find out your fitness age, go to Fitness Age Calculator
A Gallup survey, states about 70% of people in the US are either overweight or obese; so most Americans who try out the calculator would probably get a fitness age that’s higher than their actual age.
A 45-year-old man weighing 180 lbs. with a 34-inch waistline and a resting heart rate of 72, actually has the fitness age of a 48-year-old if he only exercises once or twice a week at low- to moderate-intensity.
Conversely, an agile 160-pound 60-year-old who exercises at the same intensity and frequency and has the same heart rate, yet has a 31-inch waist, sports the fitness age of a 52-year-old.
Researchers’ say despite the two men being 15 years apart in chronological age, the 60-year-old likely has many more years ahead of him if both stay on course. The good news is that fitness age, unlike chronological age, is reversible. The 45-year-old man, if he starts exercising more and cuts a few inches from his waist, stands to extend his life span considerably.
