What’s your fitness age?

Please follow and like us:

The researchers evaluated almost 5,000 Norwegians between the ages of 20 and 90, using mobile labs. They took about a dozen measurements, including height, body mass index, resting heart rate, HDL and total cholesterol levels. Each person also filled out a lengthy lifestyle questionnaire. Finally, each volunteer ran to the point of exhaustion on a treadmill to pinpoint his or her peak oxygen intake (VO2 max), or how well the body delivers oxygen to its cells. VO2 max has been shown in large-scale studies to closely correlate with significantly augmented life spans, even among the elderly or overweight. In other words, VO2 max can indicate fitness age.

In order to figure out how to estimate VO2 max without a treadmill, the scientists combed through the results to determine which of the data points were most useful. You might expect that the most taxing physical tests would yield the most reliable results. Instead, the researchers found that putting just five measurements — waist circumference; resting heart rate; frequency and intensity of exercise; age; and sex — into an algorithm allowed them to predict a person’s VO2 max with noteworthy accuracy, according to their study, published in the journal Medicine & Science in Sports & Exercise.

The researchers used the data set to tabulate the typical, desirable VO2 max for a healthy person at every age from 20 to 90, creating specific parameters for fitness age. The concept is simple enough, explains Ulrik Wisloff, the director of the K. G. Jebsen Center of Exercise in Medicine at the Norwegian University and the senior author of the study. “A 70-year-old man or woman who has the peak oxygen uptake of a 20-year-old has a fitness age of 20,” he says. He has seen just this combination during his research.

The researchers have used all of this data to create an online calculator that allows people to determine their VO2 max without going to a lab. You’ll need your waist measurement and your resting heart rate. To determine it, sit quietly for 10 minutes and check your pulse; count for 30 seconds, double the number and you have your resting heart rate. Plug these numbers, along with your age, sex and frequency and intensity of exercise, into the calculator, and you’ll learn your fitness age.

The results can be sobering. A 50-year-old man, for instance, who exercises moderately a few times a week, sports a 36-inch waist and a resting heart rate of 75 — not atypical values for healthy middle-aged men — will have a fitness age of 59. Thankfully, unwanted fitness years, unlike the chronological kind, can be erased, Dr. Wisloff says. Exercise more frequently or more intensely. Then replug your numbers and exult as your “age” declines. A youthful fitness age, Dr. Wisloff says, “is the single best predictor of current and future health.”

🌻 I haven’t went on a rant in awhile so if you don’t care to hear it... here’s your chance to exit 😝
MY QUESTION IS: Why do so many of us struggle to find happiness?! - HAPPINESS is at the top of everyone’s list. At the end of the day, we want to feel like we’re happy and have lived well. But oftentimes, we can find ourselves feeling unhappy and we may feel like we’re not sure why happiness isn’t happening for us.
- - - - - -
Most of the time when you have a negative thought or feel unhappy, you’ll read tons of self-help books that tell you to replace that negative thought with a positive one, they may also tell you to spend no more than 60 seconds thinking about it and move on about your day. (Easier said than done) That’s great advice and all but to me, all that does is sweep your negative thinking under the rug and the rug along with that negative thought is still there. Every person who has ever been on a weight loss diet understands this: “just don’t think about food” they say, (again, easier said than done) - this simply just does not work especially for the long haul.

My thoughts: 💭 The next time you’re having a bad day or a negative thought about something, don’t ignore your emotions or thinking and “put on a happy face.” Instead, try accepting the way you feel and try to identify why you are feeling the way you are. By ending the internal struggle of how you actually feel, you can begin to understand your “WHY”— And by understanding yourself and your thoughts a bit better, you come to life’s choices with the most powerful tool of all: YOUR FULL SELF! To me: I feel as though, this is a much better way to choose happiness for yourself. In the end; YES!! happiness is a choice but to understand yourself better will allow your own sense of happiness to shine in brighter than anything else! ☀️🌈🌸
