    All right guys, use this online calculator to estimate your peak oxygen intake ( your VO2(max) ) without having to get out of your chair! As a bonus the calculator reports the 'fitness age' that equates to your estimated VO2(max).

    My fitness age: 24 (!)

    The nerdy details: Norwegian researchers collected physical measurements for 2067 healthy men and 2193 healthy women aged 20 to 90. They established VO2(max) (actually peak oxygen uptake) by running each participant to exhaustion. They then used multiple linear regression to build a statistical model to predict ground truth VO2(max) from the collected measurements. They reserved some of the data as holdout for validation of predictive ability. The final models are segmented by sex; and predict VO2(max) from age, frequency/intensity of physical activity, waist circumference, and resting heart rate. Overall coefficient of determination (R squared) was 61% for males and 56% for females.

    I'm guessing your 'fitness age' is determined by calibrating VO2(max) to age: for all men of a given age, calculate the average observed VO2(max), and report the age whose average VO2(max) equals the value that was predicted for you.

    The methodology seems legit: The experimental protocol is of high quality, the sample seems representative of a wide range of (healthy Norwegian) individuals, the model is not overly complicated for the sample size. The coefficients on the predictors have the right sign. I suppose the researchers could have achieved a better fit by trying out various transformations for the predictors, but perhaps they wanted to keep the model simple.

    It says I am younger than 20! Now that's a calculator I like. icon_biggrin.gif

    Thanks for sharing the link. Very motivating for maintaining an exercise program.

    -20
    Although I wouldn't take this too seriously. When it asked my education level I knew it was going to be based off the statistics of the masses.

    My fitness age is 36... It's funny, this came up at dinner with some friends last night (we all know each other from the gym) and we had a good laugh... But it does make you feel better about yourself!

    First of all, I really do not care about some science study of what my V8, or VO12 should be. I am doubtful of most of these studies. I think non-athletes spend time studying this stuff and not working out. They want to study and not get out and do the work. Guys have been amazingly fit and athletic for years without knowing any of these stats. I am always suspect of any athlete that spends too much time on numbers. That being said, who cares? Lace them up let's race? Strap it on, let's lift.

    What does a person's level of education have to do with VO2 max?

    I got -20 does that mean under 20? I guessed my pulse since it is slower than a second.

    I just did again but answered some questions a little differently and got a fitness age of 27 years old. Still not bad and a little more realistic than <20 when I am 44.

    Odd, my fitness age changes depending on my intensity of work outs. Since I have a sprained ankle, I am limited on what I can do now. Can lift some weights especially on the bench. If I go all out like I do when I can run -20, moderately like now, 27.

    That means your parents are still in kindergarten, and you haven't even been thought of yet. It means you don't exist. icon_eek.gif

    My Fitness Level: YOU HAVE THE FITNESS OF AN AVERAGE under 20 YEAR OLD AND YOUR ACTUAL FITNESS LEVEL IS 58 VO2 MAX - This means that your heart's capacity to transport oxygen is good, which decreases the risk of dying prematurely from cardiac disease icon_cool.gif

    Too many questions, too many levels to navigate. Our doctors tell me I'm younger than my chronological age, and that my husband is medically younger, too - we'll go with that.

    I had a blood flow study done a few months ago, with an echocardiogram and other analysis of my blood vessels. I was told I have the circulation of an average guy who's 30 years younger than me. No blood vessel narrowing, no plaque build up, no nuttin'.

    My heart efficiency's as good as any can be, too, no enlargement, perfect. And the blood flow in my carotid arteries, tested individually, is supplying my brain as well as a youngster could expect, with no sign of potential narrowing or clotting.

    I've now stopped carrying the nitro tablets the VA doctors said I needed back about 13 years ago, when they thought I had some heart oxygen deficiency. All subsequent studies by (competent) cardiologists outside the VA have failed to find the same results.

    I was asked if I'd been an athlete during my life. Well, not professionally, I said. Just Army service for 25 years, taught college phy ed gym classes for years, avid tennis player in my youth, long distance bicyclist since age 13, swimmer, outdoorsman, still golf, only slowed down in recent years by my physical mobility limitations due to bone joint problems.

    Well, that history shows in these tests, I was told. "You're gonna live to be over 100." A good reason to stay in shape, Real Jocks!

    My husband's been told the same thing. To which, sitting beside him, I asked: "Doctor, you're saying he's gonna live to be 120? Can I have a second opinion?" Of course I got smacked, right in front of the laughing doctor. icon_redface.gif

    My VO2 max is 54 and my fitness age is 25. This appears to be pretty accurate because in races my time is always in the top 50%, of men in this age group,even though I am 57. In my own 55-59 age group I am competing for awards for 1st-3rd place and receive awards in about 50% of the races I do. I think family genes play an important role in longevity, besides fitness level. All my great grandparents, grand parents, and now my own parents are living very healthy lives in their 90's, so family history is definitely on my side.
