What is the maximum Cardio Fitness Score?-Ionic

[SunsetRunner]

So I am fairly in shape. I am a gym addict but an Irish Dancer all my life so I have always had great cardio fitness. After a few runs my Cardio Fitness registered at 54. Then it went to 55. Then the dot kept moving up the scale but my fitness score stayed the same.

Is 55 the max?

On the cardio fitness screen it displays 55 as last number.

On the first page displaying for example here:

Excellent: >55

Very Good: 49.6 - 55

..

Poor: <33.5

For Excellent it's any number above 55, though Fitbit seems to display 55 as last (cardio fitness) number, but the fitness level can increase beyond to the number 55 up to 81 (or more?).. as Ryan Hall according to Fitbit is at 81, and the bar goes a little bit further than that..

Thanks for the reply, but if you look at the image I attached, it shows the
number 55, but my dot continues to move past 55? Anyone from Fitbit able to
say whether they stop at 55 or not?

I've got 57 so it looks like you can achieve > 55.

Thanks! Mine just moved to 56! Sweet! I have a challenge to keep me going!

I think the number is also age related. I just turned 50 and mine went up to 48-52. 47-50 was also ‘Excellent ‘.

"Cardio fitness" is more commonly known as VO2max, its the maximum amount of oxygen that your body is able to consume during exercise.

The score is not age related. The score is normalized by dividing the volume of oxygen by your weight. That allows easy comparison between individuals.

Because VO2max decreases with age, the ranges for excellent/good/poor are adjusted for age. In other words, a score of 45 is:

- above average for a 35 year old

- good for a 55 year old

- excellent for a 75 year old

It is age related as I am 14 and mine is 69-73 so yes

It's also sex related as anything above 35 is excellent for a 55 year old.

Ah… to be young again. 69-73. **ahem**

So I’m 48, and currently mine says 60. It used to say something like 56 or 57, but recently advanced…
