Heart rate training - some numbers

In my last post I mentioned I would include some figures so some of this may make some sense. These values are used by my heart rate monitor in it's calculations.

So as of today, 23/7/2012:

  • Age: 29
  • Height: 1.87m
  • Weight: 85Kg
  • BMI: 24.31
  • VO2 max: 51*
  • Resting heart rate: 42 (averaged over the last couple of mornings. I have seen my heart rate drop to 39 before, which was a little freaky)
  • Maximum heart rate: 170 (I tested this tonight by sprinting up a hill out of Durham Chare on my commute home and then checked my Polar training diary over June and July and then averaged the maximum readings out.)
*VO2 max is measured as"milliliters of oxygen used in one minute per kilogram of body weight" I calculated it using this formula and is not a 100% precise measurement.

I'm pleased that my BMI and VO2 max are in the right areas of the table, although I have put on around 4Kg. I don't know when, it's been that long since I checked.
