"HxC training"
Hardly sounds very scientific or professional. The other labels are misnomers also, for example "cardio training" applies to anaerobic training as well as aerobic, and "fitness/fat burn" applies to all the zones. --85.210.156.35 (talk) 08:06, 18 November 2007 (UTC)

These heart rates are much too low for fat burning, for example. Percentages should refer to Heart Rate Reserve, which is Maximum minus resting. For example, aged 50 with MHR of 170 and RHR of 70 bpm, 60 to 70% should mean Resting Heart Rate plus 60 or 70% of (maximum - resting heart rate), or in this example 130 to 140 bpm. If this graph was correct and it was so easy to burn fat there would be a lot less people waddling to an early grave in our society —Preceding unsigned comment added by 24.108.81.123 (talk) 23:52, 21 February 2010 (UTC)

Is there an error in this diagram?
in I have written:

I think I've spotted an error in the training zone diagram accompanying this article. According to the link link brianmac, a very professional sounding source 70% capacity means the resting heart rate plus 70% of the difference between the resting heart rate and the maximum heart rate; whereas the diagram has 70% capacity meaning just 70% of the maximum heart rate. This means that brianmac has the aerobic zone for a 35 year old (with a 70bpm resting heart rate) between 153 and 163 bpm, whereas the diagram shows the aerobic zone between 130 and 148bpm.

I am considering starting an aerobic exercise program and this makes a big difference, which is the correct zone to use?

please continue the discussion there.

Effectively, the diagram is not correct. It mixes the max heart rate with the heart rate at VO2max. 83.109.24.123 (talk) 23:01, 7 July 2009 (UTC)

In addition, the diagram claims VO2 Max is "Maximum Effort". The VO2 max page clearly explains how VO2 max is in fact the maximum aerobic effort, *not* the maximum effort. Anaerobic effort is greater than VO2 max. 80.229.25.189 (talk) 20:09, 16 December 2014 (UTC)
