Hi Reed,
Thanks for the advice.
With regards to some of the points you make, the test did involve a gradual increase in speed and incline on a treadmill however we had to change the HRM due to the fluctuations in heart rate, so that would probably account for the early discrepancies in HR figures you noticed.
Also I only did a very quick warm up as we were pressed for time so the more I think about it the less I should pay attention to the results.
I think I’ll look into the HR drift test Scott suggested and see what that comes back with.
Many thanks to you for your help (and you too Scott 🙂 ), much appreciated.
Regards
Craig
