Hi all,
Have been reading Sally Edwards "Heart Rate Zones for Cyclists" book and am looking for some feedback on orthostatic, or as she calls it - Delta Heart rate, tests.
She specifies the following routine - lay down and measure average heart rate for a couple of minutes, then stand up slowly and continue monitoring until the heart rate settles. The Delta heart rate is the difference between the prone and the standing average. OK, simple enough.
However, if I do a google search for orthostatic tests all the pages I found specify that you should take the reading 15 seconds after standing and subtract the prone average from that figure for your result.
Using Sally's approach, my results for my last 2 readings were 10 and 11, which according to her chart are in the "Excellent, get on and exercise" region.
However, if I use the 15 sec rule, I can see from the heart rate readings I downloaded that my readings are 17 and 25 (the peak of my heart rate jump right before it descends and settles to where I take Sally's readings), which according to her charts would be, "perhaps you should take it easier today".
I have been exercising particularly hard this week and even though I feel great I am now worried that while Sally's readings are encouraging me to get on with my schedule, the other method is telling me it's time to take it easy and let my body recover...
Anybody have any insights or comments?
Many thanks,
Mark
