Trying to understand W5R2 heart rate results
Posted: Wed Sep 25, 2013 8:55 pm
I finished W5R2 today - two 8 minute runs with three minutes walking between.
During the first 8 minute run my heart rate was very steady at 171-173 beats per minute and during the second run my heart rate was also very steady at 172 to 174.
My pace slowed from 5 minutes per kilometer at the start of each segment to 7 min/km at the end of the first segment and 9 min/km at the end of the second segment.
I am a so called "high-beater" with a measured max heart rate of 188, supine resting heart rate of 55 (as low as 49 as high as 60), and a 2 minute active HRRecovery rate of 22 to 29, and Polar fitness index of 39 which at age 61 is supposedly "very good". (The fitness index supposedly correlates to VO2max.)
According to heart rate zone concepts I ran both of these segments around 91% of MHR which is either zone 4 or zone 5 both anaerobic zones. (I felt great afterwards but did need to take a nap in the afternoon.)
It would seem that I will be able to do the 15 minute W5R3 alright, but I'm wondering if I'm actually approaching a lactate wall that is going to prevent me from succeeding in W6-W9.
Are most people doing the program in their aerobic zone? Anyone else using a heart rate monitor?
