This month I did much zone 2 and I found that my heart rate and power is linear correlation. The R-seq is so high that I thought I can only find it in my statistic textbook.
Does it mean I am using fat rather than carbohydrate? Do anyone have the same trend as me?
The linear relationship between HR and Power exists for everybody in the aerobic range. Between LT1 and LT2 is all aerobic and called Zone 2 in a 3-zone system. In a 7-zone system, this is Z2 to Z4.
Your high-end power looks pretty good, depending on your body weight but your low-end power is doubtful. It depends off-course on your HR zones and resting HR but for most athletes, 100W at almost 130bpm shows lack of low-end endurance/capacity. Well trained riders with power values of 250W or more at the high-end aerobic range, ride 100W well below 100bpm.
The only way to improve that, is to ride a lot at low intensity. if you keep riding constantly in Z3 and Z4, you will quickly burn-out and fatigue. Worst case scenario is an injury by overloading.
Thank you for your reply. It is really helpful.I think you are right that I need do more low intensity ride.
I just have a question. my eFTP is 240w, so I would ride at 140-180w as my Zone 2 exericise (for around 2h), while the HR would be 140-150 bpm. Do you recommend to ride at a lower power?
Do you know what your max HR is?
I don’t know, but I can reach 180 at my interval training. So I guess maybe 180 to 185?
And my resting HR is 45-50.
Low Intensity training is best done by HR. You obviously look like someone starting out his journey in the endurance training world.
The shocking advice would be to do 90% of all your training with a max HR of 180 minus age.
For the remaining 10%, use power to target intervals.
Yes, actually I just started my training few months ago and bought a power meter last month.
I will reschedule my plan based on my HR. Thank you for your advice.
