Earlier in the year, I took an active metabolic assessment test which gave me my training zones as well as my max heart rate of 190bpm.
Most of the people I come across (from Pro level athletes to competitive age groupers) all seem to have the ability to sustain efforts that closely match to their max heart rate but even when I absolutely bury myself, I don’t seem to come close to this number.
For example, during high intensity training and a recent 5k race, my max heart rate during the 5k race was 170bpm and my recent ramp test yielded 158bpm. Adding to this, most of my hr long sweetspot workouts are spent around 135bpm and longer VO2 workout intervals like Spencer and Kaiser max out at about 148bpm. The intensity feels correct but my heart rate tells a different story.
Is there any information to gather based on this analysis? Right now, I’m questioning my ability to really dig deep and keep pushing until I’m at or near max.
