My first post here to Uphill Athlete, so first I want to thank Steve and Scott for putting this together. I’ve enjoyed reading TfTNA, and will probably reread it again in the near future.
I am trying to get some insight about my physiology with respect to HR. I’m 36 and have been active my whole life. I’ve actively trained in the past, however schedule and some health issues have prevented me from exercising near as much as I usually do (let alone train) the last 6 months or so. I still try and get out and skin up the local ski hill once a week or so, which gives me a couple thousand vertical feet, but the last few times I seem to be getting worked..
Yesterday, I went out and did a long hike with my partner. Lot’s of vertical (~3200ft up/down with a few miles of level ground in between). Usually this hike wouldn’t be too stressful, and I would come out of it without too much of a problem. Yesterday I noticed that my heart rate high though. Based on previous evidence, I thought my maxHR was about 190. Yesterday, hiking out(up), I was averaging HRs in the range of 182-187. I stopped and took a break, and when I returned to hiking, the average lowered about 10bpm for what seemed like the same exertion level. I wasn’t carrying much in the way of extra weight, but was moving at a semi fast clip (maybe 2.5-3mph). I wasn’t gasping for air, and was on the cusp of where I could breathe out of my nose, but was generally breathing out of my mouth.
My question is, is it reasonable for me to have such a high sustained HR (compared to what I thought my max was) for such an extended amount of time (2 hours), even though I wasn’t gasping and was able to sustain the pace for a decent amount of time?
Other notes: I was consciously staying hydrated, meaning I was sipping frequently. I was sweating quite a bit. Temperature was moderate (~70F). Hike down was in the sun, hike out was in the shade. We ate lunch about 40 minutes before the climb out.
