Sounds weird but I’ve been sowing slower and easier runs recently and compared to my runs a couple weeks ago which would be 30 seconds+ faster in pace, my heart rate has been higher then those runs. I am running the same distance but much slower, sometimes I’ll go on a run and my hr with lower when I speed up and hey higher when I slow down. Anyone know why this is? I’ve also been running the same route, how long will it take for my heart rate to lower substantially?
Do you use a chest strap or watch monitor? I read online that if you are using a wrist strap, your heartrate might pick up your cadence instead of your pulse. The two matched when I checked them in my Garmin app.
Fixed it somewhat by tightening my watch and ordering a chest strap.
This is a common thread, which was surprising to me. A response on one of them mentioned that higher temperatures increase heart rate.
Yeah, cadence lock is a thing. And a chest strap won't fix it as they are susceptible to it as well.
LRC should have another bot like Trackbot that detects bizarre heart rate reading questions and automatically answers that wrist strap hr monitors are crap.
2 more ideas, let’s just assume the HR monitor is working ok and you can see it go inverse to pace on multiple occasions (not a one off)
1 ) you’ve not spent time at the slower pace and the muscle fibers you’re recruiting are under-trained; you are indeed working harder and your HR is telling you so. This is good news, would mean you have improvement to gain from this work!
2) your form is not as good; you’re not running as efficiently, even though going slower. Recruiting more muscles for lateral motion, stabilization, , slower cadence with longer ground contact, using muscles more than tendons/ligaments for energy storage. This is less good news. You’ll get better/more efficient at slower running by practicing and your HR will drop at that pace, but haven’t really changed your fitness level.
Or a mix.. or something else .
