So it’s pretty common knowledge that you have different max heart rates for different sports - running and skiing are higher than cycling, which is higher than swimming.
I’m assuming that running and skiing have a higher max possible heart rate because you are utilizing more muscle fibers in your arms and core.
Would this assumption apply to cycling max heart rate in the saddle vs. out of the saddle? I would assume that standing you should be able to achieve a higher max heart rate than seated because your arms and core are more involved than when you’re seated.
WRT polarized training - I find that my max heart rate efforts all come from out of the saddle efforts. Should I use a lower max heart rate to determine goal workout efforts if my assumption about different cycling modalities is true? I find that my ramp test max heart rate is MUCH lower than what I get from efforts on hilly group rides where I’m out of the saddle.
I’m curious to hear if those who have done heart rate max tests seated vs. standing and if there is a variance between the two.
