Is it just me or is this pervasive among my brothers?(9 posts)

Is it just me or is this pervasive among my brothers?eschelon

Is it only me? Everytime I ride my indoor trainer and try to sustain a ~155 bpm, I feel like I am trying to kill myself for 2 hours...and so consequently in order to sustain a good cardiovascular workout on my indoor trainer, I have to maintain a heart rate of ~120 bpm.

But when I am riding outside, if I ride at ~120 bpm, I would probably fall asleep from the boredom and lack of intensity. And so consequently, I am easily able to maintain ~155 bpm for hours and miles and miles outside.
me too. different numbers, same results. who knows?!? nmJS Haiku Shop

do you use a fan?lonefrontranger

Cardiac drift can be caused by many factors, and in this case it could be overheating. You should always use a fan and/or ride someplace cool like unheated garage or basement.

There are other factors. You may simply be energized and adrenalized more by riding outdoors. I know my HR averages about 5 bpm higher in a group ride, and 10 bpm higher in a race, regardless of perceived effort. I chalk this up to adrenaline. Next year I plan to have a power tap/wattage meter of some kind to use during training so I can more effectively measure this.

For what it's worth, I can't ride rollers anywhere below 125-130 bpm. They make me too nervous, even tho I'm pretty skilled at it and have been riding them for ten years.
Have you taken into account that the rollers/trainerLone Gunman

is a constant effort with a much higher rolling resistance and the effort indoors must always be the same/constant to sustain that 155bpm effort? It is 2 differnet animals, and I feel I work harder on the trainer/rollers than I do out on the road although the HRM says differently. You get that break of coasting less effort on a downhill setion and don't have to pedal as hard to continue the pace as on the trainer.
It's the higher end efforts that I have trouble obtaininggreg

To do an aerobic ride on the trainer isn't much of a problem for me. Although like you said, it is harder because of the constant pedaling. But my problem is reaching readings around my LT. I can get there no problem outside on the road, but like last night, I was supposed to be up around 175 for the hard efforts, and I didn't get much above 165. Overtrained, no. Lack of sleep/tired, yes. But this happens consistantly when I am supposed to be around LT or above indoors.
Same, LT about 166 inside, 176 outside. . .js5280

Never quite understood why there was difference, I do have a fan going sometimes so I don't think that's it. However I doubt the fan blows 17-18 mph which is my avg. riding speed outdoors. So maybe the extra forced air intake allows you to push a little harder. . .
If I remember correctly, it's the same with me. [nm]Elefantino

One possible reason...Bruno

is that when actual riding you are using the muscles of your back, arms and neck much more. This could account for 5-10 bpm more than at the trainer. It also happens to me but I believe that the percertion of effort is different because when indoors I am focusing on the pain and outdoors I am focusing on the car that just past me 5" away at 50 mph.
