Any help would be appreciated
Hi,
I have a similar experience - when I work out for 30-45 minutes on my rollers, my heart rate will continue to ratchet up. At the end of my work-out my overall average HR is higher than I would see for riding outdoors (in comparison to something like a club ride).
I put this down to three factors -
a) on the rollers, I'm often doing more structured work-outs which are more compact than I do outside. For example, shorter warm-up and warm down times, intervals. So I'm packing more work into my time on the rollers so my avg HR is higher.
b) connected to last factor - there is more recovery time when I ride outside which pulls my average HR down. For example - work hard to climb a hill then take it easy on the way down, sprint for a marker then soft pedal to recover, slow down in preparation for a big climb, stop signs, traffic lights
c) its hot! even with a fan on me, it gets hot on the rollers and you don't have the wind to cool you down like outside. Might add a few beats to your average HR (this is conjecture - I don't have any empirical evidence to back this up)
If I did similar work-outs outside as I do inside then apart from factor c) I'd expect to get similar heart rate readings.
take it easy.
