    Interesting HR observation

    When I'm riding rollers/trainer and maintaining a given
    HR (say 141 ) if I'm on the hoods/dropouts it holds
    fairly stable for a given RPM. If however I sit up
    I notice an almost immediate increase in HR,
    of about 4 - 10 BPM.
    I would have thought that being upright would
    give a more open diaphram, easier breathing etc.
    and not effect HR.
    I'd chalk it upto an increase due to the movement
    of sitting up but it seems to increase and stay at
    an elevate level.
    Anyone else notice anything like this?

    Yep, I've seen that.

    I've also seen that when I hit my upper HR limit on my monitor and then remove one hand from the bar and lower to my side...I'll drop a few beats! I found this by accident as I have troubles with numbness in my hands. Doesn't work all the time, but I've seen it enough to take notice.

    I've noticed that after I hit my max HR and fall off my bike my hr goes down.

    I noticed the opposite - when I go from the bars to the hoods on the trainer, mine goes up 5 bps or so. Mine drops when I go from hoods to bars. I just attribute it to a bit more focus and concentration when in the hoods, although I wonder about diaphram, etc. constriction.

    Some of us are a bit older, and struggle to reach our max HR. but when we do, there is a reason. I have one particular OFFroad hill that takes Bike skill aswell as fitness to get up. I find that due to everyone else failing this hill, I will get my HR 10 above my age max, make the hill and then get off the bike before I fall off. Lying Down of my own free will does not get my HR down. The only thing that does, is getting on the bike, even though Knackered, and spinning for about 2 minutes.
