Heart Rate Lower Using Bike Trainer?

Quoted message said:

hi, wondering why it would be that my heart rate is always
significantly lower when riding the bike trainer than on the road? i
would think that given the same effort they would be the same. i can
do a time trial workout on the trainer full effort, yet it's about 20
beats per minute lower than my HR doing the same workout on the road.
any thoughts?

Mine is always lower on the trainer too. And when I take a spin class
my average HR is usually lower.

I think with me, I just don't put out as much effort. When I'm out
riding, I can't back off on a hill. And when riding into the wind, I
have assert as much effort as is needed.
At home or the Y, I think I self regulate. Although at the Y, My rate
does get up there on spin ups and real high cadence spinning, like
120-130rpm.

In your case, it may be the actual conditions of the road, wind,
rolling resistance of both front and rear tires. Anyway, that's my
guess.

Life is Good!

Must not be full effort.

Riding the road is more fun, interesting, and risky.

Perhaps your limited by heat dissipation on the trainer.

Impedance to riding indoors as intense as outside

1) Abnormal and minimal stimulus or feedback from your exertion. The
most noticeable thing is the tension on your muscles as you exercise
but there is very little payoff to focus on and to align your effort
with that of your outdoor rides.

Fix: use a power measuring device or look up the resistance curve for
your indoor trainer / device. Keep shifting and spinning until you
reach a comparable level.

Note also that with less inertia, it is more difficult to keep the
tension up on your muscles. If all you have is a cadence and HRM, keep
working on smooth spinning higher and higher until you get to your
desired range. Over time, you will find it easier to pedal at these
rates with less conscious effort. Whenever I transition indoors for the
winter (rainy days) it takes me 4 to 6 weeks for me to be able to hit
my targets without an annoying level of conscious focus.

2) If and when you do start to work closer to your outdoor effort, heat
will become a problem that needs to be dealt with.

I use a 24 " fan and ride in an AC'ed room. If you only have a small
fan, I find that pointing it at the head is the most efficient way to
assist your body in keeping temperatures down. Also, the right kind of
fabrics that wick sweat away will help you stay cooler, it keeps levels
of sweat closer to ideal vs. exposed skin. A fan on your legs is a
luxury (in case intuition leads you there, it is not that effective)

Also try intervals to help bumping up your level of inertia and average
effort while you are still building the mental tools to hit your
targets. If you are properly cooled, there is no reason you would not
be able to work at the same levels as outdoors. I feel like I am
forgetting something...If you have trouble, build your average with
contiuously longer intervals and work on keeping cadence up. Indoor
training with rollers or any other cycling hardware is great for
working on smooth pedaling. You can hear the smoothness of your efforts
if you pay attention. That reminds me, music, TV or anything that helps
you get motivated to replace the normal outside stimulus email
questions are ok.

How do you know that the riding is at the same effort?

This is probably the answer right here. As unreliable as HR is, I just
don't see how a (say 300 watt) Powertap reading would result in a 20bpm
difference between indoors and outdoors.

Maybe, maybe not. Some guys can do slightly more power outdoors than in,
others can do slightly more inside than out. That's measured using a
PowerTap on the road and on the trainer. So my question was a real one:
how does he know the effort was the same?

I guess no technical way to know........though even at my "cruising"
easy efforts my HR is lower on the trainer than outside. I am well
cooled by the fan too. My legs actually feel closer to "failure" doing
an inside time trial than doing an outside time trial, yet the HR is
way lower..........just seems odd that I can do a 30 minute TT on the
trainer, going as hard as possible, yet barely hit 140bpm. Maybe I
just have a crappy bike trainer!
