Calories burned while rowing

(Jon Isaacs) said:

The sweat mechanism is designed to cool the body like a radiator cools the body.

This is not quite right. Unlike an automobile radiator, which is a simple heat exchanger, the sweat
mechanism relies primarily on water's 540-calorie-per-gram latent heat of vaporization. Were it not
for the cooling caused by evaporation, we could not cool ourselves when the ambient temperature was
greater than body temperature.

ex. Typically I might do 1000kJ/hr accorinding to my trainer. If efficiency is 25%, and there are
about 4 kJ in 1 cal. I'm burning 1000 cal/hr.

I could see a rower buring about the same number of calories in an hour, but not say two times
more, which is why I think the figure above is the approx. total energy used.

This would seem to fit: 1:57 for an hour is about 1150 calories according to a Concept 2.

So what is your efficiency and how did you measure it?

I measured how much work I did and how many calories I burned doing that work, and I
divided. Simple.

Ah well, it only ever did work well in one direction. No nagging mechanism to stop you eating too
much as there is for eating too little. Could you find one person - apart from perhaps Callista
Flockhard (sp?) - where this doesn't work.

My hungry/full indicators aren't very accurate, so I have to eat before I'm hungry and keep eating
after I'm full. It must be genetic, since siblings have the same "problem".

5' 11", 135 lbs. Most people would consider that thin. It certainly makes climbing easier.

I have a calorie burn question.

I've been using a Polar 720 heart monitor, which produces a calorie estimate for each workout. I
find it handy, since it gives me an idea of how much to eat that day.

Most people have bodies equipped with hunger mechanisms that calculate how much exercise you've
done, how many calories are in your food, allowing your body weight to stay pretty much the same
no matter what you do.

Most people also have bodies equipped with fatigue mecanisms that will tell them when their heart
rate is to high, yet we still find that we need heart rate monitors; these mechanisms simply don't
work to perfection..

If I do say 2 hours my body has done the calculations and cries out until for more until I have
taken in the appropriate amount of calories.

Who is this "we" that "need heart rate monitors"? Having used them for a couple of decades or so
with athletes of various standards, I find them a distraction and relatively useless as a
coaching tool...

I found that I can guess my LT a whole lot more accurately than I can lower levels. Heart rate
monitors aren't necessary for those hard days though it can give information on whether you are
beginning to overtrain. They are most useful in showing you that you are working to hard on your
easy days.

I agree with this on the proviso that they are necessary to develop the "feel" for the right
training levels. After you know how to train you don't need heart rate monitors and you should also
drop bike computers as well. That is also a distraction that leads to you trying to go too hard on
easy days.

During a very difficult interval session last Wednesday, I felt a new pressure/pain in my chest. It
went away after I immediately backed off on the effort.

Is this the kind of mechanism you have in mind or was there another that I should have listened to
first? (I apologize if this is over the line of asking for medical advice on the net.)

Not the kind of mechanism I had in mind, and definitely not normal - you should follow up with a

If I had insurance, I would. As it is, a web search indicates that the pain I felt was not all that
unusual. I believe (hope) that I did nothing more than temporarily fail to meet my heart's oxygen
needs. It was a REAL hard session, and I was pushing my hardest at the time.

Last I checked, a few years ago, it was just shy of "high." If I drop off the net completely in the
near future, at least you all know why now. :-)

I feel pretty safe. I don't know if I've EVER worked my body/heart as hard as I did last week
when this happened. I don't need to be pushing my max that much, having achieved an acceptable
level of fitness.

But perhaps I'll go to the local sports science academy and have a maximal heart rate test done.
That's pretty cheap.
