Too much cardio... (Read 2528 times)

Without googling:

Did you have to say that? I get it. I'm uncultivated.

Knowledge of inane facts is like the opposite of being cultured.

No. We were talking about calories.

I was having a sidebar conversation with mikeymike, who seemed to indicate that running economy either did not exist or did not have a significant effect on running fitness, which is the discussion that the thread devolved into when you were gone.

RunningBehind, my only argument is with whether any of this has to do with caloric expenditure rates over distance. Not with oxygen consumption, stride efficiency, etc. And I am not arguing against Noakes and Daniels (who themselves argued against each other).

And my argument is that oxygen consumption and stride efficiency are directly related to caloric expenditure. Caloric expenditure is the measure of energy used, an efficient runner will require less energy to produce the same unit of work as a less efficient runner. If running economy has no effect on energy cost, there is very little explanation for the effect that running economy has on running pace. We know that "easy" pace for casual and elite runners recruit the same physiological systems, but with energy cost out of the picture, it's hard to explain the difference in pace when we are talking RQ<1 (and thus lt and vo2max have insignificant effect) intensities. btw: i didn't do the stride experiment, but it was hot as balls outside which is another thing that can effect running economy.

You can take lots of small steps or fewer longer steps without appreciably changing your vertical lift.

Can you explain how this is possible? Don't you have to jump higher in order to jump further, assuming horizontal speed remains constant?

It was pretty warm. Not quite the 96 degrees you imply, but pretty warm nonetheless. Where in TN are you?

Apparently you burn more calories running than you do typing shite into t'internet.

The point is, calorie expenditure while running is a function of body weight, distance covered and individual intrinsic variation. ALL other factors, including efficiency, ambient temperature, windspeed, road grade, etc, are all insignificant next to the confidence interval around intrinsic variation.

Trent, this can't possibly be true. Try running a mile on a flat road with no wind. Then run a mile up a 30% grade with a 60 mph headwind. You're saying you will burn the same number of calories in each case? Also, where are your references? I want to read the scientific literature that supposedly confirms your statement. Yes, I'm grumpy because my mom bailed on watching the kid this morning, so I'm sitting here instead of running.
