Caloric expenditure - Jogging vs Walking

[Mudge]

The argument came up again on another board as to this being linear per mile based on distance (or speed) no matter how you got there running, or jogging. This goes against the most elementary laws of physics, where friction and gravity are reality.

Walking (2 mph) 198
Jogging (6 mph) 654

Here is an example of non-linear expenditure:

I've never understood any of these arguments anyways. I remember watching the news and some jackass nutritionist was explaining how you could lose like 20lbs a year if your regular morning coffee had cream in it and you stopped putting cream and sugar in your coffee. Your body is too smart, it will always adjust.

That being said, there are other problems having to do with jogging vs. running and total caloric expenditure, the anaerobic component of jogging. Look at interval training, it has been shown to be the best as far as fat burning, and it incorporates anaerobic with aerobic.

Yep I wont argue there (HIIT), simple physics though shows that an argument that distance is the only factor is just ridiculous.

If we look at biking which is the same activity where as jogging and walking are NOT the same activity, we only have a difference of inneficiency of the body itself.

13MPH/5MPH = 2.6

2.6*174 (5MPH biking) = 452 calories

Where supposedly 612 calories are burned per hour @ 13 MPH. So we see again, nature is not linear. To believe otherwise is to deny science itself, we do not live in a damn vacuum, we do not live in a world without friction. We are not perpetual motion machines.

You dont get something for nothing on planet Earth. Just as in my so called "non-scientific" example of a car requiring approximately 5 times the horsepower to go 200 miles per hour versus 100 miles per hour.

For anyone living in the past, I'll be burning witches at noon if you'd like to send some my way. Bring your own hot dogs and beer!

You could build a bridge out of her.

It's frustrating 'discussing' issues like this with somebody who only knows what they've read and won't actually think about anything.

Its a neat idea and all but we live on earth, without a vacuum and without gravity. If you do more work there is always increased cost, I can't think of an example this is not true unless we talk about engines being very innefficient at very low RPMs.

A car made do 100 MPH with 100 HP, but it will take about 500 HP to get the same car to 200 MPH. Another example of real world resistance, obviously different but whatever.
