calories

 hi guys,

im in the forces and go alot of "tabbing" basically alot of running with a heavy bergan/rucksack on my back.

it usually involves fast marching followed by a min or two of "doubling" a steady jog.

then repeated for around about 10km in 1hr 15mins

now, my question is how many calories will i burn?

im 176cm

75kg

and my pack weighs 25kg

Weight in pounds x distance in miles x 0.57 for walking at a good pace on the flat....

Re: calories

Wouldnt all this vary depending on how fit you are, the terrain, weather & differ from person to person aswell?

Re: calories

I think on the whole, the laws of physics being what they are, probably not much in it. It takes X amount of energy to move a given mass a given distance or height. Obviously a big headwind would make a fair difference, but then if it was headwind out and tailwind back it'd probably average out.

The equation I gave was only intended as an approximation. Maybe I should have said..

I wasnt doubting the equation as such, but just adding that a 1ltr engine works harder than 2ltr engine to tow a heavy load......

Re: calories

Yer absolutely right, but the 2 litre has more power available so the power to weight ratio favours the 2 litre.

I don't think it reads across to people in the same way. But (and now I AM possibly on shaky ground)

If I were to race a top athlete over 100m he'd eaaaasily win. I think we'd broadly consume about the same amount of energy but the burn rates would be different. But essentially we both move the same weight over the same distance so burn (roughly) the same amount of calories. I think.

Re: calories

Assuming you're aged 18-30, at 75kg your Base Metabolic Rate is 15.1*75+692=1825kcal/day, which is 76kcal/hour. Multiplied by a Physical Activity Ratio of 6.9 (vigourous exercise, eg carrying a load uphill) this is 524kcal/hour. So for 1.25 hours this would be 655kcal. Given the weight you're carrying I would guess that your actual expenditure would be somewhat higher, maybe in the range of 700-800kcal.

Re: calories

There should be some sort of 'rhyme' to help out with this, but I don't know any nor can I make one up since the only word that I can find that rhymes with calorie is Valarie!

Re: calories

These numbers look a little difficult, so I may need a Mars Bar to work them out.
