Title: Does size deduce energy expense ?
Post by: neilep on 26/04/2006 19:38:02

Do people of different weight/size but of equal fitness expend the same energy when doing the exact same exercise ?




Men are the same as women, just inside out !

Im pretty sure that the more fat you have on your body, the more calories you will burn irregardless of your fitness level

I too would think that the greater the weight the greater the effort and therefore you burn more energy.

What you do speaks so loudly that I cannot hear what you say.

Hi neil nice to see youve recovered.

I would have thought their could be many different things which could affect the results, possible examples below.

what type of foods they've eaten beforehand

Does one of them smoke.

Size and efficiency of the muscle group doing the work.

Muscle memory, is one of the people more used to do a particular exercise than the other.

Are they having to carry their own weight as they exercise.

who has had the most punishing day before their exercise session.

not being sexist, but i think whether u are male or female would affect your energy expenditure. i am only 5ft 2 and 48kg, but i burn off at least twice the calories of a man twice my size due to my disease, cystic fibrosis, so i think general 'size' has nothing to do with it. my brother was the same height and weight as me and he was always able to lift and run more and faster etc.

i think you are all missing the point of neil's question.  

assuming that ALL other things are equal (sex, health history, diet, etc, etc, etc) yes, a person who weigh's more will use more energy doing the same exercise (because they have more weight to move in doing this exercize)  this goes for both weight from fat AND weight from muscle.  weight is weight.  The reason we think of the two differently, is because the muslce mass actually helps you with the lifting, so it doesn't require as much precieved exertion, however, that same amount of weight is being moved/liften regardless of what its made of, so the same amount of force is required and thus the same amount of energy must be used (again, assuming as neil stated that they are both of the same fitness level)

Are YOUR mice nude? [;)]

Thank you all for your replies and thanks also to Justin(Mayonnaise VenusFLYtrap Farmer) for assuming correctly.

My apologies if I did not make it clear..however...everybody really came to the same conclusion anyway that 'weight' matters...


THANK YOU L...big hugs and shmishes to woo all !!
