Muscle strength is based mostly on length of muscle, not mass of muscle. When you double a creatures height and keep every proportion the same, muscle strength increases by a factor of two, bone strength increases by a factor of four (cross-sectional area), and weight increases by a factor of eight. This is why you can't just increase or shrink the size of normal animals and get a creature that can actually survive well.Gort said:Common sense. They're tiny and aren't built out of hydraulic presses. The tiny size of their muscles means they should be weaker than races with human-size muscles. The same reason housecats should have lower strength than humans.
To be honest, I think they're pushing it with elves having the same strength as humans, when on average they're about 100 pounds. (considerably lighter than the average modern human, who come in at 175 pounds, but I suppose you could shave some of that off for a medieval human)
If you were at an arm-wrestling match (or any test of strength, really), and a 65-pound, four foot tall guy was squaring up to two six-footers, one a six-foot shrimptoast of 100 pounds and the other a beefcake of 150, you wouldn't think they were equally likely to win when you were placing your bet.
Too closely tying strength to weight or height is a flawed way of looking at things. Elves may be lankier than humans, but that should not affect muscle strength at all, since their height is pretty much the same as that of a human's. At the same time, Halflings may be much shorter than a human, but it results in a smaller decrease in strength that one might think, especially with the tremendous decrease in weight freeing up a lot of potential muscle power.
I think you are just confusing the differences between individual humans (developed muscle vs. undeveloped muscle) and the differences between different species (entirely different muscular and skeletal structure).
