Long limbs? Short limbs?

After reading the “Chinese and sports” post, I just wanted to ask how does one define ‘long’ limbs as opposed to ‘short’ or ‘medium’ limbs? Obviously, if your knuckles drag along the ground when you walk, you have long limbs in the arms and short limbs in the legs. I’m talking about when it is less obvious… Is there a measurement system out there to determine this?

I think average proportions for arm length is mid-thigh. So I guess if your arm is longer than mid-thigh you have long arms, if they are shorter than that you have short arms.

managing the training of weightlifters has some stats. i am goin home soon so maybe ill post them when i get back

Any information about limb length of legs?
