Re: Larger Athletes & Heat - Physiological Reason Why? [Mike Alexander]
Low surface to mass ratio - therefore the ability to shed heat via blood flow to the surface or by sweating is decreased.

Frodo might be tall but he is lean...he has decreased his mass but his surface area remains relatively stable. He could gain 20 pounds of muscle mass and not add much surface area (hence lowering ratio)

I am 6'2 and 195 pounds with 9% body fat at the moment. I raced my fastest - running not triathlon - when I was 173 pounds. I felt weak at less weight and heavy at more. I also race and train in SW Florida - or as I like to call it - the amazon jungle.


Im sure someone can shed WAY more light on the principle but this is what I gathered when I tried to figure out why my out of shape 5'4 buddies didnt die in the heat and I did
