And if you are listening to the drivel on IMLive about larger athletes it is backwards!
The larger athlete does not have a larger area to cool which the body has to work harder to cool it.
The surface area is the cooling system. The larger athlete has a greater mass to cool and has a smaller surface area to mass ratio therefore a smaller athlete can coll more effectively.
Come on this is basics!
Same reason as large deep pie takes longer to cool than a small flat pie.
