En annan studie påpekar skillnaden i värmeförluster pga olika längd:
"Two runners of the same mass and a 30 cm (12 inches) height difference would have a difference in body area of about 15%. If the height difference is only 1.5 cm (6 inches) the area difference is still about 7%. Thus an ectomorphic runner has considerably more body area from which to lose heat compared with a shorter runner of similar weight.
The tall ectomorphic runner is further disadvantaged in two ways. Firstly, he will probably have less insulating subcutaneous fat than more balanced physiques. Secondly, lung size is correlated positively with height (Cotes, 1979) and the taller runner will probably lose more heat from the lungs by vaporisation and radiation than the shorter runner.
In weather conditions predisposing to hypothermia first aid workers should be particularly wary of the slow, middle-aged, ectomorphic runner who becomes a casualty. The factors discussed above may operate to the runner''s advantage in hot conditions."
Apropå det sista stycket, tillhör ju de äldre, långsmala och långsamma.
Bara att invänta och omfamna värmen när den kommer. :)
