Karlström after the bronze race: "I lost five kilos"

The interview in the mixed zone said most things, a fully finalized Perseus Karlström met the press.

- The teeth only tingle and the mouth is contracting. I'm kind of close to getting cramps and fainting, Karlström told SVT after the bronze.

And there was justification for Karlström's condition. The pedestrian was part of the IAAF heat study, which has been conducted to document the effect of the heat on selected athletes and the results are startling.

- From start to finish I lost five kilos and my highest measured body temperature was 40.9 degrees, says Karlström in SVT's athletics studio.

Karlström continues:

- It is quite remarkable. There are no athletes who have been up to those levels without having to seek medical care, says Karlström and smiles.
