Dans cette quête vers les sommets... du podium, il est secondé par des champions de la science : physiciens, biologistes, ingénieurs et même mathématiciens travaillent à comprendre et adapter la physiologie des sportifs pour optimiser les efforts et les performances de ces derniers, qu'ils nagent, roulent, courent, lancent, soulèvent...
