DESCRIPTION:Life history theory predicts the existence of trade-offs betwe
 en competing physiological functions relating to reproduction\, maintenanc
 e\, defence\, growth and storage under conditions of limited environmental
  resources. This results in an individual may allocate energy to traits en
 hancing fertility or invest in traits enhancing survivorship. \nDespite th
 e intuitive appeal of a stereotypical trade-off featuring a negative relat
 ionship between two traits\, such negative covariation of traits are frequ
 ently absent when phenotypic comparisons are made between individuals in a
  population. Research within the ADaPt Project uses ultra-marathon competi
 tions as quasi-experimental scenarios intended to induce an energy deficit
 . This allows negative correlations to be observed\, enabling study of hum
 an life history trade-offs. Here\, I will discuss our analysis of athletes
 ’ physiological response to competition across a range of extreme enviro
 nments\, and present the findings of previous pilot work.\n
