Effect of Permissive Dehydration on Induction and Decay of Heat Acclimation, and Temperate Exercise Performance.

ABSTRACT: Purpose: It has been suggested that dehydration is an independent stimulus for heat acclimation (HA), possibly through influencing fluid-regulation mechanisms and increasing plasma volume (PV) expansion. There is also some evidence that HA may be ergogenic in temperate conditions and that this may be linked to PV expansion. We investigated: (i) the influence of dehydration on the time-course of acquisition and decay of HA; (ii) whether dehydration augmented any ergogenic benefits in temperate conditions, particularly those related to PV expansion. Methods: Eight males [VO_2max: 56.9(7.2) mL·kg^-1·min^-1] undertook two HA programmes (balanced cross-over design), once drinking to maintain euhydration (HA_Eu) and once with restricted fluid
