In our latest study published in the European Journal of Applied Physiology in September 2019, we report that VO2max in thermoneutral environments can be enhanced following a bout of heat acclimation. Crucially we report that future research should take care when testing athlete post HA as residual fatigue may blunt the maximal responses that can be achieved and that on average confirmatory tests should be performed at least 96hr following the final bout.
