Abstract
Abstract Long‐term heat acclimation has been shown to elevate haemoglobin mass (Hb mass ) and enhance maximal oxygen consumption (). To date, however, all evidence derives from exercise‐induced heat stress, making it unclear whether passive strategies, which allow athletes to maintain training intensities, can produce similar adaptations. Moreover, while heat‐induced increases in are often attributed to haematological changes, adaptation of other convective components of oxygen transport may underpin these improvements. To investigate whether 5 weeks of hot‐water immersion (HWI) would enhance
