Purpose To characterize the adaptive responses to heat acclimation (HA) with controlled heart rate (HR) and determine whether hydration strategy alters adaptations. The influence of HA on V[Combining Dot Above]O2max in cool conditions and self-paced exercise in the heat was also determined. Methods Eight males (V[Combining Dot Above]O2max: 55±7 ml.kg-1.min-1) completed two 10-day interventions in a counterbalanced cross-over design. Fluid intakes differed between interventions to either maintain euhydration (HA-EUH) or elicit similar daily body mass deficits (2.85±0.26%; HA-DEH). HA consisted of 90 min of cycling in 40°C and 40% RH. Initial workload (172±22 W) was adjusted over the last 75 min to maintain exercising HR equivalent to 65% V[Combining Dot Above]O2max. A V[Combining Dot Above]O2max test in cool conditions and 30 min time-trial in hot-humid conditions were completed before and after HA. Results HR at the end of the initial 15 min workload was 10±5 beats.min-1 lower on day 10 in both interventions (P |
