Investigate the effectiveness of short-term heat acclimation (STHA), over 5-days (permissive dehydration), on an intermittent sprint exercise protocol (HST) with females. Controlling for menstrual cycle phase.    Materials and Methods  Ten, moderately trained, females (Mean [SD]; age 22.6 [2.7] y; stature 165.3 [6.2] cm; body mass 61.5 [8.7] kg;V  .   ⁢   O    2   ⁢  peak43.9 [8.6] mL⋅kg –1 ⋅min –1 ) participated. The HST (31.0°C; 50%RH) was 9 × 5 min (45-min) of intermittent exercise, based on exercise intensities of female soccer players, using a motorized treadmill and Wattbike. Participants completed HST1 vs. HST2 as a control (C) trial. Followed by 90 min, STHA (no fluid intake), for five consecutive days in 39.5°C; 60%RH, using controlled-hyperthermia (∼rectal temperature [T re ] 38.5°C). The HST3 occurred within 1 week after STHA. The HST2 vs HST3 trials were in the luteal phase, using self-reported menstrual questionnaire and plasma 17β-estradiol.    Results  Pre (HST2) vs post (HST3) STHA there was a reduction at 45-min in  T   re   by 0.20°C (95%CI −0.30 to −0.10°C;  d  = 0.77);T  ¯    s  ⁢  k(−0.50; −0.90 to −0.10°C;  d  = 0.80); andT  ¯   b(−0.25; −0.35 to −0.15°C;  d  = 0.92). Cardiac frequency reduced at 45-min (−8; −16 to −1 b⋅min –1 ;  d  = 1.11) and %PV increased (7.0; −0.4 to 14.5%:  d  = 1.27). Mean power output increased across all nine maximal sprints by 56W (−26 to 139W;  d  = 0.69; n = 9). There was limited difference ( P  > 0.05) for these measures in HST1 vs HST2 C trial.    Discussion  Short-term heat acclimation (5-days) using controlled-hyperthermia, leads to physiological adaptation during intermittent exercise in the heat, in moderately trained females when controlling for menstrual cycle phase.
