Females achieve physiological adaptations to heat adaptation regimes, including a reduction in resting and exercise core temperature, skin temperature, heart rate and an increase in sweat rate, but no change in plasma volume.

Performance test outcomes, including mean power and time to exhaustion, are improved in females following heat adaptation regimes.

Physiological adaptations were more consistently observed in heat adaptation regimes across all moderators when utilising durations of 451–900 min and/or 8–14 days of heat exposure, exercise intensity ≥ 3.5 kcal.min−1, TEE ≥ 3038 kcal, completed via a consecutive (daily) frequency and total heat dose ≥ 23,000 °C.min.
