Influence of Air Velocity on Self-Paced Exercise Performance in Hot Conditions.

Self-paced cycling in still air was associated with a lower Emax and subsequently higher thermal strain, along with a similar or greater cardiovascular strain, despite work rate being lower than in conditions with airflow. The similarity in performance between the 16, 30 and 44 km·h-1 air velocity conditions suggests that airflow ≥16 km·h-1 does not further benefit self-paced exercise performance in the heat, due to modest improvements in evaporative efficiency.
