Study note

Training wearing thermal clothing and training in hot ambient conditions are equally effective methods of heat acclimation.

What the study found

All three heat-training groups improved their thirty-minute cycling power in the heat, with no significant between-group differences in the reported measures.

Participants and protocol

Thirty-four cyclists completed ten days of training in a hot chamber, thermal clothing, or thermal clothing combined with hot-water immersion.

What this cannot establish

Failure to detect a difference does not establish identical effects or safety for everyone. These controlled protocols do not justify unsupervised overheating or guarantee a similar improvement.
