Heat training could offer same benefits as at altitude

Training at altitude is a popular method for athletes wanting to improve their physical performance as the low oxygen causes the body to produce more red blood cells. in turn these help transport the reduced oxygen around the body more efficiently. This enables an enhanced performance at lower altitudes because the greater numbers of blood cells created at altitude means more oxygen can be delivered to the muscles.


This is the first investigation that compares the effects of heat and low-oxygen training side by side and the findings suggests that heat-based exercise can offer a more efficient means of improving altitude tolerance and physical performance than normobaric altitude training can provide.

“We show that when the duration and frequency of training performed in heat or at altitude are the same, the heat-based training can offer a more obtainable and time-efficient method to improving tolerance to altitude,” says lead author Dr. Ben J. Lee, from the University of Coventry.
