Training in ACSM black flag heat stress conditions: how U.S. marines do it

Abstract

Exertional heat injuries have gained public attention over the past several years, as have the means to prevent and treat them. One of the simplest preventive measures is to refrain from physical training and competition during times of increased environmental heat stress. Unfortunately, this often is not possible or desirable in certain populations. As a result of operational and training requirements, the U.S. Marine Corps and the U.S. Navy medical team have developed an effective exertional heat injury prevention strategy that relies upon education, leadership, and continuous hands-on observation. The fundamental aspects of this approach can be applied to other team sporting activities.
