BACKGROUND: Although the acquisition of heat acclimation (HA) is well-documented, less is known about HA decay (HAD) and heat re-acclimation (HRA). The available literature suggests 1 day of HA is lost following 2 days of HAD. Understanding this relationship has the potential to impact upon the manner in which athletes prepare for major competitions, as a HA regimen may be disruptive during final preparations (i.e., taper). OBJECTIVE: ), and sweat rate (SR). DATA SOURCES: Data for this systematic review were retrieved from Scopus and critical review of the cited references. STUDY SELECTION: , or SR had to be monitored in human participants. STUDY APPRAISAL: , and SR from the number of HA and HAD days, daily HA exposure duration, and intensity. RESULTS: , but no differences could be established for SR. LIMITATIONS: The available studies lacked standardization in the protocols for HA and HAD. CONCLUSIONS: at a faster rate than HA. HRA may thus provide a practical and less disruptive means of maintaining and optimizing HA prior to competition.
