Acclimation and Acclimatisation of the Equine Athlete

A number of studies have clearly shown that the ability of both man and horses to perform a standardised exercise test in hot humid conditions is reduced compared to that in hot dry or cool conditions (see reviews by Maughan and Lindinger, 1995; Lindinger and Marlin, 1995). In man it is clear that a period of acclimation or acclimatisation is beneficial. A search of the literature prior to 1995 indicates no published information relating to the acclimation or acclimatisation of the horse to hot or hot humid environmental conditions. Concerns for the appropriate preparation for and welfare of horses at the 1996 Atlanta Olympic Games prompted a notable increase in studies relating to equine thermoregulation, and four studies describing acclimation or acclimatisation responses.
