Cold water ingestion ameliorates increase in core temperature and discomfort during simulated motor racing in a hot environment: a randomised trial

Abstract

Introduction: Formula One drivers race for prolonged periods (>90min) in hot conditions, wearing protective apparel that impairs heat loss, thus are at risk of prolonged elevated core temperature. Ingestion of cold fluids has been shown to be beneficial in endurance activities such as running and cycling. This study aimed to determine whether the voluntary ingestion of cold fluid aided thermoregulation more effectively than the voluntary ingestion of ambient temperature fluid in a simulated motor racing environment.
