The human body functions inefficiently during exercise and, as a result, between 70-80% of energy produced during exercise is lost as heat (Marino, 2002) causing strain on the thermoregulatory system. When performing high intensity exercise in the heat, such as that experienced during team sports, the strain on the thermoregulatory system is increased, resulting in core body temperature exceeding 40°C, and a decrease in exercise performance (Nybo and Nielsen, 2001). Consequently, various cooling methods have been examined to try and improve performance (Marino, 2002). Hand cooling is a practical method of reducing the onset of heat strain (House et al., 1997) due to a large number of capillaries in the hands that can be exposed to the cold when submerged, leading to cooling of the blood and consequently core temperature (Livingstone et al., 1989). However, the effectiveness of hand cooling has not yet been reported during intermittent exercise to alleviate heat strain. Therefore the aim of this study was to determine the effects of different hand cooling regimens on intermittent exercise performance in the heat.
