An experiment was conducted by a group of Scandinavian scientists in regards to exercising in dry heat conditions. C. X. Munoz, K. R. Carney, M. K. Schick, J. W. Coburn, A. J. Becker, D. A. Judelson designed an experiment in which ten men between the ages of 18 and 35 were tested for a variety of variables during dry heat conditions. The purpose of the experiment was to see if combining drinking water with externally cooling down the body-by pouring water on oneself- would affect the perceptual and performance levels of the subjects. The four males walked for 90 minutes at 30% VO2max and then ran a 5-km time trial in 33 C and 30% relative humidity. The tests measured oral rehydration (OR), external cooling (EC), and oral rehydration plus external cooling (OR + EC). The experimenters measured rectal temperature, skin temperatures, heart rate, thirst, thermal sensation, and ratings of perceived exertion (RPE).

Drinking water and combining it with external cooling will reduce the skin and body temperature during high levels of exercise. Doing that during dry heat conditions might enhance performance during high intensity exercises. Some endurance athletes have said that combining drinking water with external cooling helps with the rise in core temperature, decreases perceptual strain, and improves performance. Munoz (2012) suggests that recent research has shown that high skin temperature might negatively affect aerobic exercise performance in hot, dry conditions. Therefore, external cooling might contribute to improved physiological and psychological performance during exercises in the heat. The expectations for the results are that these suggestions are proved correct and that high intensity performance will improve during dry heat conditions.
