Here is a study for those of you out there who like to run races in the heat. The scientists measured how drinking "ice slurry" (the scientific term for slushie) affects one's ability to run hard in hot temperatures (34°C or 93°F). Not only did drinking 2-3 cups of slushie reduce the runners' rectal temperatures while running (!), it also allowed them to run longer when compared to drinking cold water. But if eating ice-cold ice slurry gives you headaches, fear not! Other studies indicate that taking a nice freezing ice bath works just as well. Because that sounds fun.
Ice slurry ingestion increases running time in the heat. "OBJECTIVE: To examine the effect of drinking an ice slurry (slushy) compared with cold water on prolonged submaximal exercise performed in the heat and on thermoregulatory responses. DESIGN: Crossover trial, with the 2 conditions counterbalanced and in ...
