Ice slurries are icy mixtures that are consumed as a drink, and many studies have reported that ingestion before exercise improves exercise performance. It is thought that when sports drinks are ingested in the form of ice slurry, carbohydrate and electrolyte intake can be achieved in addition to water intake and body cooling, thereby a greater ergogenic effect can be exerted. However, there are no studies that have investigated the difference in the composition of ice slurry. Therefore, the purpose of this study was to investigate the effect of the difference in composition of ice slurry on endurance exercise capacity in a warm environment. Eight male participants ingested 7.5 g/kg of thermoneutral sports drink （CON）, sugar-free syrup-flavored ice slurry （WS） or sports drink ice slurry （SS） in 30 min. Then, they exercised at 65% of the maximal oxygen uptake until volitional fatigue in a warm environment. Exercise duration, rectal temperature, forehead skin temperature, average skin temperature, heart rate, blood sample, body weight, urine specific gravity, rating of perceived exertion, and thermal sensation were measured. Mean changes in rectal temperature and forehead skin temperature was significantly increased, and the thermal sensation before the exercise was significantly decreased. However, no difference was observed in the duration of exercise, blood sodium concentration, and blood glucose level. It is considered that the exercise duration was shorter than expected because the exercise intensity we used was too high for participant in this study, and no improvement in exercise capacity or difference due to composition was observed by ingestion of ice slurry. In the future, it will be possible to clarify the effects of differences in composition by reexamining using exercise conditions that improve athletic performance with ice slurry.
