Outline of Final Research Achievements

We investigated the effect of ice slurry ingestion before exercise on cognitive function. Although no significant difference in cognitive function was observed because the difference in initial values between conditions, the ice slurry condition maintained a slightly higher rate of correct answers with the same reaction time as the control condition. Therefore, it is possible that we could have observed the suppression of cognitive function decline by ingestion of ice slurry if no difference in initial values. In this study, we only examined the effect on cognitive function because of the influence of the corona disaster, and suggested that the ingestion of ice slurry may improve it. Therefore, we will reexam the above, and investigate effective ingestion methods.

Academic Significance and Societal Importance of the Research Achievements

本研究では，より競技現場に即した認知機能を評価する方法を用いて，運動前のアイススラリー摂取が認知機能の低下を抑制する可能性を示唆した。本研究の精度を高め，認知機能の低下を抑制することが立証されれば，これまで結果の不一致や方法論の問題で十分に明らかにされていなかった認知機能に及ぼす影響が明らかになり，アイススラリー摂取によるエルゴジェニック効果のメカニズムを解明する一助となると考えられる．
