Outline of Final Research Achievements

High intensity resistance exercise decreases the cerebral blood flow (CBF). We examined whether the decrease in CBF compromises the performance of a cognitive task through cerebral oxygenation after a high intensity resistance exercise.
The CBF decreased after resistance exercise. Cerebral oxygenation did not change from the rest after exercise nor recovery period. Cognitive performance did not decreased after exercise and recovery period compared to the rest. Theses findings suggest that cerebral oxygenation is maintained and cognitive function is not compromised during a cognitive task despite the decrease in CBF after a high intensity resistance exercise.

Academic Significance and Societal Importance of the Research Achievements

多くの人々が健康維持・増進を目的にレジスタンス運動に取り組んでいる．レジスタンス運動は脳血流の低下を引き起こすが，果たして脳循環へ悪影響を及ぼすのみなのか？運動の効果を正しく理解するためにも，本研究では，レジスタンス運動が認知課題に対する血流の応答性や脳酸素動態に及ぼす影響を明らかにすることを目的とした．
