間欠的運動における強度の違いがサッカー選手の認知機能に及ぼす影響

抄録

　The intensity of play is a recent change that symbolizes the modern evolution of soccer. This study investigated whether the intensity of intermittent exercise and cognitive function have an inverted-U relationship. Male members of a Japanese university soccer club participated in the study (N = 13; mean age ± SD = 20.2 yr ±0.94). They performed a pass choice reaction task, a standardized test assessing the speed and accuracy of information processing in soccer, and the Stroop test for assessing attention after exercising at different intensities (Control Test: CT; Moderate Intensity: MI; High Intensity: HI). The results indicated that the reaction times in the MI and HI pass choice reaction task were significantly shorter and that the frequency of correct responses in the Stroop test was significantly higher than in the CT. However, neither test demonstrated significant differences between MI and HI. These results suggest that intermittent exercise might improve information processing and attention function. Nevertheless, the results did not indicate that exercise intensity and cognitive function have an inverted-U relationship.
