Solianik R, et al. - The consequence of prolonged speed–accuracy motor task on the indicators of psychological, cognitive, psychomotor and motor function was investigated by the researchers among young men aged 21.1 ± 1.0 years. FIndings reported the increased working memory function and prefrontal cortex oxygenation at rest and during conflict detection, and the decreased efficiency of incorrect response inhibition and visuomotor tracking after the motor task. In order to sustain the performance of 2-h speed–accuracy task under conditions of self-reported fatigue, task-relevant functions appeared to be maintained or even improved. On the other hand, less critical functions were impaired.
