Summary

"This study investigates whether the length of time spent on a mentally demanding task affects brain activity and jumping performance in physically active young men. Twelve healthy male university students, all regularly engaged in sport, completed four separate testing sessions on different days, each at least 72 hours apart. In one session (the control condition), participants watched a calm nature documentary. In the other three sessions, mental fatigue was induced by having participants perform a demanding attention task (the Stroop color-word test) continuously for 10, 15, or 30 minutes. Before and after each session, brain activity was recorded using electroencephalography (EEG), a painless method that measures electrical activity through sensors placed on the scalp. Immediately afterward, participants performed a countermovement jump test, a standard measure of explosive leg power used in sports science. The study examines whether longer periods of mental fatigue produce progressively larger changes in brain activity and jump performance, and whether changes in brain activity are related to changes in jumping ability. The findings may help athletes, coaches, and students better understand how mentally tiring activities, such as studying or exams, could affect physical performance shortly afterward."

Conditions

  • Mental Fatigue
  • Athletic Performance
  • Cognitive-Motor Interaction

Interventions

BEHAVIORAL

Nature Documentary (Control)

Viewing of a neutral, cognitively undemanding nature documentary matched in duration to the mental-fatigue protocols, serving as a non-fatiguing control condition.

BEHAVIORAL

10-Minute Stroop Task

Continuous performance of the Stroop color-word interference task for 10 minutes to induce mental fatigue.

BEHAVIORAL

15-Minute Stroop Task

Continuous performance of the Stroop color-word interference task for 15 minutes to induce mental fatigue.

BEHAVIORAL

30-Minute Stroop Task

Continuous performance of the Stroop color-word interference task for 30 minutes to induce mental fatigue.
