Acute exercise has been shown to improve executive function, and in particular performance on tasks that measure inhibitory control. However, few studies have compared laboratory-based exercise sessions to more complex modes of exercise, such as soccer, that involve attention to multiple aspects of the environment and for which performance success depends on the active engagement of executive control processes.

PURPOSE: To compare the effects of acute treadmill exercise versus futsal (indoor soccer) on performance and electroencephalographic event-related potentials measured during an inhibitory control task.

METHODS: Twelve experienced soccer players (24.8±2 years) completed three counterbalanced 20-minute sessions of: 1) seated rest; 2) moderate intensity treadmill exercise; and 3) a game of futsal. Once heart rate (HR) returned to within 10% of pre-activity levels, participants completed the Stroop Color Word Conflict Task while reaction time (RT) and P300 event-related potentials were measured.

RESULTS: HR did not significantly differ during treadmill exercise (122.4±5.4 bpm) compared to futsal (126.7±6.7 bpm). Reaction time during Stroop performance was significantly faster following the futsal game (765±29 ms) compared to seated rest (835±28 ms), but was not significantly different than treadmill exercise (784±22 ms). However, the P300 amplitude at three midline recording sites was significantly greater following futsal (Fz=5.77±2.87; Cz=4.84±1.66; Pz=4.25±1.43 μv) compared to both the treadmill exercise (Fz=4.96±2.66; Cz=4.02±2.58; Pz=3.7±1.02 μv) and seated-rest conditions (Fz=4.19±1.58, Cz=3.12±1.69, Pz=3.09±1.42 μv).

CONCLUSIONS: These findings suggest that single bouts of indoor soccer among college-aged soccer players, compared to treadmill and seated-rest conditions, may engender the greatest effect on brain networks controlling attention allocation and classification speed during the performance of an inhibitory control task. Future research is needed to determine if cognitively engaging forms of sport-related aerobic exercise may differentially impact executive control processes in less experienced and older adult participants.
