Background: Mental fatigue is a psychobiological state caused by extended periods of cognitive effort, and evidence suggests that mentally fatigued athletes present impaired physical performance. Different ergogenic aids have been proposed to counteract the deleterious effects mental fatigue, but whether brain stimulation can still unknown. This scenario even more obscure considering these interventions (mental induction stimulation) in very experienced population consisting master athletes. Method: Ten swimmers (30 ± 6 years old 14 8 experience) participated study. They underwent four experimental conditions before an 800-m freestyle test: with stimulation; without absence no stimulation. was induced cognitively demanding Stroop Color Test, whereas applied on temporal cortex. After that, swan 800 m as fast possible provided their ratings perceived exertion (RPE) every 200 m. Results: effectively induced, evidenced greater perception errors last blocks task. did not influence performance (time complete swimming trial) RPE. Similarly, failed change two parameters, regardless induction. Conclusion: The prolonged influenced, under conditions, induction, cerebral stimulation, association.
