Cognitive exergame training and transcranial random noise stimulation effects on executive control in healthy young adults

Objective: In the present study, we investigated the efficacy of transcranial random noise stimulation (tRNS) combined with an exergame training (physical exercise combined with a videogame) chosen as potential techniques to boost brain functioning and to promote plastic effects in healthy young adults. The aim was to improve the motor response speed and the response time when inhibition was required. Method: Forty-nine participants were randomly assigned to four conditions. The protocol consisted of eight sessions of exergame cognitive training (or no training) associated with the active or sham stimulation of the left dorsolateral prefrontal cortex (left-DLPFC). Results: The results indicated faster simple reaction times following the exergame training, and faster reaction times in Go trials (while the ratio of NoGo trials remained unaltered) following tRNS. No interactions were present between the two procedures. Conclusions: These findings reveal better performance in both tasks with independent effects of the two techniques. Using noninvasive brain stimulation and exergame training may be a viable strategy to increase motor response speed and improve executive control.
