Previous findings have shown cognitive enhancement and improved motor learning following tDCS. Consequently, there has been growing interest in direct brain stimulation for enhancing sporting skills. We aimed to assess the effect of tDCS on golf putting performance and control of visual attention. Design: Using a mixed factorial design, the effect of stimulation (between-participants) was assessed at baseline, following stimulation and in a pressure test (within-participants). Methods: 73 novice golfers were randomly assigned to transcranial direct current stimulation of frontal, motor or visual cortex, or sham stimulation. Participants first performed a series of golf putts at baseline, then while receiving tDCS and finally under pressurised conditions. Putting performance (distance from the hole) and control of visual attention (quiet eye duration) was assessed. Results: There was no effect of real tDCS stimulation compared to sham stimulation on either performance or visual attention (quiet eye durations), for any stimulation site. Conclusions: While beneficial effects of tDCS have been found in computerised cognitive tests and simple motor tasks, there is currently little evidence that this will transfer to real-world sporting performance
