The Difference in Perceptual Anticipation Between Professional Tennis Athletes and Second-Grade Athletes Before...

To investigate the differences in cognitive processing of perceptual anticipation of tennis players at different levels before batting by the event-related potential (ERP) technique, we used the skilled-expert paradigm. We compared the cognitive and neural mechanisms of professional tennis athletes and second-grade athletes relating to their perceptual anticipation of the batting line at different time points [the time point of the ball landing (T0), and the 80 ms before batting time point (T1)]. The results showed that, regardless of the T0 or T1 time point, professional tennis athletes had shorter anticipation times and higher correct batting line rates than second-grade athletes. The ERP results demonstrated that compared with second-grade athletes, professional tennis athletes induced smaller N1 amplitudes and larger P2 amplitudes in early perceptual anticipation, and induced smaller N2 and larger P3 amplitudes in late perceptual anticipation. These studies suggest that, regardless of whether they are in an early or late stage, tennis professional athletes are faster and more accurate in respect of their perceptual anticipation of tennis lines than second-grade athletes are. This is possible since the relevant neural network of the former is more easily activated and faster. The prefrontal cortex may be a critical area of the brain for perceptual anticipation in tennis.
