Objective To explore the advantages of visual-motor integration in table tennis players, and analyze its neural mechanism based on functional lateralization theory.
Methods 22 table tennis players were selected as a group of experts, and 21 general college students were selected as a group of novices. Using the half-visual field tachistoscopic technique, a visual-motor integration task was set up to test and compare the behavioral differences in visual-motor integration and electroencephalographic characteristics between players and novices.
Results ① The right-hand reaction time of the table tennis experts was significantly shorter than that of the novice group (P<0.05); ② In the visual processing stage, the P1 component latency of the players was significantly longer than that of the novice group, and the N2 latency of their left hemisphere was significantly higher than that of the right hemisphere (P<0.05); ③ In the visual-motor transition and motor execution stages, the players induced greater BA6 negativity wave amplitude and N2 wave amplitude in the BA4 area (P<0.05); ④ In the parietal-occipital region, the players had lower levels of high-frequency alpha rhythmic neural oscillations than the novice grouphad, which was specifically reflected in the low level of high-frequency alpha rhythmic oscillations in the right-handed response mode of the left visual field (P<0.05).
Conclusions ① The visual-motor reaction time of right-handed table tennis players was shorter; ② The right hemisphere of table tennis players can recognize stimuli more quickly in the early visual processing stage and more directly and effectively in the visual motor transition stage; ③ The expertise effect of table tennis players on the visual-motor integration function is mainly reflected in the visual processing of the right hemisphere and the reaction advantage of the left hemisphere.
