EEG signatures such as temporal, central, and occipital alpha, frontal midline theta, and intra- and inter-hemispheric coherence have been related to optimal motor performance in recent years. The sensorimotor rhythm (SMR) is a special frequency band of 12-15 frequency mainly in sensorimotor area. The power of SMR is inversely related to the activation of this area. Research has shown that SMR is related to the automaticity of motor process. Therefore, this study intended to explore the relationship between SMR and shooting performance in skilled air pistol shooters. Eight skilled shooters (aged 22±1.4 yr) with 5.1±2.81 years of shooting experience were recruited to shoot for 40 trials while EEG was collected. SMR for the 10 best shots (9.74±0.44) was contrasted with the 10 worst shots (7.5±0.81). A 2 x 3 (performance x epoch: -3000 to -2001, -2000 to -1001, -1000 to -1) ANOVA showed significant epoch main effect. Post hoc analysis revealed that the third epoch was significantly higher than the second and the first epochs. The results suggest that the skilled shooters reduced the SMR activity during the aiming period leading to the trigger pull. No statistical significance was found for performance related effects. The finding was inconsistent with results from expert-novice comparison study that found lower SMR in expert golfer compared with the novices. Future study may employ an expert-novice comparison approach to examine the relevance of SMR in air pistol shooting performance.
