Introduction: EEG signatures such as temporal, central, and occipital alpha, frontal midline theta, and intra- and inter-hemispheric coherence have been related to superior motor performance in recent years. The sensorimotor rhythm (SMR) is a special frequency band of 12-15 frequency in the 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. Method: Twenty-four skilled shooters (aged 18±2.5 yr) with 3.7±2.6 years of shooting experience were recruited to shoot for 40 shots while EEG was collected. Results SMR for the 10 best shots (9.77±0.22) was contrasted with the 10 worst shots (7.61±0.61). The 2 x 3 (performance x epoch: -3000 to -2000, -2000 to -1000, -1000 to 0) ANOVA showed significant a interaction effect and epoch main effect. Simple main effect analysis revealed that the SMR of the third epoch for good performance was significantly higher than that of the poor. Discussion: The results suggest that when the skilled shooters reduced the sensory motor activity during the aiming period, they performed better. This finding may shed light on the understanding of fine mental regulation during the short period of aiming processes.
