Key result
Left temporal EEG neurofeedback training elevated low- and high-alpha EEG power across both temporal regions and enhanced shooting performance compared to physical skill training alone.
Why the study?
To determine the effectiveness of left temporal EEG alpha neurofeedback training during the aiming period on cerebral cortical activation and performance accuracy compared to physical skill training alone in pre-elite air pistol shooters.
Does left temporal EEG neurofeedback training improve shooting performance and alter cerebral cortical activation in pre-elite air pistol shooters?
Does left temporal EEG neurofeedback training improve shooting performance and alter cerebral cortical activation in pre-elite air pistol shooters?
Left temporal EEG neurofeedback training enhances cerebral cortical arousal and improves precision-aiming performance in air pistol shooters.
Neurofeedback may aid shooting accuracy; leaves open benefits over physical training alone in larger trials.
Objectives: The present study employed individualized magnitudes of electroencephalographic (EEG) alpha (8–12 hz) power in the left temporal (T3) region as a neurofeedback target parameter during the aiming period in pre-elite air pistol shooters to determine its effectiveness on cerebral cortical activation and performance accuracy compared to physical skill training, only. Method: Shooting scores and EEG activity in the left and right temporal regions were collected from 20 healthy air pistol shooters (10 assigned to neurofeedback training) before and after a 16-session intervention completed within 6 weeks. Specifically, EEG low-alpha (8–10 hz), high-alpha (10–13 hz) power, and coherence obtained at the T3-Fz and T4-Fz recording sites over three consecutive 1-s intervals prior to trigger pull, were subjected to three separate 2 × 2 × 2 × 3 (Group x Hemisphere x Time x Epoch) ANOVAs. Results: The neurofeedback group exhibited elevated low- and high-alpha EEG power across both temporal regions, but no differences in EEG broad-band alpha coherence, accompanied by enhanced performance after the intervention compared to the control group. Conclusions: The findings support the influence of neurofeedback training on cerebral cortical arousal and performance of a precision-aiming task, however, the influence of the neurofeedback on brain dynamics (i.e. alpha power) extended beyond the targeted region as a nonspecific manifestation of cerebral cortical inhibition leading to neural efficiency at the homologous sites.

Lo et al. (2024) studied Healthy air pistol shooters (n=20). Left temporal (T3) EEG neurofeedback training vs. Physical skill training only was evaluated on Shooting scores and EEG activity (low-alpha, high-alpha power, and coherence). Left temporal EEG neurofeedback training elevated low- and high-alpha EEG power across both temporal regions and enhanced shooting performance compared to physical skill training alone.
