Abstract: Completed in partial fulfilment of the requirements of the degree of Bachelor of Engineering from Nanyang Technological University, this study investigates the correlation of EEG data and sport shooting performance motivated by the possibility of using neurofeedback training to improve shooting performance. This study was undertaken in collaboration with Nanyang Technological University, Fraunhofer IDM and Singapore Sports Association. Sports psychology is a large industry aiming to improve the performance of athletes across many sports. Sport shooting places a large emphasis on psychology for optimal performance and hence this sport was chosen for the study. Traditional sports psychology tools include aptitude and attention tests providing subjective feedback. Biological signal analysis has since been introduced to provide objective analytical data which can be used to observe psychological performance in athletes. Optimal performance in athletes can be achieved by creating the correct balance of psychological and physiological states and hence it is desired to be able to purposely achieve these states before competition. A total of eight shooters, male and female were recorded with results being used from six of them – three rifle shooters and three pistol shooters. Participants were of mixed ability and experience and all completed the experiment using their own equipment which they were familiar with on their own training range in order to ensure they were accustomed to their surroundings. EEG data was recorded using the Emotiv Epoc EEG device to collect emotion and workload based data, scored using machine learning, as well as spectral power. All data was processed using a four second sliding window. A small negative correlation between workload prior to shot release and shooting performance was found in the more experienced shooters while those with less experience demonstrated a slight positive correlation. This indicates that novice shooters require more cognition throughout the shot process. A second finding was the slight positive correlation between alpha power and shooting performance indicating that alpha based neurofeedback training could be used to improve shooting performance.
