Determinants of Electrooculography Measurements for Quiet Eye Duration in Archers via Penalty Regularizer

Electrooculography (EOG) is an electrophysiological method used to assess eye movements and the functional status of the retinal pigment epithelium by measuring the potential differences generated during eyeball motion. In recent years, EOG has also been explored as a tool for determining quiet eye (QE) periods in athletes. The QE period refers to the duration an athlete maintains focused visual attention on a target, and it is considered to be closely linked with athletic performance. The application of EOG in this context is emerging as a novel approach to evaluate and enhance athletes’ visual focus and concentration skills. In this study, the relationships between QE period and various free parameters of the athletes were analyzed using penalty approaches (Lasso and Ridge regression). Thanks to this approach, QE periods can be predicted with high accuracy based on the independent variables of individuals without any direct QE measurement for different athletes, and this will contribute to the development of preventive or supportive strategies for performance. The R2 value for the coefficients of the two regression methods was obtained more than 80% and the mean square deviation was less than 5%.
