Nontarget Suppression in Ball Sports Multitarget-Tracking Task

Abstract

In order to solve the problem of large interference caused by nontarget tasks on the ball sports field, the author proposes a method for multitarget-tracking tasks. By changing the movement speed of the athletes in the expert group, the novice group, and the control group, we investigate the performance of visual attention tracking and neural oscillatory characteristics in ice hockey players. Experimental results show that the main effect of speed was significant (F = 120.58,$P<0.01$,${\eta }_P^2$ = 0.81), and post hoc comparison results showed that the faster the movement speed, the lower the tracking accuracy. The main effect of speed was significant (F = 31.96,$P<0.01$,${\eta }_P^2$ = 0.53). Post hoc comparison results showed that the faster the movement speed, the lower the ERSP value of the high-frequency alpha rhythm. It proves the influence of speed on the inhibitory effect of nontarget tasks, which is beneficial for athletes to suppress more interference information brought by opponents or the court in the game and plays an important role in improving sports performance and developing the scientific level of sports.
