중학교 엘리트 야구선수들의 포지션별 눈-손 협응력과 반응시간 비교

Abstract

The purpose of this study was to compare and analyze the eye-hands coordination and reaction time (light-response, sound-response) from different positions (infielder, out-fielder, pitcher, and catcher) of middle school elite baseball players. The total subjects of this study were 152 of middle school elite baseball players. The players were divided into infielder group (IG, n=58), outfielder group (OG, n=25), pitcher group (PG, n=52), and catcher group (CG, n=17). Visual perception-motor coordination was measured by a T-Wall visual reactor, an eyes-hands coordination measurement tool. The reaction time was assessed by using a response measuring instrument. The results of this study showed that in run-time for eyes-hands coordination was significantly shorter in IG and PG compared to OG, and total penalty scores were lower in IG and PG compared to CG. Systemic reaction time, In light-reaction time, IG were significantly faster than OG and CG, Also, in sound-reaction time, IG was significantly faster than CG. The eye-hands coordination (total score, runtime) showed a significant correlation with reaction time (light-reaction time: r=.330, sound reaction time: r=.418). These results indicate that there are differences of eye-hands coordination and reaction time based on positions from the middle school baseball players. Therefore, a eye-hands coordination training program should be established to improve the performance and to develop potentiality for the youth baseball players.
