BALL DISTRIBUTION USING THE INSTEP KICK IN COLLEGIATE SOCCER PLAYERS

Abstract

The present study investigates the characteristics of the distribution of the soccer ball during the instep kick to clarify the reproducibility of the ball distribution. Six male collegiate soccer players kicked a soccer ball towards a goal 11 m away (5 sets of 10 trials). Ball distribution was then analyzed using a high-speed camera. In relation to ball velocity, no differences were seen between sets in the distribution distance from the center of the goal (in either the x-axis or the y-axis direction) among all subjects. High reproducibility was observed for all items. Furthermore, no differences were observed between sets in the slopes and intercepts of the regression equations for the ball distribution. These values also showed high reproducibility. An elliptical shape from the lower left to the upper right was revealed after analysis of ball distribution for the instep kick.
