Study on distance of horizontal direction movement during the scrimmage volleyball game

Abstract

Study on distance of horizontal direction movement during the scrimmage volleyball game This study was made to investigate the motor activities of the volleyball players during the scrimmage game. The video camera was set just above the center of the volleyball court to capture the activity of the players. Each player wore the white swimming cap during the scrimmage game. The swimming cap was used as marker to digitize the movement of the players. The position data calculated by using 2D-DLT method. The results showed that players moved horizontally 527.58（±141.70）m（mean± SD）during the set. The wing spikers covered 648.61（± 248.92）m, this distance was longer than other position, setters 572.79（±18.23）m, libero players 514.15（± 8.60）m and middle blockers330.15 （± 20.14）m
