Abstract

In 1995. FIVE implemented ten amendments to the international volleyball rules. The most controvenial amendment was allowing athletes to use their feet in official games. The purpose of this pilot study was to investigate differences in using a kicking method and a traditional roll method in retrieving balls, which were flying away from the court. backward toward the court. The results revealed that there were significant differences in vertical and horizontal displacement of the CG and in execution time. Shorter execution duration and less displacement of the CG in the kicking method might make this more efficient than the traditional skill. Although the average horizontal velocity in the execution phase seems to be similar in both skills, the player using a kicking method might be faster in reaching the ball since he may have more time in the approach phase.
