<p>&nbsp;&nbsp;&nbsp;&nbsp;The purpose of this study was to investigate technical factors in floater shot, which is a new and an advanced basketball skill, by comparison between an expert (n＝1) and a novice (n＝1) in Japanese basketball player. Each subject had executed floater shots against a defense until 10 successful floater shots were completed. Nine trials of running jump on left foot, the most emerging pattern from the subjects, were assessed by a three-dimensional motion analysis system. By comparison between the expert and the novice player, the expert player demonstrated 1) significantly longer time catching the ball to jumping, 2) significantly shorter travel distance of center of gravity in a phase between taking off the ground and landing 3) a posture that expert playersʼ shoulder was consistently parallel on the hip in the horizontal plane, and 4) higher reproducibility in the upper body kinematics during a phase between taking off the ground and releasing the ball.</p>
