This study investigated effects of the immediate feedback training on the improvement in the skeleton starting motion using a motion model for coaching. The motion model for coaching the skeleton starting motion was created from the motion data of eleven excellent male athletes who participated in the Intercontinental and Europe Cups in 2018. In the immediate feedback training of an hour with the push skeleton, in which six participants attempted, a video delayed playback system was used to compare the participants' starting motion with the motion model. The starting motions of the pre- and post-immediate feedback training were recorded with two video cameras, and participants' motive consciousness and motion image of the starting motion were collected with a questionnaire method.
The step length of the 1st step (p＝0.046) was significantly increased after the immediate feedback training. The motion deviation as an index of the change in the starting motion decreased in the hip and shoulder joints, but that of the left ankle joint increased. The motive consciousness and motion image of critical points differed among the athletes and a coach, but were able to be shared and exchanged among them during the immediate feedback training with the help of the motion model. These results indicated that the immediate feedback training using the motion model was effective in improving the skeleton starting motions, as well as the motive consciousness on the critical points.
