 By employing the Autonomous Posture Conversion Teaching (APCT) method, we attempted to improve the technique of immature swimmers in pushing off from the wall and gliding for a long distance. For this we conducted interventional experiments whereby the gliding distance during practice was continuously monitored, along with changes in subjective evaluation by the learner and observations of motion made by a third party. The study subjects were 14 college students (10 male, 4 female) majoring in sports science, all of whom submitted written consent to participate. The subjects participated in 13 practice sessions focusing on pushing off and gliding from the pool wall using the APCT method. We conducted measurements at the beginning of the first practice, and at the end of the 5th, 10th and 13th practices. The results were compared between the practices and assessed from multidimensional aspects, including gliding distance, velocity, subjective experience by the participants, and observations made by third parties.
 It was found that the gliding distance and velocity increased progressively at each measurement point. One-way ANOVA revealed significant changes in the main effects after the intervention, including gliding distance and velocity, compared with those before the intervention. The subjective values and observation values also increased progressively with each measurement.
 In conclusion, when using the APCT method, it is preferable to conduct at least five practice sessions. It is important for immature swimmers to increase their wall contact time, and to ensure they use a stronger countermovement for pushing the wall.
