휴대폰을 활용한 동영상 피드백이 배드민턴 하이클리어 기술 학습에 미치는 영향

초록

Purpose: The purpose of this study is to investigate whether video feedback using mobile phones affects the learning (accuracy, consistency) of badminton high clearance technology, which is one of the open exercise techniques, and to verify the continuity of learning effect on it. additionally, this study is to present the possibility of the use of mobile video feedback in the exercise learning field and to provide basic basis. Methods: Participants were 26 women who were assigned to mobile video group (8), demonstration feedback group (9), and non - feedback group (9). The acquisition phase for badminton high clear technology was 3(group) × 5(Block of trial), and the retention phase was 3(group) × 2(Block of trial) factorial design with repeated-measures on last factor. The mean radial error (MRE) and bivariate variable error (BVE) were used as dependent variables. Results: First, mean radius error and bivariate variable error in the acquisition phase the error score decreased significantly according to the block of trial. There was also a significant difference in the main effect according to the group and post-hoc results showed that the mobile video feedback group and the demonstration feedback group were compared with non - feedback group the error scores were significantly lower. Second, The mean radial error was significantly decreased by block of trial at the retention phase of post - hoc, the difference between the mobile video feedback group and the non - feedback group appeared significant difference. There was no statistically significant difference in the main effects of bivariate variable error. However, of post-hoc according to group, mobile video feedback group and demonstration feedback group appeared lower error score than non - feedback group. Conclusion: it is suggested that mobile video feedback is more efficient than the conventional traditional method, and it suggest that mobile video feedback can be used as a tool to promote learning in the field of motor learning.
