Abstract

Action observation (AO) training and motor imagery (MI) training have long been used independently as effective training methods to facilitate skill acquisi- tion and learning. Recently, neurophysiological and behavioral studies on AO+MI training have shown that combinations of AO+MI training may be more effective than AO or MI training alone. However, the optimal scheduling of AO+MI train- ing remains to be fully explored. Therefore, the purpose of this study was to exam- ine the effect of different AO+MI training schedules of Taekwondo Poomsae on the changes in the structure formation of mental representations in long-term memory and motor variables over the course of learning. Forty participants with no previous experience in Taekwondo were randomly assigned to one of four groups: simultane- ous training group (AO+MI, AO+MI, …), alternate training group (AO, MI, AO, MI, …), blocked training group (AO, AO, …, MI, MI, …), and no-training group. Participants practiced the Taekwondo Poomsae thirty trials a day for three days of training. Mental representation structure and skill performance were measured be- fore and after three days of training as well as after a retention interval of one day. The results of this study showed that the three different AO+MI training improved mental representation structure and skill performance. In particular, the effect of alternate AO+MI training was relatively stronger. Taken together, the findings of this study suggest that simultaneous, alternate, and blocked AO+MI can be used as effective training schedules for enhancing the learning of a sequential motor skill, among which alternate AO+MI training schedule may be more effective.
