The purpose of this study was to investigate activation differences in the supplementary motor area of the brain, in response to different types of display modeling (normal vs. stromotion type) and skill level (novice vs. skillful player). A total of 24 male students participated in the study. Twelve were novices who had never played tennis, and twelve were current tennis players at their respective universities. During the observation, electroencephalogram recordings were collected from the supplementary motor area. These data were used to calculate the rate of suppression of the mu rhythm. Calculated variables were analyzed using two-way analysis of variance. Results indicated that novices exhibit significantly higher activation in the supplementary motor area when observing stromotion displays, whereas skillful players exhibit no differences in activation according to the type of display. The results of present study suggest that using stromotion-type action observation may be more effective for beginners.
