The effect of slow-motion imagery on performance of a complex motor skill

purpose of this study was to examine the effect of slow-motion imagery on the performance of a complex motor skill using a single subject multiple baseline across individuals design. Five intermediate level long jumpers (male and female, ages15 - 19) participated in long jump training sessions during a 2 - 5 week baseline period and an 8 week slow-motion imagery training period. The dependent measures of jump distance, accuracy of take off, and subjective rating of style and technique from along jump expert, were hypothesized to be enhanced by slow-motion imagery training. Physical self-efficacy and locus of control were also hypothesized to be enhanced by the treatment and were measured pre and post test along with imagery ability. Results indicated three subjects that significantly improved imagery ability also improved imagery enhanced jumping performance over baseline performance. Two subjects did not significantly improve imagery ability and did not improve imagery enhanced jumping performance. Generally, subjects whose jumping performance improved also widened and enhanced physical self-efficacy and internalized locus of control. Therefore, results suggest that slow-motion imagery training will enhance the performance of a complex motor skill provided there is a consistent improvement in imagery ability.
