Effects of Visuo-motor Behavior Rehearsal, Relaxation, and Imagery on Karate Performance

Abstract

The present investigation attempted to determine whether imagery combined with relaxation (VMBR) is more effective in facilitating karate performance than either imagery or relaxation alone. Each subject ( N = 32) was randomly assigned to either a VMBR, relaxation, imagery, or attention-placebo control condition in a one-way design. During the first day of the karate class (which met twice a week), each group was individually provided with an explanation of how to practice their assigned strategy at home. Trait anxiety tests were administered at the beginning and the end of the 6-week test period. In addition, performance tests were administered at the end of the testing period along with precompetitive state anxiety. Trait anxiety results indicated that all subjects displayed a reduction in trait anxiety over the course of the testing period. State anxiety results indicated that the VMBR and relaxation groups exhibited lower levels of state anxiety than the imagery and attention-control groups. Performance was broken down into three subareas which consisted of skill, combinations, and sparring (actual competition). Results only showed an effect for sparring, with VMBR group exhibiting better performance than all other groups.
