Research has indicated that the use of imagery may aid in recovery from injuries and reduce the perception of pain in athletes during and after competitions. There is little research concerning acute pain and soreness, such as delayed-onset muscle soreness (DOMS). PURPOSE: To determine whether the use of guided imagery for healing will affect soreness, pressure pain threshold (PPT), and performance associated with DOMS. It was hypothesized that those who listen to a healing imagery script would report less soreness, higher pain threshold, and better performance following DOMS than a control group. METHODS: Participants (38) completed two days of testing with 48 hours between them. At the end of the first day, DOMS was induced by performing 6 sets of 15 reps of isokinetic eccentric exercise at -1.05 rad/sec. Each day consisted of tests of soreness, PPT, vertical jump, isokinetics at 6 speeds, and a Wingate test. 20 participants listened to a healing imagery script 10 times within the 48 hours after inducement of DOMS while 18 listened to relaxing music. RESULTS: Perception of muscle soreness was worse for the front and back of the leg (p<.01) regardless of group and the control group reported greater pain perception both before and after the intervention than the imagery group (p<.05). PPT was lower after treatment in the lateral hamstring regardless of group (p<.05). Peak torque for knee extension at 1.05 rad/sec was reduced after treatment for both groups (p<.01). Peak torque for knee flexion at 2.09, 3.14, 5.24, & 6.28 rad/sec was better after treatment for both groups (p<.05) and peak torque for flexion was better at 6.28 rad/sec (p<.05) for both groups. While the Power Drop percentage on the Wingate test appeared better for the imagery group and worse for the control group following treatment, this failed to reach statistical significance (p=.07). CONCLUSION: Healing imagery had no significant impact on perception of soreness, PPT, isokinetic measures, or anaerobic power testing. Based on the actual, but non-significant, changes in power drop results from the Wingate test, it appears that imagery could impact longer duration anaerobic performance as opposed to short duration performance. Further research is needed to determine if healing imagery can improve performance on longer anaerobic and possibly aerobic activities.
