The effect of imagery on performance and level of self-criticism of athletes

Abstract Objectives The aim of this research was to expand knowledge on the use of PETTLEP based guided imagery scripts, as a mental practice, for increasing performance and reduction of self-criticism in athletes. Imagery can serve not only as an accessory, but also as a replacement for part of the training process, as it has the potential to increase the athlete’s performance. Methods The research group consisted of 78 recreational CrossFit athletes who regularly work out and participate in group trainings. The participants were divided into three groups. The physical practice group trained two series of pushups, the imagery group, in accordance with the prescribed script based on the PETTLEP model, visualized these pushups and the role of the control group was to stretch before training. The intervention lasted 4 weeks, with a frequency of three times per week. Results The results showed that imagery is an effective tool for increasing the performance of athletes and in combination of with regular exercise can result in additional performance gains. There have been significant shifts in our study, in some subscales, specifically within groups. In the imagery group, it was namely the subscale of inadequate and reassuring self. In the physical practice group, the shift also occurred in the inadequate self-subscale and the hated self-subscale. However, after comparing these results with the other two groups, there were no significant differences. Conclusions The results confirm the potential of using imagery for increasing performance and reducing self-criticism.
