The Effect of Declarative and Interrogative Self-Talk on Perceived Exertion, Motivation and Anaerobic Power

The current study aims to investigate and compare the effects of declarative and interrogative self-talk on perceived exertion, motivation and anaerobic power performance. In order to carry this study out, 15 female students participated in a within-subject design including control, declarative self-talk and interrogative self-talk phases. So as to measure anaerobic power, participants performed vertical jump in all three phases and after each phase, they completed the self-talk manipulation check, the perceived exertion, and the motivation form. Through applying one-way repeated measures ANOVA, the superiority of anaerobic power performance and motivation in declarative and interrogative self-talk phases compared to the control phase was revealed. In general, these findings support the advantage of declarative and interrogative self-talk in sport performance which is consistent with the theoretical foundations of self-talk about the usefulness of self-talk on motor performance and motivation
