The aim of this study was to examine the effect of overt and covert motivational
self-talk on perceived exertion and performance in a progressive exercise until
exhaustion in wrestlers. The population consisted of wrestlers in Urmia and 15
volunteer subjects were selected. This study was performed in three sessions with a
one-week interval. The first session was held without self–talk while the second and
third sessions were held covertly and overtly respectively. Bruce aerobic exercise
test was used in this study as well. The time to exhaustion was considered as
performance. Burg scale was used every 3 minutes in order to measure subjects'
exhaustion. To analyze the data, ANOVA with repeated measures and TUKEY post
hoc test was used. The results showed that only covert self-talk had a significant
effect on subjects’ performance (P=0.002). Also, overt motivational self-talk
(P=0.001) significantly decreased the subjects' perceived exertion rather than
covert self–talk. There was no significant difference between covert self-talk and
without self–talk (P=0.121). In conclusion, overt motivational self-talk decreased
the perceived exertion of the subjects in the progressive exercise until exhaustion
while covert motivational self-talk improved subjects’ endurance.
