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

The aim of this research was to examine the effects of PETTLEP-based imagery compared to more traditional imagery on learning badminton short service (backhand). For this purpose, 45 male students (age 12-14 years) were non-randomly selected and divided into three groups of 15 students each (they were beginners). The groups exercised in the following way: first group performed PETTLEP-based imagery and practical training. Participants in the PETTLEP imagery group applied the physical principles of PETTLEP imagery training. They were requested to imagine performing badminton short service wearing their complete badminton competition uniform; second group performed traditional techniques of imagery and practical training. Participants in the traditional imagery group engaged in a relaxation session before imagery; third group performed practical training. In 7th, 14th, 21st and 28th session, all subjects performed French test. The obtained data were analyzed by ANOVA and Tokey tests. The results showed a significant difference between PETTLEP-based imagery and traditional technique of imagery groups in learning badminton short service technique. There was a significant difference between traditional technique of imagery group and control group in learning badminton short service technique. In retention test, there was a significant difference between PETTLEP-based imagery with traditional technique of imagery and control group in learning badminton short service technique. It is suggested that coaches and physical educators use PETTLEP when possible.
