Cognitive constrain of individual constrains which can be created with imagery and is a factor in many tasks affecting the performance has been investigated. Thus, the aim of the present study was to investigate the effect of PETTLEP imagery on the accuracy and speed basketball pass skill. 44 female students of Faculty of Physical Education, University of Tehran (mean age of 22.45±2.3 years) were selected by convenience sampling method and participated in this study. In pretest, participants performed 2 blocks of 10 trials of accuracy and speed basketball pass. Then, they were assigned to one of the four groups homogeneously: accuracy pass PETTLEP imagery, speed pass PETTLEP imagery, accuracy control, and speed control. Two groups of imagery listened to the imagery audio during 3 days for 8 minutes per day. Then, subjects participated in posttest, retention and transfer tests. For data analysis, mixed ANOVA was used. In case of significance, independent t test was used for intergroup comparisons and analysis of variance with repeated measures was used for within-group comparisons with significance level of α=0.05. The results of analysis of variance indicated no significant differences between imagery and control groups in pretest. However, there were significant differences in posttest, retention and transfer tests between imagery and control groups (P≤0.05). Also, PETTLEP imagery of accuracy and speed pass improved accuracy and speed pass performance from pretest to retention test; however, there was no such process in transfer test (P≥0.05).

In recent years, researchers have become interested in examining the effect of PETTLEP imagery on motor performance and how PETTLEP imagery can improve the performance. The aim of this study was to compare the effect of PETTLEP imagery and balance practice on dynamic balance in the elderly. Participants were 42 male elderly in Arak city. They were divided into 4 groups based on the scores of dynamic balance pretest. In order to measure dynamic balance, Bass and Star Balance tests were used. Homogeneous training groups included PETTLEP imagery, balance practice, mixed practice (balance practice and PETTLEP imagery practice) and control group. All groups except for the control group practiced 3 sessions (each session 45 min.) a week for 6 weeks. MANOVA with repeated measures was used to analyze the data (P≤0.01). Results showed the mixed and balance practice groups significantly improved in Bass and Star dynamic balance (P=0.000, P=0.001, P=0.000, P=0.000). PETTLEP imagery and control groups showed no significant improvement in Bass and Star dynamic balance (P=0.24, P=0.53, P=0.36, P=0.28). Also, the mixed group had more improvement in Bass and Star dynamic balance than balance practice group (P=0.002, P=0.004). Overall, these results showed that PETTLEP imagery practice along with physical training improved dynamic balance in male elderly, but PETTLEP imagery alone did not affect the improvement of dynamic balance in the male elderly.

The concept of imagery is to make an image of successful movement skill or a
relaxing image in mind with no body training and external experience. The aim of
the present study was to compare the effect of traditional and PETTLEP mental
imagery methods on static and dynamic balance. The statistical population
consisted of all female University of Tehran students who had general physical
education course (1) in the first educational semester in 1389-1390. 54
participants (Mean age 21.94±1.89 yrs) attended voluntary in this study. First, they
completed the Revised Movement Imagery Questionnaire (MIQ-R: Hall & Martin,
1997). Afterwards, pretest of static balance (Stork Balance Test) and dynamic
balance (Modified Bass Test of Dynamic Balance) were performed. Participants
were randomly assigned to three (n=18) groups (Physical training, Traditional
imagery and PETTLEP imagery) and trained for 12 weeks (20 min/week). Finally,
posttests of static and dynamic balance were performed under the same condition
as the pretest. Retention test was performed 24 hours later and transfer test 30
minutes after the retention test. One-way ANOVA test showed no significant
difference in static balance, dynamic balance and imagery ability scores in pretest
among groups (p>0.05). Although ANOVA with repeated measures illustrated that
although all three groups improved significantly in static and dynamic balance
(P0.05).
Overall, results showed PETTLEP imagery was an effective method but not
sufficiently efficient in dynamic balance.
