Effect of Imagery Practice Program on Imagery Ability in Thailand Adolescent Cyclists

The purpose of the study was to examine the imagery program in Thai Sport School Cyclist-Students. The experiment was designed in duration of 10 weeks at Lampang Sport School, Thailand. Samples consisted of 66 cyclist-students through random purposive sampling, of male (46) and female (20). They were separated into two groups of experiment (33) and control (33). The questionnaire MIQ-R (Moment Imagery Questionnaire) consists of 8 items of kinesthetic (KI) and visual (VI) to evaluate the imagery ability. Program imagery was adapted from Hogg (2002), Hall (2008). Before starting the study, researcher administered a test to see the reliability of the questionnaire: Reliability for imagery ability=.57. The finding showed that the experiment group consisted of male, (Mean=15.5622, SD=15.5530), female (Mean=15.1000, SD=1.10050). Control Group male (Mean=15.4783, SD=1.64785), female (15.3000, SD=1.15900). There was an increase in visual imagery (VI) scores across the three different periods where Multivariate results indicated statistically significant F (2, 63) =4.212, p-value=.019 (p<.05), eta square=.118 (11.8% large effect) at pre-test, post-test 1 and post-test 2 (Experiment and Control group). Kinesthetic imagery (KI) scores increased across the three different periods where Multivariate results indicated statistically significant F (2, 63) =.879, p-value=.017 (p<.05), eta square=.121 (12.1% large effect) at pre-test, post-test 1 and post-test 2 (Experiment and Control group). This research suggested that the imagery program does improve mental skills of Thailand adolescent cyclists in visual and kinesthetic imagery ability.
