Objective: The purpose of this study was to investigate and compare the acute effects of feedback and goal setting on the speed of roundhouse kick in the Thai national taekwondo athletes. Methodology: The samples were 10 Thai national taekwondo athletes aged between 18-25 years, all athletes have aptitude kick with right leg, who were tested in their roundhouse kick at both sides of the body in three different forms, i.e. normal kick, kick with feedback, and kick with goal setting, in order to test their kicking speeds. The speed variables, i.e. maximum speed and average speed, were then statistically analyzed to determine their mean and standard deviation. A two-way analysis of variance (ANOVA) with repeated measures was conducted to analyze the difference between different kicking forms as well as the pair difference was also tested by Least-Significant Difference (LSD) with a statistical significance at the .05 level. Results: The kicking forms influenced the maximum speed and average speed (p < .05). The side of legs used in kicking influenced the maximum speed and average speed (p < .05). There was also a correlation between the kicking forms and the side of legs used in kicking (p < .05). After comparing each pair, there was a statistically significant difference in average speed of kick with their convenient leg between all three kicking forms at the .05 level. There was a statistically significant difference in average speed of kick with their inconvenient leg between normal kick and kick with feedback and between normal kick and kick with goal setting at the .05 level. Conclusions: According to the study, the acute effect of feedback and goal setting on the speed of roundhouse kick in the Thai national taekwondo athletes influenced the average speed of kick with their convenient leg rather than those with their inconvenient leg. The feedback and goal setting could more increase the kicking speed than normal kick because there is a continuous relationship of learning a source of information that determines the way to perform more skills with more flow and fewer errors.
