Effect of Motor Imagi̇nati̇on Trai̇ni̇ng on Tenni̇s Servi̇ce Hi̇t

Abstract

In this study, it was aimed to reveal the effect of motor imagination training on the hit of the service in the tennis game. 32 male tennis players between the ages of 18-25 participated in the study in the field of tennis in Kayseri. After the first measurements of age, height, body weight and Dewitt-Dugan service and ITN Service test of the athletes, control (n=16) and experimental (n=16) groups were separated by random method. While 8-week technical training was applied to both groups, technical and imagination trainings were applied to the experimental group. At the end of eight weeks, the final test values were taken. The obtained data were analyzed in the IBM-SPSS 25 for Windows package program. In the analysis, the data showed normal distribution. Descriptive statistics were shown with arithmetic mean and standard deviation. As a statistical comparison test, analysis of variance was applied in repeated measurements to see the main effects and the changes in the data with significant interaction over time. In order to reveal the change of the groups over time in the variables whose group time interaction was significant, the Bonfferroni test was applied and the group and time changes were compared. The significance level was taken as p <0.05. In the comparisons between the experimental and control groups; According to the results of analysis of variance in repeated measurements of Dewitt-Dugan service test, no statistically significant difference was found in group main effect, time main effect and group time interaction (p>0.05). According to the results of analysis of variance in repeated measurements in ITN service test measurements, no statistical difference was found in the group main effect (F=0.208, p=0.655, η2=0.015), while the time main effect (F=26.034, p<0.001, η2=0.465) and group time interaction A significant difference was found (F=12.305, p=0.001, η2=0.291). As a result, it can be said that 8-week motor imagination training is effective in more complex motor skills such as the ITN s test, while there is no difference in the tests that do not include complex skills such as Dewitt-Dugan.
