ABSTRACT

This study aims to determine: (1) The difference in the effect of live demonstration and video demonstration exercise models on the biomechanics performance of court tennis service, (2) Differences in the performance of tennis service biomechanics between players who have high and low eye-hand coordination, (3) Effect of interaction between exercise model and eye-hand coordination on the performance of tennis service biomechanics. This study used an experimental method with a 2 x 2 factorial design. The population in this study were all 12 players of the male KKO SMPN 1 Surakarta. The sampling technique used is saturated sampling, the size of the sample taken is 12 players. The data analysis technique in this study used ANOVA. Before being tested with ANOVA, first using the prerequisite test of data analysis with sample normality test (Lilliefors test with = 0.05 %) and homogeneity test of variance (Bartlett test with = 0.05 %). Based on the results of the study, it can be concluded as follows: (1) there is a difference in the effect of live demonstration and video demonstration exercise models on the performance of tennis service biomechanics. The effect of the live demonstration exercise model is better than the video demonstration exercise model, (2) there are differences in the biomechanics performance of court tennis service between players who have high and low eye-hand coordination. The biomechanics performance of court tennis services on players who have high eye-hand coordination is better than players who have low eye-hand coordination, (3) there is an interaction between training models and eye-hand coordination on the biomechanics performance of court tennis services. Players who have high eye-hand coordination are more suitable if given a live demonstration exercise model. Players who have low eye-hand coordination are more suitable if given a video demonstration exercise model.
