The Effect Of Imagery Training On The Accuracy Of Free Throws In Basketball Players In Terms Of Concentration

This study aims to determine: (1) the difference in the influence between internal imagery and external imagery exercises on the accuracy of free throws; (2) the difference in the influence of players who have high and low concentrations on the accuracy of free throws; and (3) the interaction between internal imagery and external imagery exercises and the concentration on the accuracy of free throws in basketball players. This type of research is an experiment using a 2 x 2 factorial design. The population in this study was 38 basketball SME players from Universitas Islam Indonesia. The sample in this study was 20 people who were taken using purposive sampling techniques, then ordinal pairing was carried out to divide each group. The instrument used is to measure concentration, namely the Grid Concentration Test, while the accuracy of free throw uses a free throw test. The data analysis technique used is a two-way ANOVA. The results showed that: (1) There was a significant difference in influence between internal imagery and external imagery exercises on the accuracy of free throws in basketball players, with an F value of 51.984 and a significance value of p 0.000 < 0.05. The internal imagery exercise group was higher (good) compared to the external imagery exercise group with a posttest average difference of 4.00. (2) There is a significant difference in influence between players who have high and low concentrations on the accuracy of a basketball player's free throw, proven by an F value of 38.416 and a p-significance value of 0.000 < 0.05. Players who have a high concentration are higher (good) compared to players who have a low concentration, with a posttest average difference of 4.00. (3) There is a significant interaction between imagery exercises (internal imagery and external imagery) and concentration (high and low) on the accuracy of a basketball player's free throw, with an F value of 4.264 and a significance value of p 0.047 < 0.05. There is a significant difference in the influence between internal imagery training methods and external imagery training methods on the accuracy of free throws in basketball players. The internal imagery training method is better than the external imagery exercise on the accuracy of free throws on basketball players. There is a significant difference in the effect of high concentration and low concentration on the accuracy of free throws in basketball players. Players who have high concentration are better than t
