Exercise Box Jump to Increase the Strength of Long Passes and Shots

摘要

The purpose of this research was to evaluate the training with the box jump method in improving the soaring kick for high school students in Indonesia, especially in the East Kalimantan province. This research was an experimental study of one group with a pretest-posttest design. The research population took one of 40 high school students using the random sampling of the total population. Data analysis technique used statistical tests. The result of preliminary data analysis on pretest obtained total score of 54, whereas after being treated by the box jump method, the posttest obtained total score of 91. The research took 40 samples who were given the box jump training which obtained F_(count) = 8.791 and by using dk = 39 and α = 0.05 so obtained F_(table)=1.685. Hence, F_(count) > F_(table). These results indicate an increase in the soaring kick by samples that have been tested. Based on the results of the calculations, it can be concluded that there is a significant 37%increase after treatment with the box jump training method.
