Abstract:
Long jump is a jump to achieve results as far as possible. This study aims to find out the truth about the factors of physical ability that include leg muscle power, abdominal muscle power, flexibility of strike, back flexibility, speed, and coordination of Eye and Foot in predicting the achievement of long jump style hanging on junior high school students. This research used a quantitative approach with correlational research method. The population of this research is the students of SMP Negeri 2 Bulukerto, the sample is 100 students. The variables of this study consisted of independent variables, namely physical abilities that include leg muscle power, abdominal muscle power, strike flexibility, back flexibility, speed and coordination of eye and foot. The dependent variable is hang style long jump achievement. Data analysis technique used regression correlation analysis by testing the normality and linearity test prerequisite. Hypothesis testing using regression analysis and correlation of each predictor and multiple regression analysis and multiple correlation. The results showed that when the physical ability factor simultaneously predicted the achievement of long jump style hanging, there would be an increase in the long jump performance of hanging force of 1.0925 for each increase of 1 unit of leg muscle power measurement, an increase of 0.0582 for each increase of 1 unit of measurement Stomach power, an increase of 0.306 for each increase of 1 unit of flexibility measurement of strike, an increase of 0.627 for each increase of 1 unit of measurement of back flexibility, an increase of 0.269 for each increase of 1 unit of velocity measurement, and an increase of 0.0184 for each increase of 1 unit of measurement of coordination of eye and foot. The conclusion of this study is that the ability factor has a correlation and can predict the achievement of long jump hanging style.
