The results of data analysis showed that there was a significant effect of the up and down stairs training method on the ability to jump frogs in students who took part in extracurricular sports in athletics. The results of the t-test obtained the value of sig. (2 tailed) of 0.01 < 0.05 then Ha: accepted and Ho: rejected. Based on the results of this study, it can be interpreted that the method of going up and down stairs has an influence on the frog's jumping ability.
