The purpose of this study is to develop an effective training method for improving judo players' athletic ability with regard to their lower body using the single-leg hopping method and to obtain some basic data on the testing method for determining its effectiveness. The subjects are 93 male collegiate judo players, concerning whom the number of repetitions of singleleg 4-direction hops (hops in four directions: front, back, right and left) was measured. Also examined was the relationship between its results and their body shape, weight class, technical characteristics of their judo, and their other physical strength measurement results. The findings are as follows: 1) There was a significant negative correlation between the measurements of their single-leg 4-direction hops and their weight. 2) There was a significant positive correlation between the measurements of their single-leg 4-direction hops and their IRM weight ratio for squats, indicating a positive relationship between the singleleg 4-direction hops and the leg-muscular power per weight. 3) There was no significant difference in measurements between right hops and left hops. 4) There was no special relation between the measurements and their (so-called) pivoting foot and their specialties in judo skills. 5) Generally speaking, the measurements of the single-leg 4-direction hops showed a tendency that higher-ranked players display higher measurement values.
