This study surveyed a total of 90 athletes - 30 Judo players with an career over 3 years, 30 Taekwondo players, and 30 Wrestlers players - measuring their physique and physical strength. On the basis of this survey, we aimed to provided basic sources needed to instruct young students in sports techniques and train excellent ones by comparing which factors of physical strength are superior or inferior according to each game's peculiarity and finding out interrelation between games.
The conclusion this study has reached is as follows:
1. Physique specificity
Judo players show higher physique specificity than wrestlers and taekwondo players in players in body weight, chest girth and thigh girth
2. Physical strength specificity
In terms of physical strength, judo player seem better at back strength, side step test and pull-ups than wrestlers and taekwondo players, while judo and wrestlers players have comparatively better grip strength than taekwondo players. Maenwhile, wrestlers and judo players are better at moblity test than taekwondo players.
3. Correlations between physique and physical strengths
Taekwondo players show close correlations between back strength, grip strength, judo players show grip strength, wrestlers players show that between back strength, grip strength, moblity test, pull-ups and physique.
4. Correlated physical strengths
In taekwondo players, back strength, grip strength, vertical jump, standing long jump, pull-ups are found to be correlated. In judo players, grip strength, vertical jump, 10m shuttle run, moblity test, pull-ups, closed-eyes foot balance are found to be correlated. In wrestlers players, back strength, grip strength, 800m long running, pull-ups are found to be correlated.
