The subjects of this study were 15 woman soccer players and 15 untrained woman students at H-Cheju University. Each subject was measured on the muscle strength and peak torque of knee extensors and knee flexors with isokinetic load(60˚/sec, 180˚/sec).
The results were as follows:
1. There was no significant difference between right and left leg strength measured isokinetically in each group.
2. The peak torque of knee extensors and flexors was significantly higher in scoccer players than untrainded students (p<0.001).
3. For the angle of knee joint showing the highest peak torque, there was significant difference between soccer players and untrained students in knee extensors(p<0.05) and right flexors(p<0.01).
4. For knee H/Q ratio, there was significant difference between two groups(p<0.05).
5. For the total work and average power at 180˚/sec, there was significant difference between two groups in knee extensors(p<0.001) and flexors(p<0.01).
6. In soccer players at 60˚/sec, there were significant correlations between peak torque and height and between peak torque and weight.(p<0.001).
7. For the muscular contraction velocity at 60˚/sec, there was significant difference between two groups in flexors (p<0.01).
8. For the muscular indurance at 180˚/sec in extensors and flexors, there was no significant difference between two groups(p>0.05).
In conclusion, there were significantly higher in peak torque, contraction velocity, knee joint´s angle with the highest peak torque, H/Q ratio, total work and average power in woman scoccer player than general students. But there was no significant difference in muscular endurance. Soccer performance is based on the various components including muscular endurance that is one of the most important components. So it is necessary that the training method to improve the various components (especially including muscular endurance) should be done.
