플라이오메트릭과 코어 운동이 지적장애 남자축구선수의 체력, 경기기술 및 기능성 움직임에 미치는 영향

Abstract

This study conducted plyometric and core exercises with soccer players with intellectual disabilities for 12 weeks to examine the effects on physical fitness, game skills, and functional movement. The following conclusions were drawn.

First, in the change of physical fitness before and after plyometric and core exercises, the exercise group showed a significant difference in the peak torque of right thigh extensor(p<.001), the peak torque of left thigh extensor(p<.001), the peak torque of right thigh flexor(p<.001), the peak torque of left thigh flexor(p<.001), the peak power of right thigh extensor(p<.01), the peak power of left thigh extensor(p<.001), the peak power of right thigh flexor(p<.01), the peak power of left thigh flexor(p<.001), flexibility(p<.001), and dynamic balance(p<.001). Second, in the change of game skills before and after plyometric and core exercises, the exercise group did not show a significant difference in kick and pass but showed a significant difference in shot(p<.001). Third, in the change of functional movement before and after plyometric and core exercises, the exercise group showed a significant difference in FMS(p<.001).

This study found that plyometric and core exercises had a positive effect on physical fitness, game skills, and functional movement. Soccer players with intellectual disabilities need the strong muscle strength of the lower limbs due to the nature of soccer. Their improvement of the isokinetic muscular strength of legs may prevent injuries, maximize the potentiality of muscle and tendon units, and put out their strength in a moment during the game. It may greatly improve their game performance. The significant improvement of the FMS score suggests that the exercise was effective to reduce injury risk in soccer players with intellectual disabilities. However, there was no significant difference in kick and pass in the items of measuring game skills. It indicates that the excise program structure of this study focuses on the improvement of physical fitness and the exercise should be modified and added to improve game skills. Based on the results of this study, further study should increase the sample size of the subjects to generalize the results of plyometric and core exercises and segment a period to test the short-term effect of exercise. Continuous research is necessary to further examine the exercise effects of various exercise items and characteristics.
