다국어 초록 (Multilingual Abstract)

The purpose of this study was to classify K5 soccer players into three groups (high-repetition group, load-assisted low-repetition group, and low-repetition group) and to compare the effects of 8 weeks of high-repetition bodyweight Copenhagen Adduction Exercise (CAE), load-assisted low-repetition CAE, and bodyweight low-repetition CAE on eccentric and concentric strength, strength ratio, range of motion (ROM), 10 m and 15 m sprint performance, kick power, change of direction ability (505 test, DD, CODD), and delayed onset muscle soreness (DOMS). This study aimed to provide an effective training program for preventing hip adductor injuries and enhancing functional performance in lower-league soccer players. A total of 36 amateur soccer players in their 20s were randomly assigned to three groups: High Repetition (n = 12), Low Repetition (n = 12), and Load (n = 12). Each group completed an 8-week training program, and pre- and post-intervention measures were obtained for strength (eccentric hip adduction and abduction), DOMS, hip abduction ROM, speed (10 m and 15 m sprint), change of direction ability (505 test, change of direction deficit, deceleration deficit), and maximal shooting power. The results are as follows: 1. As a result of the training program, eccentric hip adduction stren gth showed a significant interaction effect on both sides. In the dom inant limb, all three groups demonstrated significant improvements, with significant post-intervention differences. In the non-dominant li mb, the high-repetition and load groups showed significant increase s, and significant between-group differences were observed after th e intervention. 2. As a result of the training program, eccentric hip abduction stren gth did not show a significant interaction effect. In the dominant lim b, the high-repetition and load groups demonstrated significant impr ovements, while in the non-dominant limb, only the load group show ed a significant increase. 3. As a result of the training program, the eccentric hip adduction-t o-abduction strength ratio showed a significant interaction effect in the dominant limb. The high-repetition and load groups demonstrate d significant improvements, while in the non-dominant limb, only the load group showed a significant increase. 4. As a result of the training program, delayed onset muscle sorene ss (DOMS) showed a significant interaction effect. The load group d emonstrated significant within-group differences, and over the 8-we ek period, DOMS levels were significantly higher in the load group compared to the high- and low-repetition groups. 5. As a result of the training program, hip abduction range of motio n (ROM) showed significant interaction effects and within-group diff erences on both sides. In the dominant limb, significant post-interve ntion differences were observed. 6. As a result of the training program, no statistically significant diff erences were found in inside kick power. 7. As a result of the training program, no statistically significant diff erences were observed in the 505 test. 8. As a result of the training program, no statistically significant diff erences were found in change of direction deficit (CODD). 9. As a result of the training program, deceleration deficit showed n o significant interaction effect in either limb; however, both limbs d emonstrated significant pre–post improvements. 10. As a result of the training program, speed performance showed no interaction effect in the 10 m sprint, although the high-repetition group demonstrated significant pre–post improvements. In the 15 m sprint, a significant interaction effect was observed, with the low-repetition group showing a significant decrease. Based on the above results, 8 weeks of high-repetition bodyweight CAE and load-combined CAE were found to have positive effects o n strength, strength ratio, ROM, and deceleration ability, suggesting that both training methods are effective. In particular, the load-com bined CAE demonstrated strength improvements comparable to the h igh-repetition CAE despite requiring fewer repetitions, indicating gre ater time efficiency. These findings suggest that both training appro aches may serve as effective programs for preventing hip adductor injuries and enhancing functional performance in lower-league socce r players.
