초록
본 연구의 목적은 마우스가드의 착용이 기초 체력 및 운동 능력에 미치는 영향을 밝히는데 있다. 특히 부분피개 마우스가드 착용의 효과를 파악하여 교합의 안정성이 기초 체력 및 운동 능력에 미치는 영향을 밝히고자 한다. 이를 위해 K대학교 체육교육과에 재학 중인 대학생 20명을 대상으로 5가지 교합상태-마우스가드 미착용, 전악피개 마우스가드 착용, 좌우측 편측 마우스가드 착용, 전치부 마우스가드 착용-에서 각각 사이드스텝, 제자리 높이뛰기, 배근력, 악력, 외발서기, 유연성과 같은 기초 체력 및 운동능력을 측정하였다. 본 연구의 결과 전악피개 마우스가드의 착용은 운동능력 측정 항목 중 사이드스텝, 제자리 높이뛰기, 배근력, 악력, 외발서기, 유연성, 전신반응 모두에서 마우스 가드 미착용 시와 비교하여 유의성 있는 차이가 나타나지 않았다. 하지만 부분피개 마우스가드의 착용 시에는 미착용 시에 비해 전신반응이 유의성 있게 향상되었다. 이러한 결과를 통해 전악피개 마우스가드의 착용이 운동능력에 유의한 영향은 없으나 부분피개 마우스가드의 착용은 민첩성 향상에 기여할 수 있는 것으로 사료된다. 뿐만 아니라 교합적인 안정성이 단기적으로는 전신반응의 향상에 긍정적인 효과를 발생시키지 못하는 것으로 판단된다.
Abstract
This study examined the effects of the occlusal stability and a partial coverage mouthguard on physical fitness and motor capacity to determine the importance of the occlusal stability as a possible action mechanism of mouthguards on physical performance. Twenty physical education students were included for measurements of their handgrip strength, back strength, whole body reaction time, flexibility, sidestep test, stork stand test and jumping test according to the following 5 different occlusal conditions: mouth closed position without a mouthguard, with a full coverage mouthguard, with a right partial coverage mouthguard, with a left partial coverage mouthguard and with anterior partial mouthguard. The results revealed no significant difference in any of the measured physical factors between the occlusal conditions with and without a full-coverage mouthguard. On the other hand, a significant difference was observed in whole body reaction between the occlusal conditions with and without the partial coverage mouthguards. Therefore, isokinetic muscle tests on both knee joints and the Wingate anaerobic power test should be performed under the following five occlusal conditions: with or without full-coverage maxillary custom-made mouthguard, with a unilateral right or left partial-coverage maxillary mouthguard and with an anterior partial-coverage maxillary mouthguard. These results suggest that the partial coverage mouthguard had a short-term beneficial effect on agility rather than full coverage mouthguard.
