점프 동작이란 무엇인가? | 점프 동작은 운동선수뿐만 아니라 일반인들도 경험하는 인간의 기본적인 동작이며(Adrian & Cooper, 1989; Lee, Lee & Choi, 2001), 점프 후 착지 동작은 자유낙하에 의한 피할 수 없는 동작이다(Cho, 1999). | |
점프 동작 시 자주 발생하는 부상은 무엇인가? | 하지만 점프 동작 이후 수반된 착지 동작은 운동 부상과 밀접한 관련이 있기 때문에 착지와 부상의 관련성에 대한 연구들도 활발하게 진행되어지고 있다(Cho & Kim, 2011; Ross & Guskiewicz, 2004; Safran, Benedetti, Bartolozzi & Mandelbaum, 1999). 착지 중 부상은 인체가 견딜 수 없는 강한 지면반력에 의한 충격이 전달되어지거나 잘못된 자세로 착지할 경우 비접촉성 부상(non-contact injury)이자주 발생하게 된다(Kirkendall & Garret, 2000; Meuffels & Verhaar, 2008; Olsen, Myblebust, Engebretsen & Bahr, 2004; Safran et al., 1999; Zhang, Bates & Dufek, 2000). | |
점프 동작이 이루어지는 과정은 무엇인가? | 점프 동작은 다중 관절(Multi-joints)의 폭발적인 근수축을 통해 이루어지며(Aragon-Vargas & Gross, 1997), 하지 관절의 신전 동작을 통해 지면을 미는 힘으로 몸을 공중으로 떠오르게 하는 동작으로써(Adrian & Cooper, 1989), 경기 결과의 중요한 요소이므로 점프 높이를 향상시키기 위한 방법들에 대한 연구들이 활발히 진행되어져 왔다(Blattner & Noble, 1979; Genuario & Dolgener, 1980; Kollias, Hatzitaki, Papaiakovou, & Giatsis, 2001; Vanrenterghem, Lees & Clercq, 2008). 하지만 점프 동작 이후 수반된 착지 동작은 운동 부상과 밀접한 관련이 있기 때문에 착지와 부상의 관련성에 대한 연구들도 활발하게 진행되어지고 있다(Cho & Kim, 2011; Ross & Guskiewicz, 2004; Safran, Benedetti, Bartolozzi & Mandelbaum, 1999). |
