초록

본 연구는 복싱 잽 동작 시 제자리 스텝의 사용이 운동역학적 요인들에 미치는 영향을 분석 하는데 목적이 있었다. 이를 위해 최근 1년간 근골격계에 상해가 없었던 오른손잡이 스탠스 유형의 대학교 복싱 선수 8명(나이: 20.38±0.52 yrs, 신장: 172.38±5.80 cm 체중: 63.45±8.56 kg, 경력 6.00±1.07 yrs)이 실험에 참여하였다. 잽 동작 시 제자리 스텝 사용이 운동역학적 요인들에 미치는 영향을 검증하기 위하여 대응표본 t-test(α = .05) 통계방법을 사용하였으며 다음과 같은 결과를 도출하였다. 첫째, W.S(with-step) 가 N.S(non-step) 보다 더 큰 충격력을 나타내었고, 근육의 활성도는 낮은 것으로 분석되었다. 둘째 W.S가 인체 분절의 전방의 속도의 영향을 미쳐서 골반과 발 분절이 더 빠르게 이동하는 것으로 분석되었다. 셋째, W.S는 골반의 회전 움직임이 더 빠른 것으로 나타났다. 넷째, W.S는 N.S보다 상대적으로 오른발과 왼발에 의해서 발생된 전방의 지면반발력이 더 큰 것으로 분석되었다. 이를 통해서 복싱 잽 동작 시 제자리 스텝의 사용은 지면반발력을 증가시켜 인체 분절의 이동 속도와 회전 움직임에 영향을 미치는 것으로 나타났다. 따라서 더 빠르고 민첩한 움직임을 가능케 하여 상대적으로 적은 근육의 사용으로도 더 큰 충격력을 내는 것으로 확인되었다. 그러므로 복싱의 잽 동작 시 효율적으로 상대방에게 큰 충격력을 전달하기 위해서는 제자리 스텝을 동반하는 것이 효과적으로 분석된다.

The purpose of this study was to analyze the effect of using standing step condition on biomechanical variables during jab in boxing. For this purpose, eight orthodox type college boxers(age = 20.38±0.52 yrs, height = 172.38±5.80 cm, body mass = 63.45±8.56 kg, career = 6.00±1.07 yrs) who without injury to the musculoskeletal system participated in the experiment over the last year. In order to verify the effect of biomechanical variables using standing step during jab in boxing, the paired t-test (α = .05) statistical method was used. First, W.S(with-step) showed a greater impact force than N.S(non-step), and muscle activity was analyzed to be low. Second, it was analyzed that the pelvis and foot segments move faster because W.S affects the velocity of the anterior segment of the human body. Third, the rotational movement of the pelvis was faster in W.S. Fourth, W.S was analyzed to have greater ground reaction force in the anterior caused by the right and left foot than N.S. Through this, it was found that the use of the standing step during jab increases the ground reaction force the velocity and rotational movement of the human segment. Therefore, it was confirmed that it allowed a faster and more agile movement, and thus produces a greater impact force with relatively less muscle activity. Therefore, in order to effectively deliver a greater impact force to the opponent during the jab, it was effectively analyzed to accompany the standing step.
