초록
[목적] 본 연구는 관성 과부하 원리를 접목한 12주간의 반응 신경계 훈련에 따른 골프 스윙 협응 구조의 변화를 규명하는 데에 목적이 있다. 반응 신경계 훈련은 학습자의 잘못된 동작을 극대화함으로 인하여 올바른 협응 구조를 이끌어내는 신경학적 훈련이다. 이에 골프 스윙의 순차적 협응 패턴에서 주로 가속 회전 전략이 나타나는 초보자에게 관성 과부하 동작을 반응 신경계 훈련 기법으로 선정하였다. [방법] 12주간의 골프 수행력과 신체 협응 패턴의 변화 과정을 살펴보기 위해 공 추적 장비(launch monitor)와 IMU 관성센서를 활용하였으며, 평가는 사전 검사와 세 번의 사후 검사에 걸쳐 실시하였다. 30명의 남자 사관생도는 총 세 집단으로 구분되어 매주 두 번씩 골프 스윙 연습과 집단별 세부 훈련을 병행하여 진행하였다. [결과] 실험 결과, 사전 검사에서 관측되지 않았던 근위 분절의 감속 회전 타이밍은 훈련이 진행됨에 따라서 세 집단 모두 점차 단축되는 경향을 보였지만 반응 신경계 훈련 집단이 압도적으로 향상되는 결과를 나타내었다. 이로 인해, 반응 신경계 훈련 집단은 몸통과 손목의 최대 각속도가 비교집단에 비해 통계적으로 유의미하게 증가하였으며 결국 타구의 비거리와 정확성 측면에서도 긍정적인 영향을 미치게 되었다. [결론] 반응 신경계 훈련은 골프 숙련자의 감속 회전 전략을 학습하는데 효과적인 훈련 기법으로 판단되며, 앞으로는 더욱 창의적이고 과학적인 분석 방법을 다양한 운동 종목과 기술수준에 접목하는 후속 연구를 기대한다.
Abstract
[Purpose] We examined the influence of reactive neuromuscular training (RNT) on golf swing coordination. RNT aims to induce proper coordinative movement by exaggerating the performer’s mistakes. Therefore, we applied RNT using inertia overloading to golfers who have problems with kinematic sequence during a golf swing. [Methods] To examine the effect of 12 weeks of RNT on golf swing coordination, we employed a ball tracking system (launch monitor) and motion analysis system (inertia sensors) were taken on four consecutive periods (pre-test and post-tests 4, 8, and 13 weeks later). Thirty Korean male cadets were divided into three groups based on inertial loading and practiced 7-iron golf swings combined with specific group tasks twice per week. [Results] At pre-test, most participants reached maximal angular velocity near the impact timing (95-100%). However, the deceleration timing of the maximum angular velocity of the proximal segments gradually moved toward mid-downswing as the training sessions proceeded, with the RNT group ultimately outperforming the two control groups. Additionally, the RNT group showed a significantly higher maximum angular velocity in the thorax and wrist. [Conclusion] Our results suggest that RNT can be sufficient to elicit and effective whole-body coordination pattern. Considerable follow-up research is needed on the use of RNT for various sports tasks and the effects of expertise on RNT results.
