체성감각 처치를 초보자에게 적용한 케틀벨 투암 스윙의 운동역학적 효과 비교: 관절 가동범위와 근활성도를 중심으로 (Biomechanical Comparisons of Kettlebell Two-arm Swings according to Somatosensory Interventions for Beginners: Focusing on Joint Ranges of Motion and Muscle Activations)

초록

Objective: The purpose of this study was to investigate biomechanical comparisons of kettlebell two-arm swings after different somatosensory interventions on joint ranges of motion (ROM) and muscle activations.
Method: Fourteen kettelbell novices (age: 22.92±3.23 yrs, mass: 75.75±9.94 kg, height: 172.03± 5.49 cm), consisting of male college students, participated in this study and performed two-arm kettlebell swings in different conditions. Three different somatosensory interventions were the applications of heavy mass kettlebell (20 kg), taping on gluteus muscles, and unstable mat condition.
All subjects performed pre-intervention swings and post-intervention swings, respectively. Statistical analysis were performed on results of joint kinematics and electromyographies of major muscles.
Results: Results showed significant increases in ROM of hip and decreases in ROM of shoulder after unstable mat trials. In addition, the application of unstable mat during kettlebell swings induced higher muscle activations in gluteus maximus muscle during only upward phase of two-arm kettlebell swings.
Conclusion: For beginner, the application of unstable surface would increase in hip joint ranges of motion with enhancement of gluteus muscles.
