초록
[목적] 본 연구의 목적은 공의 구속에 따른 집단 간 지면반력(ground reaction forces, GRF)과 골반 및 몸통에서 나타나는 각속도의 패턴을 비교하는 것이다. [방법] 총 29명의 연구대상자가 모집되었다. 연구대상자는 공의 구속이 높은 순서대로 high ball speed group(HG), medium ball speed group(MG), low ball speed group(LG) 총 3그룹으로 분류되었다. 집단 간 GRF와 골반, 몸통의 운동학적 비교를 위해 SPM1D 일원 배치 분산 분석 및 Bonferroni 사후 검정이 수행되었다. [결과] 축발의 추진력과 합력이 HG가 LG보다 더 큰 결과를 나타냈다(p <.001). 디딤발의 제동력은 HG가 LG보다 더 큰결과를 나타냈으며(p <.008), 디딤발의 수직 지면반력은 HG가 MG보다 더 큰 결과를 나타냈다(p <.003). 또한 디딤발의 합력에서는 HG가 MG와 LG보다 더 큰 결과를 나타냈다(p <.003). [결론] 축발과 디딤발의 GRF는 구속에 따른 집단 간 유의미한 차이가 있었다. 따라서 공의 구속과 관계되는 축발과 디딤발의 GRF를 극대화하기 위한 투구 전략이 필요하다.
Abstract
PURPOSE This study aimed to analyze the differences in ground reaction forces (GRF) and pelvis and trunk kinematic patterns between groups based on ball speed during pitching. METHODS Twenty-nine males were recruited for this study. Participants were categorized based on ball speed into high (HG), medium (MG), and low (LG) ball speed groups. Statistical analysis was performed using one-dimensional statistical parametric mapping (SPM1D) one-way analysis of variance to compare GRF and pelvis and trunk kinematic patterns, followed by Bonferroni post-hoc tests. RESULTS Drive leg anterior and resultant GRF were greater in the HG than in the LG (p<0.001). The posterior GRF of the stride leg in the HG was greater than in the LG (p<0.008). Additionally, the vertical GRF of the stride leg was greater in the HG than in the LG (p<0.003), as was the resultant GRF of the stride leg (p<0.003). CONCLUSIONS The GRF of the drive and stride legs was significantly related to ball speed, indicating that a pitching strategy to maximize the GRF of the drive and stride legs is required.
