This paper is concerned with the numerical investigation of the landing impact characteristics of sport shoes to the landing mode. In most court sport activities, jumping and landing are fundamental motions, and the landing motion is largely composed of forefoot and rearfoot landing modes. Since the landing impact may, but frequently, lead to unexpected injuries of players, the investigation of its characteristics and the sport shoes design for reducing it are of a great importance. To investigate the landing impact characteristics to the landing mode, we construct a shoes-leg coupled model and carry out the numerical simulation by an explicit finite element method.

최근 들어 부강을 방지하고 경기력을 향상시킬 수 있는 스포츠화를 개발하기 위해 신체운동학과 생체역학을 반영한 연구가 전세계적으로 활발히 수행되고 있다. 하지만, 이러한 연구의 성골 여부는 스포츠화와 발의 동적 거동, 특히 착지 충격 특성 평가의 신뢰성에 절대적으로 좌우된다. 그 이유로는 코트 스포츠운동에 있어서 착지충격력이 예상치 못한 부상과 경기력의 주요한 요인이기 때문이다. 이 연구는 맨발과 대표적인 코트 스포츠화의 착지충격 특성을 평가하기 위해 유한요소 해석을 적용하였다. 사람의 발과 신발사이의 연계효과를 정확히 반영하기 위해 별도의 실험 데이터에 의존하지 않는 완전한 3차원 발-신발 FEM 모델을 생성하였다. 수치 시뮬레이션을 통해 FEM 모델의 신뢰성을 평가함과 동시에 여러 가지 스포츠화의 GRF, MIF 및 주파수 응답과 같은 착지충격 특성들을 분석하였다.

Objective: The purpose of this study was to evaluate the effect of passive-acute temperature therapy of the femoral muscle and dynamic warm-up on the countermovement jump performance. Method: Twenty male track and field athletes from national team underwent three treatments applied on the femoral muscles; cold temperature treatment, thermal treatment and dynamic warm-up. The variables extracted at 2 time points (pre-measurement and post measurement) were the temperature of the left and right femoral muscle, displacement & velocity of centre of mass, peak power out, range of motion and moment & power of the knee joint. Results: There was a statistically significant difference in the temperature of the femoral muscle according to measurement time which was high in the order of thermal treatment, dynamic treatment and cold treatment. The jump height was the highest in the dynamic warm-up with no statistically significant difference for the range of motion of the knee joint. The peak power out at dynamic warm-up and the power of the knee joint were statistically significant according to the treatment and measurement time. Conclusion: Local cold and thermal treatment of femoral muscles at ambient temperature did not improve jump performance, while dynamic warm-up was considered to be effective for maintaining the performance of the activities that require strong muscular power.
