초록
스쿼트는 장소에 제약 없이 효과적으로 하체 근력을 증진시킬 수 있는 운동이다. 스쿼트 시 잘못된 자세로 인한 부상이 빈번하게 발생하고 있으며, 부상을 예방하기 위해서는 적절한 각도를 유지하며 운동하는 것이 중요하다. 본 연구에서는 허벅지에 착용된 단일 관성 센서 모듈을 이용하여 스쿼트 각도를 측정할 수 있는 시스템을 개발하고 검증하였다. 스쿼트 각도를 측정하기 위해 각 관성 센서(가속도 센서, 자이로 센서)의 장단점을 상호 보완 하는 상보필터 알고리즘을 사용하였고, 임상 실험을 통해 각 상보필터 계수에 따른 스쿼트 각도의 정확도를 평가하였다. 분석 결과, 최적의 상보필터 계수를 기반으로 계산된 스쿼트 각도는 측각기에서 측정한 각도와 상관 계수 0.623와 편향 오차 –5.6°로 유의한 상관관계를 보였다.
Abstract
The squat is an exercise that can effectively improve the muscle strength of the lower body, which can be performed in a variety of places without restrictions on places including homes. However, injuries due to incorrect motion or excessive angles are frequently occurring. In this study, we developed a single sensor-based squat angle measurement system that can inform the squat angle according to the correct motion during the squat exercise. The sensor module, including the acceleration sensor and the gyro sensor, is attached to the user's thigh. The squat angle was calculated using the complementary filter complementing the pros and cons of acceleration and gyro sensor. It was found that the calculated squat angle showed the proper correlation compared to the squat angle measured by a goniometer, and the influence of the coefficient of the complementary filter on the accuracy was evaluated.
