국문 초록

본 연구의 목적은 스포츠 현장에서 운동 중단을 예측할 수 있는 운동 속도 감소와 관련된 근전도 신호의 변화를조사하는 것이다. 성인 남성 18명을 대상으로 10RM 백스쿼트를 실패 지점까지 실시하고, 운동 속도 및 속도 손실, 안쪽넓은근 및 가쪽넓은근의 근전도 신호를 운동 중 반복 횟수에 따라 평가했다. 그 결과, 10RM의 부하에 대해속도를 조정하지 않고 기존 스쿼트를 수행할 때 속도, 근전도 신호가 점진적으로 변화했지만, 중간 및 후반 반복횟수(6~8회)에서 속도 손실, RMS 증가, MDF 감소가 컸다. 따라서 중강도 저항 운동에서 높은 근활성을 얻기 위해서는속도 손실 후 실패에 가깝게 반복하는 것이 가능하며, 세트 반복 횟수의 절반을 수행하는 저항운동 프로토콜을 구성하면 피로를 최소화할 수 있다.

영문 초록

The purpose of this study was to investigate the changes in Electromyography(EMG) tendency associated with decreased exercise velocities that can predict exercise interruption in the field of sports. Eighteen adult men underwent 10RM Squat to the point of failure, and EMG (RMS, MDF) of exercise velocity (MPV, MPV loss), vastus medialis and vastus lateralis were assessed by the number of repetitions during exercise. As a result, the speed, RMS, and MDF gradually changed when performing traditional squats without adjusting the speed for a load of 10RM,but the speed loss, RMS increase, and MDF decrease were large in the middle andlate sets (6 to 8 times). Therefore, to obtain high muscle activity in moderate intensity resistance exercise, it is possible to repeat close to failure after velocity loss, and fatigue can be minimized by constructing a resistance exercise protocol that performs half of the set repetition.
