인클라인 벤치프레스에서 그립 넓이가 주동근의 근피로에 미치는 영향

Abstract

The myoelectric signal of the sternoclavicular and clavicular portions of the pectoralis major, the anterior deltoid, and the triceps brachii of 7 healthy men was collected during an incline bench press with different grip widths. Grip width(narrow, mid, and wide) was varied to determine how these factors influence muscle fatigue(median frequency, MF) during the incline bench press. A wide grip resulted in increased muscle fatigue for the anterior deltoid and the clavicular portion of the pectoralis major. And, moving from wide to narrower grip widths increased triceps fatigue. The muscle fatigue in sternoclavicular portion of the pectoralis major not occurred irrespective of the grip widths. Considering the changes that occur during changes in grip width, the choice of grip position should be determined by the attempts to train specific muscle groups.
