Abstract

This study examined the response of the EMG of URA, LRA, IO, EO and RFM of various types of abdominal motion (crunch, spine V-up on ball, prone V-up on slide board, prone V-up on TRX, and prone V-up power wheel). The subjects performed anisometric contact of abs during these exercises. Tests have shown that there were no statistically significant differences between EO, URA and LRA between any movements. However, during the inspection of IO, the positive-wawed V-up motion showed significantly greater muscle activity than during the slide movement. Also, EMG activity during crunch was significantly lower than any other five exercises. These results indicate that in the implementation of equilateral absolutism, the equipment-free based exercise gives an impetus similar to equipment-based exercise. Abdominal muscle tissue is considered one of the five components that make up an individual's core. The abdominal muscles also ensure proper functioning of the lumbar spine. Although all abdominal muscles contribute to lumbar stabilization, TA & IO has been shown to perform major stabilizers.

본 연구는 여러 형태의 복부 운동(crunch, spine V-up, prone V-up on ball, prone V-up on slide board, prone V-up on TRX, and prone V-up power wheel)을 하는 동안 URA, LRA, IO, EO and RF의 EMG 반응을 조사했다. 대상자들은 이러한 운동을 수행하는 동안 복근의 isometric contraction을 수행했다. 테스트 결과 EO, URA, LRA는 어떠한 운동 간에도 통계학적으로 유의한 차이가 없었다. 하지만, IO를 검사 시에, 양와위 V-up운동은 slide운동 시 보다 유의하게 더 큰 근활성도를 보여주었다. 또한, crunch동안 EMG활성도는 다른5가지 어떠한 운동보다 현저히 적었다. 이러한 결과들은 등척성 복근 운동 시행 시에 장비가 없는 기반 운동이 장비 기반 운동과 유사하게 자극을 준다는 것을 나타낸다. 코어 강화는 오래 동안 운동 컨디셔닝과 수행능력의 핵심 구성 요소로 알려져 왔다. 복부 근육 조직은 개인의 코어를 구성하는 5가지 중 하나의 구성요소로 여겨진다. 복부 근육은 또한 요추의 적정한 기능을 보장한다. 모든 복부 근육이 요추 안정화에 기여하지만, TA & IO가 주요한 안정화(stabilizers)를 하는 것으로 보여주었다.
