The Effect of Plank Exercises with Hip Abduction Using Sling on Trunk Muscle Activation in Healthy Adults

Abstract

Purpose: The purpose of this study is to investigate the effects of healthy persons performing a plank exercise with hip abduction and use of sling on trunk muscle activity. Methods: Twenty-three subjects participated in this study. Muscle activities of the multifidus, rectus abdominis, external oblique and internal oblique were assessed with electromyography (EMG) while the subjects performed 6 various types of plank exercises in random order.Results: There was a significant difference in multifidus and internal oblique on the supported side and the multifidus, external oblique, and internal oblique on the elevated side (p< 0.05), and differences in plank methods were significantly higher in the multifidus, rectus abdominis, external oblique, internal oblique of the supported side and the rectus abdominis, external oblique and internal oblique on the elevated side (p< 0.05). In addition, post-hoc analysis of the various plank methods showed that muscle activity was significantly higher during the general plank exercise compared with the knee-supported-in-sling plank exercises (p < 0.05), and was significantly higher with the ankle-supported-in-sling plank exercises compared with the general plank exercise. Conclusion: There was greater trunk muscle activity with plank exercises performed with the ankle-supported-in-sling and hip abduction plank exercises compared with the general or knee-supported-in-sling plank exercises. Through this study, various plank exercises have been discovered that can be selected at different intensities for core muscle training purposes based on trunk muscle strength.

Comparative Analysis of the Electromyography Activity of Core Muscles During Balance Pad- and Sling-assisted Exercises

“…Although the exercises were not the same as the present study, a previous study indicated that the muscle activities of the ipsilateral GM, erector spinae, and contralateral latissimus dorsi muscle on the unstable side, i.e., the side with the hip joint extended, were increased by the prone hip extension exercise [31]. Another study show that in a variety of flat support motions, in sling training for ankle support, the activity of trunk muscles was significantly increased [32]. In this study, during the leg-lifting with flat support exercise, the unstable side was supported by an unstable surface.…”

Electromyographic Activity of the Rectus Abdominis Muscle during Physical Conditioning Exercises: A Systematic Review

“…After analyzing titles and abstracts, 146 potentially relevant studies were selected. After analysis of the full texts, 13 studies are considered eligible and are included for further analysis: [18], [19], [20], [21], [22], [23], [24], [25], [26], [27], [28], [29], [30].…”

The Effects of Sling and Resistance Exercises on Muscle Activity and Pelvic Rotation Angle During Active Straight Leg Raises and Pain in Patients with Chronic Low Back Pain

“…가로면에서의 회전 운동은 몸통 중심 안정화에 특화 된 기능 훈련으로 점진적으로 더 큰 저항과무게를 주어 시행한다 (Akuthota et al, 2008). 몸통 회전 저항운동 기 구(torso rotation machine)는 기구를 잡은 팔이 레버의 역할을 하며 회전중심축에서 몸통 회전 힘을 토크로 변환하여 거리가 멀수록, 저항 부하가 클수록 더 강한 표면근의 근력을 요구하게 된다 (Bak et al, 2017). 특히 가로면에서의 저항운동은 배 주변 근육을 강화하여 몸 통 안정성을 유지하는데 큰 도움이 된다 (Akuthota et al, 2008 (Liebenson et al, 2009).…”
