Introduction: Core stability is thought to be a determinant factor for effective motor performance in most sport fields. Thus, there are lots of methods and exercises to strengthen core muscles. In recent years, Suspension exercises have been introduced as an effective method to improve core stability among athletes and nonathletes. However, the activity of core muscles during different suspension exercises has not been reported and compared to each other, yet. In this study, we interrogated the activation of selected core muscles during suspension core exercises in healthy active women.
Methodology: 15 active volunteer students of physical education of Kharazmi University of Tehran were selected by random. Surface electromyographic data were collected on rectus abdominis, external oblique, erector spine lumbalis, and superficial lumbar multifidus while performing lunge, bridging and plank under unstable condition using TRX. Resulting muscle activation data was amplitude normalized and root mean square activation was then determined over the full three second duration of the exercises.
Results: Different levels of muscle activation were observed during the three different exercises. Rectus abdominis activation was greatest during plank exercise, while superficial lumbar multifidus activity peaked during feet suspended lunge and bridging. Considering all results, Front plank generated the highest activation of most abdominal muscles. The Lunge exercise generated the lowest muscle activation.
Discussion: Among the investigated suspension workouts, Front plank was found to have the strongest potential strengthening effect on core muscles. Also, suspension training was found to generate relatively high levels of core muscle activation when compared with previous studies on traditional methods of core exercises on stable surfaces.
