Background: There have been very few studies involving swan motion during pilates exercises, and there is also insufficient scientific evidence to support the fact that Pilates swan motion strengthens specific muscles.
Objectives: Firstly, the purpose of this study was to evaluate the effect of 5 types Pilates swan motion (swan basic (SB), swan push-up (SP), swan holding posture (SH), form roller-based swan (SF), and circle-based swan (SC)) on muscle activity of deltoideus p. acromialis (DA), infraspinatus (IP), trapezius (TP), latissimus dorsi (LD), and erector spinae (ES). Secondly, the purpose of this study was to suggest an effective Pilates swan motion for strengthening muscle strength of each targeted muscle.
Methods: Twenty-four healthy men in their 20s participated and all participants were measured muscle activity in DA, IP, TP, LD, and ES muscles by electromyography (EMG) during 5 Pilates swan motions (SB, SP, SH, SF, & SC). The measured values were expressed as relative voluntary contraction (%RVC) values based on the SB.
Results: The %RVC values representing the muscle activity of DA and TP were significantly higher in SH and SP than in SC, SF, and SB (p < .001). The %RVC values of IP and LD were significantly higher in SH and SC than in SF, SP, and SB (p < .001). The %RVC value of ES was were significantly higher in SH than in SP, SC, SF, and SB (p < .001).
Conclusion: The application of SP, SC, and SH Pilates swan motion is an effective method to activate the back muscles of the trunk.
