Electromyographical Analysis of The Thigh Muscle During Four Yogasana

Abstract

The goal of the study was to examine the peak EMG at four lower body muscles during four different yoga poses performed by yoga practitioners. Materials and methods: Male Yoga practitioners (n= 11) were assessed for peak electromyography (EMG) of VM-Vastus Medialis, VL- Vastus lateralis, BF- Biceps femoris, ST- Semitendinosus, while performing four Yogasana: UK- Utkatasana, VB- Virabhadrasana II, UPE- Urdhva prasarita ekapadasana six, DOL- Dolasana (pendulum pose). Results: The UK induced the highest EMG for VM (124.5000 ± 25.36088), VL(124.2364 ± 27.35410), ST (106.6091 ± 32.77619),BF (96.6909 ± 29.34824),The VB II induced the highest EMG for the VL (102.0727 ± 32.96262), VM (100.4091± 16.30960), BF (84.5727 ± 28.63844), ST (86.2818 ± 26.07239).The UPE-Six induced the highest EMG for the VM (42.4364 ± 17.09025), BF (45.0636 ± 21.33440),ST (39.3727 ± 17.03315),VL (38.3636 ± 20.73612).The DOL induced the highest EMG for the VM (88.7455 ± 56.13069), BF (65.2545 ± 36.53172), ST (62.6455 ± 19.28302),VL (43.2545 ± 24.14255). However, between Yogasana, only the VM showed a significant (P < .000) * different EMG. Specifically, the UK induced greater VM EMG compared to UPE (82.064, P < .000), VB (57.973, P < .000) * Conclusions: Peak muscular activation in the four lowerbody muscles can change depending on how the yoga players treat the four differences. A declining pattern of peak EMG for the UK > VB II > DOL and UPE six Yogasana, however, indicates that variations between poses appear to be minimal, with the exception of the VM muscle.
