A Study of Electromyographical Muscle Activation during Garudasana Performance in Adult Male Practitioner’s

Abstract

Purpose: The present study main objective was to assess electromyographical (EMG) activity of the tibialis anterior muscle during the garudasana performance among adult male yoga practitioners.

Methodology: For this purpose, cross-sectional study of eight healthy university-level male yoga participants with a mean age of 20.37 years were conducted by using purposive sampling technique for the present study. EMG data were recorded by using Biolite four-channel system with surface electrodes placed at tibialis anterior muscle site. Further, selected male subjects performed garudasana from 0 second to 30 seconds and the scores of muscle activity of tibialis anterior were recorded (i.e., 0 second, 10 seconds, 20 seconds, and 30 seconds) in micro-volts respectively.

Findings: Descriptive statistics and one-way-anova analysis were applied to determine the variations in muscle activation levels. Moreover, the results of the present study were revealed the highest mean activation at 10 seconds (ie., 34125.66 µV.) in tibialis anterior muscle and also indicating the greater neuromuscular demand during the early postural adjustment phase. But, no statistically significant differences were founded between the different time intervals (p > 0.05) which demonstrate consistent muscle activation recruitment once balance was achieved during the garudasana performance.

Conclusion: Hence, the findings of the present study were concluded that tibialis anterior muscle is key stabilizer for maintaining equilibrium in single-leg postures performance upto 30 seconds duration.
