Muscle Activation Dynamics during Karnapidasana Performance in Trained Yoga Male Subjects: An Electromyographical Analysis

Abstract

Background: Electromyography (EMG) was utilized to investigate muscle activation dynamics of the sternocleidomastoid (SCM) muscle during karnapidasana, an advanced yoga posture involving deep spinal and cervical flexion. Methodology: This study involved eight trained male yoga students performing karnapidasana while EMG signals were recorded to analysed the SCM activation at specified intervals (i.e., 0 second, 10 seconds, 20 seconds, and 30 seconds). Results: Statistical analysis of data were exhibited the relatively stable mean EMG activation values across these intervals with no statistically significant differences (p = 0.892) which were indicated sustained and consistent engagement of the SCM muscle throughout the posture. Findings: These findings were highlighted the SCM's crucial role in maintaining neck stabilization during of karnapidasana performance. The stability of EMG activity supports the asana’s reported benefits in improving neck muscular strength, spinal flexibility, and neuromuscular control. Conclusion:  This study provides neuromuscular evidence that substantiates karnapidasana’s therapeutic potential in rehabilitation, particularly for conditions involving cervical dysfunction and postural management.
