Dynamic stability and load distribution in yoga physical education teaching: A stereoscopic analysis based on pressure plates

Effective stability and distribution of load are important in yoga practice. This is because it determines postural control, balance, and elimination of injuries. The current training and coaching strategies are based on visual observation and verbal cues without the means for quantifying biomechanics. This cross-sectional study utilized pressure platform system and 3D motion capture system to measure plantar pressure, COP aperture and mediolateral balance shift during different yoga postures. To investigate the effect of the skill level on stability, candidates with different levels of experience were also targeted for inclusion in the study. The findings show that balancing postures are more asymmetrical and associated with larger COP displacement, which demands better NMC. Comparing the results of COP variability (SD = 0.63 cm) and weight distribution, it can be stated that experienced practitioners exhibit less variability and accurate balance, proving the idea that expertise positively affects stability. The Symmetry Index results revealed significantly greater variability for single-leg stance postures, suggesting that balance unevenness is an important factor during these asanas. These findings are particularly relevant to teaching yoga sessions, physiotherapy, and rehabilitation that can implement evidenced-based balance training. The study presents biomechanical feedback techniques as valuable for enhancing the approaches used in teaching yoga and improving stability training.
