Whole-Body Coordination and Spinopelvic Alignment During Yoga Standing Maneuvers: Comparing Practitioners With...

Area of Science:

• Biomechanics and Motor Control
• Human Movement Analysis
• Rehabilitation Science

Background:

• Understanding whole-body coordination is vital for designing effective movement interventions.
• Yoga standing maneuvers offer a complex testbed for analyzing human movement coordination.
• Limited research integrates spatiotemporal coordination and compensation across proficiency levels.

Purpose of the Study:

• To analyze whole-body kinematics and spinopelvic alignment during yoga standing maneuvers.
• To compare coordination and compensation strategies between yoga practitioners and non-practitioners.
• To identify benchmarks for movement assessment and the development of rehabilitation/robotic applications.

Main Methods:

• Analysis of whole-body kinematics, including 3D joint angle trajectories and spinopelvic alignment.
• Quantification across movement initiation, posture holding, and return stages.
• Application of Principal Component Analysis (PCA) and Continuous Relative Phase (CRP) analysis.

Main Results:

• Practitioners displayed reduced sagittal and rotational spinopelvic motion and enhanced proximal trunk-pelvis coordination.
• Non-practitioners relied more on distal joints (e.g., ankles) and utilized compensatory joint trajectories.
• Distinct thoracic contributions to spinopelvic alignment were observed between practitioners and non-practitioners.

Conclusions:

• Motor proficiency and task complexity significantly influence whole-body coordination and postural control.
• Practitioners exhibit more adaptive and efficient movement strategies during complex standing tasks.
• Quantitative benchmarks can inform movement assessment and guide the development of assistive technologies.
