Finding Centre of Gravity of Posture Sequences of Asanas Using Skeletal Information as Joint Angle Differences

Maintaining proper physical posture is essential for pain free life. This is more important while practicing exercise, sport and yoga asana. If not, miss-alignment of joints will lead to issues like fracture, muscle pain, stress on spine. Precise depictions of postures play a vital role while using assistive technology while practicing yoga. Maintenance of correct posture is in other words maintaining the Centre of Gravity (CoG) in correct location for that posture. By means of CoG, trainer module of assistive systems can identify the strain on any particular body part. By looking into CoG of consecutive postures, trainer can instruct corrections to maintain the postures. CoG value represents whether proper weight distribution is there among the body parts. This paper analyses the variation in CoG of various postures among the practitioners. Evaluation is done withbothmale and female yoga asana practitioners, half of them with prior practice. We identified that male practitioners have better CoGvaluesthan female, Similar is the observation for the practitioners with prior practice exposure also
