“…Senior yoga practitioners with unstable standing balance may benefit from practicing these poses near a wall or chair in order to provide lateral stability. Previous research also showed that ankle joint loading was highest in single-leg poses [19]. Patients with a history of ankle injury, along with the degeneration of cartilage, should be cautious when performing these poses.…”

“…Although this study did not include elderly subjects, previous research [19] indicated that the younger population experienced larger joint moments about both ankles while performing common standing yoga poses than their older counterparts, perhaps suggesting different load distribution strategies by the two populations. EMG activation and the coordination of ankle muscles during balance tasks also change with age [29].…”

“…For help in a discussion on patients regarding their rehabilitation program after ankle injury or surgery, Mears et al (2019) used motion capture and force plates to assess the range of motion and joint moments of the ankle while practicing seven yoga poses that were considered to challenge the ankle joint [19]. Their findings in joint moments showed that the joint loading was highest during single leg poses.…”

Standing yoga poses strengthen a person’s legs and helps to achieve the goal of musculoskeletal rehabilitation, but inadequate exercise planning can cause injuries. This study investigated changes in the electromyogram and joint moments of force (JMOFs) of lower extremities during common standing yoga poses in order to explore the feasibility and possible injury risk in dealing with musculoskeletal problems. Eleven yoga instructors were recruited to execute five yoga poses (Chair, Tree, Warrior 1, 2, and 3). The results revealed significant differences in hip, knee, and ankle JMOFs and varying degrees of muscle activation among the poses. Among these poses, rectus femoris muscle activation during the Chair pose was the highest, Warrior 2 produced the highest muscle activation in the vastus lateralis of the front limb, while Warrior 1 had the highest muscle activation in the vastus medialis of the back limb. Therefore, all three poses can possibly be suggested as a therapeutic intervention for quadriceps strengthening. Warrior 1 was possibly suggested as a therapeutic intervention in order to reduce excessive lateral overload of the patella, but the possible adverse effects of Warrior 2 with the highest knee adductor JMOF in the back limb could raise joint reaction forces across the medial condyles. In single-leg balance postures, Warrior 3 had unique training effects on the hamstring, and is therefore suggested as a part of hamstring rehabilitation exercises. The Tree pose induced low lower-extremity JMOFs and a low level of thigh muscle activations when it was performed by senior instructors with excellent balance control; however, for yoga beginners with insufficient stability, it will be a useful training mode for strengthening the muscles that help to keep one upright. This study quantified the physical demands of yoga poses using biomechanical data and elucidated the structures and principles underlying each yoga movement. This is crucial for yoga practitioners.

“…In both asanas, the symmetry of trunk position in relation to the lower limbs was observed regardless of the supporting limb, which is proper biomechanically. Mears et al [26] used a motion capture system to evaluate the hip joint in common yoga poses such as garudasana, among others. They claimed that this pose included extreme hip motion related to higher adduction and internal rotation.…”

Introduction: Yoga is classified as a form of complementary and alternative medicine. It can be used in many disciplines including: physiotherapy, medicine and sport. The objective of the study was to identify possible biomechanical problems during yoga practice, to minimize the risk of injury. Case presentation: Objective evaluation of the symmetry of asanas, balance, stability and muscle tension was provided in case of a 37-year-old woman, practicing mainly aerial and Hatha yoga for 6 years. The bigger body tilt and deviations in Center of Pressure parameters were observed in tadasana during forward examinations. In tadasana, the highest muscle activity was observed in the rectus femoris. In the case of forward tadasana observation, the highest activity was found in the gastrocnemius and in the lumbar portion of the erector spinae. During backward tadasana trial, the most active were tibialis anterior and rectus femoris muscles. In garudasana and natarajasana, the symmetry of the trunk position in relation to the lower limbs was observed regardless of the supporting limb. In the same way, Center of Pressure parameters in garudasana were similar regardless of the supporting limb. However, in natarajasana the higher COP displacement parameters were observed in the case of the non-dominant supporting limb. As for the electromyographic evaluation of garudasana and natarajasana, the highest muscle activity was observed in the lumbar portion of the erector spinae. In chakrasana, a slightly greater angle of the hip extension was observed in the left hip. A higher muscle activity in chakrasana was observed in the lumbar portion of the right erector spinae. In sirsasana, no significant displacements of the cervical spine were observed but a higher activity of the left sternocleidomastoid muscle was found. Conclusion: With the use of objective movement analysis possible biomechanical problems were identified. Attention should be paid to the normalization of the tension in the lumbar part of the right erector spinae and the right sternocleidomastoid muscle, as well as to the balance training in positions on non-dominant lower limb. Objective movement analysis can be a useful tool for instructors or physiotherapists to adjust yoga programs and to correct asanas in order to avoid future injuries.

“…The stress and strain inside the three axes of motion were charted using mean and standard errors (SE). One shortcoming with this model would be that the MoCap features represent movement between both the shank & foot sections and need to account for the numerous joints within the foot [163].…”

Yoga has been a great form of physical activity and one of the promising applications in personal health care. Several studies prove that yoga is used as one of the physical treatments for cancer, musculoskeletal disorder, depression, Parkinson's disease, and respiratory heart diseases. In yoga, the body should be mechanically aligned with some effort on the muscles, ligaments, and joints for optimal posture. Postural-based yoga increases flexibility, energy, overall brain activity and reduces stress, blood pressure, and back pain. Body Postural Alignment is a very important aspect while performing yogic asanas. Many yogic asanas including uttanasana, kurmasana, ustrasana, and dhanurasana, require bending forward or backward, and if the asanas are performed incorrectly, strain in the joints, ligaments, and backbone can result, which can cause problems with the hip joints. Hence it is vital to monitor the correct yoga poses while performing different asanas. Yoga posture prediction and automatic movement analysis are now possible because of advancements in computer vision algorithms and sensors. This research investigates a thorough analysis of yoga posture identification systems using computer vision, machine learning, and deep learning techniques.INDEX TERMS Yogic posture recognition, optimal posture, machine learning methods, deep learning methods.
