| Research purposes:Yoga is a popular in our country, yoga asana with distinctive characteristics, many members simply imitate, lack off a scientific data on the yoga teaching for reference. The representation of the balance of Hatha yoga asana, Natarajasana, as a senior balance asana with its graceful gesture interpretation of the perfect combination of strength and flexibility, In order to standardize the technique, analysis to solve common problems in the teaching practice, it is necessary to use the means of kinematics of its kinematic characteristics are studied.Research methods:This research techniques from two aspects of external and internal characteristics of the kinematic characteristics of Hatha yoga Natarajasana, adopting Qualisys Track Manager infrared imaging testing system, the test object to a high level and a beginner, the knee joint Angle, and the location of the shoulders and hips in space, changes in the velocity of the upper limb and lower limb were analyzed.Research conclusions:The high level of trainer’s leg knee joint in coronary below average of 89.38 °, basic can meet the requirements of achievement method of the thigh line parallel to the ground, the calf tibial perpendicular to the ground; Average sagittal alignment is 132.84 °, accord with human body kinematics principle; Levels below the average of 105.74 °, near the achievement method of be particular about the vertical Angle.. In the horizontal plane supporting leg knee joint Angle in the balance phase (T3) average of 155.02 °, did not meet the requirements of power left leg unbend, perpendicular to the ground, but the accord with human body kinematics principle. Achievement method requires the shoulder hip level in the balancing stage (T3) 18 °——20 ° rotation Angle. The movement of the hips and shoulders state is rear up and turn to the right. The whole speed change over time:the characteristics of fast, slow, slow, fast, is not completely in the sense of constant motion. Clutching his ankle stability, balance and fall back three stages of changes in the most obvious, prone to injury, when teaching should be given attention. The beginner in the balance phase (T3) of knee joint is safe and effective space Angle:supporting leg level is 160° ±5°;The support legs sagittal is 120°;Coronal about 50°;Level of about 60°Research proposal:Recommended for follow the principle of discrimination and is suitable for load and sublevel teaching. Take the transform the training method, reasonable arrangement of teaching content. For different training level of students to take hard method and reduction method. Reasonable arrangement of flexible quality and power quality of practice. Suggest language teaching more scientific, adopt suitable teaching methods and auxiliary tool. Let students understand the basic kinematics characteristics of Hatha yoga Natarajasana, prevent the occurrence of sports injury. |
