A Study Of The Kinematic Characteristics Of Hatha Yoga

In the modern society of healthy,yoga has become many people pursue healthy way of a sport.Hatha yoga is different from other yoga is that it mainly composed of asana practice.Hatha yoga is not only pay attention to the practice of postures,also pay attention to the body "in correct position" technical requirements.Because of the special way of teaching,oral body to teach yoga makes it hard for training standard and unified,lack of quantitative evaluation index.This article mainly to the kinematics of six types of hatha yoga postures characteristic as the research object,through the literature material law,video analysis,mathematical statistics,the use of yoga postures to Kwon3 D kinematic joint Angle index were determined,from the Angle of kinematics of observation and analysis of static and dynamic Angle data of each style to kinematics characteristics of the six class explores yoga postures.Which standard has a quantitative evaluation index postures.Practitioners practice at the same time can be compared with the professional yoga instructor research,find out the differences.Can also be for yoga coaches guide junior is the practice of yoga.For hatha yoga is a technical requirements to provide theoretical foundation,promote the popularization and development of hatha yoga.This paper,based on the traditional classification method of hatha yoga after selected the basic stance,before bending,bending,lateral bending,torsion and inverted at the beginning of six kinds of postures of 10,intermediate postures,through statistics and analysis,the following conclusions.(1)Static postures of joint Angle characteristics:Tadasana as basic stance,conform to the standards of human anatomy position,posture symmetry state.Do mountain type body posture to meet the requirements of three aspects.Look from the front,head in a neutral position of the body,shoulders,hips,knees relative to both ankles symmetry;Look from flank,hip,knee,ankle center of rotation on a straight line,directly above the double ankle head;From the inside of the body analysis,the spine does not exist reverse.Samakonasana for practitioners from the point of view of the overall posture,to achieve "two parallel,two vertical" : his arms and upper should be parallel to the ground,torsos and legs of a right Angle,Angle and legs vertical to the ground.The second legs and spinal shape to conform to the mountain type characteristics.Uttanasana with similar characteristics with the right Angle,focus were observed before and after the spine does not exist bending phenomenon and abdominal close legs thighs.Anuvittasana look from the front,shoulders,hips and knees relative to both ankles is symmetrical,the spine lateral flexion;Viewed from the side,bending of the spine.For the spine after bending condition,mainly through the external form is in line with the spine Angle of three segments of the numerical relationship of neck and chest < lumbar flexion Angle < thoracic and lumbar segment Angle;From the internal spine reverse phenomenon does not exist.Chandrasana stand up after bending,the difference is that shoulder joint Angle is greater than the stand after bending,directly above the left foot ankle left knee joint.In the case of double hip is a guarantee,right thigh and instep try to stick to the ground Surface.Ardhamatsyendrasana reverse and torsional torso posture,spine torsion Angle is close to 90.Difference is mainly in the legs,standing reverse legs agree with mountain type,the king of fish has its own characteristics.All landowners triangle stretch and Tiryaka Tadasana characteristics are basically identical.From the body side,from the beginning to the ankle should be on a plane,shoulder,hip,knee and ankle center of rotation should be on the same straight line;From the internal spinal torsion Angle is no significant change.The difference is that a triangle stretch double hip Angle should grasp the left hip ankle Angle is less than the right hip ankle Angle.Salamba Sarvangasana characteristics similar to mountain type,but the neck and chest Angle is greater than the mountain type data.At the same time when doing sarvangasana must follow the principle of "1234".(2)Dynamic characteristics of shoulder joint pet-name ruby: studied three postures shoulder joint Angle line chart on the move,a trapezoid.Shoulders attention early observation good initial Angle,correct in a timely manner.In the process of the movement of the shoulder joint,avoid by all means in order to achieve standard postures scoliosis caused by shoulder joint in the clasp.At the same time to ensure that the shoulders of the shoulder joint is open fully,avoid Angle of shoulder joints caused by inconsistent spine appears to reverse the situation,to ensure the stability of the shoulder joint Angle at the same time.Regression phase,led the whole torso back up his arms,and returning to the original into the body postures mountain type.(3)Attending dynamic hip characteristics: from the start to the end of the postures of postures,double hip position held at the same time must pay attention to increase or reduce the hip joint Angle,and strengthen the body control aspects of the practice,to ensure the stability of the asana practice.Pay attention to the step by step in practice.(4)Postures of focus features: as a standing pose,Tadasana、Uttanasana、Samakonasana、Tiryaka Tadasana、Triangle stretch、Ardhatandasana the center of gravity of the height of 0.57 m,0.44 m,0.56 m,0.58 m,0.46 m,0.57 m,accords with the characteristics of human body’s center of gravity is located at the third lumbar vertebra,And meet the following relationship;Samakonasana> Uttanasana,Anuvittasana>Chandrasana,TiryakaTadasana>Trianglestretch,Ardhatandasana>Ardhamatsyend rasana.
