The Biomechanical Analysis Of Healthcare Taiji-palm Of Shuanglongxizhu Movement

Through visits to compose Professor Zhang Guangde, relevant experts and scholars, as well as long-term practitioners guide Qigong enthusiasts, they generally reflect the the health Taiji palm exercises "Shuanglongxizhu action more difficult. Performance:1, action, complex structure.2, a large range of activities.3complexes, the correspondence between the various parts of the body.4, parts of the body angular position of strict specifications.5, the direction of change is complicated, and the change of angle. The most difficult to grasp, teachers teaching and students could not master the technology of the action, the referee is difficult to judge, thus affecting the quality of the teaching and training of health Taiji palm, Taiji palm main difficulty action necessary health science testing and analysis.Drawing on previous research to guide Qigong representative from kinematics, dynamics and anatomical point of view, select health Taiji hands and the difficulty factor Shuanglongxizhu technical movement kinematics and EMG testing and analysis. Health Department of Beijing Sports University Professor Hu Xiaofei This study selected as a test object, kinematics, dynamics and surface electromyography study means study the Shuanglongxizhu technical movements.Infrared high-speed motion capture system (Motion Analysis Raptor-4, USA) using8lens subjects hip joint, knee, ankle, shoulder and elbow when the screen of each characteristic phase angle for statistical analysis; using Megal6guide trapeziums EMG on the right side, the right side of the pronto terse, right biceps the right deltoid (middle), and the right side of the rectus femoris, right biceps femoris, right tibia ago muscle, right medial, right lateral gastronomies and right side of the erector spine muscle11muscle analysis of the IEMG values and muscle activation order statistics; application Kistler force measurement platform subjects completed Shuanglongxizhu, course of action left foot in the direction of X, Y and Z-axis force changes in the value of the test analysis aims to provide teaching and training for the future work of the theoretical basis of the scientific findings:1. The beginning and the end of the fixed-action with a high degree of symmetry,2. Shuanglongxizhu action can exercise lower extremity strength, especially the quadriceps, biceps femoris, gastrocnemius, semitendinosus and semimembranosus muscle strength, improve the hip, knee, ankle, shoulder and the flexibility of the elbow, but also to exercise the body balance and coordination.3to determine a waist axis center position, full use of the waist muscle strength.4in unilateral Shuanglongxizhu operation, the left foot in the vertical direction on the trend is symmetrical in the horizontal direction on the same trend. Muscle activation order is followed by the external oblique, medial gastrocnemius, trapezius, tibialis anterior, biceps femoris, deltoid (middle), lateral gastrocnemius, biceps.5. Deltoid (middle) force in the entire course of action the largest the pronator teres exertion minimum, followed trapeziums, biceps femoris, erector spinae, rectus femoris, tibialis anterior, lateral gastronomies medial and biceps.
