Methods: 6 male(age:34.1±3.31,height:177±1.79cm,weight:72.4±4.41kg) and 6 female (age:36.5±3.94,height:162.1±6.24cm,weight:52.1±3.71kg) yoga instructors participated in the study. The Vicon Motion Capture System (200Hz), Kistler force platforms (1000Hz), and T＆T Medilogic pressure pad were used to collect the kinematics and kinetic data. Nonparametrics Mann-Whitney was used for statistics. The significant level of difference was set at α=.05. Results: In the sagittal plane, the angles in the spine, the hip and the knee during the performance of headstand were the same to those in standing. No gender effect was found during performing yoga pose headstand. conclusion：Although the headstand has its difficulties. In particular, the angles of the ankle, knee, hip and spine, was be a line formed, and vertical with the ground state, it more difficult to maintain a stable equilibrium. However, the long-term practice yoga instructors are able to complete the consistent headstand. In addition, When yoga practitioners perform headstand correctly with good alignment, the Biomechanical characteristics didn’t affect by gender.壓力墊平衡關節角度運動學性別pressure padbalancejoint angleskinematicsgender
