Kinematic and electromyographic analysis of the push movement in
tai chi - Correspondence to: Ms Chan, Department of Sports

Accepted 16 September 2002 Background: Tai chi is a form of
exercise derived from the martial art folk traditions of China.
The force used in tai chi includes different principles of
mechanical advantage. No studies on the kinematic features of
tai chi exercise have been published. Objective: To analyse the
kinematics and electromyographic characteristics of tai chi.
Methods: An experienced tai chi master was asked to perform a
sequence of basic movements: ward off, roll back, press, and
push. The movements were videotaped and digitised using a motion
analysis system. Electromyographic activities of the lumbar
erector spinae, rectus femoris, medial hamstrings, and medial
head of gastrocnemius were recorded by surface electrodes. The
push movement data were analysed. Results
