Abstract

To observe various physical indices while doing Taichi-quan, we measured in this paper the pupillary light response and electrodermal activity (for skin conductance level; SCL) in a beginner and an experienced person who has trained for 20 years. In the experiments, pupillary light response and SCL were shown to change diametrically to each other. As each of those two indices is known to be related to autonomic nerve actions, the results might suggest differences of autonomic stimulation or acceptance/response at the target tissue (such as regional differentiation of sympathetic efferents) among various organs or tissues.
