太極拳実施による瞳孔対光反応及びEDAの変化(第29回生命情報科学シンポジウム) Changes of Pupillary Light Response and Electrodermal Activity (EDA) while doing Tai chi-Quan(The 29th Symposium on Life Information Science)

太極拳実施に伴う各種生理指標の観察において、今回は初心者と鍛錬歴20年の熟練者との2名の協力者により、瞳孔対光反応と皮膚電気伝導度(SCL)を測定した。本実験から瞳孔対光反応とSCLとは各々相反する動きが観察された。これら二つの指標はいずれも自律神経活動との関連が知られており、その発現様態の相違(不均一な地域性反応など)が示唆された。

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.
