Abstract
ECGs analysis was done for a qi-receiver during Toh-ate (remote action; an ancient Japanese martial art) with double blind. Two practitioners were isolated in two rooms under the condition of cutting normal information transfer. One practitioner (sender) sent qi randomly once per trial of 80 seconds and the other (receiver) tried to perceive the qi; at the time he perceived it, he pushed a switch. Their sending times, receiving times and physiological data were recorded during the experiments. The receiver's ECG RR intervals were measured, and their fluctuations before and after the sending times were analyzed. As a result, in a group of trials without the receiver's switch signals, the coefficient of variation of RR intervals for 10 seconds after the sending times was larger by a statistically significant amount (1%) than before them.
