Abstract - Experimental study of “Shin- Poh”. Judoka’s way of feeling
At Mount Kinpo (2599 m, Nagano, Japan) we measured an autonomic nerve of a judo-ka. We used a small electrocardiograph with an active tracer (AC301A,GMS. Co. Ltd., Japan) for an experiment. We measured a sympathetic and a parasympathetic stimulation in the body while the judo-ka was climbing up to the top of the mountain. We found the characteristics of the judo-ka from the data including sympathetic and the parasympathetic nerve reaction after climbing the mountain.
Spectrum analysis was based on electrocardiogram and the high (HF) and low frequency (LF) power high frequency power (LF/ HF) evaluated using an active tracer (AC301A,GMS. Co. Ltd., Japan) [Hosonuma, Asano 2010].
