It was immediately reprinted.

I think the content is substantial.

Although many books on autonomic nerves have been published, they are also used in the U.S. Department of Defense and space development. We actually measured using HRS and explained it in the document.

This system measures and teaches many world-class athletes such as gold medalists, F1 racing drivers who have won overall, major leaguers, world champions in professional boxing, and annual champions in professional golf tours.

Using this system, I created a doctoral dissertation (third author is the director of the Daichi Suzuki Sports Agency) in the doctoral program at Juntendo University School of Medicine.
