Abstract
The water pletysmograph for the forearm, with electric recording apparatus, including an ergometer, was devised and presented. The collecting pressure applied to the arm was ascertained and the pressure lower than the dyastolic pressure by 5-10mmHg, applied for 5〜10 seconds, was found to be adequate to record the blood inflow to the tissue. By means of this method, it was demonstrated that the forearm blood flow was increased after exercise of maximum efforts exerted every two seconds, and the increase of blood flow was related to the number of maximum contractions, but it seemed to reach a plateau after certain contractions. Remarkable increase of blood flow was also found after exercise with the load of one-third of maximum strength to exhaustion. Among subjects, a large difference of blood flow was found after both kinds of exercise.
