A method for finding a more appropriate pressure that is safer and that does not require anxiety or fear for those who perform the method to increase strength by inhibiting blood flow. provide. The pressure of the air in the gas bag of the pressurizing belt is once increased above the pressure that is regarded as an appropriate pressure, and then the pressure is gradually released. In the process, the pulse wave amplitude is measured, and the maximum pulse wave pressure specifying unit 12E determines the maximum pulse wave pressure that is the pressure of the air in the gas bag when the maximum value of the pulse wave amplitude that rises and falls once occurs. Identify. The maximum pulse wave pressure specifying unit 12E sends maximum pulse wave pressure data indicating the maximum pulse wave pressure to the appropriate pressure calculation unit 12F. The appropriate pressure calculation unit 12F sets the maximum pulse wave pressure multiplied by a coefficient of 0.85 as the appropriate pressure.血流を阻害することによる筋力増強方法における、より安全性が高く、より筋力増強方法を実行する者が不安感や恐怖感を感じなくても良いような、より適切な適正圧を求める方法を提供する。 加圧用ベルトのガス袋内の空気の圧を適正圧と目される圧よりも一旦高め、その後その圧を徐々に抜いていく。その過程で、脈波振幅を測定し、一旦上がりそして下がっていく脈波振幅の最大値が生じたときのガス袋内の空気の圧である最大脈波圧を最大脈波圧特定部１２Ｅが特定する。最大脈波圧特定部１２Ｅは最大脈波圧を示す最大脈波圧データを適正圧演算部１２Ｆに送る。適正圧演算部１２Ｆは、最大脈波圧に０．８５の係数を乗じたものを適正圧とする。
