Blood in lower position is said to be pumped up to a heat by calf muscle. So stretching of an Achilles' tendon is good for our health. Stretching is quite easy for a healthy person, but it is not easy for either the aged or a disabled person. Accordingly the hamstring stretching equipment was developed and evaluated. As the results of this research, the blood flow rate was closely related to the pedal angle of stretching equipment. Through our research, it was concluded that varying the pedal angle was recommended for the sake of increasing blood flow rate. The change of blood flow rate was not observed in stretching goods on the market.
