The point tsu-san-li which is situated below the knee is also known in China as ‘three villages’. A regular pressure on this point increases the strength of knees and feet. It is believed in China that one who takes the help of this point can walk much more (the distance between three villages) than ordinary persons. The heart of an athlete is put to considerable strain. This is prevented by treating the acupressure point called nei-kuan situated near the wrist, which helps to regulate blood circulation and breathing.  Dr. Zier of ‘Damp 2000’, a well-known hospital in Germany is carrying out trials with acupressure.  He has measured the performance of athletes on a static bicycle before and after the stimulation of acupressure points. He says that acupressure increases strength and checks an improper increase in the heart rate after strenuous activities.  Acupressure also has a very good effect on muscular pain and cramps.
