[Purpose] We assessed the clinical application of the setting pressure, which was determined with a mercury sphygmomanometer, as an indication for the quantitative evaluation of the isometric muscular contractile force on the quadriceps femoris muscle setting exercise. [Subjects] The subjects were the 24 legs of 24 healthy persons (with a mean age of 20.3 years) which they used to kick a ball. [Methods] We determined the isometric muscular contractile force (the setting force: F) in each exercise by setting a target level of increasing the varnishing pressure in the popliteal region (the setting pressure: P) at intervals of 10 mmHg. The knee extension moment (M) and the setting force [Ffair (Ff)] on exertion of muscle strength by the quadriceps femoris MMT3 (fair) were calculated according to a formula. [Results] There was a highly positive correlation between F and P (F = 0.716P + 1.034). There was also a highly positive correlation between Ff and M (Ff = 1.959M + 5.699). [Conclusions] The setting pressure reflected the isometric muscular contractile force. It was also possible to evaluate the muscle strength of the quadriceps femoris MMT3 from the setting pressure.
