[Purpose] The purpose of this study was to examine the effect of knee joint position on foot-gripping strength. [Subjects and Methods] The study included 14 healthy females. We measured the foot-gripping strength and maximum voluntary contraction activities of the rectus femoris muscles, and the biceps femoris muscles, andcalculatedduring foot gripping in the following 2 knee joint positions: 90°of flexion, and extension, for a subject positioned on the edge of a seat. [Results] A paired t-test showed that the footgripping strength and %IEMG of the biceps femoris muscle was significantly lower in knee extension compared to that in 90°of knee flexion. [Conclusion] The results of this study suggested that the knee extension position did not produce maximum foot-gripping strength.
