Development of a Bilateral Split Saddle to Measure Reaction Force for Cycling Motion Analysis

Abstract

In cycling motion analysis, a reaction force applying to each of the thigh from a saddle should be measured to calculate the hip joint torque. For this, a saddle type sensor that is split bilaterally has been developed in this study. This sensor measures a loading point in the error of 2 mm at most. From the measurement of a pedaling motion, the path of contact point between the sensor and the thigh was observed in lateral edge of the saddle surface. This result could not be obtained from a non-split saddle sensor, and the bilateral split sensor should be useful to analyze the pedaling performance kinetically.
