The purpose of this study was to analyze the mechanical energy contribution of the lower extremity joint to sprint start according to the changes of inclined angle of starting block(F, F1, F2). Using kinetic and kinematic data from 3 university sprinters participating in this study we calculated the energies absorbed and generated by the lower extremity joints.Comparing mean of the energy absorbed and generated from lower extremity joints of each subjects according to backward block inclined angle increase(F, F1, F2) we generated ratio of a total energy absorbed and generated from lower extremities to one from knee joints. Generated energy of knee joints in start was highest and absorbed energy of ones was the lowest at 55 degree of backward block angle, or F, for subject 1, 50 degree for subject 2, and 50 degree for subject 3.
