A: Spring-mass model for hopping. This model consists of a body mass and a massless linear spring supporting the body mass. The model is shown at the beginning of the ground contact phase (left), the middle of ground contact phase (middle), and at the end of ground contact phase (right). B: Comparison of Kleg among brace conditions in three hopping frequencies.
