Abstract

The purposes of this study were to suggest and validate a new hopping viscoelastic model which can consider the differences of the characteristics of lower extremities and the time lag of the landing between both extremities. Six healthy male subjects performed fixed rhythm hoppings to measure impact forces. A new viscoelastic model which has two contact points was established. The equation of motion was derived from this model. The parameters of the model were determined by optimization using an objective function which includes a measured vertical ground reaction force. The same procedure was done using an old viscoelastic model which has only one contact point to compare the simulated results. The results showed that the new model could consider the difference between both feet and simulate both vertical ground reaction force during hopping.
