Patent ID: 7608015

Claim:
A method of controlling stationary exercise apparatus of the type having at least one movable component providing a simulation of a corresponding physical activity involving human motion, wherein the exercise apparatus is capable of controlling at least one of the movement and the resistance of the movable component to simulate the effects of changes in momentum that occur during the physical activity, the method comprising: determining an equation of motion for a physical activity involving human motion that is to be simulated by the exercise apparatus, wherein the equation of motion includes at least one term that accounts for changes in momentum and a corresponding force experienced by a human during the physical activity; determining a value of a variable corresponding to at least one of a user's mass, a velocity of the movable component of the exercise apparatus, and a force applied to a component of the exercise apparatus during use thereof; providing a controller; configuring the controller to control at least one of the movement and the resistance to movement of the at least one movable component to simulate the effects of changes in momentum based, at least in part, on a control parameter determined at least in part by the value of the variable and the equation of motion for the physical activity being simulated by the apparatus.
