An exercise and performance evaluation apparatus includes a revolving belt on which a subject can perform bipedal locomotion, a harness for securing the subject at a fixed position relative to the apparatus, a means for measuring the force applied by the subject to the belt, and a means for monitoring and controlling the velocity of the belt. The harnessing of the subject allows monitoring of the velocity as a function of time. An overhead harness may be used to alter the effective mass of the subject. The velocity of the belt may be controlled by a motor and brake system, where the motor may be uni-directional or bi-directional. A digital processor may be used to control the motor and/or brake as a function of the applied forces to simulate real-world or virtual world environments, allowing the operation of the device in modes such as constant-force modes, constant-load modes, constant velocity modes, sprint simulation mode, bob sled simulation mode, terminal velocity determination mode, isokinetic overspeed mode, and isotonic overspeed mode. Processing of the velocity and force as a function of time allows for the recording and analysis of data such as the maximal exertion force-velocity curve, left leg/right leg performance, force as a function of stride, etc.

What is claimed is: 1. 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. 2. The method of claim 1, wherein: the equation of motion includes a term corresponding to an incline angle of a hill involved in the physical activity being simulated; and the controller utilizes the incline angle to control the at least one movable component. 3. The method of claim 2, wherein: the equation of motion is for a physical activity that includes bipedal locomotion; the movable component comprises a conveyor; and the controller controls at least the velocity of the conveyor. 4. The method of claim 1, including: utilizing the equation of motion to determine a corresponding haptic equation including a measured velocity and an update velocity; and controlling the movable component based, at least in part, on the update velocity. 5. The method of claim 1, wherein: the controller utilizes a force generated by a user to control the resistance to movement of the movable component. 6. The method of claim 5, wherein: the force generated by a user acts on a component of the exercise apparatus other than the movable component. 7. The method of claim 1, wherein: the controller utilizes the velocity of the movable component to control the resistance to movement of the movable component. 8. The method of claim 1, wherein: the exercise apparatus includes an electrically-powered motor coupled to the movable component; and the controller is operably connected to the motor; the controller controls the motor. 9. The method of claim 1, wherein: the exercise apparatus includes a brake that varies the resistance to movement of the movable member; and the controller controls the brake. 10. 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 the resistance of the movable component, the method comprising: determining an equation of motion for a physical activity involving human motion that is to be simulated by the exercise apparatus; measuring at least one of a velocity of the movable component of the exercise apparatus during use thereof, and a force applied to a component of the exercise apparatus during use thereof; providing a controller; configuring the controller to control the resistance to movement of the at least one movable component based, at least in part, on the measured velocity or force and the equation of motion for the physical activity being simulated by the apparatus.
