A physical exercise apparatus includes a frame equipped with a crankset and a saddle. The saddle includes a chassis fastened to the frame, two saddle parts, and articulation members for articulating each saddle part relative to the frame around a pitch axis, a roll axis, and a yaw axis. The apparatus includes sensors for detecting a pitch movement, a roll movement, and a yaw movement of each saddle part respectively about the pitch, roll, and yaw axes, these movements resulting from pedaling made by a user. At least one calculation unit determines, from output signals of the sensors, angular amplitudes of the pitch, roll, and yaw movements. At least one screen is provided in order to display, depending on the angular amplitudes determined by the calculation unit, the position on each saddle part of a bearing point of an ischium of a user in the process of pedaling.

A method of calibrating a crank arm-mounted power meter includes receiving an angle measurement from a first sensor disposed on a crank arm, the angle measurement corresponding to an angular orientation of the crank arm. A predicted load measurement is then calculated based on the angle measurement and weight data for the crank assembly including the crank arm and stored in memory. A load measurement corresponding to a load on the crank arm is obtained and a zero offset value is then calculated by determining a difference between the predicted load measurement and the load measurement. Power calculation logic for determining power applied to the crank arm is then updated using the zero offset value.

A stationary bike capable of leaning of tilting side to side during use is described. The stationary bike has a fixed frame portion and moving frame portion which is pivotally mounted on the fixed frame portion, at two spaced apart pivot locations, to allow the moving frame to pivot about a pivot axis defined by the two spaced apart pivot locations. The pivotal action of the bike may be resisted, such as by a damper. The tilt-enabled bike is equipped with a tilt disabling mechanism, e.g., a locking mechanism configured to selectively and operatively engage the moving and the fixed frame to disable the relative movement (i.e. the pivoting) of the moving frame.

An ergometer according to this invention comprises pedals rotated by an exerciser, a motor connected to the pedals, and a control device connected to the motor in order to control an operation of the motor, wherein a control mode of the control device for controlling the motor can be switched between a concentric contraction exercise mode, in which the motor is caused to function as a load while the pedals are rotated by the exerciser, and an eccentric contraction exercise mode, in which the motor rotates the pedals so that the exerciser is forced to resist the rotation of the pedals.

A stationary exercise device with a driving assembly with a driving wheel rotating around a driving axle, a first and a second crank each connected to the driving wheel and two pedals, each connected to one of the cranks, a flywheel connected to the driving assembly by at least one gear mechanism, a brake assembly for applying a braking force to the flywheel, at least one measuring device for measuring the position of the first and second crank is provided. A detection device detects several time intervals, in each of which the flywheel is displaced a predetermined angle, the detection device further detects time differences between at least two of the time intervals. A control device determines, through dependence of the time differences between at least two of the time intervals, a torque at the driving wheel or a value dependent on the torque at the driving wheel.

A system for rehabilitation is disclosed. The system for rehabilitation includes one or more electronic devices comprising one or more memory devices storing instructions, one or more network interface cards, and one or more sensors, wherein the one or more electronic devices are coupled to a user. The system for rehabilitation further includes one or more processing devices operatively coupled to the one or more memory devices, the one or more network interface cards, and the one or more sensors. The one or more processing devices are configured to execute the instructions to receive information from the one or more sensors. The one or more processing devices are further configured to execute the instructions to transmit the information to a computing device controlling an electromechanical device, via the one or more network interface cards.

A pedal assembly for an exercise and rehabilitation device can include a disk having an axis of rotation. A central aperture can be formed in the disk along the axis. Spokes can extend radially from adjacent the central aperture toward a perimeter of the disk. The disk can be formed from a first material. In addition, a crank can be coupled to one of the spokes of the disk. The crank can have a hub concentric with the central aperture. Pedal apertures can extend along a radial length of the crank. The crank can be formed from a metallic material that differs from the first material. A pedal having a spindle can be interchangeably and releasably mounted to the pedal apertures in the crank.

A system includes a treatment device configured to be manipulated by a user while the user performs a treatment plan and a patient interface associated with the treatment device. The system also includes a computing device configured to: receive treatment data pertaining to the user who uses the treatment device to perform the treatment plan; write to an associated memory, for access at a computing device of a healthcare provider, treatment information; communicate with an interface, at the computing device of the healthcare provider; and modify at least one of the at least one aspect and any other aspect of the treatment plan in response to receiving treatment plan input including at least one modification to the at least one of the at least one aspect and any other aspect of the treatment plan.

A pedal exerciser includes a worm shaft meshed with a worm wheel. A crank drives rotation of the worm wheel through two pedals. A rotary disc assembly is journaled to and rotatable with the worm shaft. The rotary disc assembly has a conductive member that is non-magnetizable and that is rotatable around an axis of the worm shaft. A magnetic assembly is disposed near the conductive member and has a magnet facing the conductive member. The magnet produces a drag force to resist an exercising force when the conductive member is rotated to move past the magnet. An adjustment assembly moves the magnetic assembly toward or away from the rotary disc assembly to vary the magnitude of the drag force.
