An indoor, stationary, bicycle training device that provides advantages over conventional designs of exercise bicycles is provided. The stationary bicycle may include a tilting/pivoting mechanism to orient the indoor bicycle to simulate descending or climbing. The indoor bicycle may include flexible and resilient frame elements to support the indoor training device to move side-to-side under some riding situations thereby simulating the side-to-side swaying motion of an outdoor bicycle under the same riding situations. The indoor bicycle may include several combinations of frame adjustments to provide configurable dimensions of the indoor bicycle to adjust the frame to properly fit the rider, which may be adjusted based on corresponding dimensions of a user's outdoor bicycle. Still other aspects of the stationary bicycle device may aid in creating an “outdoor” feeling while using the device.

An actuator and an exercise equipment using the same are disclosed. The exercise equipment comprises a post which is a main body of the exercise equipment, a shoulder installed on an upper side of the post and rotates in left and right direction, an arm combined with the shoulder and rotates in up and down direction, a hand combined with one terminal of the arm and rotates by using the arm as an axis, a handle located on one terminal side of the hand, a force control actuator outputs a force corresponding to weight set by a user, and a wire passes via plural sheaves included in the hand, the shoulder and the post and deliver a force generated by pulling of the handle, one terminal of the wire being connected to the handle.

The disclosure teaches a novel exercise apparatus. This apparatus does not generate load momentum. The apparatus is based around a series elastic torque sensor and contains an intelligent servo drive with reduction gear to control a variable speed rotating motor shaft. The combination of the motor, gear reducer, spring, angle measurement sensors (position sensors), and intelligent motor controller is a series elastic actuator which is the basis for the exercise device. The exercise device also contains a load transfer mechanism adopted to provide an interface between an individual and the torque sensor. The apparatus allows for isokinetic, isometric, isotonic, and variable force modes of exercise without hardware configuration.

An exercise machine may include a reciprocating linkage that supports one or more pedals configured to move in a closed loop (e.g., elliptical) path as a user exercises with the machine. The exercise machine may be adjustable to vary a characteristic of the exercise provided by the machine, for example by changing an incline of a rail supporting the reciprocating linkage, and thus an angle of the closed loop path. The exercise machine may vary the incline with a lift mechanism operatively associated with the front upright frame of the machine, which may also support a resistance assembly, all in a compact form factor that may be more aesthetically pleasing and practical for relatively smaller exercise spaces.

Methods and systems for controlling a force generator of an exercise apparatus are described wherein the method comprises determining or receiving angular positions of a rotatable axle of an exercise apparatus when a force is applied to a force receiving structure of the exercise apparatus, the rotatable axle being part of a mechanical power transmission system connecting the force receiving structure via the rotatable axis to a force generator which is controlled by a computer based on a kinematic model, the kinetic model representing equations of motion of the exercise the apparatus; determining or retrieving first geometrical scaling values associated with the angular positions and incorporating the first geometrical scaling values into the kinematic model to form a first modified kinematic model, the first geometrical scaling values being associated with a non- circular gear of a first predetermined non-circular geometry; and, determining applied force values for the angular positions, each applied force value representing a force that is applied to the force receiving structure; and, controlling the force generator based on first resistive force values to mimic an exercise apparatus comprising a mechanical power transmission system including the first non-circular gear, the first resistive force values being computed using the first modified kinematic model and the applied force values.

The apparatus additionally includes a mechanical lever arm structure or another mechanical connecting structure, which is for a user's limb contact and which is at a second end connected to the pneumatic resistor element. The apparatus additionally includes a sensor structure, a calculation arrangement and a display. The sensor structure is arranged to measure at least one measurement quantity of the exercise task and, based on the measurement, the calculation arrangement is arranged to form information on the display of the apparatus, regarding the power and/or force and/or range of motion of the exercise task. In the invention, regardless of the number of pneumatic resistor elements, the sensor structure includes one pressure sensor only, and to compensate for the small number of sensors, the calculation arrangement includes a correlation-taught calculation unit, which comprises a correlation algorithm taught with a larger number of sensors than the number of sensors in the apparatus, concerning the correlation between power and/or force and/or range of motion of the exercise task and the measured information.

An exercise apparatus and method for applying one or more lateral resistive loads to drive, swing and other phases to participants while performing complex motions at low or high speeds to condition one's body to better and more quickly perform physical movements at high speeds. Elastic members may be used to generate resistance emanating from a ground-based or vertically-positioned apparatus. The elastic members may connect to one or more body parts simultaneously. The apparatus may be mechanically designed to fully retract the elastic members into the apparatus to maintain resistance while participants are in close proximity to the apparatus. The apparatus provides a plurality of self-contained elastic members and provides participants the ability to alter the vertical and horizontal positions of each elastic member's emanation point from the apparatus. This provides ability to control applied resistance vectors between the attachment point on the participant and the apparatus.

An interactive exercise system with apparatus and methods to optimize muscle strength for rehabilitation, to improve or maintain fitness, and to enhance the performance of athletes. The system uses an electronically controlled linear actuator to generate resistance against the muscular force exerted by the user. The system includes sensors configured to detect acceleration, speed, velocity, position, direction of movement, duration, and the force applied by the user. A control system preferably continuously monitors the sensors, and instantaneously adjusts the adaptive actuator. This provides a proportional counterforce to the user force throughout the entire range-of-motion. A display panel allows the user to interact with the system in real-time. The objective of the user is to synchronize the exercise performance with a selected target goal, by correlating the user's movement relative to a position on a display panel.

A resistive therapeutic device is disclosed such that upon a user applying torque a controller emits a signal to an electromagnetic resistance generating member. The controller detects a maximum torque applied by a user detects if the maximum torque applied by a user is less than or equal to a resistance setting. The torque resistance is variable from a neutral position to a maximum position, and the controller increases the resistance setting as a user moves a torque application member in a direction away from the neutral position that represents an increase in torque applied by the user. A control and user interface for a resistive therapeutic device includes an evaluation display of torque strength applied and displays an angle of rotation clockwise or counterclockwise directions ranging from 0 degrees to 360 degrees and a count of repetitive times a user has rotated at least 360 degrees in either direction.
