It is the object of the present invention to provide a mobile platform that allows the execution of physical stimulation and rehabilitation exercises through augmented reality games, of simple preparation and configuration, adaptable to various spaces and operating conditions. For this purpose, the platform comprises a sensory unit (2) and a projection unit (5), which are controlled by a processing unit (4). All these units are integrated in a mobile base (9), to allow the displacement of the platform. This also comprises a rotating joint (7) and an articulated arm (8) to allow the projection of games on the floor or on the wall.

A muscular integral development system for resistance (MIDSYR) to develop or exercise muscles of a body of an user. The system is directed to develop an area of the body or specific muscle group, such as for example the abdominals, pectorals, biceps, buttocks or leg muscles. Furthermore, the present invention relates to an equipment to achieve weight loss, cardiovascular exercise or rehabilitation.

A training apparatus including a training element for a user performing exercises, an AC motor and a frequency converter being arranged to control the AC motor, wherein the frequency converter comprises measuring means being arranged to measure a voltage and a current of the AC motor and calculation means being arranged to calculate a magnetic state of the AC motor using the measured voltage, the measured current, a reference torque and a reference flux in order to generate a torque of the AC motor. The training apparatus further comprises a control unit having a machine control module being arranged to calculate the reference flux and the reference torque using an intended overall torque, wherein the machine control module is connected to the frequency converter and arranged to transmit the reference flux and the reference torque to the frequency converter.

The exercise machine with a variable resistance system includes a frame, an exercise implement movably connected to the frame, a main shaft rotatably connected to the frame, a main connector attached between the main shaft and the exercise implement, a plurality of resistance assemblies and a plurality of actuation assemblies adapted for selectively engaging or disengaging at least one of the plurality of resistance assemblies with respect to the main shaft. The plurality of resistance assemblies apply a total level of rotational resistance against the main shaft based on which of the plurality of resistance assemblies are engaged with the main shaft by the plurality of actuation assemblies.

An elliptical system is disclosed having a crank assembly configured to be adjusted in length to accommodate users having varying gaits. In some embodiments, the crank assembly includes a crank and an axle connection bracket that is slidably adjustable with respect to the crank. For example, the crank assembly can include a crank link having a longitudinal body, where the longitudinal body is connected to the crank at one end and includes a longitudinal slot slidably coupled with the axle connection bracket. The axle connection bracket is configured to slide through a plurality of positions along the longitudinal body. In some embodiments, the crank assembly further includes a screw for adjusting the axle connection bracket with respect to the crank, where the screw can cause the axle connection bracket to slide through one or more positions of the plurality of positions when the screw is turned.

An exercise device comprises a motor, a boxing accessory, and a cable coupled between the boxing accessory and the motor. In one embodiment, a sensor is configured to determine telemetry data associated with at least one of the motor or the cable, wherein the telemetry data comprises at least one of the following: cable acceleration, cable velocity, and cable position. In one embodiment, an arm is coupled to the cable and the arm is configured to position the cable.

An apparatus for resistance training comprising a frame supporting: a rotational pivot for providing rotation in a vertical plane; a horizontal reaction arm adapted to be moved by a human user; and an actuation arm rotatably mounted on the rotational pivot and rotationally mounted on the horizontal reaction arm; such that a force on the horizontal reaction arm causes the reaction arm to move about the rotational pivot whilst remaining horizontal. The frame further comprises a resistance means arranged to apply a user-selected resistive force that must be overcome to induce movement of the horizontal reaction arm from a rest position. The actuation arm has a length that is adjustable by the human user. The rotational pivot is vertically moveable within the frame. The horizontal reaction arm is capable of being moved in both a clockwise or anti-clockwise sense about the rotational pivot.

Embodiments allow the application of a settable and/or a programmable resistance to a trainee's leg Drive Phase and/or Recovery Phase while walking or running over extended or infinite distances. Multiple mechanical or electrical feedback loops or combinations of both to monitor the applied resistance to the Trainee by the tether or tethers and then control the amount of breaking (drag) or propulsion created by the Mobile training module during the acceleration and constant speed training phases to accurately generate, control and transfer resistance through the elastic tethers to the Trainee. Embodiments apply multiple, non-varying loads or programmable loads to multiple body parts of a trainee where applied resistance can be manipulated to both increase or decrease over distance as desired by trainee while the trainee is walking, running or sprinting over any distance.

The subject matter of the invention relates to a method and system for energy absorption designed for use in particular in exercise apparatuses, and especially in the so-called fitness equipment.

The method for energy absorption consisting in that suitable current load values are selected in order to balance the kinetic energy expended by the person performing exercises with the energy absorbed by the system (100) for energy absorption, wherein the value of current load, which is selected by a computer (PC), is dependent on the psychomotor parameters of the person performing exercises.

The system (100) for energy absorption is provided with a variable current load circuit (150) connected to an element (S) producing direct current (DC) or alternating current (AC) electric energy, which is controlled by the computer (PC). The system (100) is also provided with a real-time counting/positioning circuit (120) incorporated between the element (S) producing direct current (DC) or alternating current (AC) electric energy and/or a mechanical system (UM), and the computer (PC).
