A system for rehabilitation includes an electronic device comprising a memory device for storing instructions, a network interface card, and a sensor. The system for rehabilitation further includes a processing device operatively coupled to the memory device, the network interface card, and the sensor. The processing device is configured to execute the instructions to determine a plurality of angles, wherein the plurality of angles comprises at least one of the following: angles of extension of a first body part of a user extended away from a second body part of the user at a joint, and angles of bend of the first body part retracting closer toward the second body part. The processing device is further configured to execute the instructions to transmit the plurality of angles to a computing device controlling an electromechanical device, via the network interface card.

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.

A training apparatus having a progress indicator and unified base for different apparatus types, such as for an ergometer, speed bike, recumbent bike, home training bike, rowing apparatus, elliptical trainer, cross-trainer or treadmill. The fitness apparatus of every apparatus type is based on a structure which is unified in terms of technical design, according to which the frame or pedestal of the fitness apparatus has rollers which are arranged on the frame or pedestal such that a tilt-stable positioning of the frame with respect to the subsurface and a longitudinal displacement of the frame or of the frame together with the pedestal relative to the subsurface is enabled by means of an actuator depending on the measure of success of the user training.

A training device includes a force receiving component, a location detector, a resistance generator, and a controller. The force receiving component moves along a closed trajectory. The location detector is configured to detect a location of the force receiving component in the closed trajectory and to output a location signal. The resistance generator is configured to exert a resistance on the force receiving component. The controller controls the resistance generator to adjust the resistance based on the location signal.

A push-up exercise enhancement device for verifying and counting push-ups includes a base. Each of a pair of rods is coupled to and extends perpendicularly from proximate to a respective opposing end of the base. Each rod comprises a plurality of nested sections so that the rods are selectively extensible. A plate is coupled to and extends between the rods distal from the base. The plate and the base define an upper limit and a lower limit for a proper push-up. A counter is operationally coupled to the base and the plate. The counter is configured to assess sequential contacts to the base and the plate by the torso of the user to determine the proper push-up and to display a count of the proper push-ups to the user.

This method creates a safer exercise environment with a modern technology that does not alter the tradition of mechanical training, yet provides the gymnasium machines with this intelligent system to prevent injuries. The approach is to equip the exercise machines with a way of analyzing its user performance as long as he works out, by the continual collection of data from various sensors after the user personalized the gymnasium equipment, these data are used as a basis for servo system to give the appropriate set of instructions through some written programs to guide the step motor and the piezoelectric bore to control that exercise equipment in order to prevent said accidents whenever there is said sudden failure from the user's muscle.

A resistance force is controlled such that a user's effort against the resistance force results in a first isokinetic seed movement. The resistance force required to effect the first isokinetic seed movement is associated with a force-velocity profile. It is determined whether a sufficient number of isokinetic seed movements have been performed by the user. In response to a determination that the sufficient number of isokinetic seed movements have been performed by the user, a strength determination of the user is made based on the isokinetic seed movements performed by the user.
