It is provided an apparatus for training a person's lower and/or upper extremities, comprising at least two motion elements which are arranged on a base element, wherein the motion elements each have an axis of rotation around which an actuating element can be moved. The motion elements each are independently movable relative to the base element about a first axis of movement, wherein the first axis of movement extends substantially perpendicular to an extension surface of the base element. Each motion element has a separate drive in order to rotate the actuating elements about the axis of rotation, and that the apparatus includes a control element which can individually actuate each drive in order to provide for a movement of each drive independent of a movement of another drive.

Provided herein are devices and methods for analysis and/or exercise of a body region of a subject. Such devices may include a guide arm supported by a support frame; a receiving surface supported by the guide arm, the receiving surface for receiving input force from the subject; and a motor assembly in communication with the guide arm, the motor assembly controlling movement of the receiving surface based on received input force. Exercise and/or analysis methods described herein may include steps of instructing the subject to apply an input force to a receiving surface; sensing the applied input force over time; and controlling movement of the receiving surface based on the received input force using a motor assembly, whereby the motor assembly moves the receiving surface in a pre-determined direction, so long as the input force remains within an allowable tolerance, until a pre-set end position is reached.

A shooting system includes a collapsible ball capture support adapted to support a ball capture device and a ball return. The ball return detects a ball captured by the ball capture device and returns the ball to a user in response to the detected ball. To return the ball to the user, the system identifies a location of the user with respect to the shooting system, orients the ball return toward the user, and accelerates the ball along a trajectory based on a distance between the user and the shooting system.

Systems and methods of analyzing a user's motion during a swimming session are described. One or more motions sensors can collect motion data of the user. A processor circuit can make motion analysis based on the motion data. The processor circuit can determine if the user's arm swing is a genuine swim stroke. The processor circuit can also determine whether the user is swimming or turning. The processor circuit can also classify the user's swim stroke style. The processor circuit can also determine the user's swim stroke phase. The processor circuit can also determine the user's stroke orbit consistency.

Exosuit systems and methods according to various embodiments are described herein. The exosuit system can be a suit that is worn by a wearer on the outside of his or her body. It may be worn under the wearer's normal clothing, over their clothing, between layers of clothing, or may be the wearer's primary clothing itself. The exosuit may be assistive, as it physically assists the wearer in performing particular activities, or can provide other functionality such as communication to the wearer through physical expressions to the body, engagement of the environment, or capturing of information from the wearer.

A training, rehabilitation, and recovery system comprises an exercise apparatus including a user interface member coupled to a plurality of links and joints, brakes capable of resisting movement of at least a subset of the links or joints, and sensors capable of sensing movement at the joints or the user interface member. The system also includes a processor configured to receive from the sensors positional data of the links or joints over an initial movement of the apparatus by a user, from which positional coordinates of the user interface member are calculated and a reference trajectory is established. An end space is defined based on the reference trajectory. Over a subsequent movement of the apparatus by the user, the processor receives additional positional data and determines a completion of a repetition based on the positional coordinates of the subsequent movement and the defined end space.

An exercise feedback system monitors the performance of athletes wearing a garment with sensors while exercising. The sensors generate physiological data such as muscle activation data, heart rate data, or data describing the athlete's movement. The system extracts features from the physiological data and compares the features with reference exercise data to determine metrics of performance and biofeedback. Based on the physiological data, the system may also modify exercise training programs for the athlete. The exercise feedback system can display the biofeedback using visuals or audio, as well as modified exercise training programs, via the athlete's client device in real time while the athlete is exercising. By reviewing the biofeedback, the athlete may correct the athlete's exercise form to properly use the target muscles for the exercise, or change the certain workouts to personalize the training program.

Attachments for isokinetic dynamometers and methods of use thereof are provided for use with subjects having limb impairments. An example dynamometer attachment for use with a subject having an impaired limb includes a frame that has fixed thereto a padded limb support, where the padded limb support is configured to secure an impaired limb of the subject. The padded limb support includes a securing mechanism for securing the impaired limb relative to the frame, and the frame is connected to the dynamometer lever arm via an intermediate connector assembly. The connector assembly permits translation of the padded limb support in at least two dimensions relative to the lever arm prior to securing the frame fixedly in place. The translation adjustability of the attachment facilitates the alignment of the dynamometer attachment to the limb or partial limb of the subject without requiring movement of the subject.

An auxiliary drive for a training device, comprising a first force measuring device, a control device, and a drive unit, wherein the control device determines a target force F.sub.S,max, the first force measuring device determines an actual force F.sub.S which is applied to a main traction means and which is caused by an acceleration of a movable mass connected to the main traction means. The first force measuring device also transmits the determined actual force F.sub.S to the control device, and the control device also compares the actual force F.sub.S with the target force F.sub.S,max and controls the drive unit such that, if the actual force F.sub.S exceeds the target force F.sub.S,max, an auxiliary force F.sub.Z having a component that offers resistance to a gravitational acceleration acts on the movable mass by connection of the drive unit to the movable mass.

A system and methods of fitting golf clubs, and more particularly, the systems and methods related to wedge type golf clubs, having multiple sole configurations and/or bounce angles. More specifically, the present invention is directed to system and methods that enable a player to quantify the performance of the golf club's sole interaction with the ground and to determine the sole configuration and bounce angle that provides the most optimal shot performance.
