Another portion of the system includes a first support assembly comprising a first movable cradle configured to receive thighs of the user and a second support assembly. The second support assembly includes a second movable cradle configured to receive a torso of the user, a computing device, and a headrest comprising an opening configured to receive a face of the user such that the user views the computing device. The computing device is configured to receive parameters associated with the user during use of the dry swim simulation system from numerous electrical and/or mechanical components. The computing device is configured to analyze the parameters and provide real-time feedback to the user to improve performance of swimming strokes.

A differential air pressure system has a pressure bag with windows and preferred folding configuration such that when the bag is folded no window is folded. The pressure bag is supported by a lift support that is proximal to a user control panel and adjacent to or nearly adjacent to the user who is coupled to the pressure bag. A treadmill base for use with differential air pressure equipment is provided. There are various improvements provided to adapt the operations of the DAP system via the use of separate pressure volume and non-pressure volume portions of the treadmill base. Various improvements to serviceability and repairs are provided by placement of components outside of the pressure volume portion or by providing one or more pressure volume access points.

Systems and methods for providing a customized exercise protocol to a computing device of a user. As the user performs the exercise protocol, one or more cameras of the computing device can track the user's movements. The user's movement are assessed to determine if proper form and technique is being used.

A method for estimating information on a golf swing is provided. The method includes the steps of: when a photographed image of a user's golf swing is acquired, detecting at least one joint of the user from the photographed image using an artificial neural network model; and estimating information on the user's golf swing with reference to a position of the at least one detected joint.

A method that includes receiving treatment data associated with a user capable of using a treatment device to perform a treatment plan. The method also includes receiving user related data (URD) associated with the use and receiving alignment data associated with the user while the user engages in at least one activity. The method also includes identifying, based on at least the treatment data, the URD, and the alignment data, at least one alignment characteristic associated with the user and modifying at least one aspect of the treatment plan in response to receiving, from a healthcare professional, treatment plan input including at least one modification to the at least one aspect of the treatment plan.

A method for optimizing at least one exercise for a first user. The method includes receiving first user data including attribute data associated with the first user and outcome data associated with the exercise. The method includes generating, based on the first user data, initial target data. The initial target data is associated with at least one of the first user, the exercise apparatus, and the exercise. The method includes receiving measurement data associated with at least one of the first user, the exercise apparatus, and the exercise. The measurement data is associated with one or more sensors. The method includes determining differential data based on one or more differences between the initial target data and the measurement data. The method includes generating, via an artificial intelligence engine and based on the differential data, a machine learning model trained to generate optimized target data.

Disclosed are example embodiments of systems and methods for exercise including an exercise machine including a multiple directional force component configured to apply a multiple directional force to an exercise machine-human body interface, the multiple directional force component further configured to provide a divergent intensity to the exercise machine-human body interface to provide the human body with a resistance during a physical exercise and an artificial intelligence (AI) component configured to control the multiple directional force component. In an example, the AI component may control the multiple directional force component based on morphological characteristics and variability of running speed parameters including at least one of stride length, stride frequency, explosive drive force, and arm drive.

A reciprocating unidirectional electromagnetic resistance device includes a shaft having a flywheel installed to a first end of the shaft, an electromagnetic braking unit, and a first sensing device. A spring return device and a second sensing device are installed at a second end of the shaft, and a pull rope device is installed at the middle of the shaft. The electromagnetic braking unit and the spring return device are integrated into a single module and provided for an operator to perform a reciprocating motion to pull out a pull rope of the pull rope device and drive the shaft, the flywheel and the spring return device synchronously, and the electromagnetic braking unit acts an electromagnetic resistance onto the flywheel, so that the flywheel has the excellent precise resistance of the electromagnetic braking unit. When released, the pull rope can be retracted to achieve the reciprocating motion effect.

A treadmill with an anti-entrapment function allows a user to stand on the treadmill and includes a running unit, a control unit, and a detection unit. The running unit includes two lateral bases, a driving roller, a driven roller, and a running belt. Each lateral base has a bottom end portion lower than the running belt. The detection unit includes a transmitter for emitting a light wave and a receiver for receiving the light wave. When accidently pulled into the gap between the running belt and one of the lateral bases, the user or a foreign object is moved by the running belt to the space between the transmitter and the receiver, thus keeping the receiver from receiving the light wave. The receiver sends out a warning signal in response, in order for the control unit to control the rotation speed of the driving roller accordingly to prevent continued entrapment.

A handheld exercise device is an apparatus that enables the user to exercise the upper body due to the load applied on the user's arms from the centripetal force created by moving the apparatus using one or two hands. To do so, the apparatus may include an O-ring housing, a crossbar, a bearing assembly, and a control system. The O-ring housing is designed to retain the bearing assembly in such a way that the user can move the bearing assembly in a circular motion within the O-ring housing. The crossbar facilitates the handling of the O-ring housing with one or two hands in order for the user to move the bearing assembly in a circular motion within the O-ring housing. The control system helps the user keep track of the movement of the bearing assembly so that the user can measure the exercise progress while handling the apparatus.
