Provided is an apparatus for managing a player with a guard including a sensor sensing a vital information of a player to calculate an injury risk of the player to thereby manage a condition of the player, the apparatus including: a communication unit receiving the vital information from the guard and transmitting the injury risk to the guard; a memory storing a program calculating the injury risk to manage the condition of the player; and a processor connected to the communication unit and the memory to execute an operation implemented by the program, in which the program may include instructions using the vital information and pre-stored vital recovering ability data of the player to calculate the injury risk of the player.

Asymmetrical resistance systems and methods include an asymmetrical flywheel having a braking track disposed on a first side of the flywheel, and a resistance apparatus comprising at least one magnet, wherein a distance between the magnet and the braking track corresponds to a force resisting rotation of the flywheel. The flywheel includes an outer portion comprising a ferromagnetic material, and the resistance apparatus includes a backing plate disposed on a side of the magnets opposite the braking track. A magnetic field flows from a first magnet to the outer portion of the flywheel through the braking track, back through the braking track to the second magnet, and from the second magnet through the backing plate to the first magnet. While the flywheel is rotating, the braking track moves through the magnetic field creating an eddy current that generates a force resistant to the rotation of the asymmetrical flywheel.

Disclosed are biofeedback methods and devices suitable for providing biofeedback useful for helping a user control an own breathing, for example, to help in inducing deep breathing, and such biofeedback devices further comprising a dispenser for dispensing an inhalable substance.

A portable breathing measurement and breathing exercise device includes a body part; a mouthpiece part coupled to one side of the body part; a sensor unit which is provided inside the body part and measures the pressure of a user's breathing via the mouthpiece part; a control unit which receives measurement values from the sensor part and stores the measurement values in real time, analyzes the user's breathing on the basis of the measurement values, and provides an exercise schedule; and a display unit for outputting the analysis results and exercise schedule of the control unit. The mouthpiece part includes a load adjustment unit for regulating the flow rate of air that flows in and out of the mouthpiece part and the body part due to the user's breathing.

When controlling load torque of a drive unit on the basis of a biological signal detected from a subject's lower limb parts, adjustments are made to a hybrid ratio of voluntary control to generate running torque and a rotational speed of a crank according to the subject's intention and autonomous control to generate assisting power for the subject's pedaling motion on the basis of a rotation angle of the crank.

An artificial intelligence-assisted exercise and rehabilitation device includes a frame; at least one mechanical arm, disposed on the frame, a free end of the mechanical arm having an operating part; and an artificial intelligence module, electrically connected to the mechanical arm. The artificial intelligence module automatically identifies a physiological feature of an operator and outputs a control program according to the physiological feature. The control program drives the mechanical arm for the operating part to move along a guidance path. The trajectory of the operator's exercise or rehabilitation exercise can be learned and recorded through artificial intelligence for comparative assessment of the exercise or rehabilitation effectiveness.

System and method for creating an exercise plan for a user based on a goal state of a digital twin of the user. A baseline state of the digital twin is created based on a first 3D model of the user and first physiological data of the user. Using a machine-learning model, an exercise plan for the user, comprising one or more motion profiles, is created that most likely effectuates a goal state of the digital twin from the baseline state of the digital twin. Electronic exercise equipment is configured to physically manifest the one or more motion profiles during exercise activity of the user, and data is acquired by the electronic exercise equipment based on the exercise activity.
