In one aspect of the disclosure, a motorized Pilates reformer system may include a frame, a carriage configured to slide along the frame, springs attached to the carriage, attachment mechanisms attached to the frame, spring motors attached to the frame, a footbar rotatably attached to the frame, and a footbar motor attached to the frame. The spring motors may be configured to cause the attachment mechanisms to each alternate between attaching one of the springs to the frame and detaching the spring from the frame. The footbar motor may be configured to rotate the footbar with respect to the frame between multiple footbar positions.

A respiratory device of negative pressure type comprising a shell fastened to the user's chest and/or abdomen with minimal dead space, one or more vacuum and compressed air chambers attached to the shell; vacuum generating and compressed air generating sources connected to the vacuum and compressed air chambers respectively, one or more openings on the shell to allow exchange of the air enclosed between shell and user's body, with the vacuum and compressed air chambers; a valve shuttling between the vacuum and compressed air chambers. By having low dead space, pre-generated vacuum and compressed air close to the user, and the use of fast acting valves in some embodiments, the power requirement, weight, and size are reduced, making the device low cost and portable. In some embodiments, the vacuum and compressed air generating sources can be mounted on the shell itself, making the device ambulatory.

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.

One or more apparatuses are provided. In an example, an exercise machine is provided. The exercise machine may include one or more driving elements connected to one or more motors controlled by a computer. The one or more motors may be configured to provide an electromechanical resistance via the one or more driving elements. The electromechanical resistance may be controlled by smart algorithms running on the computer such that variable resistance is provided at different parts of movement. The algorithms may use readings from one or more sensors. The exercise machine may include a controller configured to control the motor based upon one or more inputs. The exercise machine may include an exercise bar. The exercise machine may include a screen. The exercise machine may include safety actuators. The exercise machine may be fixed on its place or may be portable. The exercise machine may include electromechanical safety stand(s).

Described herein is a breath training apparatus [100], comprising a breathing unit [102], a CO.sub.2 modulation unit [106, 108], and a control unit [112]. The breathing unit [102] has an enrichment airflow pathway [102c], and is adapted to provide inhalation air with enriched CO.sub.2 concentration. The control unit [112] comprises a CO.sub.2 actuator [112a, 112b], a CO.sub.2 sensor [112d], and a controller [112g]. The controller: receives the signals corresponding to CO.sub.2 concentration within the enrichment airflow pathway [102c] from the CO.sub.2 sensor [112d], compares the CO.sub.2 concentration with a defined CO.sub.2 concentration; and correspondingly controls the CO.sub.2 actuator [112a, 112b] for controlled manipulation of the CO.sub.2 modulation unit [106, 108], such that the controlled manipulation of the at least one CO.sub.2 modulation unit [106, 108] adjust the CO.sub.2 concentration within the enrichment airflow pathway [102c] at least substantially equivalent to the defined CO.sub.2 concentration.
