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.

Described herein are systems and methods of guiding a user to achieve musculoskeletal counterpulsation. A method may include receiving a cardiovascular cycle signal from a first sensor; determining a heart rate of the user based on the cardiovascular cycle signal; receiving a rhythmic musculoskeletal activity timing signal from a second sensor; determining an actual musculoskeletal activity cycle (MSKC) to cardiovascular cycle (CC) timing relationship; comparing the actual MSKC to CC timing relationship to a target MSKC to CC timing relationship; providing a recurrent prompt to the user as a timing indication for performance of a rhythmic musculoskeletal activity to guide the user to achieve a musculoskeletal activity cycle rate (MSKR) that approaches the target MSKC to CC timing relationship; and altering a feature of the recurrent prompt based on a determined alignment between the actual MSKC to CC timing relationship and the target MSKC to CC timing relationship.

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.

A treadmill includes a frame and a running belt coupled to the frame. The running belt is configured to rotate relative to the frame. The treadmill includes a controller coupled to the frame, and at least one sensor coupled to the controller. The at least one sensor is configured to collect information regarding a rotation of the running belt and a use of the treadmill by a user including a cadence, a ground contact time, and a stride length of the user of the treadmill. The treadmill further includes a display device coupled to the frame. The display device is configured to display the collected information regarding the rotation of the running belt, the cadence, the ground contact time, and the stride length of the user of the treadmill. At least one light source is configured to selectively emit a light regarding the treadmill.

A treadmill includes a frame; a running belt configured to move relative the frame; and a motor coupled to the running belt. The motor is operable in a plurality of user controlled operating modes. In a first operating mode, the force of rotation of the running belt is provided by a user of the treadmill. In a second operating mode, the motor applies a desired braking force to resist rotation of the running belt. In a third operating mode, the motor applies a torque output to the running belt based on a force exerted on the running belt by a user of the treadmill.

An exercise system. A member ID of a member of the exercise system is received. A selection of an exercise routine comprising of two or more exercises is received. Settings associated with a previous performance of at least one of the two or more exercises by the member are provided.

A device for performing blood flow restriction training during the day, integrated with a garment, and controllable to apply a desired compression level to a range of muscles with the intent on improving the health and fitness of a user doing normal daily activities.

A fitness equipment control system is provided. The system includes a receiver and a mobile apparatus, and performs the operations: generating a first control signal based on a training course of a user; transmitting the first control signal to the receiver to make the receiver generates a signal which is readable by the fitness equipment according to the first control signal and transmit the readable signal to the fitness equipment; receiving at least one physiological signal from at least one of the wearable devices worn by the user; based on the training course and the at least one physiological signal, generating a second control signal; and when the second control signal is generated, transmitting the second control signal to the receiver, wherein the receiver generates a signal which is readable by the fitness equipment according to the second control signal and transmits it to the fitness equipment.
