A system and method for controlling a tension in an exercise apparatus are provided. The system includes an input/output (I/O) subsystem for permitting a user to enter at least one resistance value and for displaying a resistance exerted by the exercise apparatus; a controller configured to control the tension of the exercise apparatus based on the at least one resistance value entered by the user adjusting a position of a holder and moving a plurality of guides for selective attachment of tension members to catches on the exercise apparatus; and a power source connected to the controller and the I/O subsystem and configured to power the controller and the I/O subsystem.

A golf club comprising a head having a series of tracks within a cartridge that's removable from the inside of the club head, which forms a three-dimensional pattern; a plurality of weights for positioning along the channels of the cartridge, and a mechanism for securing the weights at arbitrary positions along the channels within the cartridge, so as to customize at least one of center of gravity and moment of inertia from the crown or sole of the club head. The channels can all interconnect with one another to allow a weight to be moved from one to another. The golf club can further have an articulating cover for at least a portion of the surface, the cover being for covering and concealing the cartridge situated within the club head and the weights therein, positioned along the channels thereof.

A weight training apparatus using hydraulics or pneumatics for applying positive and negative resistance closer to a user's maximum capacity throughout a lift is provided. The apparatus allows for weight training without weights. The apparatus may provide a more effective and safer mechanism for training than conventional techniques. An aerobic apparatus using hydraulics or pneumatics for a more realistic feel is also provided. Methods of using the devices are also provided.

A head guard is provided. The head guard includes one or more sensors as part of an sensory input and communications system. The head guard wirelessly communicates data to remote computing devices for intelligent data collection.

A training script device is described that conveniently allows a user to create a training script defining one or more steps of a workout routine, where each step may include an activity, a duration for performing that activity, and an intensity at which the activity is to be performed. Further, one or more steps of the training script can be self-starting in response to performance data detected by sensors of training script device executing the training script. This conveniently frees the athlete from having to continuously monitor the status of his or her workout activities. Still further, the training script device conveniently allows a user to transfer training scripts to other training script devices, so that athletes can share successful training scripts.

An electronic device includes: a communication interface configured to receive medical data of a user from a server; at least one processor electrically connected to the communication module; and a memory electrically connected to the at least one processor. The at least one processor is configured to: determine whether the user is in a rehabilitation condition based on the received medical data; when the user is determined to be in the rehabilitation condition, provide an exercise program corresponding to a recovery target part of the user using the received medical data; and provide feedback on the exercise program based on at least one of exercise performance data, biometric information, or an exercise-related recovery level of the user.

Described herein are systems and methods for favorably coordinating a timing relationship between a musculoskeletal activity cycle and a cardiac cycle of a user. A method may include repetitively detecting a signal that correlates to a blood volume in the user; determining an actual value of the signal that varies with the timing relationship; computing a trend of the actual value of the signal; and adjusting the movement guidance based on the trend of the actual value. A system may include a prompt device configured to provide recurrently a movement guidance to the user for guiding performance of the rhythmic musculoskeletal activity; a sensor configured to provide a signal that correlates to a blood volume in the user; and a processor configured to determine an actual value of the signal that varies with the timing relationship and to adjust the movement guidance based on the trend of the actual value.

Physical fitness assessment systems and methods and wellness assessment systems and methods are disclosed. One physical fitness assessment system includes an exercise device and a host computer. The exercise device is configured to track movement of the exercise device by a user, determine a current physical activity data of the user based on, at least, the tracked movement, and transmit the current physical activity data of the user. The host computer is configured to receive from the exercise device the current physical activity data of the user, receive a physical fitness assessment selection to apply to the current physical activity data, compare the current physical activity data against benchmark physical activity data correlated with the exercise device, determine a physical fitness assessment of the user, generate the physical fitness assessment image based on the physical fitness assessment of the user, and present the physical fitness assessment image.

During a personalized monitoring procedure facilitating safe and effective sport or rehabilitation activities, in the preparatory section user anamnesis and activity protocol data are recorded; at an idle phase, based on current heart rate measurement, we decide whether the activity can be continued; at a load phase, we monitor changes in physiological parameters, related to the physical activity, primarily parameters that determine safe heart operation and, if necessary, provide a warning; in a regeneration phase, heart rate deceleration stage is monitored, heart rate variability parameters are calculated, and the result obtained is taken into account when monitoring in relation to the next training, while evaluating the idle phase.

Related apparatus comprises a data processing unit connected to measuring electrodes and sensors and a display unit in wireless communication with the data processing unit. The latter is preferably a smartphone, while the data processing unit includes expert knowledge of the physiology of the monitored training that enables procedure execution.

Real-time and dynamically generated graphical user interfaces for competitive events and broadcast data are disclosed herein. An example method includes determining, for each of a plurality of individuals, at least one of an absolute performance threshold or a personal performance threshold; receiving a data feed from each of a plurality of workout devices associated with the plurality of individuals over a network, the data feed including at least one of real-time absolute performance data or real-time personal performance data; determining, for each of the individuals, a performance zone based on a comparison of at least one of the real-time absolute performance data and the absolute performance threshold or the real-time personal performance data and the personal performance threshold; generating a graphical user interface that includes a broadcast of a real-time video of an instructor leading a workout; and a real-time leaderboard overlaid on the broadcast.
