This disclosure relates to systems, media, and methods for quantifying and monitoring exercise parameters and/or motion parameters, including performing data acquisition, analysis, and providing scientifically valid, clinically relevant, and/or actionable diagnostic feedback. Embodiments may be related to systems, devices, methods, and computer-readable media for providing baseline-adjusted real-time feedback to a user. Embodiments may include determining a type of activity for the user. Embodiment may include receiving data from the one or more motion sensors indicating a time-dependent series of three axis acceleration data and three-axis orientation data. Embodiments additionally may include providing a graphical user interface with a real-time representation of the received data. The real-time representation may include a scaled representation of at least one dimension of the time-dependent series of three axis acceleration data and three-axis orientation data for at least one of the one or more motion sensors based on the updated baseline adjustment.

A sports and performance media positional detection system, comprising: at least two elements, with at least one element involved in the sporting activity; a power source; and machine-to-machine communication, which are collectively arranged such that if any two or more elements interact, their electromagnetic properties can be detected thus allowing the position of the interacting elements to be communicated to a decision maker. The system can be applied to at least one stationary element, which can be the playing surface, lines defining the boundaries, or a set of goalposts; and at least one moving element, which could be a ball, footwear, or the participants themselves. The system can also be applied to performance media capture.

The present disclosure provides a fitness guidance method, a device and a storage medium. The method includes: collecting a face image of a user in real time in response to detecting a sport event of the user; performing recognition on the face image; determining a current sport state of the user based on a face recognition result; and providing a prompt for advising the user based on the current sport state.

A method of calibrating a crank arm-mounted power meter includes receiving an angle measurement from a first sensor disposed on a crank arm, the angle measurement corresponding to an angular orientation of the crank arm. A predicted load measurement is then calculated based on the angle measurement and weight data for the crank assembly including the crank arm and stored in memory. A load measurement corresponding to a load on the crank arm is obtained and a zero offset value is then calculated by determining a difference between the predicted load measurement and the load measurement. Power calculation logic for determining power applied to the crank arm is then updated using the zero offset value.

Provided is a bicycle simulator including: a base portion; a frame support portion connected to the base portion to be movable in one direction and supporting a frame of a mounted bicycle connecting a front wheel and a rear wheel of the bicycle; a first sensor configured to sense a moving distance and a moving direction of the frame support portion in the one direction; a communication circuit configured to receive the moving distance and the moving direction of the frame support portion sensed by the first sensor; a processor configured to generate a bicycle avatar of which a traveling direction changes according to the moving distance and the moving direction of the frame support portion transmitted from the communication circuit; and a display configured to display a traveling state of the bicycle avatar.

An indication is received from a user to rack or unrack a digital weight. A motor is signaled to apply or remove tension to a cable couple to the motor based at least in part on the indication. The actuator is connected to the cable and is physically arranged to deliver a force to the user. The motor selectively tensions a cable in accordance with an exercise program.

A program is presented to a user including a stream of content including a first auditory content and a first visual content related to the workout. A context state of the user participating in the workout is determined based on information from a sensor. A responsive content is selectively added based on the context state of the user to the stream of content in a manner that avoids conflict with the stream of content.

A fencing training device including: a first part configured to be coupled to a fencing weapon; a second part configured to be coupled to a lower portion of a fencer's body; and a retractable connector disposed between the first and second parts. Also provided is a method of training a fencer to perform a lunge and a fencing training system for providing feedback to a fencer regarding improper technique.

A method of encouraging exercise collects motion data of a user of a type of exercise machine. It is determined whether the user is in a good state according to the motion data. If the user is deemed in a good state, the motion data are sent to a cloud server. Ranking information of multiple users on same type of exercise machine are received from the cloud server. The ranking information is displayed on a touch screen of the exercise machine. The method realizes interaction of the user on a virtual reality basis, and improves exercise motivation of the user.

In a first aspect, a system for monitoring a swing is provided that includes (1) a swing measurement device adapted to couple to a swinging object and to output a signal indicative of a characteristic of the swinging object; (2) a wireless transmitter coupled to the swing measurement device and adapted to wirelessly transmit the signal output by the swing measurement device; and (3) a wireless device adapted to receive the wirelessly transmitted signal and to provide information regarding the swinging object based on the received signal. The wireless device is a cellular telephone or personal digital assistant (PDA). Numerous other aspects are provided.
