A portable apparatus includes an exercise-measurement circuitry that measures exercise-related measurement data related to a user carrying out an exercise, a communication circuitry configured to provide the portable apparatus with wireless communication capability, and a processing circuitry configured to a perform operations. The operations include receiving the exercise-related measurement data from the exercise-measurement circuitry, receiving configuration data from an external user interface apparatus over a bidirectional wireless communication connection established through the communication circuitry and capable of transferring payload data to both directions, processing the exercise-related measurement data according to the received exercise-related parameters in order to obtain advanced exercise-related data, and communicating the advanced exercise-related measurement data to the user interface apparatus over the bidirectional wireless communication connection.

Improved techniques and systems are disclosed for determining the components of resistance experienced by a wearer of a wearable device engaged in an activity such as bicycling or running. By monitoring data using the wearable device, improved estimates can be derived for various factors contributing to the resistance experienced by the user in the course of the activity. Using these improved estimates, data sampling rates may be reduced for some or all of the monitored data.

A method of monitoring swimming activity includes: determining at least one of an actual relationship of a mobile device to water or an expected relationship of the mobile device to water; determining ranges to satellites, based on signals received by a satellite positioning system (SPS) receiver of the mobile device, in response to the signals being received by the SPS receiver when the at least one of the actual relationship of the mobile device to water or the expected relationship of the mobile device to water is a desired relationship of the mobile device to water; and determining a location of the mobile device based on the ranges to the satellites.

A swimming starting platform having a base supporting a tread surface and an anchor ledge for supporting swimmers. The base includes a shaft extending through an interior cavity of the base from a first side panel to a second side panel. An adjustment mechanism is coupled to an end of the shaft and positioned along the first side panel, where the adjustment mechanism is actuatable to rotate the shaft and adjust a position of the anchor ledge relative to the base of the starting platform.

Disclosed is a last lap light apparatus with extendible pole length, for submersible use in signaling, for example, in a swimming competition.

An apparatus and method for measuring a swimmer's speed and conveying the speed to the swimmer in real time includes a plurality of ultrasonic beacons each having a transducer configured to emit ultrasonic signals in a pool or other body of water within which the swimmer is swimming. A wearable, waterproof, ultrasonic receiver worn by the swimmer, receives the ultrasonic signals and generates corresponding signal data. The receiver's microcontroller captures and uses the signal data to calculate the swimmer's position and speed in real time, and conveys this information to a wearable, waterproof, user interface device worn by the swimmer, the user interface device including a near-eye display disposed on the swimmer's googles.

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.

User activity including both athletic activity (e.g., running, walking, etc.) and non-athletic activity (shopping, reading articles, etc.) may be monitored and tracked by an athletic monitoring and tracking device and service. The user activity may be used to award a user with an amount of virtual currency to encourage the user to continue various activities. In one example, users may use the virtual currency to purchase or otherwise acquire various products, services, discounts and the like. A user may track an amount currency earned and/or needed relative to an amount required to acquire a desired product or service. Additionally or alternatively, a visual appearance of a user device (e.g., a watch or athletic activity band) may change based on the user's activity level, an amount of virtual currency earned and the like.

A swim lane apparatus having one or more attachment or tethering devices. The one or more attachment or tethering devices are configured to couple or affix to a foundation of the pool. The swim lane apparatus has a first sidewall. The first sidewall is coupled to the one or more attachment or tethering devices. The first sidewall is configured to form a channel and direct a flow of water out of the channel when the flow of water enters the channel.

A swim training apparatus for use as a monofin for bilateral undulation power development. The apparatus includes a flexible, elongated member having a series of securing members, such as through-holes extending from the top surface of the elongated member through to its bottom surface, and fasteners configured and disposed to attach to the securing member, such as straps that can extend through the through-holes, to fasten the apparatus to a user's legs. A weight can be attached using similar attachments and fasteners to the apparatus to increase undulation during use.
