An exerciser includes: sensor installation units provided to be spaced apart from and face each other in a direction parallel; a radiation unit for radiating light, in a first sensor installation unit; a light receiving unit for receiving the light radiated from the radiation unit, in a second sensor installation unit; a speed detection unit for detecting a speed of the golf ball by checking a moment the golf ball passes; a position measurement unit for measuring a position of the golf ball; an operation control unit for performing calculation to detect an initial position value of the golf ball and a moving speed Vb and a moving distance Hb of the golf ball; and a storage unit for storing the measured speed Vb and distance Hb of the golf ball.

The present invention is disclosing a performance improvement system comprising a smart athletic flexible accessory and an electronic device communicably coupled with smart athletic flexible accessory. Smart athletic flexible accessory comprises a plurality of fabric sensors configured to measure data associated with a physical activity performed by a user and a first transceiver configured to transmit measured data. Electronic device comprises a second transceiver configured to receive measured data from smart athletic flexible accessory, and a microprocessor. Microprocessor is configured to analyze received data from receiver, generate a recommendation based on analyzed data, and cause a display screen to display generated recommendation.

In one example, a muscle exercise device includes a first arm and a second arm rotatably connected to the first arm, and the second arm and the first arm are configured to cooperatively define a recess having a shape that changes as one of the first arm and the second arm moves toward, or away from, the other of the first arm and the second arm. The muscle exercise device further includes a resistance element configured to reside in the recess and be compressed between the first arm and the second arm so as to assume a configuration similar to the shape of the recess. Finally, a wireless transmitter chip is disposed in either the first arm or the second arm, and the wireless transmitter chip is responsive to communications from an app residing on a user device.

The present disclosure generally relates to navigating, viewing, and sharing activity and workout data and interacting with workout and/or activity applications. In some examples, scrolling of activity data is based on the content being displayed. In some examples, friends' activity data may be viewed. In some examples, a notification and workout data for a friend's completed workout is received and displayed. In some example, the activity data received from friends is viewed and managed. In some examples, workout data for a multi-segment workout is displayed in a three-dimensional stack on a map. In some examples, a workout application operates in a limited mode until a touch input is received with a characteristic intensity that is greater than a threshold intensity.

A support part of a swimming start block. The front support part (18) is provided for a starting block (1) of a swimming race, which includes at least one base (9) to be fixed around a swimming pool, and a platform (5) which is mounted or fixed on the base (9). A foot of a swimmer as well as his hands are supported before the start of a race on the front support part. This front support part is arranged to be mounted interchangeably on a front portion of the platform (5) of the starting block (18) and can be an intelligent front support part with motion sensors and light source and race management electronics.

A starting block (1) including a supporting ledge device (10) for a start of a backstroke race. The supporting ledge device is at least partially integrated into the starting block. The supporting ledge device includes a support ledge (13) on which at least one foot of a swimmer can be supported before the start of a backstroke race. The support ledge is held from within a base (9) or a base plate of the starting block by fastening elements (11). Two flexible fastening elements in the form of straps are respectively connected to the two ends of the support ledge and to return means within the starting block at ends opposite the fixation to the support ledge.

The present disclosure discloses a calibration method for output force of strength-type intelligent fitness equipment, which belongs to the field of intelligent fitness, including: connecting a tension detection device to the strength-type intelligent fitness equipment; obtaining an actual tension of the strength-type intelligent fitness equipment by turning on the tension detection device to perform detection; obtaining a tension deviation based on a target tension of the strength-type intelligent fitness equipment and the actual tension; and calibrating the strength-type intelligent fitness equipment based on the tension deviation.

A method and device for controlling the magnetic resistance of an exercise bike, and an exercise bike are provided. The method for controlling magnetic resistance of an exercise bike includes: monitoring in real time a working state of an electromagnet, and judging by a control module whether a resistance provided by a magnetron wheel conforms to a currently set resistance, according to a monitoring result of the working state of the electromagnet and a relationship between the working state of the electromagnet and the resistance provided by the magnetron wheel; and the control module adjusting a working current of the electromagnet if the resistance provided by the magnetron wheel does not conform to the currently set resistance, to adjust a magnetic field strength of the electromagnet, so that the resistance provided by the magnetron wheel conforms to the currently set resistance.

An exercise apparatus includes a motor, an operating member driven by the motor, a sensor operable to detect engagement of a user with the operating member, and a controller in communication with the operating member and the sensor. The controller is configured to generate exercise use data when the operating member is driven by the motor. A communication interface is in communication with the controller. In response to the controller determining that the user is engaged with the operating member, the controller is configured to report the exercise use data to the communication interface. In response to the controller determining that the user is not engaged with the operating member, the controller is configured to stop reporting the exercise use data to the communication interface. The communication interface is configured to communicate the reported exercise use data to a third party.

A martial arts training system comprising: (a) one or more hand held targets; (b) one or more wearable devices; and (c) trainee log-in hardware installed in said target(s) and said wearable device(s).
