A computer-implemented American soccer training and evaluation method that includes subjecting a drilling user to pre-defined drilling protocol(s) of a plurality of American soccer drilling assemblies and obtain, from each pre-defined drilling protocol(s) of the plurality of American soccer drilling assemblies and from at least one sensor on each of the assemblies, at least one user physical characteristic of the drilling user. The user physical characteristic is communicated to an administrative server over a network, where it is stored and used to create a drilling user performance profile having individualized performance comparisons with respect to the at least one user physical characteristic of the drilling user and a performance benchmark. Then, the drilling user performance profile is communicated to at least one of a plurality of electronic computing devices of a plurality of consuming users for evaluation and review.

A stationary indoor “smart” training bicycle includes a unique combination of adjustable components to provide configurable dimensions to adjust the frame size of the indoor bicycle to properly fit a rider. A system is also provided to process a digital image of an outdoor bicycle and determine and translate dimensions and adjustments to the indoor bicycle to match one or more dimensions (lengths, angles, separations, etc.) of the outdoor bicycle.

A bicycle power meter includes a strain gauge, a signal processing unit, a processor, and a signal transmitter. The strain gauge is disposed on at least one of an outer peripheral wall and an inner peripheral wall of a stem of a bicycle. The signal processing unit connected to the strain gauge by signal correspondingly outputs an electrical signal based on a deformation of the stem detected by the strain gauge. The processor connected to the signal processing unit by signal receives the electrical signal sent by the signal processing unit and calculates a measuring value based on the electrical signal and sends the measuring value in an output signal. The signal transmitter connected to the processor by signal receives the output signal sent by the processor and converts the output signal to a wired or wireless signal and sends the wired or wireless signal to a terminal device.

An apparatus for permitting electrical connection between the exterior of an inflatable sports ball and electronics located inside the inflatable sports ball is provided. The apparatus comprises a support member, the support member having separate first and second through-holes provided therein for respectively connecting the exterior of the inflatable sports ball with the interior of the inflatable sports ball. An electrical connection port is located in the first through-hole of the support member for permitting an electrical connection to be made through the first through-hole. An air valve is located in the second through-hole of the support member, the air valve comprising an aperture for selective communication of air.

The present invention describes an electromechanical exercise machine that simulates the inertia and weight of a mass in Earth's gravity field and allows a user to move said simulated mass in the primary degrees of freedom of a traditional barbell free-weight system, with or without the use of various accessories.

A portable smart hand grip according to an embodiment of the present disclosure includes a first housing, a guide part combined with the first housing and including a first receiving portion and a second receiving portion, a second housing facing the first housing and having a first pressing portion and a second pressing portion which are received in the first receiving portion and the second receiving portion, respectively, a first elastic member disposed between the first pressing portion and the first housing, a second elastic member disposed between the second pressing portion and the first housing, a sensor received in the first housing for detecting a user's operation of the portable smart hand grip, a control circuit unit received in the first housing to control an operation of the sensor, and a battery unit received in the first housing to provide power to the control circuit unit.

A walking training system according to the present embodiment includes: a treadmill; a load distribution sensor; an imaging device that takes an image of a trainee; a specifying unit that specifies, from the image taken by the imaging device, whether a load detected by a load distribution sensor is a load received from a sole of a right leg of the trainee or a load received from a sole of a left leg of the trainee; and a determination unit that determines, based on a status of a load received from a sole of one leg, out of the right leg and the left leg of the trainee during walking training, in a standing state that is detected by the load distribution sensor, whether the sole of the one leg in the standing state is located within a load detection area of the load distribution sensor.

The present invention relates to a safety system for treadmills. The safety system includes at least one load/weight sensor and a small switch disposed within the base of the treadmill. The system also includes a comparator for comparing the weight of a user standing on the treadmill, and an input weight of the user displayed on a dashboard of the treadmill. The safety system allows the treadmill to activate only when the weight of the user is equal or more than the selected weight on the dashboard. The system can be integrated into a treadmill during manufacturing or can be retrofitted to existing treadmills. The system also controls various variables such as speed, duration and inclination of the treadmill.

A golf swing analyzer system for analyzing a golfer's golf swing. An inertial measurement unit (IMU) may be used to capture data regarding the swing. The IMU may be oriented along a hosel-axis and a face-axis to reduce the complexity of calculations to determine the path of the swing. Two IMUs may be used to permit correction of captured data, different orientations of the IMUs to increase accuracy of captured data, and a doubling of the captured data. The IMU may include a magnetometer that cooperates with a magnet that is adapted to indicate the time at or near impact of the head of the golf club with the golf ball. An LED system provides visual information to a user regarding the swing while the swing is being made.

Fight training equipment includes a training equipment body; a liner fixed inside the training equipment body; at least one telescopic arm fixed in the liner through a first elastic member; a pop-up device or a winding device arranged in the liner, a pop-up channel matched with each arm in a one-to-one correspondence manner being arranged between the liner and the training equipment body so that the arm extends from the liner to the outside of the training equipment body through the pop-up channel under the action of the pop-up device and is withdrawn to the middle part of the liner through the pop-up channel under the action of the first elastic member, or the arm is withdrawn from the outside of the equipment body to the middle part of a liner body through the pop-up channel under the action of the winding device and extends to the outside of the equipment body through the pop-up channel under the action of the first elastic member; an arm control assembly arranged on the training equipment body; and a drive device connected with the pop-up device or the winding device, the arm control assembly being connected with the pop-up device or the winding device through the drive device.
