A table tennis racket 1 characterized in that the circumference of the blade 3 comprises a plurality of straight portions 9a-g, and in that the handle 2 is aligned with a central longitudinal axis 8 of the racket 1.

A pickleball paddle with segmented cores, comprising a plate body and a grip body, the plate body has a core, a frame and two surface layers, the frame is disposed on a periphery of the core, the core defines at least two ball-striking response parts adjacent to each other, a segment gap is formed between any two of the ball-striking response parts, the two surface layers are spaced apart from each other and respectively assembled on the core and the frame, and the grip body is formed from a bottom side of the frame of the plate body. Thereby, the core of the plate body is capable of deforming easily through the segment gaps between the ball-striking response parts, which is conducive to controlling a duration that a pickleball stays on the plate body, and also conducive to controlling a rotational force of the plate body on the pickleball.

Provided is a novel technique for a table tennis rubber that makes it easier to put a spin and is capable of giving higher batted ball speed. A table tennis rubber comprising: a spongy-like sheet; and a rubber sheet layered and adhered to the spongy-like sheet with a plurality of protrusions formed on the sticking surface of a main body of the rubber sheet to the spongy-like sheet, wherein the rubber sheet has a thickness of 1.6 mm or less in a layering direction on the spongy-like sheet, and ar/h is 52 or more, wherein ar denotes a value of the area percentage (%) of the protrusions to the sticking surface, and h denotes a value of the height (mm) of the protrusions.

A system for illustrating the flight of a sports ball includes a radar, an imager, and a controller. The imager is configured to image a moving sports ball. The controller is configured to (i) receive, from the imager, an image including the moving sports ball, (ii) receive, from the radar, radar data associated with the moving sports ball, (iii) determine, from the radar data, a portion of a trajectory of the moving sports ball, (iv) alter the image to illustrate the portion of the trajectory relative to the moving sports ball, and (v) output the altered image.

A ball collecting device with ball collecting module having a collecting component and at least one ball collecting module is disclosed. The collecting component has an accommodation space for accommodating at least one ball such that the ball can be collected into the accommodation space by rotating the collecting component. The ball collecting module is pivoted on the collecting component such that an angle is formed between the ball collecting module and a rotation axle of the collecting component, and the angle is smaller than 90 degrees or equal to 90 degrees. A constant distance between the ball collecting module and a plane is maintained when the ball is collected by the ball collecting device.

A presentation method includes performing analysis on a swing by using output data from an inertial sensor measuring the swing of an exercise appliance, finishing the analysis, and presenting analysis information based on at least one preset index regarding the swing, on the basis of finishing of the analysis.

A display method includes acquiring first attitude information of the hands of a subject holding an exercise equipment during standing still on the basis of an output from an inertial sensor (sensor unit) which measures a swing action of the subject (user) performing a swing with the exercise equipment (golf club) and is attached to at least one of the exercise equipment and the subject, acquiring second attitude information of the hands of the subject holding the exercise equipment at impact on the basis of an output from the inertial sensor, and displaying at least one of the first attitude information and the second attitude information.

Ball return devices may include a body having a front surface configured to return a ball incident thereon and a back surface. The body may be configured to be positioned at an angle to, and coincident with, an underlying surface, the angle between the ground surface and the body being variable. The ball return devices may also include an attachment mechanism coupled to the body and adapted to attach the body to an external anchoring mechanism.

Provided herein is a multi-purpose exercise apparatus for improving sports coordination with which a user may sense stimuli from inside and outside one's body and at the same time operate one's body functions so as to adapt to the given circumstances using body muscles when playing a football, volleyball, handball, tennis, table tennis game and the like, thereby improving abilities of adjusting one's body parts such as the user's correct posture, balance, timing, flexibility, agility and the like, especially, significantly improving the ball control technique, body senses, and judgment ability of ball game players or sports participants.
