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.

[Object] To analyze a contact phenomenon between objects can with a simpler configuration.

[Solution] Provided is an analysis apparatus including: an acquisition unit configured to acquire vibration data showing a vibration generated in a first object by having a second object come into contact with a first position on the first object; a first analysis processing unit configured to specify the first position by comparing a vibration characteristic shown by the vibration data, and a vibration characteristic defined for each position where the second object may come into contact with the first object; and a second analysis processing unit configured to estimate a velocity after the contact of the second object based on a velocity of the first object and the first position.

Disclosed is a method for providing sports training videos using a camera and a radar sensor. The present invention is configured so that, when a specific motion of a player is captured by means of radar sensors in a state where a player is being simultaneously captured in real time from various directions by means of one or more cameras during a game or training, only videos of an interval corresponding to the detected specific motion of the player are saved, thus making it possible to: analyze problems that the player has in the game or training through replays of the saved videos; correct problems that the player has during training on the basis of the results of the analysis by distinguishing between the player's incorrect posture and the posture suitable for the player's physical requirements, the player's posture during slumps and during good periods, etc.; correct the player's posture through comparison with the postures of good players and the maximization of the strengths of the player; prevent injuries caused by the player's incorrect posture; and improve skills through the minimization of the player's weaknesses.

Sensing devices including pliable e-textile pressure sensors are used in gloves intended to be worn against a user's hand, or a portion of a user's hand. Additional sensors, such as accelerometer(s), gyroscope(s) and geo-referencing sensor(s), may be incorporated in electronic devices that interface electronically with the pressure sensors and are mounted on or in proximity to a glove when in use. Systems and methods for storing, communicating, processing, analyzing and displaying data collected by sensor components for remote monitoring of conditions at hand surfaces, position and orientation data, movement data, and the like, are also disclosed. Sensors and sensor systems provide substantially real-time feedback relating to current body conditions, orientation and movement, and may provide notifications or alerts to users, coaches, etc., enabling early intervention when conditions indicate intervention is appropriate.

An interchangeable ground mount system comprises (a) a ground mount, (b) at least one post segment, and (c) an interchangeable head. A variety of interchangeable heads can be mounted to one or more post segments, which are inserted into a semi-permanently installed ground mount, typically for lawn and garden use.

Performance of a racket can be adjusted. A racket includes a grip, an annular frame that is provided with a plurality of through holes that penetrate from an inner circumferential face to an outer circumferential face, and a shaft that connects the grip and the frame in a shaft axis direction, the frame having a rear end side attachment part, on the outer circumferential face of the frame and on a side closer to the shaft in the shaft axis direction, where there is mounted a rear end side attachment to which a string tensely provided to the frame is routed, and the rear end side attachment being made of a material different from the frame.

A sports implement includes a main body portion, a handle portion extending from the main body portion, and a grip member. The main body portion includes a first contact surface, a second contact surface, and a sidewall positioned about a perimeter of each of the first and the second contact surfaces. The handle portion defines a handle central axis extending therethrough. The grip member includes a grip body portion and a grip end portion. The grip body portion is operably coupled with the handle portion. The grip end portion defines a grip central axis extending therethrough. The handle central axis is offset from and parallel to the grip central axis.

A portable exercise apparatus intended for indoor use. A vertical spine is constructed and mounted to a plurality of wall braces. The spine has a series of pairs of hooks aligned vertically. The user can then place either a pulley plate or a body into a desired hook. Hooks are configured such that when the pulley plate or body is placed therein, force in a downward or straight direction would not remove the pulley plate or body. A bench can be attached to the pulley plate or body which then allows a user to set or lie on and perform exercises using a resistance cord which can be connected to the body, pulley plate, and or braces.

A solution is provided to enhance motion detection and recognition of moving objects associated with various sports by intelligently embedding motion sensors into sport instruments such as tennis rackets, badminton rackets, baseball bats and golf clubs, that are swung in a three-dimensional (3D) space. The motion sensors embedded inside the sport instruments are securely locked and are detachable for replacement. A motion sensor inserted and locked inside a sport instrument is configured to detect motions associated with movements associated with the sport instrument. The motion parameters associated with the detected motion are collected through the embedded motion sensor and analyzed by a motion detection and recognition system. Based on the analysis of the motion parameters, various types of sports performance reports and performance improvement recommendations are generated for users of the sport instruments.
