A vibration dampener for a racket includes a strip formed of elastomeric material having a first end part and a second end part, the strip having a first incision at the first end part and a second incision at the second end part, at least one hooking member having a hollow body having a hole into which the first end part is inserted and a hook formed at one side of the hollow body, wherein said at least one hooking member each is combined with the strip by inserting the first end part of the strip into the hole of the hollow body and pulling the elastomeric band until the strip and the hollow body makes a restraining knot.

A baseball swing trainer. The baseball swing trainer includes a housing having a base, a rear wall, and a top portion defining an open center area. A plurality of resistance blades extend downward from the top portion such that they are positioned within the open center area. A fastener is disposed on the rear wall for securing the swing trainer to a vertical structure such as a pole or tree. When a user swings a bat through the open center area, the resistance blades resist the motion of the bat. This enables the user to develop the muscles that are activated during the swing, which helps to increase swing speed and strength. A resistance band removably affixed to the vertical structure can be connected to the end of a bat to accelerate the bat through the natural swing plane, which enhances the neurological firing rate related to swing musculature.

A tennis analysis system analyzes tennis game play and generates game statistics for one or more players involved in a tennis session including match play. The system involves electronic portable devices that may be in a form of a dampener device. The portable devices can be mounted on tennis rackets for capturing stroke and other game related data during tennis play. Further, supplemental data may also be captured using personal devices such as mobile phones. The data generated by the electronic portable devices and personal devices can be used in combination by the tennis analysis system to perform game analysis.

This disclosure relates to systems, media, and methods for quantifying and monitoring exercise parameters and/or motion parameters, including performing data acquisition, analysis, and providing scientifically valid, clinically relevant, and/or actionable diagnostic feedback. Disclosed embodiments may receive real-time sensor data from a motion sensor or sensors mounted on a user and/or equipment while a user performs a test motion. Disclosed embodiments may also calculate a test motion profile based on the real-time sensor data, the test motion profile describing a multi-dimensional representation of the test motion performed by the user or computed motion profiles. Disclosed embodiments may include comparing the test motion profile to a template motion profile to determine a deviation amount for the test motion profile indicating how the test motion deviated from the template motion profile. Still further embodiments may correlate test motion profiles over time with health indicators.

A training or exercise apparatus may have a base and an adjacent movable armature or frame that carries a riding member, or shuttle, or carrier. The carrier has an engagement interface with an element of sporting or exercise equipment. The sporting or exercise equipment is engaged by the user, typically by being grasped. The apparatus defines a physical or virtual schedule describing an arc for a swing in the particular activity. The apparatus may include a manual or electronic means of imposing resistance to the motion. This resistance may be adjustable, and may be programmable as a function of one or both of position and speed. The apparatus may include an array of sensors such as may be used to determine the pre-existing stroke, and such as may be monitored during training to assess progress. The apparatus may be operated passively, or it may be operated interactively in a manner in which real-time feedback causes the apparatus to adjust resistance to the motion.

A shaft having an upper end; a first horizontal arm fixedly attached to the upper end of the shaft and a second, semi-rigid, flexible side arm fixedly attached to the first horizontal arm such that the second semi-rigid, flexible side arm bendably extends beyond the terminating end of the first horizontal arm, with a slightly downward slope; and means for releasably attaching to the side of a tennis ball provided on the second, semi-rigid, flexible side arm, such that when the tennis ball is attached to the second semi-rigid, flexible side arm, its slightly downward slope and slight curve provides a visual perception that the tennis ball is traveling on its way down to the trainee, while simultaneously being held in a manner which allows the trainee's racquet to travel up on, through and over the tennis ball, thereby repeatedly and consistently placing the tennis ball within the racquet's sweet-spot, without impeding the trainee's stroke.

An athletic swing trainer permits an athlete to swing a trainer at speeds far in excess of the athlete's conventional swing speeds and to confirm to the athlete that the practice swings made with the trainer at these extremely high speeds have been technically properly executed. Armed with this experience, the athlete is then able to swing the athlete's own conventional club, bat or racquet at speeds which, though lower than the athlete's trainer swing speeds, are significantly higher than the athlete's conventional club swing speeds. After six or seven trainer swings, an athlete's swing speed at point of contact of a conventional golf club, bat or racquet with a corresponding ball is typically increased in a range of 5 to 15%.

A training device and method for teaching a user the proper execution of various elements of an athletic swing. The swing training device incorporates a sliding member that simulates the impact of striking an object providing audible, visual and tactile feedback to the user pertaining to the proper execution of the swing, and displaces a force capture member a distance proportional to the force generated by the swing, and maintains this position until reset by the user. This allows the swing training device to quantify the force generated by the swing at the critical moment of impact. Further, the swing training device incorporates a movable stop that allows the device to be configured to provide for training methods that focus on the proper execution of specific swing elements, and it provides a means of quickly resetting the device for the execution of subsequent swing, thus maximizing training time.
