A grip adjustment system comprising: a sleeve positionable, in use, on an object configured to be gripped by a user. The system also comprises a distributed array of actuators, each actuator being arranged to actuate a respective portion of the sleeve between a first position and a second position in response to an actuation signal; and a processor. The processor is operable to: receive a pressure distribution and an event quality indicator corresponding to an event of interest; determine an optimal grip based on the pressure distribution and the event quality indicator; select an actuator, of the distributed array of actuators, to be actuated based on the optimal grip; transmit the actuation signal to the actuator such that the shape of the sleeve is changed and the grip of the user is adjusted.

A pre-molded or moldable shaft grip includes a pre-configured or moldable section disposed within a substantially circular outer grip layer. A pre-configured or moldable section substantially conforms to a player's grip, facilitating consistent finger placement. The pre-configured section may comprise the shaft, a separate section, or multiple sections of varying durometer. The moldable section may include a layer of moldable material, or a cavity disposed between the outer grip layer and the shaft containing a moldable substance. Overall grip durometer can be adjusted by varying the pressure within the cavity.

A method for analyzing the game of a user of a racket (Ra) includes detecting an impact on the racket (Ra) from representative measurements of a shock to the racket (Ra) provided by a sensor assembly comprising at least one sensor sensitive to shocks linked to the racket (Ra) in a fixed manner in terms of movement. A moment of impact is associated with a detected impact, from the measurements transmitted by the sensor assembly. The impacts that are not related to strokes from a set of pre-determined strokes are eliminated on the basis of angular rotational velocity measurements, provided by a gyrometer (G) of the sensor assembly with at least one measurement axis and linked to the racket (Ra) in a fixed manner in terms of movement, taken during an interval of time around said moment of impact.

Tool grips and handles may be enhanced by the addition of modular inserts which compensate for two voids in the human hand. A first insert may fill a void in the palm of the hand while a second may fill one by the fingers. By filling the voids, a more natural, relaxed, and customizable grip may be achieved for almost any handle. Use of a plurality of inserts allows for customization according to hand size while the size of the inserts also accounts for the size, dimensions, and axes of the handle and tool in general. Meniscus-shaped inserts may be stacked on one another for optimum effect.

In the case of a tool with a grip, it is expected to be easy to handle and useful to prevent from slipping.

According to the present invention, while the grip is held firmly with the fingers and palm, it is possible to turn the grip by the specific finger or part of the palm, by pushing the mound within a range of movement of the mound, in hitting a ball back, providing the grip aid required to lower the load on the shoulder and forearm, and offer a health boost.

A handle for sport equipment comprises a tubular body (7) which extends along a longitudinal axis (L) and has an outer peripheral surface (8) adapted to be grasped by a user and shaped with a plurality of longitudinal faces (9) placed side by side in correspondence of edges (10) adapted to facilitate the positioning of the finger joints of the gripping hand by the user. The edges (10) are arranged along at least one pair of helical or spiral paths that develop around said longitudinal axis (L) with mutually opposite sign to subdivide each of said longitudinal faces (9) into a plurality of areas or flat surfaces (11) sized to accommodate a corresponding phalanx of the gripping hand of the user, each of said areas or flat surfaces (11) being perimetrically delimited by at least one pair of edges (10, 10) of each of the helical or spiral paths.
