A computer-implemented method for recommending an item of equipment, which comprises: gathering sensed data from a sensor; processing the sensed data in accordance with a biomechanical protocol to determine at least one performance indicator associated with a subject's execution of the biomechanical protocol; and determining at least one recommended feature of an item of equipment based at least in part on the at least one performance indicator. Also, an equipment recommendation system with specific application to hockey, which comprises: a camera configured to produce images representative of execution of a hockey shot of a given type by a subject; an I/O interface; and a processor connected to the camera via the I/O interface and configured to extract parameters from the images and to output, via the I/O interface, a hockey stick recommendation for the subject that is based on the parameters and on the given type of hockey shot.

A piece of sports equipment includes: a surface; and base paint including magnetic particles, the base paint being located on the surface of the piece of sports equipment, the magnetic particles being arranged based on a predetermined design after being subjected to magnetic field generated by one or more magnets. A method of manufacturing a piece of sports equipment includes: obtaining an object including one or more magnets arranged in a predetermined design; applying a base paint including magnetic particles to an exterior surface of the piece of sports equipment; while the base paint is fluid, positioning the piece of sports equipment within a magnetic field of the one or more magnets; and maintaining the positioning of the piece of sports equipment for at least a predetermined period, thereby allowing the magnetic particles in the base paint to arrange based on the predetermined design of the one or more magnets.

A hockey stick includes a shaft that includes an upper portion, a lower portion, and a transition portion disposed between the upper portion and the lower portion. The upper portion includes an upper end, wherein a line that is tangent to the upper end is nonlinear with the power portion and is substantially parallel with the lower portion. A midpoint of the shaft is included in at least one of the lower portion and the transition portion. The hockey stick also includes a blade that extends from the lower portion of the shaft, where a first plane defined by the lower portion and at least a point on the transition portion is generally transverse to a second plane defined by the blade.

A sporting good implement, such as a hockey stick or ball bat, includes a main body. The main body may be formed from multiple layers of a structural material, such as a fiber-reinforced composite material. One or more microlattice structures may be positioned between layers of the structural material. One or more microlattice structures may additionally or alternatively be used to form the core of a sporting good implement, such as a hockey-stick blade. The microlattice structures improve the performance, strength, or feel of the sporting good implement.
