Training accessories and methods for improving athletic techniques, such as, for example, tackling form for football. A display can be coupled to a piece of athletic equipment, such as a tackling dummy, and the display depicts a symbol at a time at which a player is or is about to interact with the equipment or perform a movement or action. An input is provided of the player's identification of the depicted symbol and compared to the symbol that was actually depicted. The player's correct identification of the depicted symbol can indicate that the player performed the movement or action, or the interaction with the equipment, with appropriate form. A player's failure to correctly identify the depicted symbol can indicate to a coach that the player may need further instruction on proper technique or form with which the movement or action, or the interaction with the equipment, should be performed.

A training device, including a frame having an interior opening and a support, a piece of conditioning equipment supported on the frame by the support, a resistance harness coupled to the frame, the resistance harness has a portion attachable to a user, and a cardiovascular exercise machine within the interior opening of the frame.

A sports training aid having a base member, a center pole secured to the base member, at least one body panel rotatably secured to the center pole, and a plurality of elastic legs connected between the at least one body panel and the base member. The at least one body panel is configured to rotate in a first direction about the center pole when impacted by an object, the at least one body panel rotating from an original position to a deflected position. The elastic legs are configured to cause the at least one body panel to rotate in a second direction, opposite to the first direction, when a force from the impact subsides, thereby returning the at least one body panel to the original position.

The present invention pertains to the field of material for physical education, gymnastics, swimming, climbing or fencing, ball games, training material and specifically to training apparatus or apparatus intended for particular sports, consisting of a basketball trainer device composed of a body in the form of a silhouette with a cavity for traversing a ball within a frame and training aim or with said cavity covered with a lining to train reception by the bounce of the ball on the lining; a conical base filled with a weight ballast to keep basketball trainer device upright; removable swivel wheels for movement; riatas of connection with the player, connection with several players or connection with another device and the player simultaneously; where the basketball trainer device has the ability to remain static or moving, rotate 360 and flex up to between zero degrees and fifty degrees measured from the vertical axis.

A padded punching surface incorporating elastic roping connected to a frame which allows the punching surface to be struck with a force of impact by a user so as to minimize swinging of the punching surface. The apparatus is an improvement on existing punching bags which enables easier convenient and more realistic combat training for athletes and users. The amount of swing for the punching surface can be adjusted by tightening or loosening the elastic roping. The punching surface can include an attached head shaped surface for more realism.

Methods and systems according to embodiments of the invention provide for a framework for privacy-preserving machine learning which can be used to obtain solutions for training linear regression, logistic regression and neural network models. Embodiments of the invention are in a three-server model, wherein data owners secret-share their data among three servers who train and evaluate models on the joint data using three-party computation (3PC). Embodiments of the invention provide for efficient conversions between arithmetic, binary, and Yao 3PC, as well as techniques for fixed-point multiplication and truncation of shared decimal values. Embodiments also provide customized protocols for evaluating polynomial piecewise functions and a three-party oblivious transfer protocol.

A support base for a training aid assembly includes opposing longitudinal support bars and first and second raised lips that extend between the opposing longitudinal support bars at a opposing end portions of the support base. An intermediate raised member extends between the opposing longitudinal support bars at an intermediate portion of the support base between the opposing end portions.
