Abstract: The present invention provides methods for maintaining electrolyte balance and hydration in a person habituated to strenuous physical exertion by assaying perspiration generated by the person under conditions of strenuous physical exertion to determine the volume of perspiration as a function of duration of exertion and the sodium content of the person's perspiration during strenuous physical exertion The person is assigned to one of a plurality of groups of individuals, each group differing in the amount of sodium present in the perspiration and having a unique rehydration solution. The invention also provides for a set rehydration compositions, each member of the set comprising sodium and chloride differing from the weight percentage of sodium in the other members of the set and each member of the set being perceptually labeled to distinguish that member from the other members of the set by one of the human senses.

Abstract: A system for delivering objects, such as soccer balls, the system including a delivery device and a methodology for training individuals that can be used with the delivery device, the delivery device including an accelerator that accepts, accelerates, and launches the balls with motion characteristics, and a control system having an electronic controller structured to store and execute a training program that includes ball service specifications and player service variables, ball speed and spin control inputs, and random selection of values within a range of values of the player service variables that include a starting position of the player relative to the device, a direction of motion of the player relative to the device, an identification of at least one location on the player's body to touch the ball, a time interval to wait before delivering the ball, and an action for the user to take with the ball.

Abstract: A system for delivering objects, such as soccer balls, the system including a delivery device and a methodology for training individuals that can be used with the delivery device, the delivery device including an accelerator that accepts, accelerates, and launches the object with motion characteristics, such as linear acceleration, angular acceleration, or a combination of both, and an assembly that adjusts the position of the accelerator to adjust an exit trajectory of the object that includes adjustment about a yaw axis, an elevation axis, and a spin axis of the object. Highly and accurate and consistent delivery of the object facilitates single and multi-player use for training, such as in the sport of soccer.

Abstract: Apparatus including a video baseball-simulating game and a special bat containing a combination of electronic, mechanical, and optical components for providing infrared radiation or other energy (typically electrical) that is modulated when the player swings the bat and thus actuates a centrifugal switch therein. Receiving and decoding means receive the energy and, responsive thereto, provide digital signals to software in the video game to control an animated batter in the visual display therein.An alternative form of the apparatus functions similarly, except that radiation is emitted from, and received at, a "home plate" on the floor and is modulated by the swinging of an ordinary bat to diffract a portion of the radiation in its path from emitter to receiver.

Abstract: An apparatus for the practicing of golf swings utilizing a motion sensor and a radiation source on the forehead of the user which projects a radiated signal when head motion is sensed. The signal is detected by a unit contemporaneously with the golfer's swinging either-a golf club, if he is outside, or a simulated golf club provided with a beam of radiation emanating from one end thereof, if he is inside. In the case of the simulated unit which may be used indoors, details of club head registry, (open, closed, square, sweet spot, slightly toward the toe, slightly toward the heel, toe, heel, top and bottom) swing, follow through, club head speed, tempo, distance the ball travels and the path of the ball are displayed and recorded.

Abstract: A flotation barbell for water exercise which includes an elongated handle member to which are attached two identical homogenous buoyant triangular end sections, shaped in the form of a triangular prism having two triangular ends and three rectangular sides. The buoyant triangular end sections are attached to the ends of the handle member so that the triangular faces of the end sections are transverse to the longitudinal axis of the elongated handle member, and the corresponding sides of the two end sections are coplanar. The ends of the handle member are inserted into apertures centrally formed between the triangular end faces in each section. An end plate, preferably triangular in shape, includes a central protrusion which extends so as to affixedly engage an end of the handle member, with the end plate pressing against the outer end face of the end section.

Abstract: A deep water exercise belt, which supports the user in deep water in an upright, running position so as to allow vigorous exercise without placing body weight on the legs, involves a waist encircling belt of flexible buoyant material of uniform thickness which is shaped to provide greater flotation at the back of the user. Shaping includes an increased width of the belt on the back while forming the bottom of the belt to avoid hip motion of the user. The belt may be constructed of a chemically cross-linked polyethylene having an extremely fine closed-cell structure. The interior surface of the belt is smoothed so as to provide a suction effect against the body, while the exterior surface may be roughly textured to provide additional resistance to movement through water. A separate band of elasticized material is intertwined through the buoyant belt so as to buckle at the front of the user and hold the exercise belt in close contact with the waist.
