A training device for improving stick handling and maneuvering includes a base mountable to a playing surface, with at least one elongate member arranged on the base and rotatable thereabout, the elongate member extending substantially parallel to the playing surface, a motor house within the base and connected to the elongate member provides rotational movement to the elongate member, the elongate member defining at least two openings between the elongate member and the playing surface, wherein rotation of the at least one elongate member serves to rotate the at least two openings, to thereby dynamically change the orientation of and access to the openings.

A bat swing training device has a base assembly, an arm assembly adjustably connected to the base assembly, and a suction assembly that extends through and out of the arm assembly to hold a ball in a stationary position. The suction assembly includes a coil hose connected to a pump, and an upper hose connected to the coil hose at one end, and removably connected to a nozzle assembly at an opposite end.

The subject invention comprises a system, and method of using the system, for providing improved alignment in multiple dimensions. Appropriate settings include woodworking, machining, and sports, although there are several other practical applications for this technology. This system allows for simultaneous alignment along the x, y, and z axes. Another embodiment of this invention incorporates the multi-dimensional alignment station with one or more horizontal alignment stations. Each of the alignment stations have a base and top, guides that fit into the station tops and bases, and positional locks that lock the rotating element into place relative to the base plate and the alignment guides in place within the alignment stations.

Anchored HydroResistance Speed Training is a running speed training apparatus and training method which is used/done underwater. The apparatus is used to firmly stabilize a floating person's hips while they carryout sprinting mechanics in a maximal rate of force development manner against the resistant environment of the water they are submerged in. The rationale is to enable water-resisted maximal rate of force production training using sprinting mechanics, where this otherwise is not feasible due to the lack of anchoring to a sturdy surface. The apparatus provides the necessary anchoring of a person to an affixed object and stabilizes the waist, iliac crest, anterior iliac spine, and thoracolumbar regions, without restricting limbs, thereby allowing the primary ranges of motion involved in sprinting. The base of the apparatus is firmly affixed to the floor of pools by way of a suction cup base or by being permanently installed into a pool floor.

A training device for teaching and practicing ball handling skills for basketball players or persons training for sports, the training device including stanchions positionable on a floor using attachment members, such as suction cups, or a flexible resilient layer. A crossbar extends between the stanchions. Flexible elements can be used to connect the stanchions to the suction cups. The lengths of the stanchions and crossbar can be adjustable to set the height of the crossbar above the floor and the separation of the crossbars. Detents can allow for adjustably fixing the lengths.

A method and system for determining concentricity of a multiple layer golf ball are disclosed herein. One or more images of a golf ball are generated using an X-ray source, a camera or a digital detector, and an image intensifier. An edge detection algorithm is preferably utilized. The method also includes calculating Y,Z center coordinates of the a best fit diameter or ellipse of the inner edge layer and outer edge layer of the multiple layer golf ball.

Methods for improving respiratory effectiveness including inhaling a breath and, while continuously holding the breath, swimming for a period of at least 10 seconds without exhaling or further inhaling, and inhaling a breath and, without exhaling or further inhaling, adopting, and holding for a period of at least 3 seconds, at least one stretch position, which requires constant muscular exertion to maintain.

The invention discloses a force adjustable universal displacement tensioner, including a suction cup assembly 1 and a housing 2; outer gear spring cover 3, coil spring covers and a rope puller 4 are arranged in the housing 2 coaxially through a coil spring shaft; coil springs are disposed in both the outer gear spring cover 3 and the coil spring cover; a pulling rope is disposed on the rope puller 4; one end of the pulling rope which extends out of the housing 2 is connected to a handle 5.

Firm feet is a shoe like device created by Sukari Barnes to aid the modern-day exerciser. 53% of adults 18 and over have met the physical activity guidelines for aerobic physical activity. (NationalCenter for Health Statistics. Centers for Disease Control, 2017.). Adult Americans are becoming increasingly concerned about their health, physical fitness, and appearance. Firm feet was created to assist a person who loves to do sit ups daily. It is a device that controls body placement by sucking your feet to the floor while performing sit ups. The shoe like device fits snuggly and completely over both feet with the ability to adjust to the person's size. A strap is placed around the ankles in the back of the foot and suction cups on the bottom of the device will suction to the floor securing both feet firmly to the floor. Firm feet is an ideal invention for people performing push-ups or whatever exercises that require straight up body positioning with their feet on the floor. Once exercising is complete, a button is pushed on the outer side of each shoe like device which will release the suction and straps on the back of the foot.
