An athletic coaching method and jersey system are provided. The method utilizes jerseys with securing elements attached thereto. Number panels having specific player numbers are secured to the jerseys for use during practice. Scout team players wear the jerseys during practice. Each scout team player has a different number to represent the jersey number of a player on an opposing team in an upcoming game. The method allows coaches to more realistically simulate a game against an opposing team in practice. When the opposing team changes for the next game, each scout team player can continue to wear the same jersey but change the jersey number by switching number panels to represent a different player on the team of the next opponent. Thus, jersey numbers can be changed so that a game can be simulated for any opponent.

This invention is an inexpensive, easy-to-use, and easy-to-manufacture device that can be placed on the edge of a pool so that a swimmer can use it to count laps without significantly disrupting the swimming. The invention is lightweight and portable so that one person can carry it around, place it on the pool before swimming laps, and remove it afterwards.

The present disclosure provides an exercise mat including a top surface and bottom surface, wherein a plurality of markings exist on the top surface. As used herein, an exercise mat is a substantially flat cushion-like structure which can be used in conjunction with exercises. The exercise mat may be used for exercise or recreational activities such as physical therapy, pilates, yoga, or any other activity where physical placement of the user's body on the exercise mat may be important for the performance of the exercise, evaluation of physical progress, and/or for the avoidance of injuries.

A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

An apparatus for counting attempts in a sporting game includes a housing with a display for displaying at least a running count of attempts; wrist band means having opposing first and second sides, being connected at the first side with the housing, and being sized and configured to encircle a person's wrist proximal the person's palm; an input contact member mounted at the second side of the wristband means for movement upon contact with the person's palm; an attempt input assembly operably connected with the input contact member to transmit an electrical signal upon detecting movement of the input contact member by the palm; and electronic processing and power elements for receiving input from the attempt input assembly and causing the display to display information related to the movement registered by the input contact member.

A universal swing training apparatus is provided that includes a sports-related implement and a slide mechanism. The implement includes a proximal section and a distal section that are spaced apart to form a gap there-between. The slide mechanism is inserted within this gap and is connected to the upper end of the proximal section and the lower end of the distal section. The slide mechanism includes a rail guide, a plurality of front ball bearings, a plurality of rear ball bearings, and a sliding rail assembly that are cooperatively configured to insure that this upper end and this lower end are coaxial when the sliding rail assembly is situated in a coaxial position on the rail guide, and permit a lateral shift of this lower end relative to this upper end during a swinging of the implement.

A sports wrist trainer comprising a first elongated swing member with grip attached to a second elongated swing member with head by means of a one way 90 degree hinge, and an elastic return means that returns and holds said swing members at a ninety degree angle one to the other. According to alternative embodiments, the wrist trainer is a bat used for learning batting swings or a golf club used for learning golf swings. The one way hinge rotates to provide a trainer having different swing configurations and to maintain the bat or club head facing the ball at impact just like at address. The elastic return means may be removed and the trainer used without it. A second one way 90 degree rotating hinge can be added to the first providing additional versatility and accommodating both right and left handed golfers.

A sleeve fits over the barrel of a bat. The sleeve defines an opening such that, when the sleeve is applied to the bat, a significant portion of the barrel of the bat is revealed. The sleeve is made of a light-weight, sound-dampening material, such that when the batter hits a pitched ball in an area of the bat covered by the sleeve, the normal “crack” or “ping” of the ball hitting the bat is not heard. Instead, the batter hears a duller, less sharp sound, providing immediate feedback to the batter that he/she did not hit the ball in the desired area of the bat.

A golf club fitting apparatus and a method for fitting using the apparatus are provided. The golf club fitting apparatus may be attached to a golf club and provide fitting information including effective lie angle, effective loft angle, stroke plane, and aiming verification information. That golf club fitting apparatus includes a first opening for receiving a shaft, second openings for receiving a collimated light source, third openings for receiving angle indicators, and a recess for securing the collimated light source in an alternate configuration.
