Description

BACKGROUND

A successful sports swing impact requires square impact to the target of the swing, e.g., a ball, puck, or shuttlecock, with full arm and hand extension based on proper swing timing, technique, square target hitting, proper extension, muscle memory, repeatability, and confidence—all delivered in the short period of time it takes to make the square swing impact. Square swing impact will enable the player to direct the swing target to its intended destination, and critical to square swing impact is proper release into and extension through the target. Repeatability of square swing impact requires trained swing timing, technique, square target hitting, proper extension, muscle memory, repeatability, and confidence to consistently deliver square swing impact. Square swing impact can be successfully executed when the athlete has confidence to swing without the need to think about swing mechanics, thus performing square swing impact with subconscious support to maximize physical skill and intuitive mental abilities in support of successful shot completion. Keeping it simple and confident can help increase square swing impact, leading to improved technique, target striking performance, and play improvement. The compact swing trainer can be used for any sports swing including without limitation golf, baseball, softball, tee-ball, stickball, cricket, lacrosse, tennis, squash, racquetball, badminton, hockey, field hockey, lacrosse, and polo.

DETAILED DESCRIPTION

A device as disclosed herein utilizing a sliding and extendable rod, pipe, piston, or other sliding material designed to develop muscle memory, strength, technique, and flexibility for square swing impact and extension to enhance coordination and power, as well as to provide rehabilitative training based on repetition with immediate tactile, auditory, impact, and visual feedback, and that enables a user to train in partial swing and full swing modes and can be utilized indoors and outdoors.

The square swing impact technique is a complex movement that is best accomplished by the interaction of the alternating contraction and relaxation of various muscle groups. Because this movement occurs in less than two seconds and must be coordinated to the millisecond, it cannot be controlled by conscious thought. It must be trained in harmony with the subconscious mind. Thus while in training, it is desirable that athletes have continuous information and feedback throughout the entire movement that they are maintaining the correct relationship between the feet, legs, hips, torso, arms, neck, and head when making the square swing impact, all of which are facilitated by use of the disclosed device.

One facet of the uniqueness of the disclosed device, method, and system is that all of the needed muscle groups to effectuate the square swing impact, and to develop muscle memory, strength, technique, and flexibility for square swing impact to enhance coordination and power, as well as to provide rehabilitative training are worked, trained, and developed. The disclosed device, method, and system also permit the user to practice square swing impact without the need for open space, that is, the device, method, and system can be used indoors to improve square swing impact, whether as part of training itself, or while doing other activities such as watching television.

Use of the device method, and system provide immediate tactile, auditory, impact, and visual feedback to the user to help the user confirm proper technique and to do repetitions of the technique and thus improve technique, strength, muscle memory, and confidence. Use of the device method, and system provide also provide a compact swing trainer stick if held in the inverted and extended portion. The device method, and system focus on improved method training of the core and other muscles used in making the sports swing, with focus on those utilized for square swing impact. By use of the device method, and system in a controlled manner, the athlete is able to train strength, flexibility, technique, coordination, weight shift, rhythmic timing, repeatability, and confidence.

The device is a compact combination of materials, whether tubes, shafts, or other materials, that slide and extend when the proper square swing technique is made. The device provides immediate tactile, auditory, impact, and visual feedback to the user to help the user confirm proper technique and to do repetitions of the technique and thus improve technique, strength, muscle memory, and confidence. The timing is related to proper release and extension of the hands, wrists, and arms in the golf or other sports swing to effectuate and complete square impact.

The device also provides feedback concerning swing speed, swing velocity, swing force, swing energy, and energy transfer via a data measurement component integrated and/or attachable to the device, wherein the data measurement component may communicate with a user's smart phone, tablet, watch, or other computer device to provide user with information and analysis concerning the user's swing dynamics.
