BRIEF SUMMARY OF THE INVENTIONThe subject matter described herein provides rotational swing stability training for athletes, such as baseball players, golfers, and other types of athletes, that use rotational swings to improve rotational energy accumulation and transfer during a rotational athletic swing. An apparatus for training in rotational swing stability includes a harness with a mechanical resistance attachment guide that moveably couples a first end of a mechanical resistance element to the harness. A second end of the mechanical resistance element is coupled to an anchor point. The mechanical resistance attachment guide provides an approximately constant radius attachment point for the first end of the mechanical resistance element relative to an axis of rotation of the athlete throughout a rotational athletic swing. The apparatus allows the athlete to rotate relative to the anchor point with approximately constant resistance to lateral and vertical movement provided by the mechanical resistance element when lateral and vertical rotational stability is maintained. Resistive feedback is provided to the athlete when a lateral or a vertical movement occurs during the rotational athletic swing by changes in resistance of the mechanical resistance element. As such, the apparatus trains the athlete through resistive feedback to maintain lateral and vertical rotational stability throughout the rotational athletic swing to improve rotational energy accumulation and transfer during the rotational athletic swing.
The mechanical resistance attachment guide may be flexible or rigid and automatically adjusts vertically for a height of the athlete and a distance from the anchor point. Selectable resistance for the mechanical resistance element may be based upon weight or body mass of the athlete. The mechanical resistance element may include an elastic portion and a non-elastic portion. The non-elastic portion may further be adjustable to allow the athlete to adjust a length of the mechanical resistance element for a height of the athlete or for a distance from the anchor point. Additionally, the athlete may adjust the mechanical resistance element to increase or decrease lateral and vertical resistance created by the combined elastic and non-elastic mechanical resistance element for weight or body mass of the athlete.

The subject matter described herein provides rotational swing stability training for athletes, such as baseball players, golfers, and other types of athletes, that use rotational swings to improve rotational energy accumulation and transfer during a rotational athletic swing. An apparatus for training in rotational swing stability includes a harness with a mechanical resistance attachment guide that moveably couples a first end of a mechanical resistance element to the harness. A second end of the mechanical resistance element is coupled to an anchor point. The mechanical resistance attachment guide provides an approximately constant radius attachment point for the first end of the mechanical resistance element relative to an axis of rotation of the athlete throughout a rotational athletic swing. The apparatus allows the athlete to rotate relative to the anchor point with approximately constant resistance to lateral and vertical movement provided by the mechanical resistance element when lateral and vertical rotational stability is maintained. Resistive feedback is provided to the athlete when a lateral or a vertical movement occurs during the rotational athletic swing by sensing changes in resistance of the mechanical resistance element. As such, the apparatus trains the athlete through resistive feedback to maintain lateral and vertical rotational stability throughout the rotational athletic swing to improve rotational energy accumulation and transfer during the rotational athletic swing.
The mechanical resistance attachment guide may be flexible or rigid and automatically adjusts vertically for a height of the athlete and a distance from the anchor point. Selectable resistance for the mechanical resistance element may be based upon weight or body mass of the athlete. The mechanical resistance element may include an elastic portion and a non-elastic portion. The non-elastic portion may further be adjustable to allow the athlete to adjust a length of the mechanical resistance element for a height of the athlete or for a distance from the anchor point. Additionally, the athlete may adjust the mechanical resistance element to increase or decrease lateral and vertical resistance created by the combined elastic and non-elastic mechanical resistance element for weight or body mass of the athlete.
Within
As described above, the batter 10 is shown using the swing stability training system 100 for lateral and vertical rotational swing stability training. The swing stability training system 100 includes a harness 102 attachable at least circumferentially around a waist area of an athlete, such as the example batter 10. The harness 102 may include any type of fastening system (not shown within
The harness 102 includes a flexible mechanical resistance attachment guide 104 coupled to the harness 102 via any suitable mechanism. As can be seen from
The flexible mechanical resistance attachment guide 104 may be constructed of any reasonably durable material, such as leather, nylon, plastic, metal, or any other material, either alone or in combination with one another to allow a flexible attachment mechanism to the harness 102. For example, the flexible mechanical resistance attachment guide 104 may include a cloth or wire rope, a cloth or wire rope covered with plastic or other tubing, or a nylon webbed strap. Many other possibilities exist for achieving a flexible construction for the flexible mechanical resistance attachment guide 104 and all are considered within the scope of the present subject matter.
It should be noted that while the flexible mechanical resistance attachment guide 104 is shown in association with the example swing stability training system 100 as coupled to the harness 102 at two locations, the flexible mechanical resistance attachment guide 104 may be coupled to the harness 102 at two points different from those shown in
It should also be understood that, while the vertical axis of rotation 20 is illustrated within
A mechanical resistance element 106 is shown coupled to the harness 102 via a rotatable coupling element 108 and a removable coupling element 110 to the flexible mechanical resistance attachment guide 104. The mechanical resistance element 106 is also shown coupled via a removable coupling element 112 to the anchor point 24. The mechanical resistance element 106 may be constructed of any material that may provide resistance to lateral and vertical movement of an athlete. For example, the mechanical resistance element 106 may be constructed from rubberized compounds, elastic compounds, rope, wire, cable, or any other material capable of being fastened to the respective locations described herein. Further, for implementations where lateral or vertical movement of an athlete are acceptable, the mechanical resistance element 106 may be constructed of a material with longitudinal elastic properties. The longitudinal elastic properties may be selected based upon an extent of allowable lateral and vertical movement and for weight or mass of the athlete. For implementations where lateral or vertical movement of an athlete are not desirable, the mechanical resistance element 106 may be constructed of a material without longitudinal elastic properties. In either situation, the mechanical resistance element provides either varying or fixed resistance, respectively, to lateral and vertical movement of the athlete.
The rotatable coupling element 108 is represented within this example as a pulley wheel system. The rotatable coupling element 108 may be constructed as a metal pulley wheel system, an alloy pulley wheel system, a plastic pulley wheel system, or a composite pulley wheel system. Other possibilities exist for construction of the rotatable coupling element 108 and all are considered within the scope of the present subject matter. It should also be noted that the rotatable coupling element 108 may be configured in any suitable fashion to allow the mechanical resistance element 106 to move along the flexible mechanical resistance attachment guide 104 during a rotational athletic swing and provide resistance to lateral and vertical movement of the athlete relative to the anchor point 24 to provide feedback to the athlete.
The removable coupling element 110 and the removable coupling element 112 are illustrated within the example swing stability training system 100 as carabiners. However, it is understood that any suitable fastening mechanism may be used to allow an athlete, such as the batter 10, to readily connect the harness 102 to and disconnect the harness 102 from him or herself and from the anchor point 24 during rotational athletic swing training sessions. The removable coupling element 110 and the removable coupling element 112 may be constructed of any suitable material, such as metal, plastic, cloth rope, wire rope, or any other material. Accordingly, any such fastening mechanism or material is considered within the scope of the present subject matter.
It should be noted that while the present example swing stability training system 100 shows the mechanical resistance element 106 coupled to the flexible mechanical resistance attachment guide 104 and the anchor point 24 via additional elements, there is no requirement for any of these additional elements to be provided within any given implementation of a swing stability training system, such as the swing stability training system 100. Accordingly, the mechanical resistance element 106 may be coupled to the flexible mechanical resistance attachment guide 104 at one end and to the anchor point 24 at the other end in any fashion that allows the mechanical resistance element 106 to move along the flexible mechanical resistance attachment guide 104 during a rotational athletic swing and provide resistance to lateral and vertical movement of an athlete relative to the anchor point 24 to train the athlete to maintain lateral and vertical rotational stability throughout the rotational athletic swing.
For purposes of the present description, it is understood that the mechanical resistance element 106 and other mechanical resistance elements described apply a resistive force to lateral and vertical movement of an athlete, such as the batter 10. A longitudinal force vector 30 is illustrated in
For example, if the batter 10 moves away from or toward the anchor point 24 laterally during a rotational athletic swing, the batter 10 will sense a corresponding increase or decrease in lateral resistance applied by the horizontal force component 32 of the longitudinal force vector 30. Similarly, if the batter 10 extends or lowers vertically during a rotational athletic swing, the batter 10 will sense a corresponding increase or decrease in resistance applied by the vertical force component 34 of the longitudinal force vector 30. Accordingly, an athlete may be trained to respond to changes in resistive feedback to minimize or strengthen any lateral or vertical movement that may be desired for a given sport to improve rotational energy accumulation and transfer during a rotational athletic swing.
It is understood that the longitudinal force vector 30 is represented with an arbitrary vector length within
The longitudinal force vector 30, the horizontal force component 32, and the vertical force component 34 are not illustrated in subsequent figures for ease of illustration purposes. However, it is understood that the forces discussed above provide resistive feedback to lateral and vertical movement of an athlete when attached to an anchor point at a level other than horizontal to a hip of an athlete. It should also be noted that, while the present subject matter is described to apply both lateral and vertical resistance to movement of an athlete, the present subject matter may also be used to provide lateral resistance alone by placing an anchor point at a level horizontal to a hip of an athlete.
As can be seen from
As such, lateral and vertical feedback is provided to the batter 10 via the approximately constant resistance when the batter 10 maintains lateral and vertical rotational stability. Additionally, feedback is also provided to the batter 10 via changing resistance when the batter 10 does not maintain lateral or vertical rotational stability and imparts lateral or vertical movement to a rotational athletic swing. It should be noted that, while the present subject matter describes minimizing lateral or vertical movement of the athlete during a rotational athletic swing, it is understood that certain sports require lateral or vertical movement of the athlete during a rotational athletic swing. In such endeavors, an increasing or decreasing resistance to that lateral or vertical movement may be provided as feedback to the athlete to assist that athlete in gauging how much lateral or vertical movement is being performed. As such, the present subject matter may be used to provide varying feedback based upon such lateral or vertical movement of an athlete during a rotational athletic swing without departure from the scope of the present subject matter.
It should be noted that while the present example discusses use of an approximately constant resistance via the mechanical resistance element 106, material selection may also allow for variations, such as increasing or decreasing resistance based upon lateral or vertical movement of an athlete relative to the anchor point 24. As such, other variations in resistance are possible and considered to be within the scope of the present subject matter. Additionally, a mechanical resistance element may be selected to provide a resistance based upon weight or body mass of the athlete.
A tension radius arrow 504 is illustrated to show that the mechanical resistance element 502 applies resistance to lateral and vertical movement of batter 10 away from the anchor point 24. The tension radius arrow 504 may be oriented as the longitudinal force vector 30 of
Based upon the description above, without lateral or vertical movement of the athlete, the example swing stability training system 100 provides approximately constant resistance throughout the rotational athletic swing by allowing the flexible mechanical resistance attachment guide 104 to flex and reshape based upon the resistance applied by the mechanical resistance element 502 relative to the anchor point 24. Additionally, the flexible mechanical resistance attachment guide 104 automatically adjusts radially based upon the rotational athletic swing to maintain an approximately constant radius arc of travel of the first end of the mechanical resistance element 502 relative to the vertical axis of rotation 20 of the athlete when the harness 102 is attached to the waist area of the athlete. The approximately constant radius arc of travel of the first end of the mechanical resistance element 502 allows the mechanical resistance element 502 to maintain approximately constant resistance throughout a rotational athletic swing when rotational stability is maintained relative to the vertical axis 20 and the anchor point 24. Accordingly, without lateral or vertical movement, the lateral and vertical resistance applied by the mechanical resistance element 502 relative to the anchor point 24, and thereby the feedback to the athlete, may remain approximately constant throughout the rotational athletic swing to improve and maintain lateral and vertical rotational stability of the athlete. Additionally, feedback may be provided to the athlete for any variations in lateral or vertical position throughout the rotational athletic swing.

The rigid mechanical resistance attachment guide 706 provides a circumferentially moveable approximately constant radius attachment location relative to an axis of rotation of the athlete throughout a rotational athletic swing. As will be described in more detail below, at least a portion of the rigid mechanical resistance attachment guide 706 remains within a vertical anchor plane 26 throughout the rotational athletic swing.

The rigid mechanical resistance attachment guide 706 is shown coupled to the harness 702 via two fastening elements 708 and 710. The fastening elements 708 and 710 may be constructed of any suitable material capable of coupling the rigid mechanical resistance attachment guide 706 to the harness 702. For example, the rigid mechanical resistance attachment guide 706 may include fabricated ends that form the fastening elements 708 and 710 and the fastening elements 708 and 710 may be stitched into or onto the harness 702. The fastening elements 708 and 710 may also be tied, riveted, grommeted, or fastened through holes in the harness 702. The fastening elements 708 and 710 may also include a pivotal element, such as a hinge assembly, that couples the rigid mechanical resistance attachment guide 706 to the harness 702 and that allows the rigid mechanical resistance attachment guide 706 to automatically adjust vertically based upon a height of the athlete when the harness 702 is worn by the athlete or a distance to the anchor point 24. Many other possibilities exist for fastening the rigid mechanical resistance attachment guide 706 to the harness 702 and all are considered within the scope of the present subject matter.

It should be understood that the non-elastic portion 1606 and the elastic portion 1608 are shown as a nylon strap and an elastic strap for ease of illustration purposes only. Furthermore, it should be understood that, while the non-elastic portion 1606 is described as non-elastic relative to the elastic portion 1608, this is for ease of illustration purposes only. The non-elastic portion 1606 may have elastic properties without departure from the scope of the present subject matter. Additionally, the coupling element 1610 is shown without removable attachment capabilities. However, these representations should not be considered limiting. Many other possibilities exist for construction of non-elastic portion 1606, the elastic portion 1608, and the coupling element 1610 and all are considered within the scope of the present subject matter.
A buckle 1612 is shown integrated with the non-elastic portion 1606 with an exposed end 1614 that allows an athlete, such as the batter 10, to adjust a length of the combined mechanical resistance element 1600. The length may be adjusted by the athlete for a variety of reasons. For example, the athlete may wish to adjust the combined mechanical resistance element 1600 for the height of the athlete or for a distance from the anchor point 24. Additionally, the athlete may wish to increase or decrease lateral and vertical resistance and the resulting feedback created by the combined mechanical resistance element 1600 for weight or body mass of the athlete, or for other reasons. Accordingly, the adjustable nature of the combined mechanical resistance element 1600 allows flexibility in both distance from an anchoring location (not shown) and height of the athlete, and for weight or body mass of the athlete, without requiring components to be changed.
It should be noted that the elements of the combined mechanical resistance element 1600 may be constructed from a variety of materials. For example, the non-elastic portion 1606 may be constructed from leather, nylon, plastic, metal, or any other material, either alone or in combination with one another, such as a cable or a woven nylon material. Additionally, the elastic portion 1608 may be constructed from a spring or a rubberized compound. As well, the coupling element 1610 may be constructed from leather, nylon, plastic, metal, or any other material, either alone or in combination with one another. Many other possibilities exist for construction of the non-elastic portion 1606, the elastic portion 1608, and the coupling element 1610 and all are considered within the scope of the present subject matter.
Additionally, it should be noted that any of the harness 102, the harness 702, or the harness 1002 may be reversed so that the respective mechanical resistance attachment guide is on the opposite hip from that shown within the respective figures so that either left-handed or right-handed athletes may use the respective swing stability training system. It should also be noted that the harness 1302 does not need to be reversed to allow an athlete to switch from a left-handed stance to a right-handed stance to train in a rotational athletic swing.
Accordingly, a method has been described including enabling an athlete to be tethered via a harness and a mechanical resistance apparatus to an anchor point positioned approximately perpendicularly to and below a hip of the athlete; allowing the athlete to rotate through a rotational athletic swing with an approximately constant radius moveable attachment location to the harness for a first end of the mechanical resistance apparatus relative to an axis of rotation of the athlete; and providing an resistive feedback to lateral and vertical movement of the athlete during the rotational athletic swing relative to the anchor point via the mechanical resistance apparatus to train the athlete to maintain lateral and vertical rotational stability throughout the rotational athletic swing. Many variations on this method have been described above and all are considered within the scope of the present subject matter.
