Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority to and the benefit of U.S. Provisional Patent Application Ser. No. 61/601,252, filed Feb. 21, 2012, the disclosure of which is incorporated herein by reference in its entirety. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates generally to the field of athletic apparel, and more particularly to a garment for supporting a movement of an athlete during an asymmetrical athletic motion. 
     BACKGROUND OF THE INVENTION 
     Many movements carried out by an athlete during athletic activity may be considered to be somewhat symmetric in nature, in that the actions are carried out in a similar manner by both the left and right sides of the athlete. For example, actions such as running, skating, cycling, or paddling a kayak in a straight line generally entail similar, if mirrored, motions by the left and right sides of the athlete, with substantially the same range of movement and force generated by each side of the athlete with each movement. 
     Numerous sports however include motions that can be considered to be highly asymmetric in their execution as they may, for example, be performed or controlled mainly, or only, by a dominant hand of the athlete and/or be performed in a strictly asymmetrical manner. For example, when shooting, an ice hockey player will generally only strike the puck with either a left-handed swing or a right-handed swing, a golfer will generally only perform a swing as either a left-handed swing or a right-handed swing, the majority of baseball batters will generally only swing the bat as either a left-handed swing or a right-handed swing, a racquet sport player will generally only hold and/or control their racquet with their dominant arm, speed skaters tend to swing only one arm when circling a track, a soccer player often favors one foot over the other when striking the ball, football punters and kickers generally only strike the ball with their dominant foot, and football quarterbacks and baseball and softball pitchers generally only throw with their dominant arm. Examples of asymmetric athletic movements can be seen in  FIGS. 1A-1D . 
     For all these asymmetric athletic movements and activities the garments traditionally worn by the athlete, which are generally manufactured symmetrically (i.e., with the same materials, stitching, and design on both the left and right side), can restrict or otherwise working against the asymmetric movement of the wearer. For example, due to their symmetric construction, shirts worn by an ice hockey player may not stretch and deform in a manner optimal to the support of a repeated striking of the puck by either a left-handed or right-handed player. In fact, by failing to account for the specific repeated movements of an athlete carrying out an asymmetric-type motion, traditional garments may, in fact, resist the motion of the wearer (e.g., by providing resistance to the specific stretching of the garment produced by the asymmetric motion) and reduce the efficiency of the motion. For ice hockey and golf, for example, by acting against either or both of the backswing and forward swing of the motion (by inhibiting the range of the swing and/or partially counteracting the force generated by the swing) this resistance applied by the shirt could have a noticeable effect on the power and accuracy of the athlete&#39;s swing and shot. By failing to account for a repeated stretching or deformation of the garment in a particular direction, symmetrically manufactured garments may also be prone to wearing and ultimately tearing or otherwise failing at or near the location of the repeated stretch/deformation. 
     SUMMARY OF THE INVENTION 
     From the above, there is a need for a garment specifically adapted to reduce the resistance garment material applies to a wearer during asymmetric athletic motions, thereby increasing the efficiency of the asymmetric movement and, for example, facilitating an increase in the force an athlete can generate during the movement. As such, the present invention is directed towards improved garments, and associated methods of design, manufacture and use, for supporting a movement of an athlete during an asymmetrical athletic motion. 
     One aspect of the invention includes an asymmetric garment for at least a portion of an upper body of a wearer including a torso section having a neck opening for a wearer&#39;s neck and a torso opening for a lower portion of the wearer&#39;s torso, a first sleeve for covering at least a portion of a first arm of the wearer, the first sleeve adjoining the torso section at a first end thereof and having an opening for a wearer&#39;s hand to extend through at a second end thereof, and a second sleeve for covering at least a portion of a second arm of the wearer, the second sleeve adjoining the torso section at a first end thereof and having an opening for a wearer&#39;s hand to extend through at a second end thereof. The garment further includes a first material portion including, or consisting essentially of, at least a portion of the first sleeve and at least a portion of the torso section, wherein the first material portion includes, or consists essentially of, a first material. The garment also includes a second material portion including, or consisting essentially of, at least a portion of the second sleeve and at least a portion of the torso section proximate the second sleeve, wherein the second material portion includes, or consists essentially of, a second material adapted to provide a lesser resistance to stretching than the first material to reduce resistance to a movement of the wearer during an asymmetrical athletic motion. 
     In one embodiment, the second material portion further includes a rear section of the torso section which may extend substantially vertically down the rear section from the neck opening towards, and possibly to, the torso opening. In one embodiment the second material portion includes a side section extending around at least a portion of a side of the torso section proximate the second sleeve, wherein the side section may, for example, extend helically downwards from a rear of the torso section to a front of the torso section. The second material portion can include a unitary expanse of the second material or a plurality of sections of second material connected to form a continuous expanse. The second material portion may also include a plurality of spaced apart material portions. 
     The first sleeve and the second sleeve may include a raglan sleeve. The first material portion may be stitched to the second material portion by a flat-lock stitch which may, for example, include a nylon thread. In one embodiment, the first material includes a material adapted to provide at least one of a wicking property and cooling property. The first material may include, or consist essentially of, cotton, polyester, nylon, spandex, or a combination of two or more of those materials (e.g., a cotton-spandex blend, a polyester-spandex blend, and/or a nylon-spandex blend), and may, for example, include polyester or nylon with spandex for super stretch and recovery in either a circular knit or warp knit construction. The second material may also include, or consist essentially of, cotton, polyester, nylon, spandex, or a combination of two or more of those materials (e.g., a cotton-spandex blend, a polyester-spandex blend, and/or a nylon-spandex blend), and may, for example, include polyester or nylon with spandex for super stretch and recovery in either a circular knit or warp knit construction. The second material may be formed from a different material or combination of materials from the first material and/or be formed with different proportions, weaves, and/or orientations of materials from the first material. In one embodiment, the first and second materials comprise cotton-spandex, polyester-spandex, or nylon-spandex blends with different proportions of spandex therein. In one embodiment, the second material is adapted to preferentially stretch in a limited number of directions and, for example, in only one direction. 
     In one embodiment, the garment includes a third material portion, wherein the third material portion includes, or consists essentially of, at least a portion of the first sleeve and at least a portion of the torso section proximate the first sleeve. The third material portion may include, or consist essentially of, the first material or a different third material. The third material portion may also include at least one of a rear section extending substantially vertically down a rear of the torso section and a side section extending helically around at least a portion of a side of the torso section proximate the first sleeve. The third material portion may be arranged either substantially symmetrically or asymmetrically with the second material portion about a central vertical axis of the garment. 
     One embodiment of the garment may include one or more supporting elements extending over or underlying at least a portion of the garment and, for example, at least one shoulder or elbow of the garment. The one or more supporting elements may include one or more reinforcement elements of, for example, the first material, the second material, or a different third material. The one or more supporting elements may include one or more non-slip material, such as polymeric elements, on an outer surface of the garment, and the non-slip elements may include, or consist essentially of, silicone or rubber or other such materials with a similar performance. 
     The garment may include one or more elasticity elements adapted to support a movement of the wearer during the asymmetrical athletic motion. The one or more elasticity elements may, for example, be disposable on a first area of the garment to store energy by elastic elongation under a first movement of a portion of the body of the wearer and to release the stored energy under a second movement of the portion of the body in substantially an opposite direction. 
     Another aspect of the invention includes a method of supporting a movement of an athlete during an athletic motion. The method may include identifying a body portion of an athlete subject to resistance to a movement of the body portion by an article of apparel worn by the athlete during an asymmetrical athletic motion, and providing an asymmetric garment adapted to reduce the resistance to the movement of the body portion during the athletic motion. The garment includes a first material portion including, or consisting essentially of, a first portion of the garment, wherein the first material portion includes, or consists essentially of, a first material. The garment also includes a second material portion including, or consisting essentially of, a second portion of the garment, wherein the second material portion includes, or consists essentially of, a second material adapted to provide a lesser resistance to stretching than the first material, and wherein the second portion of the garment at least partially covers the body portion subject to resistance. 
     In one embodiment, the asymmetric garment includes a torso section having a neck opening for a wearer&#39;s neck and a torso opening for a lower portion of the wearer&#39;s torso, a first sleeve for covering at least a portion of a first arm of the wearer, the first sleeve adjoining the torso section at a first end thereof and having an opening for a wearer&#39;s hand to extend through at a second end thereof, and a second sleeve for covering at least a portion of a second arm of the wearer, the second sleeve adjoining the torso section at a first end thereof and having an opening for a wearer&#39;s hand to extend through at a second end thereof. The first material portion may include the first sleeve and at least a first portion of the torso section, and the second material portion may include at least a portion of the second sleeve and at least a second portion of the torso portion proximate the second sleeve. 
     Another aspect of the invention includes an asymmetric garment for at least a portion of a lower body of a wearer. The garment includes a torso section having a torso opening for a lower portion of the wearer&#39;s torso, a first leg section for covering at least a portion of a first leg of the wearer, the first leg section connected to the torso section at a first end thereof and having an opening for a wearer&#39;s foot to extend through at a second end thereof, and a second leg section for covering at least a portion of a second leg of the wearer, the second leg section connected to the torso section at a first end thereof and having an opening for a wearer&#39;s foot to extend through at a second end thereof. The garment further includes a first material portion including, or consisting essentially of, at least a portion of the first leg section and at least part of the torso section, wherein the first material portion includes a first material. The garment also includes a second material portion including, or consisting essentially of, at least a portion of the second leg section and at least a portion of the torso section proximate the second leg section, wherein the second material portion includes a second material adapted to provide a lesser resistance to stretching than the first material to reduce resistance to a movement of the wearer during an asymmetrical athletic motion. 
     A further aspect of the invention includes an asymmetric garment for at least a portion of a body of a wearer including a first material portion forming a first portion of the garment, wherein the first material portion comprises a first material, and a second material portion forming a second portion of the garment, wherein the second material portion comprises a second material. The first material portion and second material portion are arranged asymmetrically with respect to a central vertical plain of the garment, with the second material being adapted to provide a lesser resistance to at least one of stretching or twisting than the first material to reduce resistance to a movement of the wearer during an asymmetrical athletic motion.

     DETAILED DESCRIPTION 
     The invention described herein relates generally to an improved garment for supporting a movement of an athlete during an asymmetrical athletic motion. This may be achieved, for example, by constructing the garment with carefully selected portions being formed from one or more materials specifically adapted to reduce the resistance to movement (e.g., resistance to stretching and/or twisting) provided by the garment and/or to provide support to a specific movement of a wearer. Such garments may be used to reduce the resistance to, and support, athletic motions involving, for example, throwing, kicking, striking, and/or turning. Sports utilizing such asymmetric motions include, but are not limited to, ice hockey, field hockey, lacrosse, baseball, softball, basketball, football, soccer, racquet sports (e.g., tennis, badminton, squash, racquetball, etc), golf, track and field events (e.g., javelin, shot put, discus, hammer, pole vault, hurdling events etc), handball, cricket, water polo, hurling, and archery. 
     Various garments may be provided with such asymmetrically positioned material construction to enhance the performance of an asymmetric motion utilizing any appropriate muscle group and/or body portion of an athlete. Example garments for the upper body of a wearer include, but are not limited to, long-sleeved shirts, % length-sleeved shirts, short-sleeved shirts, sleeveless shirts, tank tops, arm sleeves, and/or sports bras. Example garments for the lower body of a wearer include, but are not limited to, pants, tights, shorts, leg sleeves, and/or socks. The asymmetrically positioned material construction may also be applied in garments covering both a portion of the upper and lower body of a wearer (e.g., jumpsuits). The garments may be designed to be loose-fitting, “close-to-body” or snug-fitting, or even compression-fitting. 
     One aspect of the current invention includes a garment specifically designed to reduce and potentially minimize resistance to asymmetric athletic motions and, in some embodiments, even store and release energy supporting the motion, thereby substantially increasing the efficiency of the athlete&#39;s movement. For example, various garments according to the current invention include material sections placed asymmetrically over the body or a wearer to allow for additional stretching (with reduced resistance) in targeted portions of the garment (and/or in specific directions) that undergo the most stretch and strain during a repeated asymmetric movement. These garments may, for example, include one or more first materials constituting a majority of the garment, with carefully selected regions of the garment constructed from one or more second materials, or movement promoting materials, having differing structural properties from the one or more first materials. In one embodiment, the one or more second materials may provide less resistance to deformation (e.g., stretching) in one or more directions than the one or more first materials. The second material(s) may in addition, or alternatively, be lighter, more elastic, stronger, and/or possessing a lower friction coefficient than the first material(s). The second material may be positioned on the left side of a garment, the right side of the garment, or even on both sides of the garment. In various embodiments, the second material may also, or alternatively, be positioned only on a front, side, or a rear of the garment. Providing a garment that is specifically designed to reduce and potentially minimize resistance to a repeated asymmetric athletic motion also allows for increased wear resistance of the garment, thereby allowing the garment to maintain its structural integrity, and thereby functionality, longer. 
     The regions of the garment constructed from the second material(s) may be located over and/or adjacent to the body portion(s) of the wearer that undergo significant movement during the asymmetric motion. For example, the shoulder region providing the force generation for an ice hockey player (e.g., the right shoulder for a right-handed shot) may be covered by a shirt constructed from, or partially constructed from, a second material providing minimal resistance to stretching. As a result, as the hockey stick is drawn back and thereafter driven forward, resistance to the shot by the material of the shirt is minimized. The remainder of the shirt may be constructed from one or more first materials, with the first materials selected for purposes such as, but not limited to, durability, warmth, protection, style, etc. 
     Constructing garments with one or more first material(s) over a majority of the garment and with one or more second material(s) only on specifically targeted portions selected to enhance the performance of the wearer, allows the garment to be optimized for cost, durability, warmth, protection, style, etc, while still supporting the asymmetric motion repeatedly performed by the wearer. Constructing garments with different material portions having a different coefficient of friction may allows the portions having the larger coefficient of friction (i.e., the first material portions) to grip onto the skin or under-garment of the wearer, while the portions having the lower coefficient of friction (i.e., the second material portion) slide over the skin or under-garment of the wearer and thereby don&#39;t produce a significant friction force that could fight against the stretching, twisting, or extension of that portion of the body of the wearer. Such constructions may be advantageous, for example, for use in material portions for sports apparel such as, but not limited to, hockey shooting shirts. 
     In various embodiments, the one or more first and/or second materials forming part of the garment may include materials such as, but not limited to, cotton, polyester, nylon, spandex, or a combination of two or more of those materials. For example, the first and/or second materials may be formed from a cotton-spandex, polyester-spandex, and/or nylon-spandex blends such as, for example, cotton, polyester, or nylon with spandex for super stretch and recovery in either a circular knit or warp knit construction. In an alternative embodiment, other appropriate knit constructions may be utilized. The second material may be formed from a different material or combination of materials from the first material and/or be formed with different proportions, weaves, and/or orientations of materials from the first material. 
     In one embodiment, the first and second materials comprise cotton-spandex, polyester-spandex, or nylon-spandex blends with different proportions of spandex therein. For example, by forming the second material from a blend having a higher percentage of spandex than in the first material, the second material will allow for a greater degree of stretch to reduce resistance to the asymmetric athletic motion. In one embodiment, the second material is adapted to preferentially stretch in a limited number of directions and, for example, in only one direction. The first and second material(s) may be selected such that they provide the required support for the asymmetric motion of the athlete while not substantially hindering any symmetric motions carried out by the athlete (e.g., running or skating) while participating in a sport. 
     The second material can be adapted to stretch equally in all directions, thereby allowing for the multi-directional stretching and deformation of the second material portion supporting the athlete&#39;s movement. Alternatively, the second material can be adapted to preferentially stretch in a limited number of directions, and even in only one direction, thereby supporting the specific stretching of the garment in only limited directions. By preferentially stretching in only one direction (or in a limited number of specific directions) the garment may be used to encourage the athlete to turn and/or stretch in a specific direction (i.e., the direction that causes the minimum resistance from the second material), thereby potentially providing a training functionality to the garment. As a result, careful positioning and orientation of selectively stretchable second material portions can actively encourage a wearer to move in a specific direction and manner when performing an asymmetric motion, with this desired direction corresponding to the optimal motion of the wearer when performing the asymmetric movement. 
     In various embodiments the first and/or second materials may be selected to provide wicking-type functionality and/or cooling-type functionality. For example, the first material and/or second material can be a wicking material for promoting the wicking of moisture (e.g., sweat) away from the skin of the wearer, thereby enhancing cooling of the wearer during athletic activity. Additionally, or alternatively, one or more of the garment materials may be treated or infused with one or more materials (e.g., Xylitol) specifically designed to discharge thermal heat, control moisture and sweat, and promote the cooling of the wearer through an evaporative effect. An example material for cooling a wearer is Chill Wave from Warrior Sports, Inc. of Warren Mich. In various embodiments, one or more of the materials in the garment may be treated with an antimicrobial agent to provide antimicrobial or antifungal benefits to the garment. 
     In various embodiments of the invention, the materials constituting the garment may be connected through any appropriate means including, but not limited to, stitching and/or heat welding, bonding or seamless bonding construction. The connections between different material portions may also, or alternatively, include the use of seam tape or other separate bonding elements. In one embodiment, the first material portion and second material portion are stitched together by a flat-lock stitch. The flat-lock stitch may, for example be formed from a nylon thread. 
     One embodiment of the invention, including an asymmetric garment  100  designed to cover the upper body of a wearer, is shown in  FIGS. 2A and 2B . In this embodiment, the garment  100  includes a torso section  105 , a first sleeve  110 , and a second sleeve  115 . In various embodiments, the sleeves may be traditional sleeves or raglan sleeves. The torso section  105  includes a neck opening  120  for the wearer&#39;s neck and a torso opening  125  for a lower portion of the wearer&#39;s torso in the region of the wearer&#39;s waist. The first sleeve  110  is connected to the torso section  105  at a first end  130  thereof at the region of the shoulder of the wearer, and has an opening for the wearer&#39;s hand at a second end  135  thereof in the region of the wearer&#39;s wrist. Similarly, the second sleeve  115  is connected to the torso section  105  at a first end  140  thereof, at the region of the shoulder of the wearer, and has an opening for the wearer&#39;s hand at a second end  145  thereof in the region of the wearer&#39;s wrist. 
     The garment  100  includes a first material portion  150  which forms at least a portion of the first sleeve  110  and at least part of the torso section  105 , and a second material portion  155  which forms at least a portion of the second sleeve  115  and at least a portion of the torso section  105  proximate the second sleeve  115 . The second material portion  155  is constructed from a material adapted to provide a lesser resistance to stretching, twisting, and/or other deformation than the material forming the first material portion  150 , thereby reducing the resistance to an asymmetric shoulder and arm motion of the wearer (e.g., swinging an ice hockey stick, baseball bat, tennis racquet, etc., or throwing an object such as a baseball or football). 
     The second sleeve  115  may be formed entirely from the second material. Alternatively, only a portion of the second sleeve  115  (such as, but not limited to, the upper portion proximate the first end  140 , an inner side proximate the torso section  105 , and or an outer side away from the torso section  105 ) may be formed from the second material. An example embodiment with only a portion of the second sleeve  115  formed from the second material is shown in  FIGS. 3A and 3B . In various embodiments, the garment  100  may be long-sleeved, as shown in  FIGS. 2A to 3B , % length-sleeved, short-sleeved, as shown in  FIGS. 4A and 4B , or sleeveless, as shown in  FIGS. 5A and 5B . 
     In the embodiment of  FIGS. 2A and 2B , the second material portion  155  includes a shoulder section  160  extending over at least a portion of the front  175  and back  180  of the torso section  105 . The shoulder section  160  may be of any appropriate size and shape, and may be adapted to extend over any appropriate body portion and/or muscle group of the wearer. In various embodiments, the shoulder section  160  can extend over a greater region of the back  180  than the front  175  of the garment  100 , or vice versa. The shoulder section  160  may be shaped differently on the back  180  of the garment  100  compared to the front  175 . 
     In one embodiment of the garment  100 , as shown in  FIGS. 6A and 6B , the second material portion  155  may include a rear section  165  extending from the shoulder section  160  substantially vertically down the back  180  of the torso section  105  such that the second material extends from the neck opening  120  to the lower torso opening  125 . The rear section  165  may extend vertically, substantially vertically, or at an acute angle to the vertical plain. The rear section  165  may be formed from a single expanse of the second material or from a plurality of sections of second material. In one embodiment, the rear section  165  may include a plurality of parallel, substantially parallel, or non-parallel sections extending on the back  180  of the garment  100 . The plurality of sections forming the rear section  165  may be arranged either symmetrically or asymmetrically about a central vertical plain  185  of the garment  100 . 
     In one embodiment the rear section  165  may extend only partially down the back  180  of the garment  100 , and may extend either from the neck opening  120 , the torso opening  125 , or in an intermediate region between the neck opening  120  and the torso opening  125 . An example garment  100  having a second material portion  155  including a rear section  165  extending only partially down the back  180  of the garment  100  is shown in  FIGS. 7A and 7B . The rear section  165  may be of any appropriate width and shape. The rear section  165 , or sections, may either adjoin other sections of second material or be separate portions surrounded by first material. In one embodiment, the rear section  165  may cover the majority of, or substantially the entire, back  180  of the torso section  105 . 
     As shown in  FIGS. 6A and 6B , the second material portion  155  may also includes a side section  190  extending around at least a portion of a side  170  of the torso section  105  on the second sleeve  115  side of the garment  100 . The side section  190  extends helically downwards from the back  180  of the torso section  105  to the front  175  of the torso section  105 . The side section  190  tapers from a first width on the rear  180  of the garment  100  (where it adjoins the second material positioned on the rear  180  of the garment  100 ) to substantially a point on the front  175  of the garment  100 . 
     In an alternative embodiment, the side section  190  may taper to a different degree from a first width to a second width, be of a constant width over part or all of its full extent, or vary in width in any other appropriate manner over its extent. The side section  190  may extend at any acute angle to the horizontal plain, or may extend horizontally or substantially horizontally. In an alternative embodiment, the side section  190  can extend vertically, or substantially vertically, down one or more sides  170  of the garment  100 . The side section  190  may be of any appropriate length and width and may extend over any appropriate section of the side  170  of the torso. The side section  190 , or sections, may either adjoin other sections of second material or be separate portions surrounded by first material. The side section  190  may be formed from a single expanse of the second material or from a plurality of sections of second material. 
     In one embodiment, the side section  190  may include a plurality of parallel, substantially parallel, or non-parallel sections extending around the side of the garment  100 . An example garment having a second material portion  155  including a plurality of side sections  190  extending helically in parallel about the side  170  of the garment  100  proximate the second sleeve  115  is shown in  FIGS. 7A and 7B . 
     In one embodiment, the second material portion  155  is formed from a plurality of sections of second material connected to form a continuous expanse, as shown, for example, in  FIGS. 2A and 2B . In an alternative embodiment, the second material portion  155  is formed as a single, unitary, expanse of the second material, as shown, for example, in  FIGS. 8A and 8B . The single, unitary, expanse of the second material may, for example, be formed as a flat piece and thereafter stitched at one or more seams to form the finished section of the garment. 
     In one embodiment the second material portion  155  may include a plurality of separate portions of second material with the first material, or another material, spaced therebetween. An example garment  100  including a second material portion  155  including a plurality of spaced apart sections, with the first material  150  extending therebetween, is shown in  FIGS. 9A and 9B . Further embodiments may include a combination of separate elements, multi-sectioned elements, and/or unitary elements, depending upon the specific functionality required of the garment. 
     The second material portion  155  may be positioned only on one side of the garment  100  (i.e., extending only on, or substantially only on one side of the central vertical plain  185 ). Alternatively, the second material portion  155  may be asymmetrically arranged on both sides of the garment  100 , for example with asymmetric second material portions  155  on both shoulders and/or arms, and/or on both sides of the torso section  105 . An example embodiment having second material portions  155  extending over both sides of the garment  100  is shown in  FIGS. 10A and 10B . In this embodiment, the second material portion  155  includes a right shoulder portion  195 , a right side portion  200 , a left shoulder portion  205 , and a left side portion  210 , with the left and right sides arranged asymmetrically with respect to each other to specifically support an asymmetric motion of a wearer that includes the movement and stretching of both the left and right sides of the garment  100 . 
     In one embodiment, the second material portion  155 , or portions, may be arranged asymmetrically with respect to the front, side, and/or back of the garment  100 . An example garment  100  having a second material portion  155  arranged asymmetrically with respect to the central vertical plain  185 , and also arranged only on the side  170  and back  180  of the garment (but not on the front  175 ) is shown in  FIGS. 11A and 11B . The second material portion  155  includes a rear section  165 , a vertical side section  190 , and a shoulder section  160  extending only on the rear side of the shoulder. Here, the second material portion  155  is located only on the torso section  105 , and not on either of the sleeves ( 110 ,  115 ). In alternative embodiments, any appropriate asymmetrically sized, shaped, and located second material portion(s)  155  may be incorporated into the garment  100 , depending upon the specific athletic motion being supported. 
     In one embodiment of the invention, as shown in  FIGS. 12A and 12B , the sleeves of the garment  100  may be raglan sleeves, with a first raglan sleeve  215  formed from the first material, and a second sleeve  220 , or a portion thereof, formed from the second material, with a torso portion  225  therebetween. In an alternative embodiment, only one of the first sleeve  215  and the second sleeve  220  may be a raglan sleeve. The first raglan sleeve  215  and second sleeve  220  include a single expanse of material covering at least a portion of the arm of a wearer and extending as a single material portion from the arm of the wearer, over the shoulder of the wearer, and fully to the collar at a neck opening  120  of the garment  100 , with a diagonal seam  230  connecting the sleeve material to the torso  205  of the garment  100  and extending from the underarm to the collarbone of the garment  100 . As such, a raglan sleeve includes a single expanse of material extending over both the arm of the wearer and a shoulder portion of the torso of the wearer. In this embodiment, the second material portion  155  can form one of the raglan sleeves (e.g., the right sleeve  220  as shown in  FIGS. 12A and 12B ), or a portion thereof, and, optionally, include one or more additional sections  235  of second material extending over at least a portion of the torso portion  205 . 
       FIGS. 13A and 13B  show a garment  100  including a second material portion  155  extending over the second sleeve  115  and shoulder portion  160 , with a rear portion  250  extending down from the second sleeve  115  and forming a helically extending side portion  255  extending around the side of the torso section  105  and tapering to a point on the front  175  of the garment  100  at the torso opening  125 .  FIGS. 14A and 14B  show a garment  100  including a second material portion  155  extending over the second sleeve  115  and shoulder portion  160 , with an elongate rear portion  190  extending vertically down the rear  180  of the garment  100  from the neck opening  120  to the torso opening  125 .  FIGS. 15A and 15B  show a garment  100  including a second material portion  155  including second material extending over the second sleeve  115 , a rear portion  250  with a helically extending side portion  255 , and an elongate rear portion  190 . 
     Various other embodiments of the invention may include garments having second material portions  155  extending over any appropriate regions of the garment in any appropriate configuration, depending upon the physiology of the wearer, the specific asymmetric motion being supported, and the degree of support required. For example, one or more second material portions  155  may be positioned, in any appropriate size and shape, on regions of the upper body such as the arm, shoulder, side, chest, back, and/or waist of the athlete. 
     One embodiment of the invention, as shown in  FIGS. 16A and 16B , may include a third material portion  260  arranged on the opposite side of the garment  100  to the second material portion  155 . This third material portion  260  may be arranged in a similar configuration to the second material portion  155 , for example to provide a level of symmetry to the aesthetic look of the garment  100  and/or to provide a substantially symmetric shape to the different portions of the garment  100  to simplify manufacturing of the garment  100 . For example, the third material portion  260  may be colored to match the color of the second material portion  155  (to provide a certain degree of aesthetic symmetry to the garment  100 ), but be manufactured from a different material from the second material (thereby providing the asymmetric material properties required in certain embodiments of the invention). The third material portion  260  may be constructed, for example, from the first material, or from a material different from both the first material and the second material. 
     In the embodiment of  FIGS. 16A and 16B , the third material portion  260  includes at least a portion of the first sleeve  110 , at least a portion of the torso section  105  proximate the first sleeve  110 , a rear section  265  abutting the first sleeve  110  and extending down from the left shoulder, and a side section  270  extending helically around at least a portion of a side of the torso section proximate the first sleeve  110 . In  FIGS. 16A and 16B  the helically extending side section  270  extends over the front  175  of the garment  100  to a greater degree than the side section  255  of the second material portion  155  (i.e., it extends further towards the central vertical plain  185  of the garment  100  than the side section  255  of the second material portion  155 ), thereby providing a noticeable asymmetrical visual aspect to the garment  100 . In an alternative embodiment, the third material portion  260  may be arranged completely symmetrically with the second material portion  155  (i.e., arranged as a mirror image of the second material portion  155  on the other side of the central vertical plain  185  of the garment  100 ), or be arranged in any appropriate degree of asymmetry with the second material portion  155 . 
     In one embodiment, the third material portion  260  can be formed from a material having an intermediate degree of resistance to stretching, twisting, and/or other deformation when compared to the first material portion  150  and second material portion  155 . Alternatively, the third material portion  260  can be formed from a material having an greater or lesser degree of resistance to stretching, twisting, and/or other deformation (and/or lesser or greater coefficient of friction) than both the first material portion  150  and second material portion  155 . As a result, the third material portion  260  can be specifically designed to provide additional support to and/or control of the specific asymmetric motion being carried out by the wearer. 
     In one embodiment of the invention, as shown in  FIGS. 17A and 17B , the garment  100  includes supporting elements  300  extending over at least a portion of the shoulders of the garment. The supporting elements  300  may, for example, provide reinforcement to portions of the garment  100  that undergo significant stretching, twisting, and/or deformation during use, that are subject to significant wear during use (e.g., as they rub against protective pads or other structures or garments underlying or overlying the garment  100 ) or provide protection to various body portions of the wearer. The supporting elements  300  may be constructed the same material as either the first material or second material, or from materials such as, but not limited to, polyester blends, cotton blends or other synthetic or natural fibers. 
     In an alternative embodiment, the supporting elements  300  may be positioned over only one shoulder of the garment  100 , or may be positioned over any other appropriate position on the garment  100 , for example to support specific regions of the garment that undergo the most deformation during use and/or to overlay specific regions of the wearer&#39;s body that undergo significant wear and/or would benefit from additional protection during use (e.g., an elbow, forearm, neck, back, or chest of a garment for the upper body, or a hip, shin, thigh, knee, or rear of a garment for a lower body portion). The supporting elements  300  may be positioned on an outside surface of the garment  100 , and interior surface of the garment  100 , or between various layers of the garment  100 . Any number and/or arrangement of supporting elements  300  may be used, depending upon the specific requirements of the garment. 
     In one embodiment, the one or more supporting elements  300  may be positioned on the exterior and/or interior of the garment  100  to provide a non-slip surface on the garment  100 . This may be advantageous, for example, when the garment is to be worn under padding or other protective clothing, with the supporting elements  300  providing a non-slip surface to ensure that the padding remains in place over the garment  100 . In this embodiment, the supporting elements  300  may be manufactured from one or more polymeric elements such as, but not limited to, heat bonded material, silicone or rubber or graphic/print application. 
     In one embodiment, the garment  100  includes one or more elasticity elements  310  adapted to support a movement of the wearer during an asymmetrical athletic motion. An example garment  100  having elasticity elements  310  positioned on a front  175  thereof is shown in  FIGS. 18A and 18B . The elasticity elements  310  can be positioned on a first area of the garment  100  to store energy by elastic elongation under a first movement of a portion of the body of the wearer and to release the stored energy under a second movement of the portion of the body in an opposite direction. As a result, the elasticity elements  310  can actively store and release energy during the asymmetric movement to increase the efficiency of the movement and potentially increase the power generated by the movement. 
     The elasticity elements  310  may be positioned on the exterior and/or interior of the garment  100 , or positioned between two layers of material in the garment  100 . In one embodiment, the elasticity elements  310  may be injected into, or otherwise infused with, one or more layers of the garment  100 . In various embodiments the elasticity elements  310  may be affixed to the garment by any appropriate means such as, but not limited to, stitching, heat-bonding, chemical bonding, or by injection. 
     In various embodiments, elasticity element(s)  310  can be of any appropriate size, shape, and/or orientation depending upon the specific asymmetric motion being supported. The elasticity element(s)  310  can be positioned on the front, rear, and/or side of the garment and can overlay, underlay, or be incorporated into the first material, second material, and/or a third material. In one embodiment, the elasticity element(s)  310  can also perform the function(s) of a supporting element  300 . In an alternative embodiment, the elasticity element(s)  310  and supporting element(s)  300  are separate elements of the garment. In various embodiments the elasticity element(s)  310  and supporting element(s)  300  can be arranged either symmetrically or asymmetrically on the garment. 
     In an alternative embodiment, a second material portion may be located symmetrically on a garment, while the one or more elasticity element(s)  310  and/or supporting element(s)  300  are arranged asymmetrically. 
     Another example garment  100  incorporating an asymmetric material construction can be seen in  FIGS. 19A and 19B . In this embodiment, a second material portion  155  extends over portions of the second sleeve  115 , the second material portion  155  including a lower sleeve portion  162  separated from an upper sleeve portion  163  by an intermediate sleeve portion  164  of a separate material (e.g., a first material portion  150 ). The second material portion  155  also includes a shoulder portion  160  and a rear portion  180  forming a rear panel  182  extending over substantially all of the rear  180  of the garment  100 . In an alternative embodiment the rear panel  182  can extend over any appropriate area, and be of any appropriate shape and configuration, on the back  180  and/or front  175  of the garment  100 . The garment  100  further includes side sections  190 , with lower side panels  191  extending around both a left and right side of the torso section  105 , and an upper side panel  192  (separated from the lower side panel  191  by an intermediate side portion  193  of a different material, such as a first material portion  150 ) extending only around one side of the garment  100  on the side proximate the second sleeve  115 . 
     As discussed above, the asymmetric material construction can be integrated into any appropriate garment to support a variety of asymmetric athletic movements.  FIGS. 20A and 20B , for example, show a garment  400  comprising a pair of pants having a torso section  405 , a first leg  410  and a second leg  415 . The pants  400  include a torso opening  420  for a lower portion of the wearer&#39;s torso in the region of the wearer&#39;s waist, and further include a first leg opening  425  at a lower end of the first leg  410 , and a second leg opening  430  at the lower end of the second leg  415 . The pants further include a first material portion  150  making up a majority of the garment, with a second material portion  155  positioned at specific locations on the pants  400  to reduce the resistance by the garment to an asymmetric motion of the legs of the wearer. In the embodiment of  FIGS. 20A and 20B , the second material portion  155  includes a rear section  435  positioned on the back  440  or the pants  400  and a side section  445  positioned on an outer side  450  of the second leg  415  of the pants  400 . In this embodiment, no second material portion  155  is placed on the front  455  of the pants  400 . 
     As with the garments described above, various embodiments of garments for the lower body of a wearer may include second material portions covering any appropriate region, or regions, of the garment. In addition, garments for the lower body of a wearer may include one or more supporting element and/or elasticity element. 
     It should be understood that alternative embodiments, and/or materials used in the construction of embodiments, or alternative embodiments, are applicable to all other embodiments described herein. It should also be understood that, while many of the examples described herein show the second material portion positioned either exclusively or mainly on a right side of a garment, the invention relates equally to the positioning of second material portion on either or both or the left and right side of a garment, and/or primarily on the front or rear of the garment. 
     The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The foregoing embodiments, therefore, are to be considered in all respects illustrative rather than limiting the invention described herein. Scope of the invention is thus indicated by the appended claims, rather than by the foregoing description, and all changes that come within the meaning and range of equivalency of the claims are intended to be embraced therein.
