Throughout this specification, unless the context requires otherwise, WO 2012/109692 PCT/AU2011/000156 5 the words "comprise", "comprises" and "comprising" will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers. 5 BRIEF DESCRIPTION OF DRAWINGS In order that the invention may be readily understood and put into practical effect, preferred embodiments will now be described by way of example with reference to the accompanying: FIG. 1A is a sectional side view of a sports ball according to an 10 embodiment of the present invention; FIG. 1B is a rear view of a bladder of the sports ball shown in FIG. 1A; FIG. 2 is a rear view of a bladder according to another preferred embodiment of the present invention FIG. 3 is an top end view of the bladder shown in FIG. 2; 15 FIG. 4 is a rear view of a bladder according to yet another preferred embodiment of the present invention; FIG. 5 is a side view of the bladder shown in FIG. 4; and FIG. 6 is a perspective view of a sports ball according to another embodiment of the present invention. 20 DETAILED DESCRIPTION OF THE INVENTION This invention relates generally to training balls and more particularly precision training sports balls for stroke training, which are constructed to create an optimal point of impact positioned strategically for the specific sport and chosen technique or method within a particular 25 sport. Therefore in one broad aspect, the invention relates to a modified sports training ball. In preferred embodiments, the invention relates to an inflatable sports ball which has particular use for kicking training. In other preferred embodiments that relate to a non-inflatable sports ball that may be used for, for example, stroke or shot training in golf. Therefore it will 30 be appreciated that a stroke is any action of hitting a ball inclusive of a hitting a ball by a body part such as a foot (such as a kick) or a hand, or hitting a ball with a sports apparatus such as a golf club, racquet and the WO 2012/109692 PCT/AU2011/000156 6 like. Reference is made to FIG. 1A being a sectional side view of an inflatable sports ball 10 according to a preferred embodiment that may be used as a training device for kicking techniques used in Australian Rules 5 Football, Rugby Union, Rugby League or American Football (otherwise known as 'NFL'). These sports game balls are of virtually the same elliptical shape but of different measurements. The inflatable sports ball 10 comprises an outer carcass 11 and a bladder 14 disposed within the interior of the outer carcass 11. The outer carcass 11 includes a durable 10 outer cover and exterior lining (not shown). It will be understood that the outer carcass 11 is manufactured from a material that is suited for the particular sports ball. By way of example, an outer carcass 11 of an NFL ball typically includes leather, although without limitation thereto. As with conventional inflatable balls, the outer carcass 11 further 15 includes a valve 12 for inflation or deflation of an inner core 15 of the bladder 14. The valve 12 is the insertion point of an inflation needle of an air pump apparatus (not shown). The valve 12 comprises a valve nipple 13a which projects out from the outer carcass 11 and acts as a stabilisation point for insertion needle. Extending from the valve nipple 20 13a and through the outer carcass 11 is the valve stem 13b which is an access guide for the insertion needle to the valve hole 13c located on the inner bladder 14. As with conventional sports ball, the valve 12 includes a soft sealing mechanism that prevents escape of air in the bladder 14 via the valve stem 13b (not shown). 25 Reference is made to FIG. 1B showing the bladder 14 of an inflatable sports ball 10 designed for training of a drop punt kick. The drop punt or pooch kick is the most accurate kick in Australian Rules Football and NFL. The drop punt is used in Australian Rules Football for goal kicking but is the least used properly and the most difficult to teach 30 correctly by coaches. For a drop punt kick, the ball is held vertically, dropped and kicked before it hits the ground thus resulting in the ball spinning backwards, end over end. This is the preferred technique for WO 2012/109692 PCT/AU2011/000156 7 goal kicking in Australian Rules Football and is more accurate and easier to mark than the punt kick, which is held flat and when kicked, spins on its horizontal axis. The bladder 14 is designed for holding pressurized air as is known 5 in the art and should be able to withstand repeated blows from a kick without rupturing or breaking loose. The bladder 14 is manufactured from or composed of a resilient material that allows energy that is introduced to the bladder 14 to be returned. It will be understood that the material from which the bladder 14 is synthesised will have elastic properties. 10 In association with the outer surface 19 of the bladder 14 are two (2) designated energy-absorbing zones 16 each in the form of a region of material such as foam, rubber, polymer-based materials or any other nominated material that is able to absorb energy as are known in the art. The thickness of the material forming the energy-absorbing zone will be 15 as required to absorb sufficient energy in the present invention. It will be understood that the designated energy-absorbing zones 16 are thus 'dead spots' on the bladder 14 which absorb the force of a kick. In alternative embodiments, the dead spots may be designed into the bladder 14, which is applicable to embodiments of the invention generally 20 this applies to the invention generally. If the bladder 14 is at least partially struck in at least one designated energy-absorbing zones 16, the ball will propel incorrectly through the air or not propel at all, which thus results in a sub-optimal outcome. Therefore, the so-called dead spots provide the user with instant feedback that an improper technique or kicking style was 25 employed.. In light of the foregoing, it will be understood that the designated energy-absorbing zones 16 may be adhered either directly or indirectly to the outer surface 19 or alternatively, may be in adhered directly or indirectly with the interior surface of the outer carcass 11. The placement of the designated energy-absorbing zones 16 in 30 association with the bladder 14 creates an optimal impact zone 18 (otherwise known as "sweet spot") for a desired kicking technique, and in this preferred embodiment a drop punt or pooch punt. Therefore it will be WO 2012/109692 PCT/AU2011/000156 8 appreciated that the sweet spot is formed from the material of the bladder or in alternative embodiments, may be formed from another material that has energy-responsive properties. With reference to FIG. 1B and in the .context of a drop punt or pooch punt, the optimal impact zone is about 5 four inches above each end point of an inflatable sports ball 10. The kicker's foot should follow through and contact the ball the optimal impact zone 18 for optimal impact and accuracy. The optimal impact zone 18 is an energy-responsive zone which allows the energy introduced into the zone to be returned (as opposed to absorbed). This return in energy 10 propels the ball away from the optimal impact zone 18 thus teaching proper technique and muscle memory and providing instant feedback for the user. Typically, although not exclusively, the optimal impact zone 18 is a region on the bladder 14 which is thus energy resilient. It will be appreciated that in other embodiments, one or more energy-responsive 15 zones may be created by application of a suitable material (other than the bladder material) that has resilience. Therefore it will be appreciated that the one or more energy-absorbing zones in combination with the one or more energy-responsive zones creates a zone of impact which, if contacted or struck, results in an optimal outcome or performance. 20 The inflatable bladder 14 thus herein described will create the normal shape of a chosen sports ball ideally without adding any weight or creation of imbalance in the ball. FIGs 2 and 3 show a bladder 20 modified according to the present invention for training of a torpedo or spiral punt. The torpedo punt, which 25 is used in American Football, is a kicking technique implemented to enhance the distance the ball is kicked. A similar but not identical technique is also used in in AFL, Rugby Union and Rugby League. The ball spins about its long axis instead of end over end (as the drop punt does), making the flight of the ball aerodynamic, but more difficult to 30 catch. With extra distance, this type of kick is also more difficult to accurately kick and judge depth. The bladder 20 includes two (2) designated energy-absorbing WO 2012/109692 PCT/AU2011/000156 9 zones 21 in association with one or more energy responsive zones in the form an optimal zone of impact for a torpedo or spiral punt 22. The optimal zone of impact for a torpedo or spiral punt 22 is typically located in the middle of the ball or slightly to the left or right of the middle if the 5 user of the sport ball is left or right footed. When a user kicks or strikes an inflatable sports ball containing the bladder 20 with the proper technique, the user's foot should come into contact with the optimal zone of impact for a torpedo or spiral punt 22 and release with the desired trajectory. If an incorrect kicking technique is used, the user's foot will at 10 least partially contact at least one designated energy-absorbing zones 21 (otherwise known as a'dead spot'), the ball will propel incorrectly through the air or not propel at all, which thus results in a sub-optimal outcome and providing the user with instant feedback that an improper technique or kicking style was employed. 15 Reference is made to FIGs 4 and 5 which show a preferred embodiment relating to training of a curve kick for use in soccer. The bladder 30 comprises a designated energy-absorbing zone 31 in combination with two energy-responsive zones in the form of an optimal zone of impact 32 (otherwise referred to as a sweet spot) for a curve kick. 20 The optimal zone of impact 32 is located on the bottom right or left on the underside of the ball when facing the direction of the target choice by user. According to this embodiment, when the user kicks the ball with proper technique for kicking a curve kick, the inside or outside foot of user should come into contact with the optimal zone of impact 32. Once 25 the foot has connected, the energy exchange between the user's foot and the optimal zone of impact 32 will result in the ball flying with near -perfection from the foot in the air. If an incorrect technique is used for the curve kick, the foot will at partially connect with the energy-absorbing zone 30 on the bladder, the ball will propel incorrectly through the air or 30 not propel at all, which thus results in a sub-optimal outcome and providing the user with instant feedback that an improper technique or kicking style was employed.

WO 2012/109692 PCT/AU2011/000156 10 Reference is made to FIG 6 which depicts a preferred embodiment of the present invention relating to a sports ball for stroke training in golf. The golf ball 40 comprises designated energy-absorbing zones 41 in combination with energy-responsive zone 42. The optimal point of impact 5 (otherwise known as a sweet spot) is in the form of the energy-responsive zone 42 which comprises two bands 43 that pass around the circumference of the golf ball 40 at right angles and intersect at two junctions 44. Preferably, the width of each band is between about 5mm and about 20mm. In preferred embodiment, the width of each band is about 10 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm and 20mm. In preferred embodiments, the designated energy-responsive zone 42 is made from normal golf ball cover material. It would be appreciated by a person of skill in the art that the ultimate aim when hitting a golf ball is that once struck, the ball flies 15 straight without going off course. When using the correct technique for chosen shot i.e driving, chipping and putting, the club will come into contact with the energy responsive zone 42 and the ball will fly off the club allowing the user to feel the ball hit the sweet spot if the user uses the wrong technique i.e dropping the shoulder, lifting their head then the club will come 20 into contact with the designated energy-absorbing zone 41 and give the user instant feedback that the proper technique was not used. It is understood that all conventional methods of manufacturing a standard sports balls to be used in their usual standard is exercised. Some of the advantages of the present invention are as follows: 25 e A sports training device that is useful for all ages and gender. * Creates muscle memory. * Provision of an inflatable training device that assists with precision training in a wide range of ball sports inclusive of soccer, American football, Australian Rules football, Rugby 30 Union and Rugby League. * The training device can be tailored for each chosen sport or chosen technique.

WO 2012/109692 PCT/AU2011/000156 11 Throughout the specification the aim has been to describe the preferred embodiments of the invention without limiting the invention to any one embodiment or specific collection of features. It will therefore be appreciated by those of skill in the art that, in light of the instant disclosure, 5 various modifications and changes can be made in the particular embodiments exemplified without departing from the scope of the present invention.
