Golf training system and methods
A golf training system generally includes a photoluminescent light-reactive surface and a light source that is placed on a golf club. During a training stroke performed over the photoluminescent surface, the light source excites phosphors in the light-reactive surface during a stroke and in doing so creates a transient visible “record” of the precise track the club head makes during the stroke. In some embodiments, the system can include a training ball having a phosphorescent material affixed to or integrated into the surface of the ball so that a light source placed on the golf club excites the phosphorescent material and indicates the point of contact between the golf club and the training ball.
1 . A training ball comprising:
a ball having a surface; and
a phosphorescent material comprising SrAl 2 O x green :Eu 2+ , Dy 3+ , B, or any combination thereof, affixed to or integrated into the surface of the ball, the phosphorescent material selected to produce a phosphorescent signal when exposed to light from a light source, the phosphorescent signal having a duration of from one second to 60 seconds.
2 . A golf training system comprising:
a light source attached to a golf club;
the training ball of claim 1 ; and
a phosphorescent substrate positioned beneath the light source and golf club, the phosphorescent substrate selected to produce a phosphorescent signal when exposed to light from the light source, the phosphorescent signal having a duration of from one second to 60 seconds.
3 . The golf training system of claim 2 , wherein the light source emits light having a wavelength of from 200 nm to 410 nm.
4 . The golf training system of claim 2 , wherein:
the light source comprises a distal end;
the golf club comprises a club head having a sole; and
the distal end of the light source is 1 cm to 150 cm from the sole of the golf club.
5 . A method of recording a swing path, the method comprising:
providing the golf training system of claim 2 ; and
performing a training stroke having a swing path so that light emitted from the light source excites the phosphorescent substrate, thereby producing a transient phosphorescent signal that records the swing path.
6 . The method of claim 5 , wherein the transient phosphorescent signal has a duration of from one second to 60 seconds.
7 . The method of claim 5 , wherein the transient phosphorescent signal is visible with no additional components.
8 . The training ball of claim 1 , wherein the phosphorescent signal is visible with no additional components.
9 . A method of recording a point of contact between a golf club and a training ball, the method comprising:
providing a golf training system comprising:
a golf club comprising a club head; and
a light source attached to golf club;
providing the training ball of claim 1 ; and
performing a training stroke such that the club head contacts at least a portion of the surface of the training ball so that light emitted from the light source excites the phosphorescent material on the training ball and produces the transient phosphorescent signal at the point of contact between the club head and the training ball.
10 . The method of claim 9 , wherein the phosphorescent signal is visible with no additional components.
11 . The training ball of claim 1 , wherein the phosphorescent material is affixed to or integrated into a portion of the surface of the ball.
12 . A method of simultaneously recording a training golf swing path and a point of contact between a golf club and a training ball, the method comprising:
providing a golf training system comprising:
a golf club comprising a club head;
a light source attached the golf club; and
a phosphorescent substrate positioned beneath the light source and golf club, the phosphorescent substrate selected to produce a first phosphorescent signal when exposed to light from the light source;
providing the training ball of claim 1 ; and
performing a training stroke having a swing path wherein the club head contacts at least a portion of the surface of the training ball so that light emitted from the light source excites both the phosphorescent substrate and the phosphorescent material of the training ball, thereby producing the first phosphorescent signal that records the swing path and the second phosphorescent signal at the point of contact between a golf club and a training ball.
13 . The method of claim 12 , wherein the first phosphorescent signal has a duration of from one second to 60 seconds.
14 . The method of claim 12 , wherein the second phosphorescent signal has a duration of from one second to 60 seconds.
15 . The method of claim 12 , wherein the first phosphorescent signal and the second phosphorescent signal are visible with no additional components.
