Abstract
A vaulting pole apparatus having a predetermined angular displacement at an end of a vaulting pole, attributable to the vaulting pole being constructed with an inherent structural deviation located along and offset from its longitudinal axis. The vaulting pole may be constructed with a fixed structural deviation or with a removable structural deviation, wherein an end of the vaulting pole deviates or is offset from the vaulting pole's central longitudinal axis. Embodiments of this structural deviation may be fixed during vaulting by a vaulter athlete or may be adjustable by a vaulter athlete in real-time or near-real-time.
Claims22
A method for pole vaulting comprising the steps of:
- holding a vaulting pole apparatus having a substantially straight longitudinal axis and a substantially straight offset axis, configured to be compatible with physical attributes, strength and sprint speed of a vaulter athlete, said vaulter athlete endeavoring to achieve a pole vault height greater than a vault height attainable by invoking a conventional straight vaulting pole;
- sprinting down a runway while holding said vaulting pole apparatus;
- planting said vaulting pole apparatus in a takeoff box disposed at an end of said runway;
- and
- engaging in a takeoff with an implicated takeoff angle directing said vaulting pole apparatus upwardly toward a horizontal crossbar positioned at a prescribed pole vault height and disposed upon a supporting structure;
- said vaulting pole apparatus consisting of:
- a substantially linear axial portion parallel to and congruent with said longitudinal axis;
- an offset portion parallel to and congruent with said offset axis, and contiguous with and fixedly attached to said axial portion, and disposed at an acute offset angle deviating Φ° relative to said axial portion;
- and
- said takeoff angle functionally related to said acute offset angle and also selected to maximize conversion of kinetic energy engendered during said runway sprinting into potential energy stored in said axial portion of said vaulting pole apparatus during said takeoff, for enabling said vaulter athlete to vault upwardly substantially along said longitudinal axis of said vaulting pole apparatus to reach said greater vault height in excess of said preset height of said horizontal crossbar.
A vaulting pole apparatus having a substantially straight longitudinal axis and a substantially straight offset axis, configured to be compatible with physical attributes, strength and sprint speed of a vaulter athlete, said vaulter athlete endeavoring to achieve a pole vault height greater than a vault height attainable by invoking a conventional straight vaulting pole and by vaulting with a pole having greater length and greater stiffness than the length and stiffness of said conventional straight vaulting pole, and involving sequence of steps of sprinting down a runway while holding said vaulting pole apparatus, planting said vaulting pole apparatus in a takeoff box disposed at an end of said runway, and engaging in a takeoff with an implicated takeoff angle directing said vaulting pole apparatus upwardly toward a horizontal crossbar positioned at a prescribed pole vault height and disposed upon a supporting structure, said vaulting pole apparatus consisting of:
- a substantially linear axial portion parallel to and congruent with said longitudinal axis;
- an offset portion parallel to and congruent with said offset axis, and contiguous with and fixedly attached to said axial portion, and disposed at an acute offset angle deviating Φ° relative to said axial portion;
- and
- said takeoff angle functionally related to said acute offset angle and also selected to maximize said length and said stiffness of said linear axial portion of said vaulting pole apparatus commensurate with said physical attributes and said strength of said vaulter athlete, for enabling said vaulter athlete to vault upwardly substantially along said longitudinal axis of said vaulting pole apparatus to reach said greater vault height in excess of said preset height of said horizontal crossbar.
