Abstract
- This study analyzed the fundamental geometric and kinematic
characteristics of the swing hub path of the golf shot for four
diverse subjects. In addition, the role of the hub path geometry
in transferring the kinetic quantities from the golfer to the club
were investigated. The hub path was found to have a complex
geometry with significantly changing radii, and a constantly
moving center-of-curvature during the downswing for all subjects.
While the size and shape of the hub path differed considerably
among the subjects, a three phase radius-based pattern
was revealed that aligned with distinct stages of the downswing.
Artificially controlling and optimizing the hub path of the better
golfer in the group indicated that a non-circular hub path was
superior to a constant radius path in minimizing the kinetic
loading while generating the highest possible club head velocity.
The shape and purpose of the hub path geometry appears to
result from a complex combination of achieving equilibrium
between the golfer and the club, and a purposeful configuring of
the path to control the outward movement of the club while
minimizing the kinetic loading on the golfer yet transferring the
maximum kinetic quantities to the club. Describing the downswing
relative to the hub path phasing is presented and was
found to be informative since the phases align with significant
swing, kinetic and kinematic markers. These findings challenge
golf swing modeling methodologies which fix the center-of-curvature
of the hub path thus constraining it to constant radius
motion.
