Kinetic constrained optimization of the golf swing hub path.

Area of Science:

• Sports Biomechanics
• Kinetics and Kinematics
• Human Movement Analysis

Background:

• The golf swing involves complex interactions between the golfer and the club.
• Club head velocity at impact is a key determinant of shot distance.
• Understanding kinetic limitations is crucial for optimizing athletic performance.

Purpose of the Study:

• To optimize golf swing dynamics by manipulating hand path and club angular trajectories.
• To maximize club head velocity at impact within the golfer's kinetic limitations.
• To identify subject-specific swing modifications for improved performance.

Main Methods:

• A two-dimensional dynamic model was used to analyze typical golf swings.
• Optimization algorithms were employed to modify hand path and club trajectories.
• The study involved four subjects with varying golf swing capabilities.

Main Results:

• All subjects demonstrated the potential to increase club head velocity through trajectory modifications.
• Improvements were achieved within individual kinetic limitations (force, torque, work, power).
• Subject-dependent factors influenced the degree of velocity improvement and kinetic changes.

Conclusions:

• Modifying hand path and club trajectories enhances energy transfer to the club without increasing physical demands.
• Swing trajectory analysis can reveal a golfer's relative kinetic strengths and weaknesses.
• Personalized optimization of swing mechanics is key to maximizing club head velocity.
