Elite golf swings begin from the ground up. In Part 4 of our 10-part biomechanics series, we explore how the lower body creates power through efficient ground reaction forces (GRFs), pelvic rotation, and proximal-to-distal sequencing. Rather than relying on timing with the hands, elite golfers generate speed by transferring energy from the ground through the pelvis, torso, arms, and finally the club.
Using research from Butler (2019), Lynn et al. (2013), and Athletic Motion Golf, we examine how the Center of Pressure (CoP) shifts during the swing. During the backswing, pressure moves into the trail foot. In transition, force rapidly shifts into the lead leg, creating the rotational torque required for maximum clubhead speed.
Pelvic acceleration is one of the strongest predictors of performance. Elite golfers reach peak pelvic speed approximately 100 milliseconds before impact, allowing energy to flow efficiently into the torso, arms, and club while improving Smash Factor and consistency.
A key movement is the "Knee Switch." The lead knee flexes while the trail knee extends slightly, creating pelvic inclination that allows efficient hip rotation without losing posture. This movement loads the glutes, improves sequencing, and produces the powerful "whip effect" seen in elite players.
Research also shows the physical demands placed on the body. Hip joints experience forces of around 3× body weight, while knee joints can exceed 4× body weight, making efficient sequencing essential for both performance and injury prevention.
Common faults include locking the trail knee, early extension, poor pelvic tilt, and excessive lateral sway. These errors reduce rotational efficiency, disrupt sequencing, and force golfers to compensate with their hands through impact.
Key Takeaways
Generate power from the ground, not the arms.
Maintain a dynamic trail knee throughout the swing.
Create pelvic acceleration early in transition.
Separate the pelvis from the upper body for an efficient kinetic chain.
Proper sequencing increases speed, consistency, and reduces joint stress.
Mastering lower-limb biomechanics provides the foundation for longer, more consistent golf shots and a more efficient, repeatable golf swing.
