In this episode, Henrik Jentsch—Director of the Golf Academy 360°, powered by Sportsbox AI—explores how modern biomechanics and 3D motion capture are transforming golf instruction. At the core of this revolution are two concepts: kinematics (what moves) and kinetics (why it moves). Understanding both is essential for unlocking swing efficiency and maximizing power.

Kinematics describes motion: club path, joint angles, speed, and sequencing. It's what we see when watching a golf swing. The Sportsbox 3D Golf app measures detailed kinematic parameters using just a smartphone, including:

• Chest turn

• Pelvis turn

• X-Factor

• Sway

• Lift

• Knee and elbow flexion

• Hand trajectory

These parameters help dissect movement patterns previously invisible to the naked eye. One of the most powerful tools is the kinematic sequence, which tracks how body segments (pelvis, chest, arms, club) accelerate and decelerate in a precise order, transferring energy efficiently. Sportsbox is also advancing linear kinematic sequence analysis, measuring how fast key points like the hands and clubhead move in a straight line toward the target. This has revealed unexpected truths, such as the fact that hand speed peaks before impact and then slows—contrary to many coaching assumptions.

While kinematics shows us what is happening, kinetics explains the cause. This includes:

• Ground reaction forces

• Muscle activation

• Energy transfer through the body to the club

Kinetics highlights that effective swings don’t begin with the arms—they start from the ground up. Tools like force plates have traditionally measured these forces, showing how players load, shift, and release power through their body. Kinetic data answers the critical question: where does your power really come from?

Previously, this level of analysis was limited to labs with expensive sensors and complex setups. Today, the Sportsbox 3D app removes those barriers. Using only a single smartphone camera, golfers can capture accurate 3D data anywhere—on the range or the course. This accessibility makes elite-level biomechanical feedback available to every golfer.

Henrik Jentsch emphasizes: this technology is not about creating robotic swings. It's about understanding your own unique motion—and using real data to improve it. Whether you're trying to generate more clubhead speed, fix your sequencing, or optimize energy transfer, 3D motion capture bridges the gap between feel and fact.

Kinematics and kinetics together form the foundation of modern swing analysis. One shows what’s happening; the other explains why. By combining both, coaches and players can make smarter, more targeted changes that lead to real, measurable improvement. Thanks to platforms like Sportsbox AI, this knowledge is now in every golfer’s pocket.
