Which term describes the method used to analyze the efficiency of body movement in the golf swing?

• A. Ball flight analysis
• B. Ground force measurement
• C. 3D Motion Analysis
• D. Swing tempo analysis

Answer: (C)

Analyzing how efficiently the body moves in a golf swing relies on capturing the actual motion of the entire body in three dimensions. 3D Motion Analysis does this by tracking markers or sensors placed on the body to measure how each segment moves through space, giving joint angles, velocities, accelerations, and timing. With this data, you can see how well the hips, torso, arms, and wrists coordinate to transfer energy toward the club, identify wasted movements, and compare different swings or athletes.

Ball flight analysis looks at the ball’s trajectory and outcome, not the movement pattern that produced it. Ground force measurement records the forces between the feet and ground, which helps understand load and power generation but doesn’t map the body’s movement itself. Swing tempo analysis focuses on the rhythm and timing of the swing rather than the complete 3D motion of the body. Therefore, the method that best analyzes the efficiency of body movement is 3D Motion Analysis.
