A swing segment can move in six ways
Sportsbox describes motion with six degrees of freedom: three linear movements and three angular movements.
The linear movements are sway, lift, and thrust—side to side, up and down, and forward and backward. They are measured as distance.
The angular movements are turn, bend, and side bend. They describe orientation and are measured in degrees.
Together, these movements explain how a segment such as the chest or pelvis changes position and orientation during the swing.
Use the framework to narrow the observation
A video observation such as “the hips move too much” is not yet a precise measurement question. The six-degree framework helps separate what the coach may be seeing.
Is the pelvis moving toward the target through sway? Is it moving toward the ball through thrust? Is it rising through lift? Is its orientation changing through turn, bend, or side bend?
The goal is not to display all six measurements at once. It is to identify the smallest set that can test the coaching hypothesis.
Pair position with orientation
Two swings can look similar from one camera view while differing in 3D. A segment can change its location and its orientation at the same time.
For example, the pelvis can turn while also swaying, thrusting, or lifting relative to address. Reading the relevant Trackers together creates a more complete description than relying on one two-dimensional position.
Finish with one measurable intervention
Once the movement question is clear, choose the Tracker that best represents it and an Indicator at the swing event that matters. Explain the movement in plain language, apply the coaching intervention, and re-measure the same data.
The framework is most useful when it reduces complexity: observe, classify the movement, test it, and give the golfer one clear priority.
