Tempo
Also known as: swing tempo, rhythm
Tempo is the timing ratio between the backswing and downswing — the rhythmic pattern that separates efficient, repeatable mechanics from a rushed or overly slow transition.
In golf, the classic research finding is that elite players share a 3:1 backswing-to-downswing tempo ratio regardless of swing speed — the backswing takes three times longer than the downswing. Similar principles apply in tennis (preparation time vs. contact time) and baseball (load duration vs. contact time). Tempo is observable from video via landmark tracking and is expressed as a ratio or as timing values at key positions. Deviations from a player's established tempo pattern are often the first sign of swing pressure or fatigue.
Example
A golfer's session shows a 2.4:1 tempo ratio on casual shots but 1.8:1 under pressure — the shortened backswing is the rush flag, detectable from frame counts.
Why it matters
Tempo is often the easiest swing variable to change with feel cues, and it has outsized effects on consistency and timing.

- Movement SequencingMovement sequencing is the timed order in which body segments accelerate and decelerate through a swing — correct sequencing multiplies speed; incorrect sequencing bleeds it.
- Kinematic ChainThe kinematic chain is the sequence of body segments — from ground to tip — through which force and speed are transferred in a swing, with each segment's energy amplifying the next.
- Consistency ScoreA consistency score measures how tightly grouped your metrics are across multiple swings — low variance produces a high score, because consistency is often more valuable than peak performance.
- Landmark TrackingLandmark tracking follows the position of each detected body keypoint across consecutive video frames, creating a time-series trajectory for every joint that enables timing and velocity measurements.
