Tempo
Also known as: swing tempo, rhythm
Tempo is the timing relationship between the two halves of a swing — the rhythm that separates efficient, repeatable mechanics from a rushed or laboured transition.
The classic research finding in golf is that elite players share a 3:1 relationship regardless of swing speed — going back takes three times as long as coming down. Similar principles apply in tennis (preparation time vs. Contact time) and baseball (load duration vs. Contact time). It is observable from video through landmark tracking, expressed either as a proportion or as raw timings at key positions. Departures from an established personal rhythm are often the first visible sign of pressure or fatigue.
Use a simple feel cue instead of trying to count frames: say "one thousand and one" during the backswing and "hit" at impact. That phrase produces roughly the classic proportion for most beginners. Film it, compare against the measured figure, and adjust the cadence if needed.
Track it across session types: range work against on-course or pressure situations. Most players speed up measurably on course. The gap between the two is a quantifiable measure of pressure sensitivity, and targeted training reduces it.
Example
A session shows 2.4:1 on casual shots and 1.8:1 under pressure. The shortened first phase is the flag. It is visible from frame counts alone.
Why it matters
This is often the easiest variable to shift with feel cues, and it has outsized effects on consistency.
How it shows up on video
Count frames from setup to the top, then from the top to impact. Three to one, the classic golf standard, means the first phase takes three times as many frames as the second. Rushed swings land nearer 1.5:1 or 2:1. Overly deliberate ones reach 4:1 and beyond, usually losing lag and speed in the process.
Common mistakes
- Assuming slower is always better — the optimum is individual, and forcing a rhythm below your natural one disrupts the kinematic sequence rather than improving it.
- Measuring only at the range — almost everyone speeds up on course, and without that data the difference stays invisible.
- Reaching for this as a fix when the real issue is sequencing — a player who fires the arms before the shoulders strikes it poorly at any rhythm.
- Ignoring club-type differences — driver and wedge naturally differ, and comparing them without a club-specific baseline is misleading.
In SwingVantage Motion Lab
Motion Lab times this only for a golf full swing: from the start of the takeaway to the top, then from the top to impact, when the clip shows all three. Other sports, putts and chips get no tempo read yet, because it cannot tell where their backswing starts.

- 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, that pass force and speed through a swing. Each segment's energy amplifies the next.
- Consistency ScoreA consistency score measures how tightly grouped your metrics are across multiple swings — low variance produces a high score. This is because consistency is often more valuable than peak performance.
- Landmark TrackingLandmark tracking follows the position of each detected body keypoint across consecutive video frames. This creates a time-series trajectory for every joint that enables timing and velocity measurements.
