Vault has more jargon per minute than any event on the track. A coach will tell a first-year athlete their step is under, their block collapsed, and they need to get off the runway before the clock kills the trial, and none of that is English yet. The table below defines every term a new vaulter runs into in their first season, with the legal dimensions where the rulebook actually specifies one. Several of these terms have a full page of their own on this site, and those are flagged in the notes underneath.
Box, standards, crossbar, pit, and zero line are the five words that make a coach's instructions parse. They are also the ones with exact legal dimensions, which means there is one right answer rather than a coaching opinion. Our pages on what the box is in pole vault and on pole vault pit dimensions carry the full spec if you need the numbers for a facility check.
Plant, swing-up, turn, and blocking describe the same jump from four coaching traditions, and different clubs use them slightly differently. Do not treat any one definition as gospel. If your coach's version of the swing-up sounds unlike the one below, theirs is the one that matters for your jump. The pole vault plant page and the pole vault swing-up page go deeper on each.
Flex number, weight rating, grip height, and pole length interact, and getting them wrong is how vaulters end up on poles they cannot bend or poles they blow straight through. The pole vault flex number explained page covers stiffness ratings properly, and the pole weight explained page covers what the printed number on the pole actually promises.
Half of learning the vault is matching the word your coach says to the thing your body did. Film one attempt and the AI labels the phases for you, so the next time someone says your swing is late you already know which frame they mean.

Legal dimensions come from the World Athletics Technical Rules. Coaching terms are given in their most common US usage, and some clubs use them differently.
| Term | What it means |
|---|---|
| Approach | The run-up. Counted in strides, from about 6 for a beginner to 18 to 22 for an elite vaulter, over a runway of at least 40 m. |
| Bail | Letting go of the pole or pulling off at takeoff instead of committing. Almost always a setup problem rather than a nerve problem. |
| Blocking | Keeping a firm bottom arm at takeoff so the pole bends against it instead of folding your shoulders back. Also called the bottom-arm block. |
| Blow-through | Getting through the pole so easily that you land deep and flat with nothing left to push off. A sign you have outgrown the pole. |
| Box | The metal-lined slot the pole tip drops into. 1.00 m long, 0.60 m wide at the front, tapering to 0.15 m at the stop board, with a 105 degree angle between base and stop board and a base 0.20 m below runway level at the back. |
| Box collar | Padding placed around the box. World Athletics lets an athlete set their own padding around the box within the time allowed for their trial. |
| Bubble | An air-supported dome. For a lot of US vaulters it is where the whole winter happens. On a meet sheet, being on the bubble instead means sitting right at a qualifying cutoff. |
| Bungee | An elastic cord used in place of a crossbar in practice so you can jump at height without stopping to reset a bar. |
| Countback | The tie-break procedure. Fewest misses at the tied height first, then fewest total misses. |
| Crossbar | 4.50 m plus or minus 0.02 m long for the vault, no more than 2.25 kg, 30 mm across, resting on pegs set 4.28 m to 4.37 m apart. |
| Drive knee | The knee of the free leg, driven up and forward at takeoff to start the swing. |
| Flex number | A stiffness rating within a pole's weight rating. A lower flex number means a stiffer pole. Two poles of the same length and rating can feel very different. |
| Grip height | How far up the pole your top hand sits, measured from the tip. The number that most predicts the height you can clear. |
| Mid mark | A check mark partway down the runway, commonly at 6 steps out, that a coach watches to judge whether the approach is on before you ever reach the box. |
| No-height | Written NH. No clearance at any height attempted, so no mark goes on the sheet at all. |
| Pass | Declining an attempt at a height. Once you have passed a trial at a height you cannot come back to it, except in a jump-off for first place. |
| Penetration | How far past the box you travel. Poor penetration means landing short, near the front of the pit or back toward the box. |
| Pit | The landing area. For top-tier World Athletics competition it is at least 6 m long behind the zero line by 6 m wide by 0.8 m high, with front pieces at least 2 m long. |
| Plant | Driving both hands overhead while the tip drops into the box. It should be finished before the takeoff foot lands. |
| Pole rating | The weight printed on the pole. Vaulting on a pole rated below your body weight is the classic route to breaking one. |
| Run-through | Aborting the approach without planting. Legal, but the clock keeps running and a trial that times out is scored as a failure. |
| Stalling out | Failing to rotate the pole to vertical, so you come down in front of the bar instead of over it. |
| Standards | The uprights holding the crossbar. You choose where they sit, anywhere from directly above the back of the box out to 80 cm toward the landing area, and you tell the official before your trial. |
| Step | Your takeoff distance from the back of the box. A step that is under means you took off too close to the box. |
| Swing-up | Whipping the trail leg and hips up toward the top hand after takeoff. The engine of the whole vault. |
| Top hand | The upper hand on the pole. It sets your grip. Once you leave the ground you may not slide it higher or bring the lower hand above it. |
| Turn | Rotating to face the bar as the pole straightens and the hips pass over the head. |
| Volzing | Pushing the bar back onto the pegs with a hand during clearance, named for Dave Volz. It is a failure under the current rules, which count steadying or replacing the bar by hand as a miss. |
| Zero line | The line drawn across the runway in line with the back of the box. Standards settings and takeoff distances are both measured from it. |
