How do you know if a high jump miss was nerves or technique?
The bar coming down looks the same either way, and the difference changes what you say to the athlete next.
An athlete clears 1.55 metres clean in warm-ups, then misses 1.60 three times at the meet with what looks like the exact same approach. The easy read is that something broke technically. The harder, more common truth is that nothing did, and the athlete just jumped tight.
What "tight" looks like on film
A nervous jumper usually does not change their technique so much as change their commitment to it. The approach shortens by half a step without anyone deciding that. The plant arrives a fraction late because the last stride before it slowed down. The takeoff happens, but it happens cautiously, as if part of the athlete is bracing to miss rather than trying to clear.
Pure technical misses tend to look different. The same fault shows up in warm-ups and at the meet alike, because it was never about the moment. It was always about the movement.
How to tell them apart
- Compare the meet attempt to a warm-up clearance at the same height, side by side.
- Look at the last two steps of the approach specifically. A shortened or slowed-down approach under pressure is the clearest nerve signature there is.
- Ask what the athlete was thinking about on the runway. It sounds unscientific, and it is still more diagnostic than another rep at the same height.
If the approach and the plant look the same in both clips and the miss is still there, that is a technique question worth coaching. If they do not look the same, the fix is not a drill.
The Film Room measures hip rise, takeoff angle and knee fold and extension from the clip you give it. It has no way to measure what an athlete was feeling on the runway, and a tense approach and a technically flawed one can produce overlapping numbers. The number tells you what happened. It does not tell you why.

Why your high jumper clears 1.60 and then misses 1.65 three times
The bar went up five centimetres. Almost nothing about the jump should have changed, and a phone can show you what did.
Read →Why does my high jumper bail out at the last step instead of taking off?
A clean approach that ends in a dead stop at the bar is almost never a technique problem, which is why coaching the technique does not fix it.
Read →Why does my high jumper always miss the first attempt at a new height but clear the second?
The first jump at a new height almost never looks like the jumps that cleared the height before it, and the gap between the miss and the clear is usually small enough to film.
