Why does my long jumper look off balance right before the board?
The wobble usually starts two strides before the board, not on it, and the Film Room can show you exactly where.
The approach looks fast and rhythmic for the first ten strides, then something changes in the last three. The shoulders rock, the head drops, and the athlete arrives at the board looking like they are fighting to stay upright rather than gathering to jump.
The board does not cause this, the approach does
A long jump approach is built to end in one accurate step onto a board roughly 20cm wide, and that accuracy gets harder to hold the faster the athlete is moving. Most of what looks like a balance problem at the board is really the trunk and arms compensating for something that went slightly wrong two or three strides earlier, usually a check in stride length as the athlete starts hunting for the board with their eyes instead of trusting steps they have already rehearsed.
What usually causes the search
- Looking down at the board too early, which pulls the head and shoulders forward and disturbs the rhythm before the plant.
- A run-up that has never been measured and marked, so the athlete is guessing at the last few strides instead of repeating a checked pattern.
- Arms working independently of the legs in the last two strides, which shows up as a wide or uneven swing right when the body most needs them driving straight ahead.
The fix is almost never at the board. It is teaching the approach to be the same length every time, marking a checkpoint six or seven strides out, and trusting that mark rather than adjusting stride length by eye in the last three steps.
What the Film Room actually reports
The long jump setting reads takeoff angle against the usual 18 to 22 degree band, hip rise as a share of body height, and trunk and arms through the approach. That third one is the number for this problem. It will not hand you a named drill the way takeoff angle does, because a wobble in the arms two strides out does not have one threshold that is right for every athlete. What it gives you instead is the shape of the approach, frame by frame, so you can see exactly where the wobble starts.
A camera filming the whole runway will show the wobble but not the checkpoint itself unless it is in frame. Mark the check before you film, and set the camera wide enough to catch the last eight strides, not just the board.

Why your long jumper keeps fouling
Three red flags in a row is rarely carelessness at the board. It is a run-up that was never the same length twice.
Read →How long should a long jump run-up be?
Long enough to reach the speed the athlete can still take off from, and not one stride longer.
Read →Why does my long jumper land shorter than their speed says they should?
A fast approach and a short landing usually means the speed never converted at the board, not that the athlete stopped being fast.
