Does it matter which side of the bar a high jumper approaches from?
The side of the curve is decided by which foot takes off, not by preference, and swapping it is closer to starting over than flipping a drill.
A new high jumper, or a parent watching their first meet, often asks why some athletes curve in from the left and others from the right. It looks like a style choice. It isn't.
What actually decides the side
The side of the approach is set by the takeoff foot, not the other way round. An athlete who takes off on the right foot curves in from the left of the bar, and one who takes off on the left foot curves in from the right. The curve exists to let the plant leg block and rotate the body over the bar, and that only works coming from one side for a given takeoff foot. There is no version of the flop where the takeoff foot and the approach side are independent choices.
So can an athlete switch?
Only by changing which foot they take off from, which is close to learning the jump again from the approach forward, not a quick fix for a bad meet. A handful of athletes genuinely are close to even on both feet and can carry two full approaches, but that is rare, and most of what looks like a side preference is really a takeoff-leg preference wearing a different label.
- Wind can make one side of the runway feel better, but the athlete still takes off on the same foot either way.
- Lights, a sun angle, or a crowded infield can make one side easier to sight the bar from.
- A runway that slopes or a pit set slightly off centre can genuinely favour one curve over the other, which is a venue problem, not a technique one.
What the Film Room needs from you
The high jump setting reports hip rise as a share of body height, takeoff angle, and knee fold and extension, and none of those three numbers cares which side of the bar the approach came from. What does matter is where you stand to film it. A camera on the wrong side of the curve mostly sees the athlete's back through the plant and takeoff, which is the exact moment the numbers come from. Stand on the side that keeps the plant leg and the bar in the same frame, which is the far side from the takeoff foot, not the near side.
A single 2D camera can measure the jump an athlete actually took off. It cannot tell you whether the same athlete would clear more off the other foot, because that is not a measurement question, it is a season of trying it to find out, and most coaches never have a good enough reason to spend a season on it.

Which foot should a high jumper take off from?
The foot decides which side the run starts from, and most athletes have already shown you their jumping foot somewhere other than the high jump.

Legs taking the bar after the hips have cleared is a timing fault at the top, and usually a takeoff point that drifted before it.

Some inward lean on the curve approach is correct high jump technique, the fault is starting it too many steps out, and film shows exactly when it begins.
