What the broad jump measures

A vertical jump shows how much force you can put into the ground straight down. A broad jump asks for the same maximal effort at an angle, so the hips and legs have to drive the body forward as well as up, which is the direction rugby actually uses in the first strides of a sprint and in the leg drive into contact. The jump is not a barbell score in disguise either: when a national sevens squad was profiled across the gym and the jumps, bench press, back squat, and isometric pull results tracked the countermovement jump and push up force scores but not long jump distance, so the broad jump picks up a quality the strength numbers alone do not show.

What measured rugby squads actually jump

The distances below come from two cohorts tested with a tape measure and the best of three attempts counted. The sevens players were men in their early twenties in a national squad, jumping with an arm swing into a long jump pit. The schoolboys were fifteen rugby union players from one school's senior development squad, average age just under seventeen, jumping from a line and sticking the landing.

Tracking it over a season

The test repeats well when the setup stays frozen. The sevens squad tested twice, a week apart, and the threshold for a genuinely real change came out at roughly ten centimetres on a best jump, and about seven when the three attempts were averaged, so the average of three is the steadier number to log. Anything inside a few centimetres between sessions is normal wobble, and a gain only counts once it clears that noise band and holds.

Distance responds to training, too. The schoolboy squad averaged 1.89 m before a six week block that combined plyometric and resistance sessions, and 1.97 m four weeks after the block ended, with the gain landing during those final weeks of continued resistance and rugby training.
