How do you know a thrower is ready for full-effort throws after a back strain?

A thrower who says they feel fine is not the same test as a trunk that actually moves the way it did before the injury.

Back strains are common in the rotational throws, shot, discus and javelin all load the trunk hard through a quick turn, and a coach bringing a thrower back from one faces a real problem: the athlete reports no pain, but a half-speed throw in practice and a full-effort throw in competition load the trunk in completely different ways. Pain-free at half speed proves very little about full speed.

A practical ladder back up

• Standing throws with no wind-up first, which isolates the release itself from the rotation that caused the injury.
• A slow wind-up at reduced effort next, once standing throws feel and look normal across more than one session, not just one good rep.
• Full approach or full spin last, and only once both earlier steps have held up repeatedly, not once.

What the Film Room actually adds here

The throws setting reads release angle and whether the trunk stays tall over the drive leg rather than collapsing. That trunk number is not signed to a direction, which sounds like a limitation, and for most throwing questions it is one. For this particular question it is almost beside the point: what a coach watching a return from injury wants is not which way the trunk leans, but whether it collapses by the same amount, at the same point in the throw, that it did before the injury. A plain magnitude, read the same way on a clip from before the injury and a clip now, answers that without needing to know which direction is which.

A camera reads motion, not tissue. It cannot tell you whether the strain has actually healed, whether there is still swelling, or what an MRI would show. The mechanics number is only worth watching once a medical professional has already cleared the athlete for full effort, and it should never be the thing that makes that call instead.
