Jump Injury Prevention & Rehab Guide
Why jumpers get injured, the load-capacity rule, the four most common injuries, good vs bad pain and a safe return ladder.
Jump training loads tendons, bones and joints harder than almost any other activity. Most injuries are not accidents — they are load-management failures, which means they are largely preventable.
Why jumpers get injured
The patellar tendon takes 8–12x bodyweight per jump, the Achilles is loaded heavily on every push-off, and ankle sprains happen when proprioception lags behind returning to play. The common thread is load outrunning capacity.
The load-capacity rule
Increase weekly jump volume by no more than 10%, progress plyometric intensity in ladders, and remember that tendons adapt slower than muscle. When pain appears, adjust load first — rest alone lowers capacity further.
Patellar tendon (jumper's knee)
Prevention: gradual volume, posterior-chain strength, isometric prehab (wall sits 3×45s). Rehab: isometrics first for pain, then decline-board eccentrics, then reloading — with pain kept at or below 3–4/10.
Achilles
Prevention: volume control, isometric peak holds, slow eccentrics, ankle mobility. Warning signs: morning stiffness over 30 minutes, mid-tendon thickening. A sudden 'kicked in the heel' with a gap is an emergency.
Ankle sprains
Return by function, not the calendar: single-leg balance, 15 pain-free calf raises, stable hops, and a Y-Balance difference under 4 cm. Early return multiplies re-sprain risk about five-fold.
Shin splints (MTSS)
Cut volume, substitute low-impact work, strengthen the anterior shin and arch. Return at 50% volume with +10% per week maximum; pain persisting 2 weeks after rest needs a doctor to rule out a stress fracture.
Good vs bad pain and the return ladder
Symmetric muscle soreness that fades with warm-up is DOMS; sharp, unilateral, joint-level or movement-changing pain is a stop signal. Return to jumping through a ladder — pogo, low box, depth drop, depth jump — advancing only when each step is pain-free and fearless.
Key takeaways
- Volume jumps of ≤10% per week protect every tendon and bone.
- Tendons adapt slower than muscle — load progressively.
- Rehab with pain at or below 3–4/10; judge it the next morning too.
- Return from ankle injury by function, not time.
- Any pain that changes your movement pattern means stop.
