Protect your shoulder and knee in handball: prevention programs cut injury risk measurably. Train external rotators, tackle GIRD and land safely.
## Introduction "Can I even protect my shoulder and knee in handball — or is it down to luck?" — the honest answer: it's not luck, it's training. Your two weak spots are the thrower's shoulder and the knee, and those are exactly what you can shore up on purpose. With structured prevention programs you cut your shoulder injury risk by around 40 % (odds ratio 0.60) and your knee risk by almost half (OR 0.53). Ten to fifteen minutes per session is enough to lower your risk measurably.
Why it matters so much: 17 to 41 % of handball players have shoulder problems over the course of a season. And ACL ruptures hit even professionals regularly — around 0.044 ACL injuries per 1000 hours of handball in men, mostly without opponent contact during landing or change of direction. The good news: a controlled prevention program cut severe acute knee injuries from 0.348 to 0.059 per 1000 hours — over 80 % fewer. Prevention works if you do it consistently.
## What You Need - A resistance band for the shoulder external rotators. - Some space for balance and jump drills; optionally a wobble board or balance pad. - 10–15 minutes per session, 2–3 times per week. - An honest self-assessment of your shoulder mobility, side to side. - Optional: a coach or physio for a quick GIRD check.
### 1. Why Is the Shoulder So Vulnerable? Strengthen the External Rotators Through thousands of throws, handball players' internal shoulder rotators dominate. Weakness of the external rotators is one of the best-documented risk factors for shoulder injuries. So train the external rotators 2–3 times per week, with an eccentric emphasis (slow release against the band). Three sets of 12–15 clean, controlled reps are enough. This centers the humeral head and protects the tendons — right where the one-sided throwing load leaves its mark.
### 2. Spot and Stop GIRD GIRD (glenohumeral internal rotation deficit) is a loss of internal rotation in the throwing shoulder — it rotates inward clearly worse than the other side. Check your rotation side to side; as a practical rule of thumb a difference over 20° is a warning sign. Stretch the posterior shoulder capsule consistently, for example with the sleeper stretch.
### 3. Train Landing and Cutting (Knee/ACL) Most ACL ruptures happen without contact during landing or an abrupt change of direction. So deliberately practice the soft landing: on both legs, hips and knees bent, knees over the toes (no knock-knee). Regularly include jump-landing drills and cutting exercises with clean technique — these are exactly the components that make prevention programs work. The same clean landing technique also protects your ankle, whose injury risk structured programs likewise reduce substantially (OR 0.57).
### 4. Balance and Proprioception Under Fatigue Fatigue degrades neuromuscular control and therefore throwing and landing quality — especially in the jump shot. That is why balance and stability drills (single-leg stance, single-leg landings, wobble board) belong deliberately at the end of training, when you are tired. That is exactly when injuries happen in a match.
### 5. Whole-Body Instead of an Isolated Fix Prevention programs work best when they combine technique education, balance, jump/landing training and strength. Whole-body programs even help the shoulder — via the kinetic chain. The reason: a powerful, well-timed pelvic and trunk rotation unloads the elbow and shoulder during the throw and reduces valgus stress. Make the program a fixed part of your warm-up, not an optional extra — and keep it up all year, not just until the first complaints fade.
## Common Mistakes - Training only internal rotators and bench press: amplifies the imbalance. Fix: add targeted external rotator work. - Prevention only once it already hurts: too late. Fix: year-round and preventive. - A stiff, straight-legged landing: the main ACL risk. Fix: soft, knees bent. - Balance drills only when fresh: Fix: deliberately also under fatigue. - Ignoring GIRD: Fix: check mobility regularly side to side.
## Safety Notes Prevention does not replace treatment. With acute pain, a feeling of instability in the knee, a "pop" with swelling, or persistent shoulder pain, you belong with a doctor or physiotherapist — not back on the court. Progress new exercises slowly and pain-free. Fingers and hands are also exposed in handball: tape an unstable finger joint for games and train your catching technique instead of blocking balls. A prevention program shows effect over weeks — the studies ran around 8 months on average. Stay with it, even when nothing hurts.
## Pro Tip Anchor your prevention program firmly to an existing fixed point: do the band work for the external rotators always right before your first throw in the warm-up, and the landing drills always at the end. Whatever is tied to a fixed routine actually gets done — and consistency is the only factor that truly counts in prevention.
### Do prevention programs in handball really work? Yes, clearly. A meta-analysis of 9 studies with over 7000 players shows: shoulder risk drops by around 40 % (OR 0.60), knee risk by almost half (OR 0.53), ACL injuries by a third (OR 0.66) and ankle injuries similarly (OR 0.57). The prerequisite is regular execution over months.
### What exactly is the thrower's shoulder (GIRD)? GIRD stands for glenohumeral internal rotation deficit — the throwing shoulder loses internal-rotation mobility compared to the other side. Due to the one-sided throwing load the posterior capsule shortens and the internal rotators dominate. This is considered a risk factor for shoulder complaints. The remedy: strengthen the external rotators and stretch the posterior capsule.
### Which injuries are most common in handball? Most often it hits the lower extremity — thigh, knee and ankle — plus the shoulder as the upper-extremity hotspot. Far more happens in competition than in training. Acute injuries such as contusions and sprains dominate, alongside overuse damage mainly at the throwing shoulder.
### How do I best protect my ACL? Train landing and change of direction deliberately: on both legs, soft, knees bent and over the toes. Add balance and jump-strength exercises, ideally under fatigue. A structured program cut severe knee injuries by over 80 % — that is exactly what you should model yourself on.
