Why the programmes only start at fourteen
Two reasons, both practical.
First, the exercises themselves. Nordic hamstrings, single-leg jumps with added load, timed plank variations — these assume a level of core strength and body awareness that ten-year-olds usually do not have. Introduce them too early and you get poor execution, and with prevention exercises poor execution is not merely useless, it is counterproductive.
Second, the injury pattern. Children get injured differently from adolescents. The ligament and muscle injuries these programmes work against become common with puberty. Before that, contusions, fractures after falls and overload at the growth plates dominate — and no warm-up programme helps against those. Sensible load management does.
What is genuinely supported by the evidence and what gets over-quoted is covered in the evidence on injury prevention.
What matters at which age
| Age | Focus | In practice |
|---|---|---|
| Under-8s | variety | climbing, hopping, balancing, rolling. No prevention block |
| U11 | movement quality | landing, decelerating, standing on one leg — inside games |
| U13 | first structure | make the leg axis conscious, two-minute stability blocks |
| U15 | growth spurt | manage load, keep technique, take complaints seriously |
| U17 and U19 | full programme | structured warm-up programme twice a week |
The common thread: it does not begin at fourteen, it gets named at fourteen. Before that the same thing happens under a different label.
The critical phase is the growth spurt
This is the part most often underestimated in youth football. During peak growth three things happen at once:
Bones grow faster than muscles and tendons. Tendons sit under more tension, especially at their attachment. That is where the typical growth-related complaints below the kneecap and at the heel come from.
Coordination temporarily gets worse. Leverage changes faster than the nervous system recalibrates. Players who used to land safely suddenly buckle.
Load often rises at exactly that moment. Bigger players get selected more often, play for two teams, get called into representative squads. That lands on a body that is momentarily least able to take it.
What follows from that: in this phase, do not train more, train differently. Reduce jump load, listen to complaints instead of praising players through them, and rehearse landing technique as if it were new — for the body it is. More on that in growth phases in training.
Four drills for youth teams
Übung 1: Stork duel
Setup
Pairs, both on one leg, an arm's length apart.
How it runs
Using the palms only, try to push the other off balance. Whoever puts a foot down loses. Three rounds per side.
Coaching point
The knee points forward, not inward. Anyone tipping over should narrow their stance rather than push harder.
Age
From U11.
Why
It packages single-leg stability as a contest. Children do it voluntarily, and that is the condition for it happening regularly.
Übung 2: Land quietly
Setup
No equipment, firm ground.
How it runs
Land from a small step or from a jump. The task: as quietly as possible. The group listens and judges.
Coaching point
Quiet only works with bent joints and landing over the forefoot. The ear corrects better than any instruction.
Age
From U11, single-legged from U15.
Why
Landing technique is the single most effective point against knee injuries, and through volume every child understands it immediately.
Übung 3: Leg axis in the lunge
Setup
A line, enough space forward.
How it runs
Lunge forward, hold briefly, return. Ten per side. A partner stands in front and watches nothing but the knee.
Coaching point
The partner says one of two sentences: "knee over the foot" or "knee inward". Nothing else.
Age
From U13.
Why
The partner as observer is the trick. Every player gets feedback, not just the one you happen to be watching.
Übung 4: Core work as a team task
Setup
Everyone in a forearm plank, in a circle.
How it runs
In turn, each player names one item of a shared list, for instance every club in the league. Anyone who can no longer hold it cleanly stands up. Two rounds of no more than forty seconds.
Coaching point
Clean means a straight line from shoulder to heel. The moment the hips drop, it is over — do not let anyone grind it out.
Age
From U13.
Why
Core stability with a distraction, which is closer to reality than holding in silence. More formats in core training for footballers.
Load is prevention too
The most underrated lever in youth football is not the choice of exercises but the total. A U17 player who turns out for two teams, trains with a representative squad and does extra athletic work at the club quickly reaches six to eight sessions a week — plus school sport.
Three questions any coach can ask, and no programme replaces them:
How many sessions does this player actually have this week? Not with you — in total.
Is there a real break in the year? Four to six weeks without football is not a setback.
Do they still play anything else? Early specialisation in a single sport is regarded as a risk factor for overuse injuries. Doing something else alongside football until U15 costs their football nothing.
How to make it plannable
Prevention rarely fails on knowledge and almost always on consistency. Twice a week over months is the condition under which anything happens at all — and that is exactly what disappears between match preparation and pitch availability.
In Coach OS you enter age group, squad size, session times, pitch and equipment once; the prevention block is then planned into the sessions instead of being decided again every week. Behind it sit more than 1,244 animated drills, filterable by age and focus. Through Player OS, parents and players can see what is coming up.
Coach OS suggests. The coach decides. Always.
Takeaways
- Structured programmes apply from around fourteen. Before that, the same thing is built through variety and movement quality.
- The critical phase is the growth spurt: more tension on tendons, temporarily worse coordination, often more matches at the same time.
- Four drills cover the youth range, all packaged as a game or a contest.
- The biggest lever is total load across all teams, not the choice of exercises.
- Shin pads, appropriate boots and complaints that are taken seriously belong to it.
