The FIFA 11 might be insufficient
Why we need to rethink ACL injury prevention in today’s youth athletes
For over a decade, the FIFA 11+ has been one of the most widely promoted injury prevention programs in female soccer.
Early research showed meaningful reductions in injury rates, particularly for lower extremity injuries and ACL tears. Teams that actually adhered to the program saw benefits. That matters.
But here’s the truth:
The FIFA 11+ was built for a different athlete, in a different era.
And if we’re being honest about what youth sport looks like today, it’s no longer enough.
The Original Promise of the FIFA 11+
The FIFA 11+ was designed as a structured warm-up program to improve:
Neuromuscular control
Balance and coordination
Strength (particularly lower body and trunk)
Movement mechanics (landing, cutting, deceleration)
It was simple, scalable, and required minimal equipment. That’s exactly why it gained traction.
From a public health standpoint, it made sense:
“If we can give teams a plug-and-play warm-up, we can reduce injuries without needing full S&C infrastructure.”
And again—it worked in the context it was created for.
Problem #1: The Research Is Now Outdated
Most of the foundational FIFA 11+ studies are now 10–15+ years old.
Because research doesn’t exist in a vacuum—it reflects the population, environment, and sport culture at the time.
And youth sport has changed dramatically since then:
Earlier specialization
Higher training volumes at younger ages
More year-round competition
Less unstructured play
Declines in general physical literacy
So when we say “the FIFA 11+ reduces ACL injury risk,” we need to ask:
In who? Under what conditions? Compared to what baseline?
Because today’s athlete is not the same as the athlete from 2008. I know this because I have been working in high performance since 1998 where females could bang off 35 push-ups.
Problem #2: It Assumes a Base That No Longer Exists
The FIFA 11+ was never meant to build athletes from scratch.
It was designed to enhance and reinforce movement quality—not create it.
But here’s the issue: Many youth athletes today don’t have the foundational movement competency the program assumes.
We’re seeing athletes who struggle with:
Basic coordination
Deceleration control
Single-leg stability
Force absorption
Spatial awareness
These are not “high-performance problems.”
These are developmental gaps.
And a 15–20 minute warm-up—even a well-designed one—cannot compensate for years of missing physical development.
Problem #3: Warm-Up ≠ Preparation
A warm-up is not a training program.
The FIFA 11+ lives in the warm-up space. That means:
Low load
Limited progression
Minimal individualization
Constrained intensity
That’s not where meaningful strength, power, or tissue capacity is built.
ACL injury risk is strongly tied to:
Eccentric strength
Rate of force development
Braking capacity
Force attenuation strategies
You don’t meaningfully develop those qualities with:
Bodyweight squats
Basic hopping drills
Low-level balance tasks
Especially not in athletes who are already underprepared.
Problem #4: It Doesn’t Address the Real Driver—Load vs Capacity
Injury risk is not just about movement quality.
It’s about the relationship between:
What the athlete is asked to do (load)
vs
What the athlete is prepared to tolerate (capacity)
The FIFA 11+ focuses heavily on movement patterns, but does very little to build:
Robust strength
Tendon stiffness
High-force eccentric control
Repeated sprint and deceleration capacity
So what happens?
Athletes complete the warm-up…
Then enter a game environment that far exceeds their physical capacity.
That’s where injuries occur.
Problem #5: It Ignores Overspecialization
This is the big one.
The FIFA 11+ was developed in a time when youth athletes were still:
Playing multiple sports
Developing broad movement skills
Accumulating varied physical experiences
Today?
We see:
10–12 year olds specializing
Year-round competition schedules
Skill repetition without physical development
Minimal exposure to jumping, sprinting, or strength training outside sport
So now we’re trying to “injury-proof” athletes who:
Lack general strength
Lack movement variability
Lack physical resilience
And we’re doing it with a warm-up? That’s not a solution or even a plan.
So What Should We Be Doing Instead?
If we’re serious about ACL injury prevention, we need to zoom out.
This is not a warm-up problem.
This is a development problem.
1. Build Physical Literacy First
Before we talk about ACL prevention, athletes should be competent in:
Landing and absorbing force
Decelerating under control
Changing direction with intent
Producing and reducing force
This is foundational.
2. Strength Training Is Not Optional
You cannot prevent knee injuries without building:
Eccentric strength (especially quads and hamstrings)
Hip and trunk control under load
Single-leg strength and stability
This requires progressive overload, not just movement drills.
3. Train the “Brakes,” Not Just the “Engine”
Most ACL injuries occur during:
Deceleration
Cutting
Landing
We need to train:
Braking mechanics
Force absorption strategies
High-speed deceleration
Not just linear running and light hops.
4. Individualize Where It Matters
The FIFA 11+ is one-size-fits-all.
But athletes are not.
Some need:
More strength
More coordination work
More exposure to plyometrics
More recovery
Blanket programs will always have limitations.
5. Integrate, Don’t Isolate
The best injury prevention programs are not separate from training.
They are embedded within a comprehensive S&C system that includes:
Strength training
Plyometrics
Sprinting
Change of direction
Recovery strategies
Injury prevention is not something you “add on.”
It’s something you build in.
Final Thought: The FIFA 11+ Isn’t Wrong—It’s Just Not Enough
The FIFA 11+ was a great step forward. It got us thinking!
But we’ve outgrown it.
If we continue to rely on a warm-up program to solve what is fundamentally a long-term athlete development (LTAD) issue, we will keep seeing the same outcomes:
Rising ACL injury rates
Underprepared athletes
Reactive instead of proactive solutions
At YAD, we say:
“You don’t prevent injuries with a program.
You prevent injuries by developing the athlete.”
And that’s the shift we need to make.
