ACL tears are the single most feared injury in soccer. For Sacramento club, high school, and college soccer players — especially female athletes — the risk is real, the recovery is brutal, and the career impact can last years. The good news: ACL injuries are largely preventable when athletes train correctly.
This isn't a medical article. It's a practical breakdown of what the research actually says and what Sacramento soccer players should be doing in the gym to protect their knees.
Why Soccer Players — Especially Female Ones — Are High-Risk
ACL injury rates are 2–8x higher in female athletes than male athletes playing the same sport. In soccer specifically, the non-contact ACL tear — happening on a cut, plant, or landing with no one touching the player — is the most common mechanism.
The underlying causes are well-documented:
- Quadriceps dominance — relying on quads over hamstrings/glutes during deceleration
- Knee valgus — knees collapsing inward on landing or cutting
- Asymmetry — one leg substantially stronger or more coordinated than the other
- Poor eccentric hamstring strength — the specific strength needed to slow the body down
The good news: every one of these is trainable.
The Four Pillars of Real ACL Prevention
Evidence-based ACL prevention programs share four non-negotiable components. Any program that's missing one of them isn't really doing the job.
1. Nordic Hamstring Exercise (Eccentric Hamstring Strength) Multiple large studies — including the FIFA 11+ research — show Nordic hamstring curls reduce ACL injury rates by up to 50%. Three sets, twice per week, progressed gradually.
2. Landing and Jump-Stop Mechanics Athletes need to be coached on how to land and stop: hips back, knees tracking over toes, soft landings. It's a skill, and it has to be drilled the same way a soccer move is drilled.
3. Single-Leg Strength and Stability Most soccer actions happen on one leg. Split squats, Bulgarian split squats, single-leg RDLs, and single-leg balance work are foundational.
4. Cutting and Change-of-Direction Mechanics Plant foot positioning, hip loading, and controlled deceleration taught at low speed before they ever happen at game speed.
A Baseline ACL-Prevention Week for Soccer Players
This is the minimum effective dose. A real program layers more, but if you're doing nothing, start here:
Session A (twice per week)
- Nordic hamstring curls — 3 sets of 5 reps
- Single-leg RDL — 3 sets of 8 per leg
- Box jump to stick landing — 3 sets of 5
- Lateral bound to stick landing — 3 sets of 4 per side
Session B (once per week)
- Split squat — 3 sets of 8 per leg
- Single-leg hop and stop — 3 sets of 4 per leg
- Reactive cut drill — 3–5 sets
Twenty minutes, three times per week. The research is clear: this cuts ACL injury rates dramatically in soccer populations.
The Sacramento Soccer Context
Sacramento soccer players — especially in clubs like Sacramento Republic Youth, Davis Legacy, Placer United, and San Juan SC — train year-round. That volume creates real injury exposure. Most club programs handle technical work and field fitness well but don't program dedicated prevention work.
Most high school programs don't either. The responsibility falls on the athlete and family to build it in — either independently, or with a performance gym that knows the sport.
Who Should Be Doing This?
- Any female soccer player U13 and up
- Any player with a history of ankle or knee issues
- Any player returning from a previous ACL injury (prevention literally doubles in importance post-injury)
- Any player training year-round with club + high school schedules
Male players benefit too — the risk is lower but not zero, and the strength and mechanics gains help on-field performance regardless.
How G6 Handles ACL Prevention
Our soccer program at G6 Performance Sacramento includes ACL-specific prevention work as a core pillar, not an add-on. Nordic hamstrings, landing mechanics, single-leg strength, and cutting drills are built into every training week for our soccer athletes.
We coordinate around club and high school schedules so prevention work complements your field sessions rather than piling on volume. Every new athlete starts with a free evaluation that includes a movement screen to identify specific ACL risk factors — and a plan to address them.

The Bottom Line
ACL injuries are not random bad luck. They're the predictable outcome of specific weaknesses and movement patterns — which means they're largely preventable with the right training. Twenty minutes, three times a week, is the minimum. Any Sacramento soccer player not doing that work is rolling dice they don't need to roll.
