Soccer.
Pro · Youth · Lifestyle. The whole cell.

Four patterns soccer training science centers on — repeated-sprint ability across 90 minutes, cutting/decelerating/COD biomechanics distinct from football, the groin/adductor/FAI cluster from kicking + cutting + sprinting hip kinematics, and FIFA 11+ as the most-validated injury-prevention warmup in any sport. Injury science is mature in this cell; performance science is partial; position-specific work is the next layer.

Bucket 01 Pro · soccer 6 specific · 30 generic-tagged · injury-mature

Pro soccer's injury-science backbone is well-covered. The 6 sport-specific entries map the canonical clinical cluster — ACL non-op, FAI, adductor, groin, hamstring, Nordic education. Performance work (RSA, sprint mechanics, GK reactivity) is inherited from generics. Position-specific entries are 0.

Bucket 02 Youth · soccer 1 specific · 12 LTAD-generic · FIFA 11+ anchored

Youth soccer benefits from the most-validated injury-prevention warmup in any sport (FIFA 11+ for kids). LTAD strength + growth-plate routines apply broadly. Travel-team volume management and girls-specific ACL prevention (4-6× higher female ACL incidence in soccer) are gaps.

Bucket 03 Lifestyle · soccer 1 specific · 30+ generic-tagged · 1 new this session

Lifestyle soccer is the adult-rec / masters / weekend-warrior population. Rec-league ACL incidence in masters exceeds NCAA Division I in some surveillance — a real safety story. Generic Zone 2 + tendon + mobility cover; masters-aware FIFA 11+ is being drafted this session.

The evidence backbone

Soccer entries trace back to the following primary literature. The injury-science literature in soccer is unusually deep and well-validated.
