Ice Hockey injury prevention for girls.

Remove when in doubt

Any suspected concussion means removal from play and clinician evaluation before a graded return.²

Graded return protects the brain

After a concussion, return follows staged steps from symptom-limited activity to full contact, moving on only when symptoms stay settled. Contact comes last and needs clinician clearance.^2,1

Energy availability comes before every other adaptation

When an athlete does not eat enough to cover the energy her training burns, the body downregulates the systems it treats as optional first — menstrual function, bone remodeling, immune response, and tissue repair. The IOC calls this Relative Energy Deficiency in Sport (REDs), and it raises bone stress injury and soft-tissue injury risk independent of how good her mechanics are. Amenorrhea (no period for three or more months) in an athlete is a clinical finding, not a convenience.

Puberty changes the machine mid-season

The adolescent growth spurt lengthens the levers (femur, tibia) faster than the neuromuscular system recalibrates, and in girls the strength gain that accompanies growth is smaller than in boys. The result is a two- to three-year window of reduced dynamic knee control, wider dynamic valgus on landing, and higher relative injury risk. Programming should get more — not less — landing and single-leg work through this window.

Menstrual-cycle phase is a variable, not a taboo

Hormonal fluctuation across the cycle affects laxity, neuromuscular control, thermoregulation, and perceived exertion, and prospective data in international footballers found injury incidence differed by cycle phase. The practical action is not to restrict training but to track: a simple cycle log next to load data lets athletes and staff see patterns and adjust intensity, hydration, and fueling.
