Strength and Flexibility Asymmetries as Risk Factors for Injury
- Athletes experienced more lower extremity injuries if they had knee flexor and hip extensor strength asymmetries (Knapick 1991, Nadler 2001)
- Eccentric hamstring strength asymmetries were at greater risk of sustaining a hamstring muscle strain. (Fousekis 2011)
- Hamstring/quad ratio asymmetry (Soderman 2001)
- Ankle strength asymmetry (Baumhauer 1995)
- Asymmetrical landing patterns predict second ACL tear in previously reconstructed athletes (Paterno 2010)
