Table 7 Categorization of 10 technique flaws from the Tuck Jump Assessment into modifiable risk factors
Modifiable risk factorDescriptionTechnique flaws
Ligament dominance“Imbalance between the neuromuscular and ligamentous control of the dynamic knee stability”Lower extremity valgus at landing
Foot placement not shoulder width apart
Quadriceps dominance“Imbalance between knee extensor and flexor strength, recruitment, and coordination”Excessive landing contact noise
Leg dominance or residual injury deficits“Imbalance between the 2 lower extremities in strength, coordination, and control“Thighs not equal side-to-side (during flight)
Foot placement not parallel (front to back)
Foot contact timing not equal
Trunk dominance/core dysfunction“Imbalance between the inertial demands of the trunk and core control and coordination to resist it”Thighs do not reach parallel (peak of jump)
Pause between jumps
Does not land in same footprint (excessive in-flight motion)
Technique perfectionNot definedTechnique declines prior to 10 s
