a
SJ, stop-jump; VJ, vertical jump; DJ, drop jump.
b
Negative percentage change indicates decreased anterior tibial shear force or knee flexion moment.
c
NA, not available (ie, means and measures of variability were not provided in the study).
d
Indicates significant change following completion of injury prevention program.
