Whole-body energy transfer strategies during football instep kicking: Implications for training practices

We hypothesized that fatigue induced by acute workload in short and intense games, might in either of two ways: by pushing lower limbs mechanics toward injury or by inducing opposed protective compensatory adjustments. We aimed at assessing the extent to which fatigue impact on joints kinematics and kinetics while performing repeated changes of direction (CoDs) in the light of the ACL risk factors.
