Figure 3. — Mean knee joint flexion angles at initial contact (IC) and at the first peak vertical ground reaction force (vGRF) during the early landing phase for boys and girls across both limbs before (PRE) and after (POST) the fatigue protocol. Error bars indicate SDs. There was a statistically significant interaction of sex and fatigue for degree of change in knee flexion excursion (P < .001).
