Fig. 3From: The analysis of knee joint loading during drop landing from different heights and under different instruction sets in healthy malesNormalized joint power measured at the peak knee joint flexion moment for a ankle, b knee, and c hip. The error bars are SE. Significant interaction effects between height and instruction were observed in a–c. Levels not connected by the same symbol are significantly different. The negative power represents energy absorption and eccentric activation. The positive power represents energy generation and concentric activationBack to article page
