From: Lower extremity joint kinetics and lumbar curvature during squat and stoop lifting
Joint powers during squat and stoop lifting. The ankle, hip, lumbar joints generated power(concentric contraction) but only the knee joint absorbed power(eccentric contraction) for the most part during squat lifting. The hip and lumbar joint generated power(concentric contraction) in contrast with the ankle and knee joint which absorbed power(eccentric contraction) for the most part.
