Figure 5From: Lower extremity joint kinetics and lumbar curvature during squat and stoop lifting Linear enveloped dynamic EMGs of lower limb muscles during squat and stoop lifting. Biceps femoris and rectus femoris showed large variances of activation during the squat lifting. Tibialis anterior, medial gastrocnemius, and biceps femoris showed large variances of activation during the stoop lifting.Back to article page
