Torque-angle curve. Maximal voluntary isometric torque of trunk flexor muscles at multiple sagittal plane trunk positions for males and females. The asterisk denotes a significant sex difference in torque at this position (p < .05); the number sign denotes a significant difference in maximal torque (males and females collapsed) from that at the most extended position (−40°) (p < 0.05)
