The purpose of the present study was to examine the relationships among the passive properties of the muscle–tendon unit and muscle cross‐sectional area (CSA). Our findings indicated significant relationships between muscle CSA and passive stiffness ( P < 0.05; r = 0.830) and muscle CSA and passive energy absorption ( P < 0.05; r = 0.765). Since passive stiffness and the ability to absorb passive energy decreases with many diseases, these findings may support the need to maintain or increase muscle CSA. Muscle Nerve 39: 227–229, 2009
