Abstract

The dynamic contractile behavior of the muscle is commonly represented by the torque-velocity relation, which is an inverse hyperbolic relationship between muscular tension and the velocity of muscle action (shortening in concentric, static in isometric and lengthening in eccentric muscle actions). This relationship has been well established for extremity muscles but this study extended the range of trunk velocity (-60 to 60°/sec) that had been used for trunk extensors in the past. The effect of velocity was significant on trunk extensor strength, while the expected plateau was not found within the speed considered.
