Isokinetic Exercise is defined by which characteristic?

Isokinetic Exercise is defined by which characteristic?

• A. Resistance is given at a fixed velocity of movement with accommodating resistance
• B. The muscle length does not change during the movement
• C. The resistance remains constant regardless of effort
• D. The exercise uses no external resistance

Answer: (A)

Isokinetic exercise is defined by moving at a preselected constant speed, with the resistance adapting to keep that speed steady. The equipment provides accommodating resistance: when you exert more effort, the machine increases resistance just enough to maintain the fixed velocity; if you ease off, the resistance drops while the speed remains constant. The limb clearly moves through the range of motion, so the muscle length changes during the contraction. The resistance is not fixed—it's dynamic and tailored to your effort to preserve the set velocity. And yes, there is external resistance provided by the device, not zero.
