In isokinetic exercise, which parameter remains constant during movement?

• A. Speed
• B. Force
• C. Torque
• D. Power

Answer: (A)

The main idea here is that isokinetic exercise keeps the movement speed constant throughout the range of motion. The machine or device sets and maintains a steady angular velocity, so no matter how hard you push or pull, the limb moves at the same speed. The resistance the device provides adjusts to your effort in order to hold that speed steady. Because of this, the force you generate and the torque can vary with joint angle and effort, and power will change as torque changes even though speed stays fixed. This is why speed is the parameter that remains constant in isokinetic movement.
