Which type of resistance does an isokinetic exercise device provide?

• A. constant resistance
• B. variable resistance
• C. accommodating resistance
• D. no resistance

Answer: (C)

Isokinetic devices are designed to keep the limb moving at a constant speed regardless of how hard you push or pull. To do that, they continuously adjust the resistance in response to your effort. If you exert more force, the machine increases resistance to maintain the set speed; if you ease off, resistance decreases accordingly. This adaptive loading is what we call accommodating resistance—the load changes to match your effort to keep the movement velocity constant. That’s different from a constant load (a fixed resistance throughout the motion) or a purely variable load that changes with ROM independent of your instantaneous effort. So the isokinetic device provides accommodating resistance.
