Isokinetic training is defined as which statement?

• A. Muscle contracts at a constant speed throughout the entire ROM.
• B. Muscle contracts at a variable speed throughout the ROM.
• C. Requires specialized rate-limiting equipment.
• D. Allows only eccentric contractions.

Answer: (A)

Isokinetic training centers on moving at a constant speed through the full range of motion, with the resistance adjusting to keep that speed steady. This constant angular velocity is achieved with specialized equipment, like an isokinetic dynamometer, that responds to how hard you push or pull. Because the speed is fixed, you can exert maximal effort throughout the entire ROM. The other statements don’t fit: a variable speed throughout the ROM describes other forms of resistance training, not isokinetic; while equipment is needed, the defining idea is maintaining constant speed, not a rate-limiting mechanism; and isokinetic contractions can be concentric or eccentric, not limited to eccentric only.
