Isokinetic training is best defined as generation of a muscular force with visible joint movement that occurs at a constant speed but with variable external resistance.

Isokinetic training is best defined as generation of a muscular force with visible joint movement that occurs at a constant speed but with variable external resistance.

• A. Generation of a muscular force with visible joint movement that occurs at a constant speed but with variable external resistance
• B. Contraction with no joint movement
• C. Force produced only during eccentric contraction
• D. Only maximal voluntary contraction with no movement

Answer: (A)

Isokinetic training centers on moving a limb at a constant speed through a joint’s range of motion, while the external resistance automatically varies to keep that speed fixed. The device adjusts the load in real time so you can generate force, but the movement speed remains the same, resulting in visible joint motion at a steady angular velocity. This combination of movement with accommodating resistance is what sets it apart from other types of contractions. It isn’t limited to only eccentric work, and it isn’t about holding a contraction with no movement (that would be isometric). During an isokinetic workout, you can produce force during concentric or eccentric phases, but the key defining feature is maintaining a constant speed with variable resistance.
