Machines that control the speed of contraction so the limb moves at constant velocity and the muscle is loaded maximally through the full range of motion.
Detail
Accommodating resistance devices attempt to control the speed of contraction through various mechanisms, including electronic servo-motor control systems and hydraulic chambers. They are described as accommodating resistance machines because they attempt to exactly match the variation in torque produced throughout a movement with an appropriate resistance. Thus, the limb moves with a constant angular velocity, and the muscle group is trained maximally through the range of motion.
Examples of these machines include the Cybex (Isokinetic Dynamometer), Kincom, Biodex, and Orthotron systems.
Key facts
- Controls speed of contraction via servo-motor or hydraulic mechanisms.
- Matches resistance to the torque produced throughout the movement.
- Limb moves at constant angular velocity; muscle trained maximally through ROM.
- Examples: Cybex (Isokinetic Dynamometer), Kincom, Biodex, Orthotron.
Connections
- Variable Resistance Training (Machines, Cams) — both aim for maximal loading through ROM; this controls velocity rather than load shape.
- Dynamic Constant External Resistance (DCER) Training — contrasts with constant external resistance.
- Principle of Specificity (SAID) — testing specificity affects measured gains.
