A muscle fiber contraction that does not result in a length change in muscle fiber. An system of exercise in which the muscle contracts but does not shorten when force is exerted on a stationary object, isometric exercise. Development of muscle tension with equal oppositional force. A muscular contraction in which the muscle increases tension…

A muscle fiber contraction in which the velocity of the contraction is kept constant. A muscular contraction performed against a controlled maximum resistance throughout the full range of motion. Muscle contraction during which the speed of the contraction is held constant and the resistance varied to match the force exerted.  

A muscle contraction in which the rate of limb displacement or joint rotation is held constant with the use of specialized equipment.
