The nurse teaching a patient about ways to regain strength after a period of prolonged immobility advises the patient to seek assistance from a physical therapist

Question

Which type of exercise is performed using specialized apparatuses that use resistance at a constant, preset speed?
a. Isokinetic
b. Isometric
c. Isotonic
d. Isomorphic

Answer 1

A
Isokinetic exercise provides variable resistance to controlled movement. Physical therapists often use specialized apparatuses that combine the best features of isometrics and weight training. Isotonic involves movement of the joint during the muscle contraction (e.g., weight lifting). Isometric exercise involves muscle contraction without motion. The patient would apply pressure against an immoveable surface, such as pushing against a wall. "Isomorphic" is not a type of exercise; it describes a body type.
