Isokinetic is defined as an action in which the rate of movement is constantly maintained through a specific range of motion even though maximal force is exerted. It is a type of dynamic exercise often using concentric and/or eccentric muscle contractions in which the speed (or velocity) of movement is constant and muscular contraction (often maximal contraction) occurs throughout the movement.
Isolationism in psychology refers to a psychological state or behavior characterized by an individual's tendency to withdraw from social interactions and isolate themselves from others. It involves a preference for solitude and a reduced desire for social engagement. Isolationism can have various causes and consequences, impacting an individual's mental and emotional well-being.
Isomerization refers to a change in shape of the retinal part of the visual pigment molecule that occurs when the molecule absorbs a quantum of light. Isomerization triggers the enzyme cascade that results in transduction from light energy to electrical energy in the retinal receptors.
Isometric contraction is defined as a type of contraction with little or no shortening of the muscle resulting in no appreciable change in the joint angle.
