MEDICAL PHYSIOLOGY

Detailed explanation-1: -Isometric contractions are contractions in which there is no change in the length of the muscle. No joint or limb motion occurs. Isotonic contractions occur when the muscle changes length, producing limb motion. Concentric contractions occur when the muscle shortens.

Detailed explanation-2: -Isometric exercises are tightening (contractions) of a specific muscle or group of muscles. During isometric exercises, the muscle doesn’t noticeably change length. The affected joint also doesn’t move.

Detailed explanation-3: -During isometric muscle contraction the length of muscle does not change while muscle exert force . This type of movement can be seen while a person performs a maximal voluntary contractions (MVCs). Eccentric exercises increasing the concentric and isometric contraction as well.

Detailed explanation-4: -In summary, the two forms of isometric muscle action represents a position task (HIMA) that requires position control and a force task (PIMA) that requires the control of force.

Detailed explanation-5: -Isometric means “same length, ‘’ so that your muscles do not get longer or shorter by bending a joint. Isotonic means “same tension” so that the weight on your muscles stays the same.
