Isometric muscle contractions happen when the muscle stays the same length, concentric contractions occur when the muscle shortens, and eccentric contractions occur when the muscle lengthens.
Isotonic contractions involve muscle actions where the muscle length changes as it contracts against a constant load. There are two types: concentric contractions (shortening of the muscle during contraction) and eccentric contractions (lengthening of the muscle during contraction).
Different types of muscle contractions
Tonic muscle contractions are sustained and steady, while phasic muscle contractions are brief and intense. Tonic contractions last longer and have a lower intensity, while phasic contractions are shorter in duration but have a higher intensity.
Isotonic contractions. This happens when the muscle shortens as it contracts

The heart muscle is the muscle that normally exhibits arrhythmic contractions. These contractions are controlled by the heart's internal pacemaker system, which generates electrical signals to regulate the heart rate and rhythm.
Tetany is the term for the muscle contractions that may be caused by hypoparathyroidism.
Phasic muscle contractions are quick and powerful, used for activities like jumping or throwing. Tonic muscle contractions are sustained and steady, used for activities like maintaining posture or holding a position.
