isotonic contraction This is a contraction in which movement does take place, because the tension generated by the contracting muscle exceeds the load on the muscle. This occurs when you use your muscles to successfully push or pull an object.
Isotonic contraction: A muscular contraction that results in movement of a body part or joint.

Isotonic Contraction
Isotonic contractions are those contractions in which the muscles contract and shorten, causing movement of the body part. Know more about isotonic contraction of muscles with this article.
Isotonic contractions (weightlifting) gained popularity when DeLorme and Watkins (1951) outlined a formula for success. Simply stated, the formula called for high resistance/low repetition exercise.
In isotonic contractions, the muscle contracts and shortens, giving movement. Nearly all the training you do is isotonic.

An isotonic contraction is different to isokinetic contractions because it is slowest at the start. This type of training needs special equipment to detect when a muscle is speeding up so it increases the load, slowing it down.
Isotonic literally means equal tension. An isotonic contraction is a contraction in which the tension remains constant as the muscle shortens or lengthens.
