The word isotonic is framed from a Greek word named is, which means some and toniko, which means tensions. Isotonic contractions are contractions that occur with some tensions. Although there is no change in the length of muscles, there does occur a change in the muscle fibres to shorten, which helps to increase the strength of muscles.

Pushing an object in a stationary position, a person holding a weight in a special place are two examples where an isometric contraction takes place in a muscle. This means that the amount of force produced is directly proportional to the amount of increase in the length of the muscle pull. During an isotonic contact, the muscles remain their normal length.

This is exactly how an isometric contraction takes place inside the muscles. Till this person faces no resistance, he or she will have no change in his or her body length. When a person holds his or her or her length against his or her or her body. This, in short, means there will not take place any excess for the opposite force. The tension in a muscle increase exceeds the load that is initially carried on without having any change in the length of muscles. In this word, iso means some, and metric means length. Isometric contractions are contractions that are said to be of the same length waves. Energy High efficiency of energy is required. External work There is a non-occurrence of external work. The latent period and contraction period inversely proportional to the relaxation period. Period changes The latent period and relaxation period is inversely proportional to the contraction period. There is no change in tensions that is, they are always constant. Tensions There are some changes that occur in tension. Comparison Table Between Isometric and Isotonic Contractions Parameters of Comparison Isometric Contractions Isotonic Contractions Length There is no change in length. There is a certain amount of tension or contractions that are exerted in an isotonic contraction.

In isotonic contractions of muscles, there is a change in lengths of muscles, but the tensions are the same or contracted. This, in shorts, means there will not take place any chance of exceeding the opposite force.
