In order to predict how much tension a muscle can produce when contracting, it is important to consider the ______ relationship
serg [7]

The muscles are composed inside mainly of fibers, filaments and proteins, where it is important to consider the <u>length-tension</u> relationship of the thick and thin filaments to know the tension.

<h3>What is muscle contraction?</h3>

It is an organized and natural event that takes place at the level of the muscles when the fibers and proteins inside them come together, and tension is produced in the area.

<h3>Characteristics of muscle contraction</h3>

  • In a muscle contraction, a tension is generated that depends on the length-tension relationship, which causes a displacement of the muscle filaments.

  • The proteins actin and myosin join together, and a force is generated so that the final movement is achieved.

  • To know the tension, the muscle changes length and measurable external work is produced from the force and distance traveled.

Therefore, we can conclude that the contraction allows us to make movements to reach and carry our extremities to different places.
