Elasticity is the ability to stretch without breaking and then recover its original shape.
Before entering fully into establishing the meaning of the term elasticity , let's know its etymological origin. In this case, we can state that it is a word that derives from Latin, specifically from “elasticus”, which, in turn, emanates from the Greek “elatostikos”.
Elasticity is the property of that which is elastic : that is, it can stretch without breaking and then recover its shape . The idea also refers to what accepts different explanations or interpretations and what has the ability to adapt to different circumstances.
The concept in physics
In the field of physics , elasticity is the quality presented by materials that, when subjected to the influence of an external force, deform, but recover their original shape once said forces are eliminated. The deformation of the elastic elements, therefore, is not permanent, but reversible .
A rubber band , for example, can be stretched with your hands. If the person stops using that force, the rubber returns to its original state. It can be said, in short, that this object has elasticity.
Muscle elasticity is linked to muscle elongation.
muscle elasticity
In the field of physical exercise we talk about muscle elasticity . Specifically, the need to carry out activities that improve that in order to elongate the muscles and also ensure that they have a greater range of movements is established.
Starting from that we can establish that this objective can be carried out with different methods such as passive dynamic, passive static, active dynamic and active static. These can be done as stretches before any physical activity and also after having carried out the same.
Thanks to all these exercises for muscle elasticity, other important benefits will be achieved, such as the following:
-Considerably reduce the risks of suffering an injury.
-It also helps to improve body posture.
-It goes without saying that they are also very useful in reducing muscle discomfort that may be felt.
-In this list of advantages of exercises for the aforementioned elasticity we cannot fail to include the one that improves both muscle coordination and blood circulation.
-They contribute to generating a feeling of physical well-being.
-Constantly improve physical performance.
The notion in medicine and economics
In the field of medicine , elasticity is linked to the changes that occur in one variable due to the modification of another variable . This is the percentage change of a variable X with respect to a variable Y.
To measure elasticity, both variables must be linked through a certain dependency relationship , which causes changes in one of them to impact the other. Take the case of the number of cell phones (mobile phones) sold and the price of these devices: as the price increases, sales decrease, since sales depend on price. This type of analysis is known as elasticity of demand .
