Concept in Definition ABC

The prefix "iso" means "equal" and the term "metria" comes from the Greek "metron", which means "measure". Thus, isometry refers to a singularity of the geometry. However, isometric issues are also present in nature and in physical preparation.

In geometry

There is an isometric transformation when there is no alteration of the shape or a change in the size of a geometric figure. Thus, there is only one change of position in the figure.

Translation is a movement that occurs when a figure is slid in a straight line towards one direction. Three aspects are involved in any translation:

1) the direction (right, left, up, down ...),

2) the magnitude (the specific distance traveled) and

3) direction (movement horizontally, vertically or obliquely).

From a formative point of view, isometry is present in relevant mathematical questions: obtaining figures, decomposition into parts or skill space. In the field of early childhood education, the little ones have to become familiar with things and shapes that have some kind of isometry, but also with those that are asymmetric.

In nature and in the world around us

If we cut an apple in half we will see that the two parts are symmetrically identical. The images that are projected on the water are coincident and, therefore, there is an isometry between the two. The rose windows of Gothic cathedrals, the mandalas, the tessellations, the structure of a flower or the blades of a mill also have this geometric singularity. In short, all those designs with translations and movements have this characteristic.

An isometric exercise is one in which a force to an object that presents a certain resistance and therefore no body movement occurs

These types of exercises are performed to gain strength and muscle mass and are characterized by being static and not dynamic. Pushing your arms against a wall for a few seconds or staying in a position using a force would be two examples of isometric exercises.

This type of training is also useful for rehabilitation, as it helps to strengthen damaged or atrophied tendons and muscle tissues.

Isometric strength training has some additional benefits: It can be done anywhere, it reduces the risk of injury, and it is suitable for any type of athlete. However, you should not abuse this type of exercise because it reduces the elasticity muscular and does not promote coordination intermuscular.
