The push-up is a popular physical exercise.
From the Latin flexĭo , flexion is the action and effect of bending the body or one of its members. It is an approximation movement between parts of the body through the action of the muscles .
Muscle flexion allows the forearm to be brought closer to the arm, for example. The movement opposite to flexion is known as extension . In this case, a distancing occurs between the bones or parts of the body.
Flexion as a physical exercise
The push-up , elbow flexion or push-up is a very common physical exercise to develop the pectoral muscles, triceps , deltoids, serratus anterior and coracobrachialis. The activity also helps improve anaerobic endurance.
To perform these push-ups, the subject must lie face down, with the palms of the hand pressed to the floor, at shoulder height. The person must lift their body with the strength of their arms and lower themselves back to the ground. The arms, therefore, flex and extend alternately. Those who want to increase the difficulty of the exercise perform push-ups with just one arm or adding some weight to the back.
However, they are not the only types of push-ups that occur within what would be the muscular meaning. Thus, there are also biceps and even leg curls. All these physical exercises are performed to achieve a magnificent state of shape and have an absolutely fibrous and muscular body.
The idea of flexion can be linked to bending the body or a specific limb.
The squats
In the specific case of what would be the legs, the type of push-ups that exist revolve around the well-known squats and with them both the quadriceps and the vastus medialis, the vastus lateralis and also the rectus femoris are worked. These types of push-ups are considered by experts to be some of the hardest, so it is recommended at all times that they only be performed by people who regularly practice physical exercise and have resistance in the muscles of the lower part of their body. .
There are many tips that exist and that must be taken into account by each and every one of the people who dare to perform push-ups in this sense. Among those is, for example, that it is essential to adapt the push-ups to what would be the age, state of health, weight and experience of the individuals in these matters.
Bending in mechanics, geology and linguistics
Mechanical bending , on the other hand, refers to the deformation experienced by an elongated structural element in a direction perpendicular to its longitudinal axis. Beams, plates, and sheets are examples of these elements that typically withstand different levels of mechanical bending.
However, we must not forget that the term in question is also used within the scientific sector of geology. In this case, within this discipline, the word bending is used to define the soft shear bending that the different strata of the earth experience.
For linguistics , finally, inflection is the modification that words undergo through the constituent morphemes to express various functions within a sentence . These alterations are linked to agreement and dependence on different sentence elements.
