It is called circumduction yet movement circular type that combines adduction, the abduction, the extension and the flexion. In this way, the sector of the body that moves manages to draw the figure of a cone.
Few joints can perform the conical motion characteristic of circumduction. The shoulder and the hips, for example, they allow circumduction since they make it possible to trace a wide circular path.
Circumduction can be said to be a movement set. Within a joint socket, the bone moves to describe a circumference at its distal end. Because the base is the joint, the circumduction creates a cone motion.
Take the case of shoulder circumduction. As we said above, circumduction implies adduction (the approach of the bone to the midline), abduction (the separation of the bone with respect to the midline), extension (one bone is stretched over another, increasing the existing angle between both) and flexion (one bone bends over another, minimizing the angle). All these movements in continuous form the circumduction that allows a person draw circles with your arms.
The hip circumductionMeanwhile, it encompasses movements that are carried out around three axes. At its greatest amplitude, the axis of the lower limb traces a cone with a vertex which is the center of the hip joint. Since the maximum amplitudes are not identical in all directions, the cone in question is irregular.
So far we have defined the technical aspects that arise from the mere observation of the body. In other words, our joints are capable of carrying out the movements that we have described and that, when acting together, lead to circumduction. However, beyond its use in anatomy, knowing these questions also served to design a wide variety of training physical to complement the gymnastics routine and keep the different parts of the body healthy.
One of the several exercises that can be performed to work the body taking advantage of circumduction focuses on the trunk. The first step is to tilt it to one side; in this case, let’s start to the right. As the next movement, we must place our hands on the sides of the waist to carry out the hyperextension, the extension of the torso backwards, so that our eyes point slightly upwards.
The third step is to lean the trunk to the opposite side, which in this example is the left. Always with the hands on the waist, we must carry out the opposite movement to hyperextension, which is simply called extension: consists of rotating the torso forward, as if we wanted to bend down to pick something up from the ground. The moment of the last movement has arrived, which consists of returning to the position initial, to repeat the whole process a few times.
You can also take advantage of neck circumduction to work your muscles. In this case we will have the following movements: we begin by flexing the neck, that is, bringing the head forward in a movement of rotation that brings the chin to the neck gently; then we tilt it to the side; We extend it, that is, we move our head back, as if we wanted to look up at the sky; finally we tilt it to the opposite side, to continue repeating the steps until we decide to reverse the direction of rotation.
Note that all these movements can lead to different types of joint damage if we do not do them by taking certain precautions, both in the limits and in the amount of repetitions. It is recommended to learn them from an expert before deciding to do them on our own.
