Phlebological aspects

Elastic compression may be the winning weapon in maximizing sports performance and improving well-being providing that it is designed in such a way as to guarantee perfect wearability, an essential condition for obtaining the physical compression required.
(taken from "La terapia compressiva nell'insufficienza venosa cronica" (Compression therapy in chronic venous insufficiency) G. Arpaia, Cizeta Medicali S.p.A.)

The cardiovascular system is made up of some hollow organs.

The heart, a muscle that acts as a pump by contracting (systole) and relaxing (diastole), and the blood vessels divided into arteries (which take blood from the heart to the tissues), veins (which take it from the tissues to the heart) and capillaries (which permit blood-tissue exchanges). From the left part of the heart, the blood is forced at a high pressure into the large arteries, the Aorta and its main branches.

Arteries are like tubes carrying blood at a high pressure, rich in oxygen and nutrients. Arteries branch out further to become arterioles and capillaries. At this point, the transport function ceases and the exchange with and nourishment of the cells of the organs begin.

Having passed through the capillaries, the refluent blood carrying little oxygen and above all cellular waste and metabolites flows into venules, which take it back to the right part of the heart through increasingly large vessels. It should be pointed out that one of the main differences between arteries and veins is the difference in pressure of the blood, which is higher in the arteries.

The blood flow conditions in the lower limbs is more complex due to the increase in hydrostatic pressure (in the upright position).

Venous return is therefore ensured essentially by:

   

the venous foot pump and the calf muscles

  

when the muscles contract, they force the blood to flow upwards by compressing the deep veins

  

the action of the venous valves prevents backflow

From the anatomical point of view, the venous system of the lower limbs is made up of a superficial system and a deep system that communicate with one another. While walking, the spongy vascular tissue made up of capillaries situated at the base of the foot, compressed between the weight bearing base on one side and the bone base on the other, acts by pushing the blood towards the veins in the leg. As the leg muscles contract, they compress the deep veins, thus forcing the blood upwards (also through the action of valves that prevent backflow).

The venous system of the lower limbs is therefore characterized by a precarious and complex balance between hydrostatic pressure, concentration of the chemical substances present in the plasma and the tissues, the efficiency of the venous valve system, adequate plantar support and muscle tone.

Cizeta Medicali, a leader in the study of elastic compression on venous haemodynamics set up their Sports Division specifically to design Compression Zone®, a line of high-technology products which, on the basis of sophisticated wearability tables, provide perfect elastic compression on the legs of each individual athlete.
In addition, through its technologically advanced components such as antiseptic and heat dissipating yarns, Compression Zone® ensures greater hygiene and complete evaporation of sweat.
Compression Zone® improves cardiocirculatory function (the increase in venous return increases cardiac volume so that the heart rate is lower at the same cardiac output and the output is higher at the maximum heart rate) and also acts on the metabolism by optimizing the transport of nutrients to the muscle and increasing its efficiency (transport of nutrients to the muscle cells).
Both these conditions are crucial factors in optimizing performance.

Compression Zone®:

increases cardiocirculatory efficiency

reduces the increase in heart rate

increases maximal work (muscular power)

optimizes muscle metabolism
