Bloodstream
The blood is propelled by the heart, runs through our arteries to all of our organs it irrigates. From there, he returns to the heart through the veins: the return circulation. For arteries, the heart is the main driver of traffic. The veins of the lower back should our blood from the legs to the heart by fighting against gravity, which tends to force the blood to our feet.
Venous return
The natural mechanism more efficient of venous return is the activation of the muscle pump of the legs during walking. During walking, the crushing of the arch and calf muscle contraction compresses the veins and propel the blood toward the heart. Through a system of valves within these veins, blood can not back down in the legs. Each step propels blood 30cm3. Therefore, walking is an exercise very conducive to the smooth functioning of the venous circulation while immobility is bad.
Factors opposing the venous return:
- effect of gravity that keeps the blood to lower limbs,
- elasticity of veins overdistension limit the amount of blood driven into the heart,
- pressure caused by abdominal pressure during inspiration, or in case of
constipation.
AIRVEIN proposes a solution to "walk" in sitting position. The exercises performed with AIRVEIN used to activate the muscle pump and venous return while remaining seated.
