The last time you saw a jogger donning a compression sleeve, you probably dismissed it as an effort to look cool. However, a compression sleeve is one of the most often recommended performance accessories an athlete could ever possess. One of the uses of the compression sleeve is to increase blood flow. How? First, let’s have a glance at the make-up material
Material and design of compression sleeves
Compression sleeves are manufactured from a range of fabrics. Nylon, Spandex, and Microfiber are the three most often used fabrics. Nylon is thin and durable. Spandex is sufficiently elastic, with the capability to expand to 500 percent its initial size.
The reason why compression sleeves are seldom made from 100 percent Spandex is that it’s not breathable. It is used alongside Nylon to offset this flaw while taking advantage of the distinct advantages of the two materials.
Microfiber stretches more than Nylon but less than Spandex, so it’s used to make more moderate compression socks. You can this product on amazon; you’ll notice that most of these products are made from elastic materials.
How compression sleeves increase blood flow
Compression sleeves work by manipulating the arm’s arteries and veins. Compression, or the force exerted by the compression sleeve on your arm, is measured in mmHg (millimeters of mercury). The most effective compression sleeve should exert at least 20 mmHg at the elbow or wrist.
The job of arteries is to supply your arm with fresh oxygenated blood. When under pressure (exerted by the compression sleeve), arteries tend to contract and dilate, thus ensuring consistent blood flow.
The dilation allows them to transport large volumes of into the muscles of the arms.
The job of veins is to remove deoxygenated blood from your arm. The compression exerted by the compression sleeve increases the effectiveness of their valves while decreasing the diameter of the tubes. This increases the speed at which the deoxygenated blood is removed from the muscles of the arm to the heart.
