Compression fabrics have become so widespread in endurance sports that the skeptics among us often think of it as a modern day equivalent to snake oil. But, Zensah is here to tell that compression is very real. In fact, its Reflect Compression Leg Sleeves effectively employ gradient compression in order to improve the flow of oxygenated blood to your lower legs. This helps to reduce both fatigue and recovery time. And since most of us spend our time training in the real world, these leg sleeves are built out of reflective materials. So, you're able to add a touch of safety out there on the road. Zensah's compression leg sleeves operate on the principle of gradient compression. In essence, gradient compression means that these leg sleeves are tighter at the bottom, and gradually become less constrictive as they approach the top. But, the reason for this may not be immediately apparent. Basically, by applying the greatest pressure at the areas farthest from the heart, a compression piece increases arterial pressure. If that doesn't sound like a good thing, don't worry, because not only is increased arterial pressure at the extremities desirable, it's also essential to experiencing the full benefit of compression clothing. It works much like a garden hose. If you kink the hose, it allows pressure to build, and when the kink is released, that water flows much faster. Arterial pressure works on the same principle. By increasing pressure on the arteries at your extremities, these compression leg sleeves force your body to pump blood back to your heart at a faster rate, which allows for a greater quantity of freshly oxygenated blood to enter your legs. And receiving oxygenated blood is at the core of the benefits recognized through compression clothing. More oxygen to your muscles equates to a reduction of fatigue and improved recovery time. So, you're able to get more from your workout. And, in addition to the aforementioned, Zensah recommends these sleeves for anyo...
