Back on Track's joint and muscle support are all made of functional textiles with heat reflective properties. The textile is a synergy of ancient Chinese experience and modern scientific textile technology. During the manufacturing of polyester- or polyester fibres, the ceramic particles are fused into the fibres. When heated, the ceramic particles radiate a heat back towards the body. This reflected heat is long-wave heat radiation, which is also known as long wave infrared radiation.
It is well established and documented that long wave infrared heat radiation increases the blood circulation. The increased blood circulation in the tissues helps to relieve muscles tension and improves performance. One important property is the injury prevention effect, which you get when the protections are used for training and competition.
Deepening in the function
Heat energy can be transported in three ways: conduction (transfer), convection or radiation.
People and animals radiate body heat, both at rest and in activity, however less heat is radiated when at rest. When a material is hit with heat rays, three things can occur.
A material has not only an absorption spectrum but also an emission spectrum. An emission spectrum essentially means that different materials radiate heat of various wavelengths within different temperatures. The amount of radiation and the radiation wavelength varies depending on the heat source temperature and the emission spectrum of the heat source materials. Generally, one can say that the lower the temperature heat source is the longer the wavelength of the heat radiation.
When manufacturing the polyester and polypropylene fibers that Back on Track products are made of, ceramic particles are fused into the textile fibers. The selection of these ceramic particles is based on which absorption and emission spectrum they contain. The result is that when the ceramic particles absorb the body's heat radiation, they expel heat of a specific wavelength, which is based in the long-wave infrared zone of the thermal radiation spectrum. It is well established and documented that long wave infrared heat radiation has a pain reducing effect and increases blood circulation.
Just like other materials, body's tissues has its own absorption spectrum. The wavelength that the ceramic particles issue is absorbed in the cells. A signal is sent to the brain telling it that heat energy has increased, to which the brain opens up the veins. The absorption happens not only in the skin but also deeper down the tissue, which makes the veins wider not only superficially but also in the muscles and around the joints. The increased blood circulation in the tissues relieves muscle tension and strengthens the body's own ability to reduce inflammations and heal injuries. The products are therefore often used in cases where inflammation is part of the problem. Another important application is injury prevention, which you get when the protections are used for training and competition.
