  • Celliant ® fiber is analogous to many light therapy devices that are approved by the FDA to treat aches and pains and improve blood flow. However, these devices must be powered by a battery or wall socket. In contrast, with Celliant ® fiber, this process is powered by the human body. The light energy that is emitted from the human body passes through material made with Celliant ® fiber, which absorbs and re-emits the light energy allowing the resulting energy to be reabsorbed by the body.

  • FIGS. 1 and 2 illustrate a long sleeve compression shirt 10 and a pair of compression pants 20 that are formed of one of the material combinations described above. Worn together, the shirt 10 and pants 20 form a full body suit, whereas worn separately, each forms a half body suit. The shirt 10 and the pants 20 can be worn before and/or after training to increase oxygen levels in the wearer.

  • the compression material is stretchable, the flaps can be pulled a large enough distance apart from one another to allow a subject to insert his or her legs into the resulting opening and pull the suit up over his or her torso.

  • compression accessories help the wearer in maintaining muscle stability, increasing circulation and enhancing recovery.
  • gradient compression is used in non-medical compression socks and calf guards or sleeves to exert more pressure as measured in mmHg at the ankle than at locations higher up the calf.

  • Clinical testing has been conducted to compare the oxygen levels in test subjects wearing regular street clothing to those same test subjects wearing a full body compression suit of the type described above. Clinical testing was also conducted to compare the oxygen levels in test subjects wearing conventional compression garments with oxygen levels in those same subjects wearing certain garments described above.
  • test subjects Eight of the test subjects were tested wearing full body compression suit 30 and then tested wearing street clothing. Seven of the test subjects were tested wearing full body compression suit 30 and then tested wearing convention compression suits. Each test subject in the first group of eight test subjects had his oxygen level measured for 90 minutes while sitting and wearing the full body compression suit 30 by two probes placed respectively at his sternum and at his calf. After 90 minutes, the test subject changed out of the full body compression suit 30 and put on his street clothing. The test subject's oxygen level was again measured for 90 minutes while sitting and wearing the street clothing by two probes placed respectively at the test subject's sternum and calf. The duration of the tests was chosen to be 90 minutes because studies have shown that the human body repeats its metabolic activities patterns
  • each test subject had his oxygen level measured for 90 minutes while sitting and wearing the full body compression suite 30. After 90 minutes in the full body compression suit 30 containing Celliant ® fiber, the test subject then changed into one of two conventional full body compression suits. The test subject's body oxygen level was measured for a final duration of 90 minutes while wearing one of the conventional full body compression suits. The two probes were placed respectively at the test subject's sternum and calf and the measurements were made with the test subject sitting down.
  • Tcp0 2 is the transcutaneous oxygen partial pressure in millimeters of mercury per square inch.
  • Transcutaneous oxygen is not the same as the arterial oxygen pressure measured using standard pulse oximeters.
  • Transcutaneous oxygen, Tcp0 2 is a local, non-invasive measurement of the amount of oxygen that has diffused from the capillaries, through the epidermis, to an electrode at the measuring site. It provides instant, continuous information about the body's ability to deliver oxygen to the tissue.
  • Tcp0 2 is dependent on oxygen uptake in the respiratory system, the oxygen transport/capacity of the blood and the general status of the circulatory system. Any impairment in a person's ability to deliver oxygen to the tissue can be detected immediately because the skin is ranked very low in the body's system of oxygenation priority, and the resulting drop in the Tcp0 2 level can be easily monitored.
  • the average oxygen level readings measured across all 8 test subject by probes placed at sternum and calf show an increase of more than 20% for test subjects wearing the full body compression suit containing Celliant ® fiber in comparison to street clothing.
  • the results show that wearing the full body recovery suit containing Celliant ® fiber for recovery is superior to wearing regular clothing because increased oxygen levels enhances or expedites recovery.
  • the average oxygen level readings measured across 7 test subjects by probes placed at the sternum and calf probes show an increase of more than 32% compared to the readings measured when test subjects were wearing one of the two conventional full body
  • compression clothing It is noted that when test subjects were wearing the conventional full body compression clothing, they had lower oxygen levels than when they were wearing regular clothing. This result highlights the importance of having compression clothing with suitable levels of compression such that the compression is not too high to cause tourniquet effects that actually impedes blood circulation.
  • FIGS. 8 and 9 illustrate the results of clinical testing where Hologenix, LLC measured oxygen levels in the tissue of the test subjects.
  • the test was originally developed to measure blood flow of diabetic patients.
  • the oxygen level data obtained from a test subject wearing full body compression clothing with Celliant ® fiber in comparison to wearing conventional athletic clothing over 90 minutes is illustrated in FIGS. 8 and 9.
  • the data in FIG. 8 is obtained from a probe located near his sternum, whereas the data in FIG. 9 is obtained from a probe located near his ankle.
  • the oxygen level is similarly measured with a blood profusion monitor and recorded as a Tcp0 2 reading. Data is taken for both the subject wearing full body compression clothing with Celliant ® fiber, as well as the subject wearing a standard athletic garment, which serves as a control.
  • the data indicates that the full body compression clothing with Celliant ® fiber amplifies oxygen blood levels by 15-20%.
  • the data in FIG. 8 shows that the oxygen blood level increased by approximately 19.7% after 30 minutes, approximately 18.3% after 60 minutes, and approximately 16.7% after 90 minutes.
  • FIG. 9 where measurements were taken near the ankle region, the data shows that the oxygen blood level increased approximately 35.1% after 30 minutes, approximately 55.6% after 60 minutes, and approximately 29.7% after 90 minutes.
  • garments described herein can be worn during either training or recovery, or they can be worn during both training and recovery. As discussed above, garments with a higher level of compression can advantageously be used during training to provide muscle support and to increase oxygen levels within the wearer of the garment.
  • the materials described above are not restricted to use in compression garments.
  • the garments are constructed to provide little if any compression pressure to the wearer. Such looser-fitting clothing can also increase oxygen levels in the wearer.
  • FIG. 10 shows a recovery shoe 800 with a tongue 810 having an inner surface 820 on which Celliant ® fibers are disposed. Substantially the entire inner surface 820 of the tongue 810 of the shoe 800 is lined with a fabric into which stand-alone Celliant ® fibers are threaded or woven in a netting configuration. In some embodiments, the fabric into which the Celliant ® fibers are threaded or woven is formed of conventional polyester. In certain embodiments, the composite fabric lining the inner surface 820 of the tongue 810 of the recovery shoe 800 contains 50% Celliant ® polyester fiber and 50% conventional polyester.
  • the Celliant fibers are capable of absorbing light emitted by a wearer and re-emitting the absorbed light, resulting in increased blood oxygen levels in the wearer. It is believed to be advantageous to include materials containing Celliant® fiber on the inner surface 820 of the tongue 810 of the recovery shoe 800 because the skin on the top of a wearer's foot is thinner than the skin on many other portions of the wearer's foot. Due to the thinner skin on the top portion of the foot, blood vessels and capillaries of the foot are in closer proximity to the Celliant® fiber on the inner surface 820 of the tongue 810 of the recovery shoe 800 than if the Celliant® fiber were to line other portions of the recovery shoe 800. As a result, it is believed that the absorbed energy that is emitted by the Celliant® fiber is better able to reach those blood vessels and capillaries of the user and can thus more effectively increase blood oxygen levels in the wearer.
  • the recovery shoe 800 includes elastic bands 825 that promote a close comfortable fit of the shoe.
  • the elastic bands 825 allow the recovery shoe 800 to be sized so that the foot of the wearer, when the shoe 800 is being worn, causes the elastic bands 825 to stretch and thus pulls the inner surface 820 of the tongue 810 snugly against the top portion of the wearer's foot.
  • the tongue 810 of the recovery shoe also has some elasticity due to the structure imparted by the construction (e.g., netting, weaving) of the composite fabric lining. This elasticity of the tongue 810 can further help to pull the Celliant® fiber on the inner surface of the tongue 810 into close contact with the skin on the top portion of the wearer's foot.
  • the light that is emitted by the foot can be directed more efficiently to pass through the Celliant® material on the tongue 810 of the shoe 800 before the light is absorbed and re-emitted back to the foot in a manner that increases the oxygen levels in the foot of the wearer.
  • the re-emitted light is more effectively re-captured by the foot because of the thinner skin in the top portion of the wearer's foot. In this manner, the blood oxygen level in the foot of the wearer can be increased.
  • the recovery shoe 800 is typically worn after exercising (e.g., after road races, such as marathons) to facilitate recovery of the muscles in the foot.
  • the recovery shoe 800 with the Celliant® fiber containing tongue 810 can be worn to improve blood circulation in the wearer's foot and reduce (e.g., eliminate) fatigue of specific muscle groups in the foot.
  • wearing the recovery shoe 800 can help to reduce (e.g., eliminate) aches and pains in the foot.
