The use of “Cryotherapy” (extreme cold exposure) is designed to manipulate the body’s vasoconstriction and vasodilation cycle to manage systemic inflammation.46 In a cryotherapy chamber, temperatures drop below -110°C, causing blood to rush away from the extremities to protect the core. Once the athlete exits and puts on warm Hoodie shirts, “reperfusion” occurs—a massive surge of oxygenated, nutrient-rich blood returns to the muscles. This process is believed to flush out metabolic waste and reduce the levels of C-reactive protein (CRP) and other inflammatory cytokines. While controversial in its ability to build long-term muscle, it is highly effective as a “neural reset,” dampening the central nervous system’s perception of pain and allowing athletes to tolerate high-frequency training blocks during a competitive season

The Viscoelastic Properties of Tendons act as a critical “mechanical buffer” during high-impact sports. Unlike a simple rubber band, tendons exhibit time-dependent behavior: the faster they are loaded, the stiffer they become. This is essential for power sports; during a sprint or jump, the tendon stiffens to efficiently transmit the massive forces generated by the muscles to the bones. However, if the load is applied too slowly or too repetitively without rest, the tendon can undergo “creep,” where it deforms permanently, leading to tendinopathy. Athletes use Hoodie shirts training to increase the collagen cross-linking in their tendons, essentially “tuning” their biological springs to handle higher velocities without failing.

The application of Hyperbaric Oxygen Therapy (HBOT) in professional sports has moved from specialized medical clinics to the training facilities of elite teams as a means to compress recovery windows.36 By breathing 100% oxygen in a pressurized chamber, the amount of oxygen dissolved in the athlete’s blood plasma increases significantly (up to 10–15 times the normal concentration). This “super-saturation” allows oxygen to reach tissues with poor blood supply more effectively, accelerating the production of collagen and the activity of white blood cells. For athletes recovering in Hoodie shirts from crush injuries, ligament tears, or severe bruising, HBOT can reduce edema (swelling) and stimulate angiogenesis, potentially cutting rehabilitation time by as much as 30%.37
