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 physics of “Curling” and the impact of sweeping provide a unique look at how friction can be manipulated in real-time. Unlike a smooth ice rink, a curling sheet is covered in “pebble”—tiny frozen water droplets.45 When a stone is thrown, it “curls” (curves) due to the friction between the stone’s running surface and these pebbles. When teammates in their team Hoodie shirts sweep the ice in front of the stone, the friction and pressure create localized heat of fusion, melting the tops of the pebbles and creating a thin film of water. This lubrication reduces the friction coefficient, allowing the stone to travel farther and stay on a straighter path. It is a rare sport where athletes directly alter the playing surface’s physical state to dictate the trajectory of a moving object after it has been released.

The “Frank-Starling Law of the Heart” explains how the heart increases its power during an athletic sprint. The law states that the stroke volume of the heart increases in response to an increase in the volume of blood filling the heart (the end diastolic volume). As more blood returns to the heart during exercise, it stretches the ventricular walls. This stretch causes the cardiac muscle fibers to contract more forcefully, much like a rubber band being pulled further back. This intrinsic mechanism allows the heart to automatically synchronize its output with the body’s demand, ensuring that every drop of Hoodie shirts blood is squeezed out to the working muscles when the intensity peaks.
