This, 'cold spray therapy' has it's roots in European soccer and began with the, 'cold sponge therapy.' A sponge soaked in freezing cold water then applied to players knee or ankle, etc after a, "knock." The results saw almost all players injured, were back up and running full speed within a few moments after what appeared to be a devastating injury. The professional leagues around the world adopted this therapy and then they also moved to the, 'cold spray therapy' which the Russian wrestlers soon adopted. The ingredients are unknown, but have been linked to the embryonic cells of the Chinstrap Penguin.
