"... they simulated, in effect, a prolonged, exhausting and ultimately muscle-ripping leg day at the gym.... [T]hey gathered muscle samples from some animals immediately after their simulated exertions and then strapped tiny ice packs onto the legs of about half of the mice, while leaving the rest unchilled. The scientists continued to collect muscle samples from members of both groups of mice every few hours and then days after their pseudo-workout, for the next two weeks. Then they microscopically scrutinized all of the tissues, with a particular focus on what might be going on with inflammatory cells.... They... noted, in the tissue that had not been iced, a rapid muster of pro-inflammatory cells. Within hours, these cells began busily removing cellular debris, until, by the third day after the contractions, most of the damaged fibers had been cleared away. At that point, anti-inflammatory cells showed up, together with specialized muscle cells that rebuild tissue, and by the end of two weeks, these muscles appeared fully healed. Not so in the iced muscle, where recovery seemed markedly delayed....."
Lots of the comments over there object to the cruelty to the mice.
