The turth about foam rolling and why it works:
Many people believe that foam rolling works by steamrolling your muscles, breaking up scar tissues and lengthening the muscle tissue. The problem: “Some research shows that it can take upwards of two hours to physically lengthen muscle tissue or break up scar tissue,” says Doug Kechijian, a doctor of physical therapy at Peak Performance in New York City. “And doing that is also a painful, painful process—foam rolling hits some sensitive spots but it generally doesn’t put you in pain.” If foam rolling isn’t physically altering the muscle, then what, exactly, is it doing? “There’s a pronounced difference between a muscle just feeling tight, and a muscle actually being tight,” says Kechijian. Feeling tight is related to muscle tone, while actually being tight is related to your muscle tissues physically becoming shorter.
