Why do foam rollers work?
In: Biology
Your body breaks down glucose for energy. When you’re working out, so you have less oxygen, your body breaks it down into something called lactate. High lactate increases the acid levels in your muscles, which slows glucose production. This is a defence mechanism that protects the muscle.
Foam rollers help spread out the lactic acidosis, which helps with the burning sensation you get. They also increase blood flow and reduce tissue tension, also helping you recover faster.
