In early 2018, Scientific Reports published an article reporting that the interstitium is not just a layer of connective tissue, but is also composed of previously unseen fluid-filled spaces that lie just below the skin's surface, as well as around the lungs, digestive system and other organs. Kyle Stull, a NASM trainer, says, "As someone moves, these layers facilitate the sliding and gliding of tissues across each other, allowing for smooth movement."
Foam rolling will create pressure that can help "push" the fluid to move back and forth within these spaces. Stull notes, "Such movement will help to circulate out waste products produced by the cells, which then allows fresh fluid to enter the space. The transfer of fluid helps to revitalize areas of stagnation.... Movement will be reintroduced to this layer, leading to the demonstration of flexibility and improved movement patterns."
My take-away is that there are even more reasons to foam roll regularly! This self-massage therapy not only smooths out fascia and muscle adhesions but also moves interstitial fluid around the cells for healthy function.

It doesn't take much time or effort to give your body the "love" it deserves. Make foam rolling a priority and reap the benefits of happy, flexible muscles.
