Why do muscles become tight?
Muscles can become tight through repetitive movements, or a sedentary lifestyle, leading to local tissue dehydration and altered neuromuscular function. The central nervous system increases muscle tone due to a perceived need for protection. An increase in muscle tone causes the body to deposit more collagen around the myofascia, which can further increase muscle tightness. Understanding the origin of the tightness will determine the treatment method needed.
Stretching vs Foam Rolling
Depending on whether you have tightness through a heightened neuromuscular facilitation or through build of adhesions around the myofascia will determine whether stretching or foam rolling is necessary.
