Final answer:
Myofascial rolling can lead to muscle relaxation and improved flexibility through the processes of vasodilation and increased blood flow. Hence , the correct answer is option B.
Step-by-step explanation:
The two physiological responses that can occur from myofascial rolling are muscle relaxation and improved flexibility. This form of self-massage exerts pressure on the muscles and the surrounding connective tissue, or fascia, helping to release tightness and tension. The action of rolling can help to induce vasodilation, which is the widening of blood vessels, improving blood flow to the muscles. Additionally, by working on the fascia, myofascial rolling can lead to an increased range of motion, contributing to better flexibility.
Vasodilation is particularly relevant as rolling stimulates the muscle and fascia, which can help in the recruitment of more blood to the area, bringing oxygen and nutrients while also removing waste products, which can aid in the recovery process. Moreover, as blood vessels in skeletal muscle can respond to sympathetic input by dilating, this increased blood flow during myofascial rolling helps meet the metabolic demands of the muscles.
