To fully understand this Grip Strength exercise there most be an understanding of the foundational physiological mechanisms, which are involved. These mechanisms are all incorporated into the muscular system of the body and its foundational unit known as muscle. A muscle can be defined as a bundle of fibrous tissue connected to two or more bones by tendons giving it the ability to contract and therefore inducing movement to a specific part of the body. The muscles within the human body are differentiated into three classes known as skeletal, smooth, and finally cardiac. Smooth muscle is an involuntary muscle (under control of the autonomic nervous system) that is mainly found within the walls and organs that participate in digestion such as the stomach, intestines and esophagus, but can also be found within blood vessels as well (Argosy Publishing, 2016). Furthermore smooth muscles lack striations, due to the absence of the …show more content…
These muscle fibers are composed of myofibrils, which not only give the muscle its striated appearance but also are also composed of contractile proteins known as actin (thin filaments) and myosin (thick filaments). Each actin protein has a binding site for myosin, which is regulated by two proteins known as Tropomyosin and Troponin. Both of these regulator proteins inhibit the binding of myosin to actin by overlapping the binding sites in a confirmation that could be described as a ribbon (Tropomyosin) and a thumbtack (Troponin). Each skeletal muscle is then divided and encapsulated by three difference layers of connective tissue. The first of these layers enclosed the whole skeletal muscle and is known as the epimysium, the second layer of connective tissue called the perimysium encloses each fascicle and finally the last layer of connective tissue which encapsulates each muscle fiber, which is known as the
