Effects Training Has on Muscle Cell Hypertrophy

As discussed in paper one, readers can see the complexity that lies behind muscle fibers and the contractile units that make up each muscle cell. At the normal physiology level, muscle fibers exist as complex bundles of small muscle filaments. These filaments, known as actin and myosin bind in such a way that allows for sarcomere contraction. In assistance with calcium flowing into muscle cells, proteins known as tropomyosin and troponin ultimately allow “cross bridging” to occur. Throughout the body three types of muscle fibers exist, these types of fibers are slow oxidative, fast oxidative and fast glycolytic. Activation or recruitment of these fibers varies from person to person depending on the muscle specificity needed to perform a given contraction. In other words the innervation of each fiber depends solely on the muscle needed to engage in a specific exercise. By first knowing the anatomy behind a muscle cell one can then have a better understanding of the effects training has on muscle cell hypertrophy.
The two primary functions of skeletal muscle is to contract to cause force, and to provide stability to the body. During exercise each muscle must be able to contract in response to the stress or tension on that muscle. The idea behind muscle hypertrophy is that as a progressive overload of stress is applied to the muscle, it is able to adapt by increasing the size and number of contractile proteins making up the muscle fiber.
