Muscular System In Swimming

Muscular system is a system which consists of specialized cells which called as muscle fibers. The main function of muscular system are allows the body movement, circulates the blood throughout the body, helps to maintain the posture such as standing and sitting and also function as heat production which helps to maintain the body temperature. Human body would not able to move at all without muscles. In human body there are more than 600 muscles and most of the muscles attached to the skeleton. Muscle system can be divided into three types of muscles which is the cardiac muscle, skeletal muscle and also smooth muscle. There are two type of muscle arrangement which is the antagonistic muscles and synergistic muscles.

Each style involved various muscles such as biceps, triceps, deltoids, pectoralis, sternocleidomastoid and many more. Freestyle swimming stroke involves more muscles compare to other style stroke. Backstroke is similar to the freestyle stroke.

Muscles involved in freestyle and backstroke are the arm’s muscles which is the brachioradialis (forearm flex muscle), thenars (hand muscle), biceps, flexor digitorum profundus (forearm extend muscle), triceps and deltoids (shoulder muscle). In addition, the neck muscles (sternocleidomastoid) do involved too. As for the leg muscles the harmstrings, digitourm brevis (foot muscle) and tibialis anterior (shin muscle) are involved in swimming activity. Finally, the abductor magnus(groin), rhomboid major and minor, latissimus dorsi (back muscle) and external oblique.

Muscles that have been mention above have circled in the picture below. There are 24 types and locations of muscles have been circled in this figure. The blue circles are the primary muscles and the black circles are the secondary muscle used to worked and
