  2. Muscles Used If the swimmer uses proper technique and form, nearly every muscle in his or her body will be used.

  3. Muscle Group: Abdominals No matter what stroke a swimmer does, the “core” muscle group must always be engaged to insure proper form. The muscles are • Pectoralis major (origin: sternum; insertion: humerus • Rectus Abdominis (origin: pubis; insertion: ribs) • External and Internal Obliques (origin: lower 7 ribs and lumbar spine; insertion: ilium and pubis) • Transverse Abdominis (origin: rectus sheath; insertion: lumbar spine and lower ribs)

  4. Muscle Group: Head and Neck Proper head and neck position determine the efficiency of the swimmer’s performance; if the head is lifted, the hips drop creating additional drag and thus slowing down the swimmer. While nearly all the muscles in the head are involved in swimming, the most important are the Trapezius (origin: back of skull and vertebrae; insertion: scapula and clavicle) and the Sternocleidomastoid (origin: sternum and clavical; insertion: skull).

  5. Muscle Group: Upper Extremities Without the use of the muscles in the arm, stroke swimming would not be possible. Most important: Biceps (origin: scapula and clavicle; insertion: radius) and Triceps (origin: humerus; insertion: ulna)- pull the water past the swimmer. Deltoids (origin: clavicle and scapula; insertion: humerus) and Brachioradialis (origin: humerus; insertion: radius)- stabilize the arm during the stroke.

  6. Muscle Group: Lower Extremities The muscles in the legs are very important in competitive swimming. These muscles give the swimmer a great amount of momentum as he or she dives off the blocks and as he or she pushes off of the wall in a flip/ open turn. Key Muscles: • Gluteals (origin: Ilium; insertion: femur) • Hamstrings (origin: pelvis; insertion: tibia) • Quadriceps- multiple muscles (origin: femur and pelvis; insertion: fibula and tibia) • Gastrocnemius (origin: femur; insertion: heel)

  7. Joints, Tendons and Ligaments Swimming is one of the best sports to do for one’s joints- keeps the joints flexible (i.e. ligaments are kept limber) and little impact is put on the joints and bones. Improper Technique, however, can lead to tendonitis (inflammation of the tendon), especially in the shoulder.
