McLeod - Swimming Anatomy - 2010

Muscles Involved

Primary:Anterior deltoid, middle deltoid

Secondary:Pectoralis major, posterior deltoid, trapezius, supraspinatus, triceps brachii

Swimming Focus

To maximize the distanced gained during each stroke, you need to be able to enter the water with your arm or arms extended and your body in an elongated position. This exercise helps develop overhead strength and confidence in extending your reach when entering the water.

The exercise described here is a modified version of the military press motion performed in traditional weight lifting. The traditional version is usually performed with the dumbbells held in the "stick 'em up" position, with the palms rotated outward. Swimmer should avoid this position because it can place undue stress on the shoulders and could be detrimental when combined with the stress already present from the yardage load in the water.

ASAFETYTIP

Because ofthe overhead nature ofthe exercise, young swimmers who may not have the strength and coordination to control the movement should not perform

it. Ifyou are currently experiencing shoulder pain or have a recent history of it, you should follow the 90/90

rule when performing this and other upper-extremity exercises. The 90/90 rule states that you should avoid dropping your shoulder below 90 degrees ofabduction or flexion and avoid flexing your elbow more than 90 degrees.

Execution

1 . Standing with a flat back, bend forward at your waist until your back is near parallel to the ground.

2.With your arms hanging, hold the dumbbells so that your palms face in.

3.Keeping your arms straight, raise the dumbbells in an arcing motion until your elbows are level with your shoulders.

4.Resisting gravity, slowly return to the starting position.

Muscles Involved

Primary:Rhomboid major, rhomboid minor, posterior deltoid Secondary:Trapezius, infraspinatus, teres major, teres minor

Swimming Focus

This exercise can have two points of emphasis depending on the weight of the dumbbell used. Using lighter weights allows you to concentrate more on pinching the shoulder blades together at the end of the exercise, thus focusing on recruiting the rhomboid major and rhomboid minor. This is an effective way to target the rhomboids to improve their role as a dynamic stabilizer of the shoulder blades, which in turn will increase the foundational strength of the shoulder blades and decrease the risk of injury. As the weight increases, the emphasis shifts from the rhomboids to the posterior deltoid along the back of the shoulder. Targeting either of these muscle groups with this exercise will transfer to strengthening the recovery phase of breaststroke and butterfly, as well as contribute to the initial portion of the recovery during freestyle.

ASAFETYTIP

Be sure to keep your head in line with your back when performing this exercise. Lifting your head will lead to arching ofthe low back, and dropping your head will cause rounding ofthe upper back. Either motion can place unnecessary stress on the low to mid-back.
