In the last post we talked about the benefits of swimming and the different exercises you can do in the pool. Today we are going to talk about ways to improve your swim stroke in order to avoid injury.
According to Move Forward PT shoulder injuries are a very common injury in swimming. The good news is that with the proper swim stroke they are preventable. Here are the five tips for improving your swim stroke:

1. Bilateral Breathing
The ability to breathe comfortably on both sides is important while swimming the freestyle stroke. By changing sides, you are equalizing muscle development and achieving symmetry. It also allows for smoother and more even strokes. It may feel awkward on one side at first. With consistent practice, it will become more natural and lead to a more efficient stroke.

2. Posture
Your posture out of the pool can affect your posture in the pool. If you have tightness in the chest muscles or rounded shoulder posture, this can put you more at risk for shoulder impingement. The shoulders should be back and the chest forward during a freestyle stroke. Shoulder impingement occurs when the tendons become pinched, irritated, and inflamed in the shoulder region. Position of the head while swimming should be looking forward and down, so the water will crest above the eyebrows.

3. Kick
The kick should originate from the hips. In other words, “kick your legs,” don’t kick your feet. There should be a slight bend in your knee at all times. Your toes will naturally point.

4. “Catch and Pull”
The “catch” is when the hand enters the water. You are essentially “catching” the water, with the third or fourth finger leading the arm, with your wrist slightly bent at the line of your goggles. If the thumb enters the water first, it can cause the shoulder to internally rotate and can lead to a shoulder injury. The “pull” is the sweeping phase when the arm pulls through the water to move the body forward. The hand and arm should enter the water as an extension of the shoulder. If the arm crosses over the midline or is too wide, it could cause shoulder injury.

5. Body Rotation
Your body should rotate as if your spinal column is a skewer. As the right arm enters the water, the body should rotate slightly toward the right, and vice versa. A flat body posture also can lead to shoulder Injury. Body rotation also facilitates bilateral breathing.
In addition to the above tips, proper warm-up and stretching exercises are important to reduce injury during swim sessions. Strength training to the shoulder, particularly the rotator cuff, scapular, and core muscles, will enable you to have a more powerful end efficient stroke. Once you are proficient in swimming freestyle, you can learn other strokes. Alternating different strokes prevents repetitive motion that can lead to overuse injuries.
