Swimming is one of the most popular sports in the world. We swim in the sea, pools, lakes, streams, rivers and even ponds.
And while swimming is considered a ‘low-impact’ sport due to the fact that the water supports a large percentage of, more than 84% of regular swimmers suffer from some type of overuse type injury caused by swimming.
Why? The main reason is the high repetition number and forceful nature of the shoulder revolutions which takes our shoulder joint through its full range of motion (which is one of the greatest of all our joints), against resistance, over and over again.
And as 50-90% of the power generated to propel you forward comes from the shoulders, you can see why they are the most frequently injured joint.
However, swimming also puts stress on your back, to hold you level in the water; on the neck when raising your head out of the water to breathe and if you favour breaststroke as a stroke, there’s added pressure from the unnatural twisting motion on the knees.
So, despite it seeming to be a low-impact sport, swimming actually carries a surprisingly high risk of injury. Swimming injuries generally stem from two sources, and often these sources will combine:
- Muscle imbalances
- Stroke technique issues
Our everyday posture, particularly if you spend a lot of time sitting at desk or in a car, or generally not moving around, creates all sorts of muscle imbalances from short hamstrings, tight muscles around the neck, back and shoulders. We unconsciously adopt a curved forward upper back, round shoulders and chin poke, which not only add to shoulder problems in swimmers but neck pain too.
Poor posture is the biggest culprit of short tight trapezius and pectoral muscles and weak anterior (front) neck and upper back muscles. These muscles can be painful and develop trigger points which are hyperactive spots in the muscle, commonly referring pain and causing headaches. Tight muscles may also limit your neck movements. Good posture ensures good alignment of the joints and ligaments which allows for optimal contraction of your muscles and off-loads underlying structures.
This a big topic to cover because it depends what stroke you’re swimming mostly with and what kind of injury you may have but issues include: a wide, swinging arm recovery which requires excessive internal rotation, causing impingement on the joint; thumb in first with hand entry, which again causes excessive internal rotation in the shoulder and a dropped elbow or straight arm pull through which creates a long lever and overloads the shoulder.
The bottom line is that the benefits of swimming – whether it’s for general fitness and physical activity, the desire to win competitions, or just to find your quiet place for stress relief – far outweigh the risk of injury.
