Swim For Triathlon

Dear Friend,

Swimming is a great sport in that there aren’t many injuries.

Shoulders tend to be the main grievance among competitive swimmers and triathletes, however.

I recently got back from a 2.5 month trip out of the country where I did very little swimming. I’m now in the midst of getting back into swimming shape. For 15+ years I have had a shoulder that acts up, especially if I’m trying to make a swimming comeback!

There are a few causes of swimming injuries. Check out today’s article on shoulder injuries, which includes some tips that can not only prevent them, but can improve your technique and speed at the same time!

Swimming and Shoulder Injuries

by Kevin Koskella

Most sports come with injuries to accompany them. Although swimming is, by most standards, not a sport associated with high risk of injury, it does have it’s own problems. By far the biggest source of sidelining swimming injuries is the shoulder.

I was a competitive swimmer for 14 years, sometimes doing double workouts and 15,000 meters per day. I swam mostly freestyle and backstroke. I never had a shoulder problem until my college years. I had been training with pull buoy and paddles throughout my freshman year of college. At this point, I started getting a little pain in my left shoulder, but being 19 and feeling invincible, I swam through the pain and was sure that a little rest
after the season would fix me right up. Well I did take the rest and ended up in a lot more pain when I resumed swimming a few months later!

The doctors said it was rotator cuff tendonitis. I rehabbed and within a few more months I was back to swimming every day, but my shoulder has never been the same since.

There are a variety of ways to give yourself a shoulder injury in swimming. “Overuse” is often what doctors and trainers will say. This is a pretty general term and doesn’t help many athletes when they’re trying to accomplish their goals and avoid getting hurt!

Some of the other ways to wreck your shoulder(s) include:

  • Improper Technique- reaching too far and over-rotating, crossing over in freestyle when pulling
  • Sudden increase in training distance or intensity
  • The use of pull buoys and hand paddles
  • Swimming only freestyle at every workout
  • Unbalanced strength development

Preventative Measures

1. One of the most important things in stroke technique when it comes to freestyle and avoiding shoulder injuries is to bend your elbows underwater during the pull. This is proper form and will keep you from putting your shoulder in an awkward position that leads to a rotator cuff problem.

2. When you’ve had some time away from swimming and are resuming training, always ease back into it. If, for example, you train with weights and had a 3-month layoff, you wouldn’t try to max out on your bench press the
first day back. The same applies to swimming. Instead of jumping back in and resuming the 5,000 meters you were doing before your break, start with something very light, like 1000 the first day, 1200 the next, etc.

3. Avoid the use of pull buoys and paddles. Although it is tempting, buoys merely give you a false sense of flotation and put unnecessary tension on
your joints, especially your shoulders. Although there are paddles designed not to cause shoulder problems, most of the paddles out there are not needed in training, and will cause shoulder problems if you give it enough

4. Swimming only freestyle at all of your workouts may seem like a good idea if you are training for a triathlon, but I would not recommend it. First of all, you will gain more from cross training with other strokes. And most importantly, excess in any one stroke leads to a higher probability of an overuse injury.

5. If you breath to only one side, you will develop the muscles more on one side than the other, and this could cause a breakdown and a shoulder problem. Incorporate bilateral breathing into your workouts to avoid this. If
it’s extremely awkward at first, start with just breathing bilaterally in warm up and warm-down, and slowly add it into the rest of your workouts as it becomes more comfortable.


If you are just getting over a shoulder injury and are jumping back in the pool, put on a pair of fins. Zoomers or Hydro Finz work the best. That way you are accomplishing 3 things: 1) taking some pressure off your shoulders, 2) getting a great cardiovascular workout, and 3) building
strength in your legs for swimming.

One “good” thing about shoulder injuries is that they force us to slow down, and give us a chance to work on drills and stroke technique while we get back to health. And from what I’ve seen as a coach, many triathletes can use a little slowing down when it comes to improving their swimming!
