Creatine for Swimmers: What You Need to Know

When it comes to supplementation for swimmers there are fewer performance aids that cause more confusion and hype than creatine. Long shown to provide gains in muscle mass and increased recovery, short term studies have found that creatine can help boost performance in the water.

Here is what you need to know about creatine for swimmers.

Florent Manaudou created a bit of a stir when he acknowledged back in 2014 that he had been taking creatine regularly since 2011. It was at that point, during his arrival at the vaunted Marseilles program, where the senior swimmers on the team told him that creatine was not a prohibited substance.

And while most elite level swimmers won’t necessarily jump to admit that they take it, I have seen it administered at both the club level and with even junior level swimmers over my years on the pool deck.

Creatine for Swimmers: What You Need to Know

And yet, the prospect of being able to swim faster for longer taking what is one of the cheapest supplements on the market is understandably enticing.

Creatine for Swimmers: The Research

Here is what the ladies and gents in the white lab coats have discovered over the years about how creatine affects swimmers:

  • One study took a group of swimmers and had them perform a 50 yard all out sprint, in addition to 8×50 all out @1:30 before and after they supplemented with 9g of creatine per day. The swimmers who took creatine performed the same as the control group in the 50-yard dash, but improved on the repeated sprint set, with the times tapering off more slowly for the swimmers that took creatine.
  • This study of 16 female swimmers showed that while 21 days of 20g of creatine per day didn’t increase overall swimming performance that there were significant increases in swimming efficiency after the period of supplementation. One of the things creatine is known for is bloating; this study found that there were no differences in body weight and composition between the creatine group and the control group.
  • Similar to the first study mentioned, a faster swimming velocity was held in sprints of around 30 seconds, where as 10-15 second sprint times were not effected. This two week study of university-aged swimmers had them performing 10×25 yard and 6x50m interval sets; only the men in the study showed improvement, and only in the interval rounds.
  • This research took 20 age group swimmers (10 male, 10 female) and had them load up on creatine for 27 days. And while swimmers didn’t improve sprint performance in the water, they did increase power output on a swim bench versus the placebo.

As you can see, the research isn’t even unanimous, although it is pretty consistent in pointing towards creatine being an aid for swimmers. (I should also re-emphasize that these are all short term studies.)

So is it right for you?

The answer, as it always does, completely depends.

The 3 Key Things You Need to Know About Creatine

1. Everyone responds differently, from hardly at all to really well.

This is one of those areas where genetics play a pivotal role; creatine supplementation (just like any kind of stimulus or training program) affects athletes in different ways.

One study of weightlifters found that increases in strength gain ranged from 3 to 45%. That’s a huge range!

It’s no different from swimmers; how you respond will come down to hereditary factors and muscle mass.

2. It is not going to replace the fundamentals of your training.

If you are not getting a full night of rest, and you are not eating well, supplementing with creatine won’t replace those recovery deficiencies. It’s not a band aid, and it can’t replace the fundamentals of your swimming.

It is what it is—a supplement. A bonus when you’ve got your other bases covered.

3. USA Swimming does not recommend it as a supplement for their swimmers.

They are pretty clear on their stance on creatine for swimmers:

USA Swimming would never recommend a swimmer (of any age) take creatine. There is really no evidence that it would be beneficial for the type of training our athletes do [in and out of the water] and there is obviously a lack of long-term studies.”

The Takeaway

So is creatine right for you?

Maybe, but know this: The performance gains you will experience from sleeping an extra hour per night will far outpace the gains you *might* get from taking creatine. And it’s also cheaper and the whole being fully-rested thing will leave you feeling a lot less crabby.

Before taking any supplements do your research, and sit down with your coach and medical practitioner before you move forward. Always.
