What Do High Level Athletes Know About Floating?
Here’s a sports trivia question for all our athletically-inclined readers:
What do the Dallas Cowboys, the Golden State Warriors, the Chicago Cubs, The Manchester United Football Club, and Michael Phelps all have in common?
You might see this lineup and think “well, the ‘92 Dallas Cowboys won the Superbowl that year, the Golden State Warriors won the NBA Finals in ‘14, the Cubs made history when they won the 2016 World Series, Manchester United is one of the most hono(u)red Football Clubs in the world, and Michael Phelps has won more gold medals than any other Olympian in history! They’re all winners!”
But that’s not all they have in common: they also all used float tanks.
They weren’t alone, either: the New England Patriots, UFC Hall of Famer Royce Gracie, the Chicago Bulls, Olympic Gymnast Aly Raisman, the Philadelphia Eagles, Olympic Gold Medalist Carl Lewis, The Detroit Pistons, as well as literally hundreds of other professional athletes have incorporated floating into their training and recovery programs throughout the years.
Floating is one of the best kept secrets in high-performing athletes and there’s some interesting research that helps explain why.
Raising the Performance Ceiling
If someone told you that laying in the dark on a bed of saltwater could give you superhuman strength or speed, would you believe them? It may not be as far-fetched as it sounds.
One study found that high-level athletes who have plateaued – those who don’t see any additional benefits from more training – would see an improvement in performance after floating in conjunction with visualization techniques, even without additional training.
Put another way, athletes were able to increase their peak performance just by floating before competition. A followup study not only confirmed this result but also showed that floating multiple times between games led to significant improvements over a single float! This demonstrates something that most floaters already know: the more you float, the better it is for you.
Improved Precision
Beyond general athletic performance, a few studies looked at more specific benefits of floating in athletes.
Several studies tested how floating affects marksmanship. All 3 studies had a float group and a control group, with participants from all skill levels.
In the rifle marksmanship study 75% had a statistically significant increase in accuracy pre- to post-float with no such increase was found in the control group (relaxation without floating). A similar effect was found in the darts study, with 80% of participants seeing an improvement. It’s worth noting that in both studies, these improvements were seen regardless of skill level.
While the archery study didn’t see any significant increase in accuracy, it did show that the float-group had more consistent scores than the non-float group, something that the other two studies found as well.
Reduced Recovery Time
While the benefits described above could be explained as a side effect of stress reduction, there’s more to the story of the impact on floating in physical performance, certainly not enough to explain why floating has been so popular among high-level athletes.
Building off of earlier research, scientists in recent years have started using biometrics to see what’s happening to athletes who float on a physiological level. A 2013 study looked at the effect floating has on lactic acid build-up.
Lactic acid is associated with that post-workout feeling of tightness in your muscles that causes your body to stiffen and get sore. Professional athletes are always looking for new ways to reduce the amount it builds up during a workout to maximize performance.
What they found was that floating after exercise showed a 62% reduction in lactic acid buildup on average compared to the control group. Participants also reported feeling less pain and were back at peak performance sooner.
A followup study in 2016 was able to replicate this effect with a larger sample size over 9 different sports. Not only were they able to replicate the lactic acid reduction, they also found a significant reduction in muscle soreness and improved mood and reduced fatigue in those that floated.
Looking at the Whole Picture
When you take all of these effects together, you can start to see why floating has been one of the best kept secrets of successful athletes. When you take into consideration the stress reduction benefits as well, you can see how floating might help them be at the top of their mental game in addition to their professional one.
The best part about all of this? Floating is helpful for athletes at every level. You don’t need to be an Olympian to see the benefits of floating in your exercise. It can be a nice way to cool down after a jog or help you recover after playing in a local league game on the weekends.

Whoop Experiment
So, last week I conducted an experiment on myself. Using my Whoop performance monitor, I wanted to see the effect that floating 5 days in a row would have on my sleep and recovery. In the photos below, you can see my sleep quality and recovery leading up to the floats. Not very good, is it?
The next 6 slides show recovery and heart rate during the float, as well as heart rate during sleep that evening.
We’ll mostly focus on the correlation between heart rate variability (HRV) and recovery here. Now, heart rate variability is “simply a measure of the variation in time between each heartbeat. This variation is controlled by a primitive part of the nervous system called the autonomic nervous system (ANS). It works regardless of our desire and regulates, among other things, our heart rate, blood pressure, breathing, and digestion. The ANS is subdivided into two large components, the sympathetic and the parasympathetic nervous system, also known as the fight-or-flight mechanism and the relaxation response.” (https://www.health.harvard.edu/blog/heart-rate-variability-new-way-track-well-2017112212789)
Basically, the higher the HRV, the better recovery. Now during a float, the environment greatly reduces the demand on the ANS. Heart beat naturally slows down as the body has no demands placed on it, blood pressure reduces with the removal of external stress, and breathing gets into a steady rhythm. Looking at the slides above, it becomes apparent that HRV and recovery go hand in hand. Here’s a short breakdown of the data:
Non float day averages: Float day averages:
HRV - 120 HRV - 141.4
Recovery - 55.9% Recovery - 73%
Sleep quality - 70% Sleep quality - 74.2%
Sleep length - 6:29 Sleep length - 6:57
Strain - 12.58 Strain - 15.8
Low/high for non float days: Low/high for float days:
HRV - 77/163 HRV - 123/159
Recovery - 23/89% Recovery - 58/87%
Sleep quality - 60/74% Sleep quality - 66/89%
Sleep length - 5:39/7:02 Sleep length - 5:57/7:25
Strain - 8.6/14.7 Strain - 13/17.6
To break that down a little more, over the 5 days we saw:
HRV increase of 21.4
Recovery increase of 17.1%
Sleep quality increase of 4.2%
Sleep length increase of 28 minutes
Strain increase of 3.22
Now here’s where it gets really interesting. With only 30 minutes total more sleep over the course of the 5 float days (a measly average of 6 minutes per night!), there was a substantial increase in quality and recovery. And that’s taking into account more strain that the body was able to take through exercise. There were a few unforeseen variables, like noisy neighbors and my 4-year-old crawling into my bed that disturbed the sleep a little, but that’s life.
We all have stress in our lives, and there are many ways of dealing with it. Whether it be emotional, physical or both, we can’t just ignore it and hope it goes away. One of the greatest aspects of floating is that it’s completely noninvasive, and there are no harmful side effects. Essentially, it’s nothing at all. Just you, by yourself, having an opportunity to remove all the external stressors that make life less enjoyable. Aside from the benefits of reducing stress, regular floats are tremendous for sleep quality, which of course is critical for immune system, mood, and just keeping your body and mind working at its best.
