Space Innovations that Propel Swimmers Faster

Delivering values from space
Space exploration isn't just about rockets and distant planets. Many of the technologies developed for space have trickled down to benefit our everyday lives, including the world of professional sports.
In the high-stakes arena of elite athletics, even the tiniest advantage can make the difference between victory and defeat. Take the men's swimming 100-meter freestyle final at the Paris 2024 Summer Olympics. Pan Zhanle shattered the world record with a time of 46.40 seconds, while athletes in second through fourth place were separated by a mere 0.01 seconds.
While Olympic swimmers and astronauts may seem worlds apart, they share a common challenge: overcoming the drag that slows them down. This shared hurdle has led to the development of innovations that improve both spaceflight and swimmers' performance.
The intensive research and studies upon fluid dynamics by NASA’s Aeronautics Research Mission Directorate do lead to making spaceflight becoming more safer and reliable. These findings also contribute to multiple great spinoffs for daily life usage, as well as improving the performance of elite-level athletes.
One of the well-known use cases is the Speedo’s swimsuit, where the Los Angeles-based brand collaborated with Lamoral, a Dutch company with expertise in satellite coating to protect from space radiation. This coating was engineered into the Speedo’s Fastkin LZR swimsuit, introduced in late 2023, to reduce the water absorption of the suit’s fabric and increase its water repellence by 6 times compared to the older generations.
Moreover, the swimsuit also uses a lightweight fabric, which provides a feeling of weightlessness-like for athletes. Astronauts also train for their spacewalk underwater, which provides a neutral buoyancy simulation like being in the microgravity environment in orbit. But most importantly, lighter mass also means better time for professional-level athletes.
Space innovations and spinoffs were part of the historic record-breaking swimming event at the 2008 Summer Olympics in Beijing, China. Speedo's LZR Racer, which was designed in collaboration with NASA to reduce drag up to 24%, and help provide extra compression in key areas to help reduce energy required for swimmers, was responsible for breaking 24 world records at the National Aquatics Centre.
The hydro-dynamic full-body swimsuit was so efficient that it has since been banned by World Aquatics, as the suit could be one form of ‘mechanical doping’, creating an uneven field of competition.
The story of Olympic swimsuits underscores the far-reaching benefits of space exploration. Beyond expanding our knowledge and understanding of the universe, space technologies, and their spinoffs continue to improve life on Earth, pushing the boundaries of human potential and inspiring athletes to achieve extraordinary feats.
