Olympic swimmers are often seen sporting coats, from lightweight zip-ups to hefty puffers, before diving into the pool. This practice might seem counterintuitive, but there’s a science-backed reason why these athletes bundle up before competitions. It all comes down to maintaining optimal body temperature for peak performance.
The Importance of Warm Muscles for Swimmers
A proper warm-up is crucial for any athlete, and swimmers are no exception. Warming up increases blood flow and oxygen delivery to muscles, preparing the body for intense exertion. This physiological preparation is essential for achieving top speed and endurance in the pool. But why coats specifically?
Coats Help Maintain Core Temperature
While movement-based warm-ups are standard, maintaining core body temperature plays a significant role in performance. A slightly elevated core temperature helps muscles function more efficiently. Coats trap heat generated by the body during warm-up exercises, preventing a drop in core temperature before the race. This is especially important in a cool pool environment where body heat can be lost quickly.

The Performance Boost of Warm Clothing: Evidence from Research
A study published in the European Journal of Sport Science found that competitive swimmers who wore warm clothing between their warm-up and race performed approximately 0.6 percent better than those who wore minimal clothing. While seemingly small, this margin can be decisive in the Olympics, where fractions of a second can separate medalists from the rest of the field. In a sport where victory is often determined by hundredths of a second, a 0.6 percent advantage can be the difference between gold and silver.
Popular Warm-Up Jackets Among Olympic Swimmers
Olympic athletes often opt for specialized warm-up jackets designed for optimal heat retention. Katie Ledecky, a renowned Olympic swimmer, has been seen wearing the TYR Sport Hydrosphere Women’s Softshell Recon Jacket. This jacket features a slim profile with a fleece interior for insulation. The design allows for freedom of movement while effectively trapping warmth.

The TYR Hydrosphere Men’s Mission Puffer Jacket, with its fleece-lined pockets, elastic cuffs, and adjustable hood, is another popular choice among male Olympic swimmers. This heavier jacket provides maximum warmth in colder environments, ensuring muscles remain at their optimal temperature.
Conclusion: Warmth Equals Winning?
While wearing a coat might not guarantee a gold medal, it’s a strategic practice employed by Olympic swimmers to optimize their performance. Maintaining core body temperature through the use of warm clothing can provide a slight but potentially significant edge in a highly competitive sport. The science supports the strategy, and the results speak for themselves. Staying warm helps swimmers stay ready to win.
