The 50-meter freestyle is the most chaotic, adrenaline-fueled event in all of swimming. It is a pure, unadulterated display of explosive power. Unlike an open water marathon where pacing and strategy rule the day, the 50 freestyle is a drag race. If you miss your start, glide too long on your breakout, or take one breath too many, the race is over.
Many swimmers make the critical mistake of training for the 50 free the exact same way they train for a 200 free, just “swimming harder.” This does not work. Sprinting is a completely different physiological discipline. It requires specialized mechanics, extreme anaerobic tolerance, and gear that cuts through the water like a razor.
At OpenWaterGoggles.com, we know that speed is the ultimate goal. Drawing on data from the world’s fastest athletes and elite coaching blueprints, we are breaking down the absolute essentials of sprinting. Here are 5 training hacks to completely transform your 50 freestyle sprint and leave your competition in your wake.
1. The “No-Breathe” Rule (Anaerobic Dominance)
Have you ever watched an Olympic 50m freestyle final? You will notice something terrifying: the athletes almost never breathe.
Here is the brutal truth of sprinting: breathing slows you down. Every time you rotate your head to take a breath, you slightly drop your opposite hip, disrupt your hydrodynamic streamline, and momentarily pause your pulling arm. Elite sprinters train to eliminate this entirely.
The Training Hack: You must build your hypoxic (low oxygen) tolerance. Incorporate “no-breathe” 25-meter sprints into your daily warm-up. Challenge yourself to swim 50 meters taking only a single breath at the 25-meter mark. Your lungs will burn, but your times will plummet.
2. Master the Underwater Dolphin Kick
The fastest you will ever move in a swimming race is the exact moment you leave the starting block. Your goal is to carry that momentum for as long as legally possible.
Under competitive rules, you are allowed to stay underwater for 15 meters. Swimming entirely submerged in a tight streamline while executing a powerful, whip-like dolphin kick is drastically faster than swimming on the turbulent surface. The 50 freestyle is often won and lost in the underwater phase.
The Training Hack: Equip yourself with a pair of short training fins. Practice pushing off the wall and executing 6 to 8 massive, rapid dolphin kicks before breaking the surface. The power must originate from your chest and core, not just your knees.

3. Maximize Your Stroke Rate (Turnover)
In distance swimming, coaches preach “Distance Per Stroke” (DPS)—gliding long and efficiently. In the 50 freestyle, DPS is thrown out the window. Stroke rate (how fast your arms rotate) is king.
Elite sprinters look like windmills. They catch the water early and aggressively rip their hands through to their hips, minimizing any “dead spots” or gliding phases in their stroke. You must train your fast-twitch muscle fibers to fire at maximum capacity.
The Training Hack: Use a waterproof metronome or a premium GPS swim watch that features a tempo trainer. Set the beep to an aggressively fast pace (e.g., 0.8 seconds per stroke) and fight to keep your arms matching the rhythm.
4. Build Raw Pull Power on Dryland
You cannot build a blistering 50 freestyle sprint solely in the water. As we discussed in our ultimate dryland training guide, you need raw, load-bearing resistance to build explosive latissimus dorsi and triceps power.
The Training Hack: Swim parachutes and resistance stretch cords are mandatory for sprinters. Tying a small drag parachute to your waist and sprinting 25 meters forces your upper body to recruit every single muscle fiber just to move forward. When you take the parachute off, you will feel like you are flying.

5. Gear Up: Low-Profile Racing Goggles
When you dive off the starting block, you hit the water at immense speeds. If you are wearing bulky, open-water masks, the force of the water will rip them off your face, filling your eyes with chlorine and destroying your race.
Sprinters require elite, low-profile racing goggles. These goggles sit deep inside the orbital socket to minimize hydrodynamic drag and provide a razor-sharp, locked-in fit.
The Ultimate Sprint Goggle: The Arena Cobra Ultra Mirror Swipe is the undisputed weapon of choice for sprinters. Its blade-like profile cuts through the water, the extended side-temples maximize stability during the dive, and the mirrored finish hides your eyes from competitors in the ready room. It is pure, unadulterated speed gear.

The Final Verdict: Unleash the Beast
The 50 freestyle is not for the faint of heart. It requires you to push your body into deep oxygen debt, ignore the burning in your lungs, and violently attack the water from the beep to the wall.
Stop gliding. Start sprinting. Master your underwater dolphin kicks, build your raw power with resistance parachutes, lock in your Arena Cobra Ultra goggles, and prepare to shatter your personal bests.
Why do elite sprinters not breathe during the 50 freestyle?
Breathing fundamentally slows you down. Every time you turn your head to breathe, you disrupt your body’s horizontal alignment, drop your hips, and lose a fraction of a second in your stroke cycle. In a race decided by hundredths of a second, elite sprinters train their anaerobic capacity to complete the entire 50 meters with zero or one breath.
Is stroke rate more important than distance per stroke in a sprint?
For a 50 freestyle, stroke rate (turnover) is king. While distance per stroke is crucial for efficiency in long-distance open water swimming, sprinters must maximize their turnover rate. The goal is to apply maximum explosive power in the shortest amount of time without completely slipping through the water.
How far should I dolphin kick off the start?
Under competitive rules, you can underwater dolphin kick for up to 15 meters. Water is 800 times denser than air, but swimming completely submerged in a tight streamline is significantly faster than swimming on the turbulent surface. Mastering the underwater dolphin kick is the ultimate sprint advantage.
What is the best type of goggle for sprint freestyle?
You need low-profile racing goggles, such as the Arena Cobra Ultra or Speedo Vanquisher 2.0. They sit deep inside the eye socket to minimize hydrodynamic drag and are engineered to stay glued to your face when you hit the water at high speeds off the starting block.
