Hypoxic training, also known as breath control training, is an advanced swimming technique used to improve lung capacity, enhance oxygen efficiency, and build mental toughness. While hypoxic training isn’t for beginners, it’s an excellent tool for advanced freestyle swimmers looking to maximize performance and gain a competitive edge.
This post will explore the benefits, risks, and techniques of hypoxic training, and provide detailed breath control drills designed to challenge and improve your freestyle swimming.
What Is Hypoxic Training?
Hypoxic training involves reducing the frequency of breaths during swimming to simulate oxygen deprivation. This technique forces your body to adapt to limited oxygen, enhancing its ability to use oxygen efficiently and improving overall endurance.
Key Benefits:
Increases Lung Capacity: Expands the lungs' ability to hold and use oxygen.
Boosts Aerobic Efficiency: Improves how your body processes and delivers oxygen to muscles.
Enhances Mental Toughness: Builds focus and resilience by challenging you to push through discomfort.
Improves Technique: Encourages smoother and more efficient strokes to conserve energy.
Who Should Practice Hypoxic Training?
Advanced swimmers with solid technique and experience in endurance swimming.
Athletes training for competitive events, triathlons, or open-water swims.
Swimmers looking to improve underwater skills for starts and turns.
Safety Considerations for Hypoxic Training
Avoid Overexertion: Monitor your body and stop if you feel lightheaded or dizzy.
Train Under Supervision: Practice in a pool with a lifeguard or a coach present.
Gradually Increase Intensity: Start with short intervals and build up as your tolerance improves.
Be Aware of Shallow Water Blackout: A dangerous condition caused by holding your breath for too long. Always prioritize safety.
How to Incorporate Hypoxic Training into Your Routine
Warm-Up: Always begin with a proper warm-up to prepare your lungs and muscles.
Start Small: Reduce breathing frequency gradually to allow your body to adapt.
Combine with Technique Work: Use hypoxic drills to improve stroke efficiency and streamline position.
Limit Sessions: Perform hypoxic training 1–2 times per week to avoid overtraining.
Breath Control Drills for Advanced Freestyle Swimmers
1. 3-5-7 Breathing Pattern
How to Do It: Swim freestyle while alternating breathing every 3, 5, and 7 strokes.
Focus: Gradually increases the time between breaths, enhancing lung capacity.
Set Example:
4x50m freestyle: 1st 50m breathe every 3 strokes, 2nd 50m every 5 strokes, and 3rd 50m every 7 strokes.
Rest 20 seconds between sets.
2. Pyramid Breathing Drill
How to Do It: Start with breathing every 3 strokes, then increase to 5, 7, and 9 strokes, and then return back down.
Focus: Builds breath control progressively while maintaining stroke efficiency.
Set Example:
1x25m every 3 strokes
1x25m every 5 strokes
1x25m every 7 strokes
1x25m every 9 strokes
Reverse the pyramid on the next set.
3. Hypoxic Sprint Intervals
How to Do It: Perform 25m sprints with a reduced breathing pattern, such as breathing once or not at all.
Focus: Enhances explosive power and builds anaerobic capacity.
Set Example:
8x25m sprints, breathing once or not at all, with 30 seconds rest between sprints.
4. Underwater Dolphin Kicks
How to Do It: Push off the wall and perform dolphin kicks underwater as far as possible before surfacing.
Focus: Improves breath control, core strength, and streamline efficiency.
Set Example:
6x25m underwater kicks, aiming to reach 15 meters or more before surfacing.
5. Descending Breath Control Drill
How to Do It: Swim 100m freestyle, decreasing the number of breaths per 25m segment.
Focus: Trains your ability to hold your breath for longer intervals as you fatigue.
Set Example:
1st 25m: Breathe every 3 strokes
2nd 25m: Breathe every 5 strokes
3rd 25m: Breathe every 7 strokes
4th 25m: No breathing if possible
6. One-Arm Freestyle Breathing Control
How to Do It: Swim freestyle using one arm while reducing your breathing frequency. Alternate arms every 25m.
Focus: Builds efficiency and strengthens body rotation.
Set Example:
4x50m with breathing every 5 strokes, alternating arms.
Sample Hypoxic Training Session
Warm-Up (10 Minutes)
200m freestyle (easy pace)
100m backstroke
100m freestyle with bilateral breathing
Main Set (30 Minutes)
6x50m 3-5-7 breathing pattern (rest 20 seconds between sets)
4x25m underwater dolphin kicks (rest 30 seconds between sets)
8x25m hypoxic sprints (breathe once or not at all, rest 30 seconds)
4x100m descending breath control drill (rest 45 seconds between sets)
Cool-Down (10 Minutes)
200m freestyle with relaxed bilateral breathing
100m choice stroke (easy pace)
Tips for Successful Hypoxic Training
Stay Relaxed: Tension in your body increases oxygen demand. Stay calm and maintain a smooth stroke.
Focus on Efficiency: Streamline your body position and use strong, effective strokes to conserve oxygen.
Incorporate Core Training: Core strength improves your ability to hold a streamlined position during breath control drills.
Monitor Progress: Track your ability to hold your breath for longer intervals over time to measure improvement.
Don’t Skip Recovery: Give your body time to recover after intense hypoxic sessions to avoid overtraining.
Conclusion
Hypoxic training is a powerful tool for advanced freestyle swimmers looking to elevate their performance. By incorporating breath control drills into your routine, you can improve lung capacity, stroke efficiency, and mental toughness, all of which are essential for competitive swimming.
Remember to approach hypoxic training with caution, prioritize safety, and practice consistently to reap the benefits. Dive into the challenge, and watch your endurance and speed reach new heights!
