Comparing Two Flutter Kicks vs Four Flutter Kicks for Open Water Swimming

Open water swimming challenges athletes with unpredictable conditions and long distances. Choosing the right flutter kick technique can make a significant difference in efficiency, speed, and endurance. Two common flutter kick patterns are the two flutter kick and the four flutter kick. Understanding what each involves, their differences, and how to train for them can help swimmers optimize their performance in open water.

What Are Two Flutter Kicks and Four Flutter Kicks?

Flutter kicks are a fundamental part of freestyle swimming, involving alternating up-and-down movements of the legs. The difference between two flutter kicks and four flutter kicks lies in the number of kicks performed per arm cycle.

• Two Flutter Kicks: This technique involves two kicks for every full arm stroke cycle (one kick per arm pull). It is a more relaxed and energy-efficient pattern.

  
  

• Four Flutter Kicks: This involves four kicks per arm cycle (two kicks per arm pull). It increases propulsion and helps maintain body position but requires more energy.

  
  

Both techniques aim to provide propulsion and stability but differ in intensity and application.

Key Differences Between Two Flutter Kicks and Four Flutter Kicks

| Aspect | Two Flutter Kicks | Four Flutter Kicks |

|----------------------|------------------------------------------|------------------------------------------|

| Kick Frequency | Two kicks per arm cycle | Four kicks per arm cycle |

| Energy Use | Lower energy consumption | Higher energy consumption |

| Propulsion | Moderate propulsion | Increased propulsion |

| Body Position | Good for maintaining streamlined position| Better for stabilizing in rough water |

| Fatigue Factor | Less tiring over long distances | More tiring, especially in long swims |

| Use Case | Long-distance, endurance-focused swims | Sprinting, rough water, or technical needs|

How to Use Each Flutter Kick Technique

Using Two Flutter Kicks

Two flutter kicks work well for long-distance open water swimming where conserving energy is crucial. This technique allows swimmers to maintain a steady pace without exhausting their legs too quickly.

• When to use: During steady-state swimming, long races, or when conditions are calm.

• How to execute: Coordinate one kick with each arm pull, focusing on smooth, controlled movements. Keep the kicks compact to reduce drag.

• Benefits: Saves energy, reduces muscle fatigue, and maintains a streamlined body position.

  
  

Using Four Flutter Kicks

Four flutter kicks provide more propulsion and help stabilize the body, especially in choppy or turbulent water. This technique can be useful during sprints or when extra power is needed.

• When to use: In rough water, during bursts of speed, or when navigating waves and currents.

• How to execute: Perform two quick kicks per arm pull, emphasizing a strong, continuous flutter. Keep the legs active but avoid excessive splashing.

• Benefits: Improves propulsion, enhances balance, and helps maintain forward momentum in challenging conditions.

  
  

Benefits of Two Flutter Kicks and Four Flutter Kicks

Benefits of Two Flutter Kicks

• Energy Efficiency: Uses less oxygen and muscle power, allowing swimmers to sustain effort over long distances.

• Reduced Fatigue: Less leg movement means lower risk of cramping and exhaustion.

• Streamlined Position: Helps maintain a flat, hydrodynamic body position, minimizing drag.

• Better Breathing Rhythm: Easier to coordinate breathing with arm strokes and kicks.

  
  

Benefits of Four Flutter Kicks

• Increased Propulsion: More kicks generate additional forward thrust.

• Improved Stability: Helps keep the body balanced in waves or currents.

• Enhanced Speed: Useful for sprinting or accelerating during races.

• Better Control: Allows swimmers to adjust body position quickly in response to water conditions.

  
  

What to Use in Long Distance Open Water Swimming

For long-distance open water swimming, the two flutter kick is generally the preferred choice. The main reason is its energy efficiency. Long swims require conserving strength and oxygen, and two kicks per arm cycle help achieve this balance.

That said, swimmers often switch to four flutter kicks in specific situations, such as:

• Navigating rough patches of water

• Sprinting toward a buoy or finish line

• Adjusting body position to sight or avoid obstacles

  
  

Using a hybrid approach—primarily two flutter kicks with occasional bursts of four flutter kicks—can provide the best balance between endurance and power.

How to Train for Two Flutter Kicks and Four Flutter Kicks

Training for Two Flutter Kicks

• Focus on Endurance: Swim long sets with a two-kick pattern to build stamina.

• Drills: Use kickboards or streamline drills emphasizing controlled, compact kicks.

• Breathing Coordination: Practice breathing patterns that sync with two kicks per stroke.

• Leg Strength: Incorporate dryland exercises like squats and lunges to build leg endurance without overexertion.

  
  

Training for Four Flutter Kicks

• Interval Training: Include short, high-intensity sets with four kicks per arm cycle to build power.

• Kick Drills: Use fins to increase kick speed and strength, focusing on quick, continuous fluttering.

• Core Stability: Strengthen core muscles to maintain body position during rapid kicking.

• Flexibility: Stretch ankles and calves to improve kick range and reduce injury risk.

  
  

Practical Tips for Open Water Swimmers

• Experiment in Training: Try both kick patterns in different conditions to find what works best for you.

• Listen to Your Body: Use two kicks when conserving energy and switch to four kicks when you need extra propulsion.

• Combine with Arm Technique: Efficient arm strokes complement your kick pattern and improve overall speed.

• Use Equipment Wisely: Fins can help train kick strength but avoid over-reliance.

  
  

Choosing between two flutter kicks and four flutter kicks depends on your swimming goals, distance, and water conditions. Two flutter kicks offer energy savings and endurance, making them ideal for long-distance open water swims. Four flutter kicks provide extra power and stability, useful in rough water or sprinting.
