Swimming Kick Board: How to Use, Benefits, Drills, and Common Mistakes

How to Use a Swimming Kick Board?

A swimming kick board is a buoyant foam tool designed to isolate and strengthen the lower body, improve kick technique, and enhance aquatic fitness by providing upper body support during leg-focused drills.

What is a Kick Board?

A kick board, often simply called a "kickboard," is a fundamental piece of swim training equipment. Typically made from buoyant foam, it serves as a flotation device that swimmers hold to support their upper body and keep their head above water, thereby allowing them to focus exclusively on their leg movements. Its design varies, from traditional rectangular shapes to more hydrodynamic or ergonomic forms, but its core function remains consistent: to facilitate focused leg training.

Purpose and Design

The primary purpose of a kick board is to remove the upper body's contribution to propulsion, forcing the legs to work harder and more efficiently. This isolation helps swimmers develop leg strength, improve kick mechanics, and enhance cardiovascular endurance specific to swimming.

Benefits of Using a Kick Board

Integrating a kick board into your swim routine offers a multitude of physiological and technical advantages for swimmers of all levels.

• Enhanced Leg Strength and Endurance: By isolating the lower body, kick board drills significantly challenge the quadriceps, hamstrings, glutes, and calf muscles. This targeted training builds strength and muscular endurance, crucial for powerful and sustained propulsion in the water.
• Improved Kick Technique: Focusing solely on the kick allows swimmers to refine their technique without the complexities of coordinating arm movements. It helps in developing a symmetrical, consistent, and efficient kick, identifying and correcting common flaws like knee bending or scissoring.
• Core Stability and Body Position: While primarily for legs, effective kick board use demands strong core engagement to maintain a streamlined, stable body position. This indirectly strengthens the abdominal and lower back muscles, contributing to overall swimming efficiency.
• Rehabilitation and Low-Impact Training: For individuals recovering from upper body injuries or those seeking a low-impact cardiovascular workout, kick board training offers an excellent alternative. It allows for intense aquatic exercise without stressing the shoulders, arms, or back.
• Warm-up and Cool-down: Kick sets are excellent for warming up the major leg muscles before a main swim set or for a relaxed cool-down to flush lactic acid and maintain flexibility.

How to Properly Hold and Position the Kick Board

Correct form is paramount to maximize the benefits and prevent injury when using a kick board.

• Grip: Hold the kick board at the top edge with both hands, arms extended forward. Your hands should be flat on the board, fingers pointing forward, and thumbs wrapped underneath for a secure but relaxed grip. Avoid gripping too tightly, as this can create tension in the shoulders and neck.
• Arm Position: Your arms should be gently extended, almost straight but with a slight bend in the elbows. The board should be positioned directly in front of your head, just below the water's surface, allowing your head to rest comfortably between your arms, looking slightly forward.
• Body Alignment: Maintain a streamlined, horizontal body position. Your hips should be high in the water, aligned with your shoulders and head. Resist the urge to let your hips sink, as this creates drag and reduces efficiency. Engage your core to keep your body stable and flat.

Essential Kick Board Drills and Techniques

Varying your kick board drills targets different muscle groups and refines specific kicking styles.

• Basic Flutter Kick: This is the most common kick, used in freestyle and backstroke.
  • Technique: Keep legs relatively straight with a slight bend at the knees. The propulsion comes from the hips and glutes, with a continuous, rhythmic up-and-down motion. Feet should be relaxed, ankles plantar-flexed (pointed), and toes extended. Focus on a small, fast kick rather than a large, slow one.
  • Focus: Leg endurance, ankle flexibility, consistent propulsion.
• Dolphin Kick (Butterfly Kick): A powerful, undulating kick used in butterfly and underwater starts/turns.
  • Technique: Begin the movement from the chest/hips, creating a wave-like motion through the body. Both legs move together, simultaneously kicking downwards and then recovering upwards. Keep the core tight and generate power from the entire body, not just the knees.
  • Focus: Core strength, body undulation, powerful propulsion.
• Breaststroke Kick: Also known as the "frog kick" or "whip kick."
  • Technique: Start with knees bent and drawn up, heels close to the glutes. Rotate feet outwards (dorsiflexed and everted), then powerfully push water backwards and together in a circular motion, finishing with legs extended and feet pointed.
  • Focus: Inner thigh strength, ankle flexibility, coordinated propulsion.
• Vertical Kicking: Performed in the deep end of the pool, treading water vertically while kicking.
  • Technique: Can use flutter, dolphin, or breaststroke kick. Focus on maintaining your head above water using only your legs.
  • Focus: Intense leg strength, anaerobic endurance, water feel.
• Single-Arm Kick Board Drills: For advanced swimmers, this involves holding the board with one hand while the other arm extends forward or performs a sculling motion.
  • Technique: Challenges core stability and balance more significantly.
  • Focus: Core strength, balance, body rotation.

Common Mistakes to Avoid

Even a simple tool like a kick board can be used inefficiently if common errors are not addressed.

• Over-reliance on the Board: Using the board to pull yourself through the water instead of letting your legs do the work. The board is for support, not propulsion.
• Poor Body Position: Allowing hips to sink, creating excessive drag. This often stems from a weak core or trying to lift the head too high.
• Holding Too Tightly: A death grip on the board creates tension in the shoulders and neck, leading to fatigue and poor body alignment. Relax your grip.
• Ignoring Arm Position: Letting arms bend excessively or allowing the board to tilt too much, which disrupts balance and streamlines.
• Only Kicking from the Knees: This is a common flaw, especially in flutter kick. Power should originate from the hips and glutes, with the entire leg (and foot) acting as an extension. Kicking only from the knees is inefficient and can strain joints.

Incorporating the Kick Board into Your Workout

A kick board can be integrated into various phases of your swim workout.

• Warm-up Sets: Use short, easy kick sets (e.g., 4 x 50m easy flutter kick) to activate leg muscles and get a feel for the water.
• Main Set Focus: Dedicate specific sets to kick training, varying distances, intensity, and kick types (e.g., 6 x 100m moderate flutter kick with 20s rest, or 8 x 25m fast dolphin kick).
• Cool-down: Finish your workout with a relaxed, long-distance kick set to help flush lactic acid and promote recovery.
• Interval Training: Incorporate kick sets into high-intensity interval training (HIIT) to improve anaerobic capacity and speed.

Selecting the Right Kick Board

While most kick boards are similar, subtle differences can impact your experience.

• Material and Buoyancy: Most are made of EVA foam. Ensure it provides adequate buoyancy for your body weight without being overly stiff or cumbersome.
• Size and Shape: Traditional rectangular boards offer stable support. Ergonomic designs with hand cut-outs or contoured edges can offer more comfort and versatility for different drills. Smaller boards offer less support but demand more core engagement.
• Ergonomics: Some boards have a slight curve or indentations for better hand placement, promoting a more natural grip and reducing forearm strain.

Conclusion

The swimming kick board is an indispensable tool for swimmers looking to enhance their lower body strength, refine their kick technique, and improve overall aquatic fitness. By understanding its purpose, mastering proper holding techniques, and incorporating diverse drills into your routine, you can unlock a new level of efficiency and power in the water. Remember to prioritize technique over speed, listen to your body, and consistently integrate kick sets for measurable improvements in your swimming performance.
