Kickboard Buying Guide: Standard vs. Streamlined Kickboards Compared for Training Effectiveness

Introduction

Almost everyone who has learned to swim has held a kickboard at some point. As the most basic swim training tool, a kickboard isolates the upper body so swimmers can focus on leg-kick training. However, research shows that using a traditional flat kickboard often causes the swimmer’s lower back to arch excessively, putting the body in a position quite different from actual swimming posture. This is a major reason why streamlined (hydrodynamic) kickboards have gained popularity in recent years.

Core Differences: Standard vs. Streamlined Kickboards

Design Philosophy

Standard kickboard: A flat, rectangular design aimed primarily at maximizing buoyancy. The swimmer presses down on the board with both hands, keeping the forearms floating horizontally on the surface.

Streamlined kickboard: Tapered at the front and slightly wider at the back, or shaped with grooves for the swimmer’s hands, allowing the arm angle to sit closer to the extended position used in freestyle swimming.

Impact on Body Position

Pros and Cons of the Standard Kickboard

Pros

• Cheap and durable: Usually made of EVA foam, nearly indestructible, and available for around NT$150–400
• High buoyancy: Easier for beginners or swimmers with weaker shoulder strength to stay afloat
• Versatile: Can also be used for pull-buoy-style leg squeezes or as resistance for pulling drills
• Convenient for teaching: Widely used in swim classes, easy to clean and disinfect

Cons

• Lower-back posture issue: Pressing down with both hands raises the shoulders above the hips, causing an unnatural arch in the lower back; prolonged use can lead to lower-back discomfort
• Doesn’t match the swimming kinetic chain: The body position during kicking differs significantly from actual swimming, so the neuromuscular pattern transfers poorly
• Slower swimming speed: The larger frontal area creates extra drag, making it unsuitable for speed training

Pros and Cons of the Streamlined Kickboard

Pros

• Matches swimming posture: Grip angles found on boards like the Speedo Elite Kickboard or Finis Alignment Board bring the body’s extended line closer to the horizontal line used in freestyle or butterfly
• Improves core activation: A more horizontal body position requires greater abdominal and core tension, training core stability at the same time
• Shoulder-friendly: Some models feature cutouts that let the swimmer hold the board with a more natural shoulder-joint angle
• Improved kicking efficiency: Research shows kicking speed with a streamlined kickboard is on average about 5–8% faster than with a standard kickboard

Cons

• Higher price: NT$500–1,500, more expensive than the standard version
• Learning curve for beginners: Swimmers unfamiliar with the design may feel unstable at first
• Lower buoyancy than a standard board: Legs sink more noticeably, requiring stronger core control

Specialty Kickboards

• Finis Alignment Board: Features a groove for the head to rest against, forcing correct head position — well suited to backstroke kick training
• Mini kickboard: A compact size often used for specialized butterfly or backstroke kick drills
• Transparent reinforced board: Lets swimmers see their own body position, mainly used for teaching demonstrations

Best Kick-Training Combinations

• Beginners: Standard kickboard + goggles, focused on learning the six-beat kick rhythm
• Intermediate swimmers: Streamlined kickboard, with attention to core engagement to improve body line
• Advanced competitive swimmers: Alternate between a streamlined kickboard and short fins to improve ankle flexibility

Practical Buying Tips

1. Assess your own lower-back condition: If you have lower-back pain, a streamlined kickboard is strongly recommended, or check proper usage posture with a coach
2. Try different grip designs: Grip size suitability affects usability, especially for swimmers with larger or smaller hands
3. Buoyancy test: Push the board underwater and release it — the faster it pops back up, the better the buoyancy; cheap boards with uneven EVA density often show inconsistent buoyancy
4. Recommended Taiwan swim shops: Chains such as Orange Swimming and Dolphin Swim Gear carry a range of models you can try in person

Conclusion

If your goal is to improve overall swimming performance rather than simply train your legs in isolation, investing in a streamlined kickboard is worthwhile. It keeps the body in a more correct horizontal position, allowing the gains from leg training to transfer more efficiently to full-stroke swimming. The standard kickboard remains a solid choice for teaching, beginners, and multi-purpose training support, and it certainly isn’t obsolete — but if you already have a solid foundation, upgrading to a streamlined kickboard can significantly boost the benefit of every kick session.
