The Great Divide: Why ONCORE and Traditional Kickboards Are Worlds Apart

 When it comes to swimming training aids, not all foam tools are created equal. While both ONCORE and traditional kickboards share foam construction, their design philosophies, intended uses, and training outcomes are fundamentally different. Understanding these distinctions is crucial for swimmers, coaches, and aquatic professionals who want to maximise their training effectiveness.

The Traditional Kickboard: Built for Buoyancy and Isolation

Traditional kickboards have been a pool deck staple for decades, designed for maximum buoyancy while isolating leg movements. These boards typically feature a large surface area measuring 46-61 centimeters in length and 30-41 centimeters in width, with thickness ranging from 3-4 centimeters, constructed from high-density closed-cell foam. This generous size creates significant buoyant force, acting as a floating platform that keeps the swimmer's upper body elevated and stable at the water's surface.

Research consistently shows kickboard effectiveness for leg strength development, cardiovascular conditioning, technique refinement without upper body interference, and rehabilitation support. The design philosophy centers on support and isolation, keeping swimmers afloat while focusing exclusively on their kick.

ONCORE: Engineered for Engagement and Integration

ONCORE represents a completely different approach, with design features that challenge rather than support the swimmer. Its compact surface area has a significantly smaller footprint than traditional kickboards, with precise thickness specifications and low-density foam construction chosen to provide textured, controllable resistance rather than maximum buoyancy.

The fundamental difference lies in submersion capability. While kickboards stay on the surface, ONCORE is designed to be submerged during use. This is made possible by controlled buoyant force that provides resistance without overwhelming the swimmer, a textured surface that enhances grip and neurological feedback when submerged, and optimal density for controlled submersion while maintaining structural integrity.

Training Philosophy: Support vs. Challenge

Traditional kickboards operate on a support model: eliminating upper body variables, providing stability and confidence, allowing focus on isolated movements, and reducing core engagement requirements. ONCORE employs a challenge model that demands full-body integration, requires active core stabilisation, promotes proprioceptive awareness, and develops functional strength patterns.

Why They're Not Interchangeable

When to Use a Kickboard:

·       Building pure leg strength

·       Isolating kick technique

·       Cardiovascular conditioning focused on lower body

·       Supporting swimmers who need upper body rest (e.g. injury rehab)

When to Use ONCORE:

·       Developing core stability and body alignment

·       Improving stroke technique and water feel

·       Building functional strength patterns

·       Enhancing proprioceptive awareness

The Integration Advantage

Kickboards create an artificial training environment where the upper body is supported in a way that never occurs in actual swimming. While valuable for specific goals, this doesn't translate directly to integrated swimming performance.

ONCORE creates a technique-enhancing environment where every design aspect works to improve actual swimming mechanics and body awareness through controlled submersion and resistance.

Conclusion: Choosing the Right Tool for the Right Job

The swimming world has room for both tools, but understanding their fundamental differences is crucial for effective training. Traditional kickboards excel at isolated leg training support. ONCORE excels at challenging swimmers to develop better technique, core engagement, and body awareness.

These tools are not interchangeable – they're complementary. Just as a carpenter wouldn't use a hammer when a screwdriver is needed, swimmers and coaches must choose the right tool for their specific training objectives. While both share foam construction, their worlds of application are indeed far apart – and that's exactly how it should be.
