1. Buoyancy: Kicking boards are designed to provide buoyancy, allowing swimmers to stay afloat and focus on lower body movements. The primary materials used for achieving buoyancy are:
- EVA Foam: Ethylene-vinyl acetate (EVA) foam is a popular material for kicking boards because of its lightweight and excellent buoyancy properties. EVA foam boards are soft, flexible, and provide sufficient support for swimmers to rest their arms.
- Polyethylene: Polyethylene, another commonly used material, offers high buoyancy and durability. Polyethylene boards are often lightweight and come in various thicknesses, catering to different skill levels and preferences.
2. Density: The density of a kicking board relates to how much force it takes to push or move it through the water. High-density kicking boards require more effort to move, providing resistance and enhancing leg strength training. Low-density boards are easier to move, making them suitable for beginners and those focusing on technique.
3. Shape and Size: The shape and size of a kicking board can impact its functionality. Common shapes include rectangular, contoured, and tapered designs, each catering to different swimming styles and body positions. The size of the board also varies, with larger boards providing more surface area for support and stability.
4. Rigidity: The rigidity or flexibility of a kicking board affects its responsiveness to leg movements. Some boards are designed to be flexible to allow for a more natural kicking motion, while others are more rigid, providing a stable platform for swimmers to push against. The choice of rigidity depends on individual preferences and training objectives.
5. Durability: The durability of a kicking board is essential for long-lasting performance. Materials like EVA foam and polyethylene are known for their resilience, resisting cracking, tearing, and water absorption, ensuring the board's longevity in the pool environment.
By considering these physical properties, swimmers can select a kicking board that suits their swimming level, training goals, and personal preferences, enhancing their swimming training and overall performance in the pool.
