On this excerpt, tailored from Your Full Information to Equine Arenas, equestrian journalist and horsewoman Abigail Boatwright explains among the key elements in making certain our horses’ well being, from the bottom up.
Grass surfaces have traditionally been used for horse coaching and competitors arenas. Nevertheless, with local weather points, year-round use, required upkeep, demanding efficiency maneuvers, and heightened damage dangers, there’s been a rise within the use and availability of artificial surfaces. Grass is now much less frequent for efficiency {and professional} arenas.
In absence of grass, most arenas are actually comprised of mixtures of sand, silt, clay, and components, corresponding to woodchips, rubber, or fibers. Despite the fact that we’re working with only a few substances, many elements can change how a footing materials feels and behaves.
Consistency is essential to a very good enviornment floor. Whereas a horse can adapt to a spread of surfaces, coaching on dramatically completely different surfaces could negatively affect efficiency and may be related to damage.
There’s a conundrum, although. In contrast to surfaces designed for human athletics, an enviornment footing perfect for equine efficiency will not be all the time perfect for long-term soundness, in accordance with research cited in “Equine Surfaces White Paper” (printed by the FEI). Footing for any equine sport ought to reduce concussion—of the hoof—by power absorption, however nonetheless rebound energy to help efficiency. Listed here are a couple of phrases used within the “Equine Surfaces White Paper” and all through the horse world that should be understood with the intention to select and preserve enviornment footing together with your horse’s well being in thoughts:
Shock Absorption—That is both frictional and comes from particles being displaced, or structural, the place shock absorption is achieved by compacting particles that may regain their form. A floor’s firmness in opposition to affect, and the quantity of cushioning it has, determines how a lot a floor can soak up shock.
Shear Power—When a hoof lands on a floor, the shear energy is the quantity of resistance the footing can supply to maintain the hoof from transferring horizontally. This must be optimized for particular occasions—for instance, barrel racing requires increased shear energy to keep away from potential slipping. Shear energy relies on moisture content material, temperature, and the composition of the world materials.
Hardness—That is how a lot resistance a cloth has in opposition to penetration with an outlined object and an outlined quantity of stress. It’s troublesome to measure hardness precisely on enviornment surfaces. It’s associated to stiffness—the ratio of utilized power to deflection.
Response Time—The time between deformation of the floor when weight is added—a hoof touchdown—and the following elastic restoration—a hoof leaving. If the elastic restoration happens too rapidly, elevated power shall be taken on by the horse’s limbs.
Lack of Vitality—When a hoof impacts a floor, among the power from the collision is misplaced. The quantity relies on the elasticity of the floor’s high layer.
Consistency—The Oxford English Dictionary defines consistency as “conforming to an unchanging sample.” When referring to arenas, we’re speaking concerning the consistency of the fabric round all areas of the world, and from one time limit to a different. Moisture content material is the most important variable in footing’s consistency. However inconsistent depth contributes probably the most to the chance of lameness, in accordance with a examine on dressage horses.
Affect Firmness—That is the shock skilled by the horse and rider when the hoof contacts the floor. This pertains to the hardness of the very high surfaces and its preliminary stiffness when your horse’s hoof lands on it. Concrete has a really excessive affect firmness. While you put a skinny layer of sand on high of concrete, you have got far much less affect firmness, whereas nonetheless having good help. While you place wooden over moist clay, you have got good affect firmness, whereas nonetheless having some cushion because the horse steps.
Cushioning—The supportiveness of a floor to the horse in comparison with how a lot “give” it has. You may also consider this as power discount—how the layers of the footing soak up affect—when a hoof lands. A floor missing good cushioning is stiff, or laborious. One instance of footing with good cushioning, however little elasticity, is a sandy seaside with dry, deep sand.

Responsiveness—That is how “springy” the floor feels to the rider and the horse. Consider a trampoline. While you push downward due to your weight, it springs again and even bounces you upward. If the timing of the rebound matches the horse’s motion, it can really feel springy. If not, it can really feel “lifeless” with no springiness to it. For instance, a floor that’s closely compacted may rebound too rapidly, which makes it really feel stiff or “lifeless.”
Grip—The quantity of sliding—horizontal motion—the horse’s hoof does throughout touchdown, turning and pushing off. This comes from the interplay between the horse’s hoof and the supplies that interlock and maintain the floor collectively. Friction on the highest layer impacts how your horse’s hoof lands. You need a little bit little bit of slide to assist soak up the affect, however not a lot that the floor is “slippery.” Your horse wants to have the ability to push off the layer just under the floor. A excessive grip floor will cease your horse too rapidly, whereas too little grip will permit him to slip an excessive amount of.
Uniformity—How constant the floor feels because the horse strikes throughout it. An enviornment can look stage, however the affect firmness, cushioning, responsiveness, and grip can nonetheless range. Your horse can deal with gradual adjustments throughout an enviornment, particularly in the event that they’re seen. However sudden or wildly variant adjustments could cause your horse to journey or change into injured.
Consistency Over Time—This refers to how a lot the floor adjustments with time and use. Sand can break down into smaller and smaller items, which flip into silt. Moisture adjustments can have an effect on the grip, cushioning, and different elements as the world dries out throughout a day. Horses engaged on the footing can alter consistency alongside the observe and in different excessive site visitors areas.
Floor Composition—Composition varies by area and self-discipline. For instance, riders in the UK typically use surfaces which are comprised of sand and rubber, sand and woodchip, and sand and polyvinylchloride (PVC). Widespread components for dressage or leaping arenas embody artificial or pure fibers, rubber, and material or felt strips. A polymer or wax coating can be utilized to sand. This binds the footing materials collectively and creates a hydrophobic—water-repellant—coating.
Footing Takeaway: To create the very best footing, you not solely want the suitable supplies within the appropriate mixture, however the moisture stage have to be adjusted regularly and the world floor wants correct dragging to advertise a constant free depth on high of your enviornment base. You can not have good footing, with even the very best supplies, with out care and water.
