Rubber crumb and recycled rubber surfaces in equine arenas offer improved cushioning and reduced concussive loading compared to plain sand, with welfare benefits for joint health.
Arena surface composition is a direct welfare determinant affecting joint loading in every stride. Rubber crumb addition to standard sand surfaces reduces peak impact forces and improves energy return compared to hard sand, reducing the cumulative loading that contributes to joint degeneration. Horses worked long-term on appropriate rubber-sand surfaces show lower rates of lameness in some studies compared to those worked on hard plain sand. The welfare investment in appropriate surface composition is sustained across the lifetime of the surface, protecting all horses who use it from excessive concussive joint loading.
