Arena surface vertical impact forces vary with surface compaction.
- Journal Article
Summary
The research under study investigates how different levels of surface compaction in equine arenas can alter the vertical impact force experienced by horses. By comparing both dirt and synthetic surfaces, and examining them both when harrowed and compacted, results ultimately suggested that less compact (harrowed) surfaces can help lower the risk of musculoskeletal injuries in horses, with these benefits being more notable on dirt surfaces.
Research Goals and Methodology
The experiment was designed to measure and compare the vertical impact forces on different types of arena surfaces, namely dirt and synthetic. This was done in an effort to understand and manage the risk of musculoskeletal injuries in horses, which can be influenced by the mechanical properties of the surfaces they move on. The tests were performed at five different locations on a total of 12 arenas, five of which had dirt surfaces and seven synthetic.
- Eight impact-related variables were calculated considering factors like impact force, displacement and acceleration.
- Additional observations were made regarding the surface temperature, cushion depth, and moisture content of the arena.
- Both types of surfaces were tested under harrowed and compacted conditions.
- An analysis of variance was employed to assess the effects of surface material and cushion compaction on the vertical impact properties.
- The relationships between surface properties that can be managed and vertical impact forces were examined through correlations.
Findings
The results showed a notable difference in vertical impact force between harrowed and compacted cushions. Compacted cushions exhibited higher vertical impact force and deceleration, with reduced vertical displacement compared to their harrowed counterparts. The effect was found to be stronger on dirt surfaces compared to synthetic ones.
- Surface type affected only two of the several considered variables: vertical displacement and soil rebound.
- Any changes in the surface compaction had a more significant effect on the resulting vertical impact forces as compared to changes made to the type of surface (dirt or synthetic).
Conclusion
The research concludes that by reducing surface compaction via harrowing, one can minimize the risk of musculoskeletal injury in horses. Of the surfaces examined, these benefits were more pronounced on dirt surfaces compared to their synthetic counterparts. Consequently, the study recommends regular harrowing of surfaces, especially those composed of dirt, to reduce the potential for injury in equines.
