Background Research concerning footing and its contribution to injuries has been conducted primarily in racing Thoroughbreds. Studies in UK and Japan indicate that some specific factors could be responsible for an increase in performance-associated injuries. Researchers in Sweden have performed studies on Standardbred trotters. More research is needed to be done on equestrian sports since requirements on footing are not exactly the same in riding and trotting horses. The lack of scientific evidence on the construction of equestrian surfaces has lead to anecdotal validation of designs. The market place has boundless numbers of commercial surfaces available and each claiming to be appropriate for the athletic horse. Recently, though accelerometers have been applied to measuring surface design and interaction between the horse and surface. In this study, accelerometers are used in a very simple and non-invasive manner. It is a pilot and is a small part of a larger international research project. Purpose To evaluate the use of a simple accelerometer-based measuring technique to assess ground properties under field conditions. Material and Methods Five professional Swedish riders (show jumping) were chosen and the trials were made at their main training camps. Two horses at each training facility were equipped with accelerometers, attached to a custom made protection boot, to all four limbs. The horses were ridden over the different riding surfaces at the camp and data was collected through a wireless system to a portable computer. Each horse was also ridden on a surface with high surface firmness, asphalt or gravel (or both if available). This data was used as reference surfaces since asphalt/gravel are surfaces that could be assumed to have similar characteristics when measuring surface hardness. All surfaces were described regarding build-up. Raw data from the trials was processed in MatLab© and Microsoft Excel© to get presentable data. Summarized acceleration and frequency domain data on the amount of measured high frequency vibrations was performed since there are indications in previous studies that this is causing skeletal injuries in the horse. Data from each surface was compared to the reference surface (gravel/asphalt). The use of a reference surface helps to account for the differences in data caused by the inter variability in the moving pattern of the horses. Results and discussion Results obtained in this minor study show that it is possible to correlate the relationship between data collected from an accelerometer attached to a protection boot and the assumed surface hardness of a riding surface. Measurements from horses within the same camp showed similar results, when compared to a reference surface (i.e. asphalt/gravel). Concerning study design, the most important conclusion is that speed has to be controlled to minimize a major source of error.
