At the recent International Society for Equitation Science (ISES) Conference in Denmark, a Warwickshire College (UK) abstract covered research by distance-learning student Richard Mott from Ireland: He studied the potential difference in movement between shod and unshod horses in dressage.
To be fair to the researchers, this abstract is something like a snapshot from a moving car, compared to the author's much larger research effort. Richard Mott's thesis will actually be about 12,000 words when we finally get to read it.
