[Video] The Influence of Diagonal Dissociation and Changes in Speed on Trotting Horses
Although the trot is described as a diagonal gait, contacts of the diagonal pairs of hooves are not usually perfectly synchronized. Although subtle, the timing dissociation between contacts of each diagonal pair could have consequences on gait dynamics and provide insight into the functional strategies employed.
Dr. Sarah Jane Hobbs, a researcher in equine biomechanics at the University of Central Lancashire, will explore the mechanical effects of different diagonal dissociation patterns when speed was matched between individuals and how these effects link to moderate, natural changes in trotting speed.
She’ll show that hind-first diagonal dissociation at contact increases with speed, diagonal dissociation at contact can reduce collision-based energy losses and predominant dissociation patterns will be evident within individuals.
