Received: 9 August 2019; Accepted: 13 August 2019; Published: 20 August 2019 Abstract: The Estonian Native Horse (ENH) is a medium-size pony found mainly in the western islands of Estonia and is well-adapted to the harsh northern climate and poor pastures. The ancestry of the ENH is debated, including alleged claims about direct descendance from the extinct Tarpan. Here we conducted a detailed analysis of the genetic makeup and relationships of the ENH based on the genotypes of 15 autosomal short tandem repeats (STRs), 18 Y chromosomal single nucleotide polymorphisms (SNPs), mitochondrial D-loop sequence and lateral gait allele in DMRT3. -
Pyramid of Training – Rhythm
Chapter 9 PYRAMID OF TRaining – RHYTHM Energy and Tempo Rhythm is the term used for the characteristic sequence of footfalls and timing of a pure walk, pure trot, and pure canter. The rhythm should be expressed with energy and in a suitable and consistent tempo, with the horse remaining in the bal- ance and self-carriage appropriate to its individual conformation and level of training. “The object of correct dressage is not to teach the horse to perform the exercises of the High School in the collected gaits at the expense of the elementary gaits. The classical school, on the contrary, demands that as well as teaching the difficult exercises, the natural gaits of the horse should not only be preserved but should also be improved by the fact that the horse has been strengthened by gymnastics. Therefore, if during the course of training the natural paces are not improved, it would be proof that the training was incorrect.” [The Complete Training of Horse and Rider, p 161] One important function of basic training is to preserve and refine the purity and regularity of the natural gaits. It is there- fore essential that the trainer knows exactly how the horse moves in each of the three basic gaits, because only then will he be in a position to take the appropriate action to correct or improve them. When establishing rhythm, “the horse should be ridden in the basic pace best suited to it.” [Principles of Riding, p. 160] The rhythm must be maintained in each of the basic gaits, and in each form of the gait, i.e. -

List of horse breeds 1 List of horse breeds This page is a list of horse and pony breeds, and also includes terms used to describe types of horse that are not breeds but are commonly mistaken for breeds. While there is no scientifically accepted definition of the term "breed,"[1] a breed is defined generally as having distinct true-breeding characteristics over a number of generations; its members may be called "purebred". In most cases, bloodlines of horse breeds are recorded with a breed registry. However, in horses, the concept is somewhat flexible, as open stud books are created for developing horse breeds that are not yet fully true-breeding. Registries also are considered the authority as to whether a given breed is listed as Light or saddle horse breeds a "horse" or a "pony". There are also a number of "color breed", sport horse, and gaited horse registries for horses with various phenotypes or other traits, which admit any animal fitting a given set of physical characteristics, even if there is little or no evidence of the trait being a true-breeding characteristic. Other recording entities or specialty organizations may recognize horses from multiple breeds, thus, for the purposes of this article, such animals are classified as a "type" rather than a "breed". The breeds and types listed here are those that already have a Wikipedia article. For a more extensive list, see the List of all horse breeds in DAD-IS.

Hunter Seat Equitation Manual
Hunter Seat Equitation Manual Copyright March 2002 Do not reproduce without permission of : USA Equestrian 4047 Iron Works Parkway Lexington, KY 40511 www.equestrian.org Hunter Seat Equitation Manual – 2002 1 PREFACE The purpose of this manual is to create a comprehensive set of standards for everyone who judges Hunter Seat Equitation. There is a clear need for a tool such as this. Due to the continuing and rapid growth of our sport we need to have clear guidelines for judges in order to maintain uniformity and a high level of quality in the show ring. Our system of equitation, “Hunter Seat Equitation” is the envy of the world. This manual is being presented by the Continuing Education committee of USA Equestrian, our national governing body. It will be reviewed and updated annually by the USA Equestrian Hunter Seat Equitation Committee and will be part of the curriculum that all judges must address before they are granted our national judges card through the Federation’s Licensed Officials Committee. It is hoped that by adding this uniformity and stability in the show ring that we will not only raise the standard of riding, training, and judging, but we will also be able to better preserve this high level for future generations. This Manual is a joint contribution from the following organizations: WCE, West Coast Equestrians, a non-profit organization dedicated to promoting our sport on the west coast, PCHA, Pacific Coast Horse Shows Association, from members of the PCHA Hunter Seat Equitation Committee, USA Equestrian Hunter Seat Equitation Committee.

Clayton 1,2,* and Sarah Jane Hobbs 3 1 Sport Horse Science, 3145 Sandhill Road, Mason, MI 48854, USA 2 College of Veterinary Medicine, Michigan State University, East Lansing, MI 48824, USA 3 Centre for Applied Sport and Exercise Sciences, University of Central Lancashire, Preston PR1 2HE, UK; [email protected] * Correspondence: [email protected]; Tel.: +1-517-333-3833 Received: 17 September 2019; Accepted: 2 October 2019; Published: 3 October 2019 Simple Summary: This paper reviews the biomechanical classification of diagonally coordinated gaits of dressage horses, specifically, collected trot, passage and piaffe. Each gait was classified as a walking gait or a running gait based on three criteria: limb kinematics, ground reaction forces and center of mass mechanics. The data for trot and passage were quite similar and both were classified as running gaits according to all three criteria. In piaffe, the limbs have relatively long stance durations and there are no aerial phases, so kinematically it was classified as a walking gait. However, the shape of the vertical ground reaction force curve and the strategies used to control movements of the center of mass were more similar to those of a running gait. The hind limbs act as springs with limb compression increasing progressively from collected trot to passage to piaffe, whereas the forelimbs show less compression in passage and piaffe and behave more like struts. Abstract: Gaits are typically classified as walking or running based on kinematics, the shape of the vertical ground reaction force (GRF) curve, and the use of inverted pendulum or spring-mass mechanics during the stance phase. -

Change of Canter Lead Through Trot on the Diagonal
Chapter 19 CHANGES OF LEAD AND FLYING CHANGE OF LEAD Definition Change of Lead Through Trot “This is a change of lead where the horse is brought back to the trot and after a few trot strides, is restarted into a canter with the other leg leading.” [USEF Rule Book DR105] Simple Change of Lead “This is a change of lead where the horse is brought back immediately into walk and, after a few steps, is restarted im- mediately into a canter on the opposite lead, with no steps at the trot.” [USEF Rule Book DR105] Gymnastic Purpose The gymnastic purposes of changes of lead are to help develop, as well as test, the horse’s collection, coordination and balance, and to improve the quality of the canter. Qualities Desired The qualities desired in ‘Changes of Lead through Trot,’ are that the horse maintains his straightness, makes a balanced transition to two to three steps of trot, and strikes off clearly to the new canter lead. The qualities desired in a ‘Simple Change of lead’ are basically the same as the change through the trot except that the transition from canter should go directly to two to three walk steps, and to the new canter lead with no trot steps. The transition to walk must be immediate without any intervening vaguely trot-like strides, but also smooth. The steps must be determined and the four footfalls of the gait must be distinct. The transition to the new canter must also be im- mediate. The horse must canter straight and must constantly remain on the bit.” [Dressage, A Guidebook for the Road to Success, p 103] Aids The aids for changes of lead are the same as the aids for the canter. -
Convert That Trot by Lee Ziegler
trot Page 1 of 5 Convert That Trot by Lee Ziegler It doesn’t happen very often, but sometimes a gaited horse isn’t as ‘gaited’ as he should be. Some of them just seem to prefer to hard trot most or even all of the time. These horses are not as difficult to deal with as their pacing cousins, but they can be frustrating, especially for riders who have bought gaited horses in the hopes of never having to deal with a hard trot again. Horses trot for the same reasons they do any other gait – their conformation, body position, muscle use and neurological “wiring” incline them to do the gait. For a gaited bred horse that trots, in addition to these factors, there may also be a lack of rhythm that causes the horse to miss out on the special harmony that should produce his easy gait. Conformation that inclines to a trot: Horses with functional backs that are shorter than the average for their breed will often trot. Horses with relatively short lumbar spans (the vertebrae between the last rib and the lumbo-sacral junction) will also be more inclined to trot. Low headed horses that stretch easily forward will also be more inclined to trot than higher headed types. Horses with hind and front legs that are about the same length, elbow to ground and stifle to ground, may be inclined to trot. Body/muscle use that inclines to a trot: Horses with slightly rounded backs, and stretched toplines will be inclined to trot. Horses that easily tip their pelvises downward and flex downward from the lumbo-sacral junction will be inclined to trot. -

Gaited horses have been around for many years, but how did they end up in the American Saddlebred? This series of articles will take you from the dawn of the gaited horse through to the modern day Saddlebred, look at the genetics behind the ambling gait and give you some pointers as to the physique of the gaited horse. What is a gaited horse anyway? Every pace of the horse, be it walk, trot or canter, is called a “gait”. For the gaited enthusiast, any horse can do these gaits, what they are interested in is the smooth non-jarring English palfrey, cc 1795 – 1865. lateral gait (the legs on one side moving together). (http://www.1st-art-gallery.com/John- This “gait” comes in many guises and names Frederick-Herring-Snr/My-Ladye's-Palfrey.html). depending on the collection, speed and length of stride of the horse, as well as the individual breed of the horse. It is the specific pattern of footfall and the cadence that defines the gait in each of the gaited breeds. A quiet horse may well have a better gait than his flashy fast-moving counterpart, so look beyond the hype and see exactly what those feet and hindquarters are doing. This smooth-moving gait has been depicted in cave walls and fossilised in footprints dating to over 3½ million years ago – so just how did it get from there Lady Conaway's Spanish Jennet to the American Saddlebred? We know that horses (http://www.spanishjennet.org/registry.shtml) are not native to America, so to answer that question we must travel back in time and place to Europe and Asia.
