Equitation Science is the study of the interactions between horses and humans, focusing on the application of scientific principles to improve horse training, management, and welfare. This interdisciplinary field incorporates knowledge from areas such as ethology, biomechanics, and learning theory to better understand equine behavior and the effects of human practices on horses. Research in equitation science aims to develop evidence-based methods for training and handling that promote welfare and performance. Topics of study include the assessment of training techniques, the impact of equipment on horse physiology, and the evaluation of stress and learning in equine subjects. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, findings, and implications of equitation science in the context of horse-human interactions.
Clayton HM, Hampson A, Fraser P, White A, Egenvall A.The purpose of a saddle is to improve the rider's safety, security, and comfort, while distributing the forces exerted by the rider and saddle over a large area of the horse's back without focal pressure points. This study investigates the effects on rider stability of an innovative saddle design that differs from a conventional saddle in having no flaps. Five horses were ridden by their regular rider in their usual saddle and in a flapless saddle. A pressure mat (60 Hz) placed between the saddle and the horse's back was used to determine the position of the center of pressure, which represent...
Steinhoff-Wagner J.Coat clipping is a common practice in sport horses; however, timing, purpose, technique, and clips vary widely, as do the management and feeding of a clipped horse. The aim of this study was to collect data regarding common clipping practices. A questionnaire was published online in Germany and contained 32 questions. Four hundred ninety-eight people answered at least one question, and 373 individuals (7% male, 93% female; ages 14-59 years) completed all the questions. Clipped horses were predominantly used as sport horses (68%), and they were either clipped immediately before or during the w...
McGreevy P, Berger J, de Brauwere N, Doherty O, Harrison A, Fiedler J, Jones C, McDonnell S, McLean A, Nakonechny L, Nicol C, Preshaw L, Thomson P....The aim of this study was to conduct a series of paper-based exercises in order to assess the negative (adverse) welfare impacts, if any, of common interventions on domestic horses across a broad range of different contexts of equine care and training. An international panel (with professional expertise in psychology, equitation science, veterinary science, education, welfare, equestrian coaching, advocacy, and community engagement; = 16) met over a four-day period to define and assess these interventions, using an adaptation of the domain-based assessment model. The interventions were consid...
DuBois C, Hambly-Odame H, Haley DB, Merkies K.As part of a larger Delphi survey project, equine professionals ( = 14) were presented with twelve short scenarios in which a horse's welfare could be compromised. They were asked to rank each scenario (with 0 indicating no welfare concerns and 5 indicating a situation where immediate intervention was necessary), provide justification for their ranking, and give examples of what might have been the motivation behind the scenario. The wide range within vignette scores demonstrated the diversity of opinion even among a relatively small group of equine professionals. Qualitative analysis of respo...
Merkies K, Nakonechny L, DuBois C, Derisoud E.Training practices may impose restrictions on the equine behavioral repertoire through the use of training equipment. Presently, the prevalence of the use of training equipment in Canada is unknown. Through an online survey for horse enthusiasts (n = 654), this study evaluated the prevalence and predominant uses of whips, spurs, and head-control equipment by enthusiasts with direct contact with horses compared to perceptions held by enthusiasts with no direct horse contact using chi-squared analyses. Respondents primarily reported using whips and spurs to augment rider or trainer cues and re...
Kydd E, Padalino B, Henshall C, McGreevy P.Natural Horsemanship is popular among many amateur and professional trainers and as such, has been the subject of recent scientific enquiry. One method commonly adopted by Natural Horsemanship (NH) trainers is that of round pen training (RPT). RPT sessions are usually split into a series of bouts; each including two phases: chasing/flight and chasing offset/flight offset. However, NH training styles are heterogeneous. This study investigated online videos of RPT to explore the characteristics of RPT sessions and test for differences in techniques and outcomes between amateurs and professionals...
Horseman SV, Hockenhull J, Buller H, Mullan S, Barr AR, Whay HR.The equine industry in Great Britain has not been subject to the same pressures as the farming industry to engage with welfare assessment, but this may change as concern about equine welfare increases. Stakeholder attitudes toward welfare assessment may impact the implementation of welfare assessment practices. Focus-group discussions regarding welfare assessment were conducted with 6 equine stakeholder groups: leisure horse owners (caregivers; n = 4), grooms (n = 5), veterinary surgeons (n = 3), welfare scientists (n = 4), welfare charity workers (n = 5), and professional riders (n = 4). Thre...
Martin P, Cheze L, Pourcelot P, Desquilbet L, Duray L, Chateau H.Many factors associated with the saddle and the rider could produce pain in horses thus reducing performance. However, studies of horse-saddle-rider interactions are limited and determining their effects remains challenging. The aim of this study was to test a novel method for assessing equine thoracic and lumbar spinal movement under the saddle and collect data during trotting. Back movement was measured using inertial measurement units (n = 5) fixed at the levels of thoracic vertebrae T6, T12 and T16, and lumbar vertebrae L2 and L5. To compare unridden and ridden conditions, three horses...
Doherty O, Conway T, Conway R, Murray G, Casey V.Noseband tightness is difficult to assess in horses participating in equestrian sports such as dressage, show jumping and three-day-eventing. There is growing concern that nosebands are commonly tightened to such an extent as to restrict normal equine behaviour and possibly cause injury. In the absence of a clear agreed definition of noseband tightness, a simple model of the equine nose-noseband interface environment was developed in order to guide further studies in this area. The normal force component of the noseband tensile force was identified as the key contributor to sub-noseband tissue...
Whishaw IQ, Kolb B.A human physical asymmetry is the near 90% clockwise occipitoparietal scalp hair-whorl direction in Europeans, an incidence that approximates the left lateralization of speech and right-handedness. Hair-whorl direction is also asymmetric in horses, Equus ferus caballus and placement is proposed to be related to temperament and lateralized skill in equitation manoeuvres. We describe a hair-whorl asymmetry in the horse, mane direction. Of 526, 3-year-old American Quarter horses, 69% of horses had mane directed to the right and 31% had mane directed to the left. The bias was larger in females, wi...
Voigt MA, Hiney K, Richardson JC, Waite K, Borron A, Brady CM.The purpose of this study was to gain a better understanding of stock-type horse show competitors' understanding of welfare and level of concern for stock-type show horses' welfare. Data were collected through an online questionnaire that included questions relating to (a) interest and general understanding of horse welfare, (b) welfare concerns of the horse show industry and specifically the stock-type horse show industry, (c) decision-making influences, and (d) level of empathic characteristics. The majority of respondents indicated they agree or strongly agree that physical metrics should b...
Kang OD, Yun YM.The present study aims to confirm the influence of a horse-riding lesson program (HRLP) on the stress level of horses and riders by respectively analyzing their salivary cortisol concentration. Twenty-four healthy horses and 23 riders participated in this study. The horses were randomly classified into two groups for the horse riding lesson program: Class 1 (for the beginner lesson) and Class 2 (for the intermediate lesson). The Class 1 group consisted of 12 horses and 12 riders, while the Class 2 group consisted of 12 horses and 11 riders. Salivettes cotton wool swabs were used for saliva col...
Starling M, McLean A, McGreevy P.Equitation science is an evidence-based approach to horse training and riding that focuses on a thorough understanding of both equine ethology and learning theory. This combination leads to more effective horse training, but also plays a role in keeping horse riders and trainers safe around horses. Equitation science underpins ethical equitation, and recognises the limits of the horse's cognitive and physical abilities. Equitation is an ancient practice that has benefited from a rich tradition that sees it flourishing in contemporary sporting pursuits. Despite its history, horse-riding is an a...
Martin P, Cheze L, Pourcelot P, Desquilbet L, Duray L, Chateau H.Knowledge about the horse-saddle-rider interaction remains limited. The aim of this study was to compare the effect of the rider׳s position at rising trot on the pressure distribution, spine movements, stirrups forces and locomotion of the horse. The horse׳s back movements were measured using IMUs fixed at the levels of thoracic (T6, T12, T16) and lumbar (L2, L5) vertebrae, the pressure distribution using a pressure mat and stirrups forces using force sensors. The horse׳s and rider׳s approximated centres of mass (COM) were calculated using 2D reflective markers. To compare both trot phases...
Egenvall A, Roepstorff L, Eisersiö M, Rhodin M, van Weeren R.The use of tack (equipment such as saddles and reins) and especially of bits because of rein tension resulting in pressure in the mouth is questioned because of welfare concerns. We hypothesised that rein tension patterns in walk and trot reflect general gait kinematics, but are also determined by individual horse and rider effects. Six professional riders rode three familiar horses in walk and trot. Horses were equipped with rein tension meters logged by inertial measurement unit technique. Left and right rein tension data were synchronized with the gait. Results: Stride split data (0-100 %) ...
Thompson K, McGreevy P, McManus P.While the importance of improving horse-related safety seems self-evident, no comprehensive study into understanding or reducing horse-related risk has been undertaken. In this paper, we discuss four dimensions of horse-related risk: the risk itself, the horse, the rider and the culture in which equestrian activities takes place. We identify how the ways in which risk is constructed in each dimension affects the applicability of four basic risk management options of avoidance, transference, mitigation and acceptance. We find the acceptance and avoidance of horse-related risk is generally high,...
Baragli P, Padalino B, Telatin A.Horses were domesticated 6000 years ago and since then different types of approaches have been developed to enhance the horse's wellbeing and the human-horse relationship. Even though horse training is an increasingly important research area and many articles have been published on the subject, equitation is still the sport with the highest rate of human injuries, and a significant percentage of horses are sold or slaughtered due to behavioral problems. One explanation for this data is that the human-horse relationship is complex and the communication between humans and horses has not yet been...
Payne E, Boot M, Starling M, Henshall C, McLean A, Bennett P, McGreevy P.This review collates peer-reviewed evidence for desirable attributes for those who work with dogs and horses. It is written with a particular focus on the veterinary profession. Although veterinarians and veterinary nurses (VNs) occupy variable roles when interacting with their patients, several behavioural attributes emerge as helpful across the range of such roles. In light of recent research on the value of considering animals' arousal and affective state as predictors of behaviour and welfare, best practice in human-horse and human-dog-interactions is outlined. The attributes of affiliatio...
Byström A, Roepstroff L, Geser-von Peinen K, Weishaupt MA, Rhodin M.Collection is a central term in equine dressage, defined as a shortening of the horse's stride length with retained energy and hind limb activity. How collection is induced by the rider has yet not been investigated objectively. The aim of this study was therefore to compare the movement pattern of high-level dressage riders between free trot (loose reins), passage and a range of three speeds in collected trot. Both at higher speed in collected trot and in passage, the rider's pelvis became more caudally rotated and the rider's lumbar back became more flexed. However, in passage there was also...
Viry S, De Graaf JB, Frances JP, Berton E, Laurent M, Nicol C.The relationship between the biomechanical horse–rider interaction and endurance race performance requires further investigation. Objective: To characterise, both quantitatively and qualitatively, elite and advanced horse–rider dyads on the basis of the biomechanical horse–rider interaction during endurance races. Methods: Five elite and 5 advanced horse–rider dyads were recorded during CEI*/CEI** endurance races using 2 synchronised triaxial accelerometers each placed close to horse and rider centres of mass. Methods: For each horse–rider dyad, analyses focused on the vertical displ...
Alexander J, Hobbs SJ, May K, Northrop A, Brigden C, Selfe J.To observe postural characteristics of female dressage riders, through application of three-dimensional motion analysis and to assess the effects of athletic taping on postural asymmetry during sitting trot. Methods: Randomised cross-over. Methods: Data collection took place at Myerscough Agricultural College in an indoor riding area. Methods: Ten healthy female experienced dressage riders participated. Methods: Movement kinematics of the trunk and pelvis, pre and post taping intervention. Results: Riders presented pre-intervention with asymmetric movement characteristics through dynamic obser...

Stomp M, Masson A, Henry S, Hausberger M, Lesimple C.Several previous studies have shown that working conditions (including riding) can induce stress in horses. Riders' actions and postures, when inappropriate, induce stress and conflict behaviours during riding and welfare impairment and negative emotional states outside work. Optimistic biases have been found in leisure horses, which, amongst positive management factors, were ridden with loose reins and low hands. Thus, one can wonder whether horses may positively perceive work or parts of it. Indicators of positive emotions are poorly known yet but we recently found that, out of the working c...
Wilkins CA, Nankervis K, Protheroe L, Draper SB.Static assessment and grouping of riders by competition level are prevalent in equestrian coaching practice and research. This study explored sagittal pelvic tilt in 35 competitive dressage riders to analyse the relationship between static and dynamic postures and assess the interaction of competition level. Riders were assessed using optical motion capture on a riding simulator at halt and in walk, trot, and left and right canter. Mean, minimum and maximum pelvic tilt, and range of motion (ROM) were measured as the pitch rotation of a rigid body formed by markers placed on the rider's left/ri...
Roepstorff L, Johnston C, Drevemo S, Gustås P.According to riding texts, draw reins are supposed to support increased collection. This has not been measured objectively. Therefore, the objective of this study was to determine whether a horse ridden with draw reins would relatively increase weightbearing of the hindquarters while worked with the draw reins compared to a normal rein. Ground reaction forces were measured in 8 horses at the slow trot over a force plate in 3 different experimental set-ups: 1) riding with only a draw rein (DR); 2) riding with the combination of a normal and a draw rein (NR-DR) and 3) riding with a normal rein (...
Fenner K, Dashper K, Wilkins C, Serpell J, McLean A, Wilson B, McGreevy P.Over the last decade, equitation scientists have increasingly relied on online survey tools to gather information on horse training, management, behaviour and other equine-related subjects. With a detailed knowledge of their animals, horse owners and riders are ideally placed to contribute to research but are sometimes reluctant to engage with and devote time to surveys. The current article reveals, through consultation with stakeholder groups, the potential of a range of motivational items to boost horse-owner participation. A short, three-question inquiry was developed to rank respondents' (...
Zeyner A, Harmeyer J.L-carnitine, a betaine derivative of beta-hydroxybutyrate, is found in virtually all cells of higher animals and also in some microorganisms and plants. In animals it is synthesized almost exclusively in the liver. Two essential amino acids, i.e., lysine and methionine serve as primary substrates for its biosynthesis. Also required for its synthesis are sufficient amounts of vitamin B6, nicotinic acids, vitamin C and folate. The first discovered ergogenic function of L-carnitine is the transfer of activated long-chain fatty acids across the inner mitochondrial membrane into the mitochondrial m...
Blokhuis MZ, Aronsson A, Hartmann E, Van Reenen CG, Keeling L.A correct seat and position are the basis for a good performance in horseback riding. This study aimed to measure deviations from the correct seat, test a seat improvement program (dismounted exercises), and investigate whether horse behavior was affected by the rider's seat. Five experienced trainers defined 16 seat deviations and scored the occurrence in 20 riders in a dressage test. Half the riders then carried out an individual training program; after 9 weeks, riders were again scored. The study took no video or heart-rate recordings of horses and riders. Panel members did not agree on the...
DuBois C, Hambly Odame H, Haley DB, Merkies K.The diversity of sectors that comprise the equine industry makes reaching a consensus regarding welfare issues a challenge. To allow for productive discussion, equine professionals (n = 34) chosen to represent the diverse specializations from across Canada were surveyed using the Delphi technique-a survey technique employing multiple, iterative "rounds" to consolidate viewpoints-to gather and consolidate information regarding areas of welfare concern in the Canadian equine industry. Only participants who completed the prior round could participate in subsequent rounds. In the first round, resp...
Fine AH, Andersen SJ.The field of human-animal interactions and, more specifically, animal-assisted interventions and equine assisted interactions (equine assisted interactions have significantly evolved over the past half century. The primary purpose of this paper is to provide a brief commentary of both fields and the challenges they are presently experiencing as they move forward in their future. More specifically within this commentary, attention will be given to highlighting some of the directions taken in both fields, including clarifying their terminology as it applies to scope of practices, trends in resea...
Rose RJ.Over the last 10 years, there has been a great increase in information on the physiological effects of endurance exercise in horses reflecting the increase in popularity of endurance riding throughout the world. This review, which is in two parts, examines energy considerations, fluid and electrolyte balance, acid-base balance, hormonal and metabolic changes, muscle function, renal and hepatic function, haematological changes and clinical problems encountered in endurance rides. Additionally, relevant information from studies in man is included.
Panzani D, Rota A, Pacini M, Vannozzi I, Camillo F.One year old fillies are able to conceive but, usually, not to give birth to a living foal. Although embryo transfer allows the production of foals from mature mares with repeated pregnancy losses, no reports are available on the use of one year old fillies as embryo donors. To evaluate this possibility, eleven 12-16 months old Haflinger mares were inseminated with fresh semen and subjected to embryo recovery. Some of the recovered embryos were non-surgically transferred into synchronized mature recipients. Pregnancies were terminated using PGF2alpha at day 25. Fillies' embryo recovery rate an...
Baxter J, Hobbs SJ, Alexander J, George LS, Sinclair J, Chohan A, Clayton HM.In equestrian sports the novice rider learns first to follow the movements of the horse's back and then how to influence the horse's performance. One of the rider's challenges is to overcome inherent horse and/or rider asymmetry patterns when riding in straight lines, mirroring the movements on the left, and right sides when turning. This study compares the performance of novice and advanced riders when riding in sitting trot on straight lines and when riding shoulder-in to the left and right sides. Eight novice and eight advanced horse-rider combinations performed sitting trot in a straight l...
Thompson K, McManus P, Stansall D, Wilson BJ, McGreevy PD.The idea that whip use is critical to thoroughbred racing integrity is culturally entrenched but lacks empirical support. To test the longstanding beliefs that whip use aids steering, reduces interference, increases safety and improves finishing times, we conducted a mixed-method analysis of 126 race reports produced by official stewards of the British Horseracing Authority, representing 1178 jockeys and their horses. We compared reports from 67 "Hands and Heels" races, where whips are held but not used (whipping-free, WF), with 59 reports from case-matched races where whipping was permitted (...
Camp M, Kibler ML, Ivey JLZ, Thompson JM.Racehorse welfare is a prominent, public issue which affects nearly every aspect of the racing industry. Thoroughbred care after race career completion has garnered increasing attention from the equine industry, general public, and animal welfare groups alike. As the average racehorse's career lasts just 4.5 years, owner demand for thoroughbreds is essential for post-race careers and acceptable welfare standards. This study utilized data from and hedonic pricing models to analyze buyer demand for thoroughbreds sold in online auctions held from 2012 to 2020. The results indicate buyer preferenc...
Tilley P, Simões J, Sales Luis JP.From previous studies, the International Society for Equitation Science has advised that further research be conducted on the physiological/psychological effects of less-exacerbated poll flexion angles. We aimed to evaluate the effects of two riding poll flexion positions with a difference of only 15° on the respiratory systems and behaviour of horses through an evaluation of dynamic airway collapse via over-ground endoscopy, the pharyngeal diameter, pleural pressure, arterial oxygenation and lactate, HR/RR, and the occurrence of conflict behaviours. Twenty high-level dressage and twenty show...

Alexander J, Hobbs SJ, May K, Northrop A, Brigden C, Selfe J.To observe postural characteristics of female dressage riders, through application of three-dimensional motion analysis and to assess the effects of athletic taping on postural asymmetry during sitting trot. Methods: Randomised cross-over. Methods: Data collection took place at Myerscough Agricultural College in an indoor riding area. Methods: Ten healthy female experienced dressage riders participated. Methods: Movement kinematics of the trunk and pelvis, pre and post taping intervention. Results: Riders presented pre-intervention with asymmetric movement characteristics through dynamic obser...
Hessler C, Schilling B, Meenen NM, Lockemann U, Püschel K.Equitation is associated with a high rate of injuries and lethal accidents. The head is the most frequently concerned body part. Hence in the majority of the cases deaths results from head injuries. In this study injuries as well as causes of deaths were analyzed in 21 cases. Actual safety standards in equitation were appraised and suggestions for improvement were formulated. Methods: Between 1996 and 2008 21 equestrians suffered from a fatal accident in the greater area of Hamburg. In a retrospective analysis, equestrians' records which bases on the documentation of the institute of forensic ...
Douglas J, Owers R, Campbell MLH.The concept of 'social licence to operate' (SLO) is relevant to all animal-use activities. An SLO is an intangible, implicit agreement between the public and an industry/group. Its existence allows that industry/group to pursue its activities with minimal formalised restrictions because such activities have widespread societal approval. In contrast, the imposition of legal restrictions-or even an outright ban-reflect qualified or lack of public support for an activity. This review discusses current threats to equestrianism's SLO and suggests actions that those across the equine sector need to ...
Northrop AJ, Dagg LA, Martin JH, Brigden CV, Owen AG, Blundell EL, Peterson ML, Hobbs SJ.A link between surface characteristics and injury has been identified in equine disciplines. Maintenance procedures are reported to affect surface characteristics and could influence horse movement. The study investigated limb and hoof movement on a synthetic surface following two different preparations (harrowing and rolling). Nine horses were recorded using infrared cameras and retro-reflective markers at walk, trot and canter on two surface preparations in a cross-over design. Hoof rotation and displacement, metacarpophalangeal joint (MCPJ) extension and third metacarpal (McIII) inclination...
Clayton HM, MacKechnie-Guire R.Not too long ago, tack often fell into the "one size fits all" category but, fortunately, times have changed. In recent years, tack has become not only more functional but also a fashion statement. This article describes scientific concepts of the saddle, bridle, and bit with emphasis on clinical signs associated with ill-fit or incorrect use.
Egenvall A, Clayton H, Engell MT, Roepstorff C, Engström H, Byström A.The study investigated between-rider differences in pelvic roll and pitch motion during horseback riding as the horse walked around circles without rein contact (walk on long reins), with rein contact, and with moderate collection. Ten horses were ridden by five riders on left and right 10 m circles, in a partly crossed design, yielding 14 trials. Each trial included each of the three walk variations in both directions. Riders wore an inertial measurement unit (IMU), logging at 100 Hz, dorsally on the pelvis. Pelvic roll and pitch data were split into strides based on data from IMU-sensors on ...
Gille C, Kayser M, Spiller A.Whereas in former times horses were reserved primarily for people involved in agriculture, elite equestrians or the military, nowadays equestrian sport has become an activity for people with a wide variety of backgrounds. However, as more and more people become involved with equestrian sport today, the knowledge concerning animal husbandry in general is diminishing due to an alienation from agricultural themes in modern societies. As a consequence, this development affects both riding ability and the appraisal of horses, especially with respect to the purchase of horses. In order to analyse wh...
Cook WR, Mills DS.The study tested the null hypothesis that if a horse is ridden in a snaffle bridle and then a crossunder bitless bridle, there will be no change in its behaviour. It was predicted that there would be change and that behaviour would improve when bitless. Four horses, none of which had ever been ridden in a crossunder bitless bridle, were ridden through two 4 min, exercise tests, first bitted then bitless. An independent judge marked the 27 phases of each test on a 10 point scale and comments and scores were recorded on a video soundtrack. The results refuted the null hypothesis and upheld the p...
MacKechnie-Guire R, Fisher M, Pfau T.Using a half pad beneath a saddle can be beneficial for improving saddle fit. However, there is a paucity of evidence on half pad use when used beneath a correctly fitted saddle. The aim was to quantify the effect that three different half pads have on pressure distribution beneath a saddle fitted following industry guidelines. Twelve nonlame horses were ridden by experienced riders in sitting trot and canter on each rein (three repeats). Saddle fit, with a high-withered cotton saddle cloth (control) compared with three half pads (viscoelastic gel, wool, and medical-grade, closed-cell foam), w...
