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.
Gunst S, Dittmann MT, Arpagaus S, Roepstorff C, Latif SN, Klaassen B, Pauli CA, Bauer CM, Weishaupt MA.Asymmetric forces exerted on the horse's back during riding are assumed to have a negative effect on rider-horse interaction, athletic performance, and health of the horse. Visualized on a saddle pressure mat, they are initially blamed on a nonfitting saddle. The contribution of horse and rider to an asymmetric loading pattern, however, is not well understood. The aim of this study was to investigate the effects of horse and rider asymmetries during stance and in sitting trot on the force distribution on the horse's back using a saddle pressure mat and motion capture analysis simultaneously. D...
Jastrzębska E, Wilk I.The aim of the study was to determine the effect of selected rider-related factors (riders' age and experience, type of preparatory activities, test variant) on the behaviour of recreational horses being prepared for use. Six adult, hot-blooded recreational horses were handled by two female riders that the horses knew and by another two that the horses did not know (two of them were aged 12 and two aged 30). The horses were assessed by a behaviourist for their behaviour during the pre-training activities (entering the box, grooming, cleaning the hooves, bridling, saddling up, taking a horse to...
Funakoshi R, Masuda K, Uchiyama H, Ohta M.The study aimed to clarify the regularity of the motions of horse's back, rider's pelvis and spine associated with improvement of rider's dynamic trunk alignment. The study used a crossover design, with exercise using the horseback riding simulator (simulator hereafter) as the control condition. The experiments were conducted at Tokyo University of Agriculture Bio-therapy Center. The sample consisted of 20 healthy volunteers age 20-23 years. Participants performed 15-min sessions of horseback riding with a Hokkaido Pony and exercise using the simulator in experiments separated by ≥2 weeks. S...
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...
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 %) ...
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 ...
Clayton HM, Murray R, Williams JM, Walker V, Fisher M, Fisher D, Nixon J, Mackechnie-Guire R.Noseband adjustment should avoid discomfort and allow some jaw movement. Objective: To determine pressure beneath a cavesson noseband at five tightness levels during standing and chewing. It was hypothesised that increased noseband tightness is associated with increases in nasal and mandibular pressures while standing and chewing, accompanied by increases in eye temperature and blink rate. Methods: Experimental. Methods: Eight highly-trained dressage horses wore a snaffle bridle with their own bit. Pressure mats over the nasal bones and beneath the mandibular rami recorded sub-noseband pressur...
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...
Pearson G, Connor M, Keen J, Reardon R, Waran N.Working as an equine veterinarian carries a high risk of occupational injury, with the behavior of the horse frequently reported as a cause for these injuries. Risk of injury is one reason cited by undergraduate veterinary students that would prevent them from entering large animal practice, and newly graduated veterinarians have been shown to be at increased risk of sustaining an occupational injury compared with more experienced colleagues. A cohort of pre-final-year undergraduate veterinary students were given a 45-minute lecture on learning theory and its application in equine practice, co...
Patterson M, Doyle J, Cahill E, Caulfield B, McCarthy Persson U.Horse rider ability has long been measured using horse performance, competition results and visual observation. Scientific methods of measuring rider ability on the flat are emerging such as measuring position angles and harmony of the horse-rider system. To date no research has quantified rider ability in show jumping. Kinematic analysis and motion sensors have been used in sports other than show jumping to measure the quality of motor control patterns in humans. The aim of this study was to quantify rider ability in show jumping using body-mounted IMUs. Preliminary results indicate that ther...
Martins JN, Silva SR.Equitation is a cause of physiological stress in the equine athlete, and personality is a factor generally associated with the different responses of equines to stressors. This study explored ocular temperature, measured via infrared thermography, associated with personality and stress in horses submitted to dressage exercising in riding lessons, ridden training and lunging. Infrared thermograms of 16 horses were taken before and after sessions using an FLIR F4 camera (FLIR Systems AB, Sweden) to determine maximum eye surface IRT temperature (IRTmax), and total training time was registered (T)...
Kuhnke S, König von Borstel U.The present study aimed to assess an agreement between established and novel methods to determine laterality and to identify the distribution of laterality in warmbloods and Thoroughbreds. Nine different methods to investigate a horses' laterality outside a riding context and during riding were compared across two groups of horses (sample A: 67 warmblood- type horses, sample B: 61 Thoroughbreds). Agreement between any two methods was assessed by calculating Cohen's kappa with McNemar's test or Bowker's Test of Symmetry, and the deviation from equal distributions was assessed with chi2-tests. C...

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...
Eisersiö M, Byström A, Yngvesson J, Baragli P, Lanata A, Egenvall A.When a rider maintains contact on the reins, rein tension will vary continuously in synchronicity with the horse's gait and stride. This continuous variation makes it difficult to isolate the rein tension variations that represent a rein tension signal, complicating interpretation of rein tension data from the perspective of horse-rider interaction. This study investigated (1) the characteristics of a rein tension signal and (2) horse response to a rein tension signal for backing, comparing pressure applied by a bit (bridle), or by a noseband (halter). Twenty Warmblood horses (10 young, 10 adu...
Bye TL, Lewis V.This study explored the relationship between footedness and postural asymmetry in equestrian riders. 28 female riders completed the Waterloo Footedness Questionnaire- Revised (WFQ-R), giving a score for footedness. They then took part in a test on a riding simulator where measures of saddle force, stirrup force, and degree of lateral tilt of the pelvic, trunk, and shoulder segments were taken over a period of 20 seconds in trot. Symmetry indices were calculated for stirrup force and saddle force. There were no significant correlations between WFQ-R score and any of the measures of postural sym...
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...
