Topic:Equitation Science
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.

Methods: An online questionnaire was distributed via mailing lists and WhatsApp; 116 complete responses from breeding operations were collected and analysed. The focus was on management of the breeding facility, and stallion welfare indicated by management, handling and housing. Results: Respondents were from Europe (40....
How obstacle approach shapes rider biomechanics: Changes in kinematics, rein tension and stirrup forces during canter. Show jumping performance depends on the rider's ability to regulate the horse-rider system while maintaining postural stability under dynamic constraints. Although rider biomechanics has been investigated in various equestrian contexts, integrated analyses combining 3D kinematics with rein and stirrup kinetics during jump-approach remain limited. This study aimed to analyse how approaching an obstacle changes a rider's control strategies by comparing sitting canter, two-point canter in straight line without obstacle and jump-approach canter (defined here as the five strides before obstacle) in...
A Global Structural Variation Map Reveals Novel Variants for Body Conformation and Racing Ability in Horses. The selection of horses has been instrumental in shaping long-range mobility, advancing warfare strategies, and diversifying equine phenotypes. However, the structural variants (SVs) favored by this process remain largely unexplored. Utilizing high-fidelity Pacific Biosciences sequencing, we assembled three high-quality horse genomes, incorporating 237 Mb (9.48%) of novel sequences relative to the existing reference genome. These assemblies achieved an average Benchmarking Universal Single-Copy Orthologs completeness of 95.1%. By employing a graph-based approach, we genotyped 23,163 high-con...
In-Hand Training of Piaffe and Passage with Leg Stimulation: A Literature-Based Biomechanical Argument for Why This Method Fails to Produce True Collection. In-hand training of piaffe and passage via tactile leg stimulation (Handarbeit mit Touchieren) is widely practised in dressage, yet consistently produces horses that elevate their legs without achieving collection - a pattern termed Schenkelgänger (leg-movers) in classical German equitation. Based on published kinetic, kinematic, and electromyographic literature, this review argues that tactile leg stimulation activates the spinal nociceptive withdrawal reflex, an unloading movement mechanistically opposed to the elastic tendon rebound and ventral muscular chain activation that define true co...
Machine learning-based gait classification and genome-wide association identify a QTL for gait type in Colombian paso horses. Coordinated mammalian locomotion relies on spinal circuits where regulates strides and alternative gaits. However, does not explain differences between the Colombian paso horse breed's specialized gaits, Colombian trocha and Colombian trot. We used inertial sensors and machine learning to develop accurate phenotyping ( = 225 horses), before performing genome-wide association analysis ( = 85 horses, 670K array). We identified a 2.43 Mb quantitative trait locus (QTL) on ECA16, where haplotypes featuring lead variants (rs1147402472, = 1.95 × 10; rs1136628503, = 8.52 × 10) explained 48.6% of...
A multimodal approach to equine thoracolumbar myofascial pain: integrating clinical examination, AI-based gait analysis, and the ridden horse pain ethogram. Myofascial pain syndrome (MPS) is considered highly prevalent in horses, yet it is frequently underdiagnosed due to limited understanding of its clinical presentation and functional consequences, as well as the inherent challenges associated with its clinical assessment and objective measurement. In equines, the relationship between palpation-based MPS indicators, gait asymmetries, and pain-related behaviours during ridden work remains unclear. The primary aim of this study was to evaluate the association between thoracolumbar palpation pain scores and gait asymmetries measured in-hand and dur...
Positive Reinforcement (R+) Horse Training in Practice: Evaluation of Online Trailer-Training Demonstrations. Operant conditioning that includes primarily positive reinforcement (R+) has been shown to be an effective and welfare-friendly method of training horses. Despite this, operant conditioning and R+ are not fully understood by many horse trainers who claim to advocate for its use. Anecdotal observations suggest that some professional trainers who claim to use R+ do not use R+ primarily, even in publicly offered educational demonstrations. To better understand readily available training materials regarding the use of R+ with horses, we reviewed a sample of 20 online trailer-training demonstration...
Synchronization dynamics between rider and saddle motion across gaits revealed by IMU analysis. Effective rider-horse coordination is essential for performance and welfare, yet objective, field-based quantification of rider-saddle synchronization across gaits remains limited. Objective: To quantify dynamic synchronization between rider motion and saddle motion (as a proxy for horse trunk oscillations) across walk, trot, and canter using a minimal inertial measurement unit (IMU) setup, and to determine whether synchronization differs between rider body segments. Methods: Two experienced riders (8-20 years riding experience) rode their own or familiar warmblood horses (n = 2; age 6-14 year...
Social enrichment mitigates facial expressions and physiological indicators of short-term stress in horses. This study aimed to evaluate the ability of social noncontact environmental enrichment to facilitate social buffering and to characterize the emotional experience of horses subjected to restraint in stock by assessing physiological parameters and facial expressions. Pantaneiro horses (n = 11) were evaluated in a crossover design with two treatments: social noncontact enrichment during stock restraint and social isolation during stock restraint. Physiological parameters (heart rate, heart rate variability, respiratory rate, ocular temperature by infrared thermography, and auricular temperat...
Progressive structural and functional change in horses: a conceptual framework for systemic equine (patho-)physiology. A wide range of locomotor, postural, and behavioral pathophysiology in horses-often grouped under terms such as Topline Syndrome, Myofascial Dysfunction, or Poor Posture Syndrome-lack a coherent systemic explanation. These presentations share reduced performance, stability, and resilience, yet are commonly managed through isolated symptom-focused interventions. To address this gap, we propose progressive structural and functional change (PSF) as a systemic framework describing progressive reorganization processes within the equine body that link fragmented pathological domains into a coherent ...
Multi-Modal Feature Fusion and Hierarchical Classification for Automated Equine-Human Interaction Behavior Recognition. Automated recognition of equine-human interaction behaviors from video represents a significant challenge in computational ethology, with critical applications spanning animal welfare assessment, equine-assisted services evaluation, and safety monitoring in equestrian environments. Existing approaches to animal behavior recognition typically focus on single species in isolation, rely solely on facial expression analysis while ignoring full-body posture, or employ flat classification architectures that fail under the severe class imbalances characteristic of naturalistic behavioral datasets. Fu...
Do active stables affect the response to novelty and attitude towards humans in horses? A pilot study. The demand for horse housing that allows social contact, free movement, and continuous access to forage is increasing. Active stables, equipped with automatic feeders, aim to meet these needs by offering conditions closer to natural living. It is not known whether 'active stable' influences horse fear and human-oriented behaviour. This study compared the behaviour of horses housed in active stable (N = 24) and traditional stable (N = 22) to assess responses to novelty, sudden stimuli, and interactions with humans. We also examined the effects of breed type, age, and weekly riding workload....
Facial hair whorl location, behavior, and ocular temperature as a physiological stress indicator in young Pura Raza Española dressage horses. Behavioral and emotional reactivity assessment in sport horses is essential for optimizing their management and sports performance, particularly in equestrian disciplines such as Dressage. This study investigates, in Pura Raza Española (PRE) horses, the association between facial hair whorl (FHW) patterns, behavioral traits, and physiological stress responses using ocular temperature (OT) assessed with infrared thermography as, an objective, non-invasive physiological stress indicator. Unassigned: A total of 98 male PRE horses, aged 4-6 years old and all gray coated, were evaluated during the...
Upwards or onwards? Assessment of objective gait quality parameters in three European horse breeds at walk and trot. Europe has many horse breeds differing in conformation, gaits and genetics due to diverging breeding goals. Research studies comparing objective gait parameters between different horse breeds are limited and date back a decade. Objective: In this study, objective gait parameters were measured in three European breeds, namely Lusitanos (LUS; n = 52), Franches-Montagnes (FM; n = 311) and Swiss Warmblood (WB; n = 40) using an inertial measurement system (sensors at poll, withers, pelvis and all four canon bones) at walk and trot. Results: At walk and trot, LUS moved significantly slower than WB a...
Changes in Fitness Parameters in Ridden Trained Showjumping Horses After Healing of Gastric Ulcers: Preliminary Results. Equine Gastric Ulcer Syndrome (EGUS) is a worldwide disease described in different categories of animals. A causal relationship between exercise and EGUS has been suggested, attributed to stress as well as physiological changes in the position of abdominal organs, especially during trot and gallop. EGUS can influence athletic fitness, as has been described in various papers on racehorses. The aim of this work was to determine if gastric ulcer healing is associated with changes in selected fitness parameters (i.e., speed, heart rate during exercise and recovery, stride length and frequency) in ...
Horses show limited owner bias in reunion and odor tests: a pilot study. Compared to other companion animals, our understanding of the human-horse relationship is limited, particularly from the horse's perspective. This pilot study examined whether horses (N = 30) show a bias towards their owner in a reunion in the presence of both the owner and a stranger. Afterwards, the horses were also presented with the odor of the owner and a stranger. Both tests were video recorded for behavioral analyzation. No significant owner-directed bias was observed at the group level in either the reunion test or the odor test. Nonetheless, in the reunion test, owner bias in physical...
What if Horses Were Humans? Comparing Rein Tension and Bit Pressures to Human Pressure Pain Thresholds. Bit pressure and rein tension-induced mouth pain in horses have recently become a significant welfare concern, fueling debates within the equestrian community and beyond. Evidence indicates that bits can cause pain-related behaviors and even oral lesions. Although studying pressure-induced pain in animals is challenging, the similarities in the physiology of pain processing (nociception) across mammals suggest that it is reasonable to assume that pain perception in humans and horses is principally comparable. Therefore, we compared human pressure pain detection thresholds (PPDTs) to reported r...
Evaluation of Owner-Reported Clinical Signs and Fecal Occult Blood Tests as Predictors of Equine Gastric Ulcer Syndrome in Competition Dressage Horses. Equine gastric ulcer syndrome (EGUS) adversely affects the health, welfare, and performance of sports horses, requiring gastroscopy for definitive diagnosis. Owners frequently consider girth aversion as highly suggestive of EGUS. Objective: To evaluate whether owner-reported clinical signs or fecal occult blood tests (FOBTs) can help identify horses needing gastroscopy for EGUS diagnosis or monitoring treatment, thereby reducing unnecessary procedures in unaffected horses. Methods: Eighty competition dressage horses referred by veterinarians for EGUS evaluation. Methods: Case-control study in...
Prevalence of Low Back Pain in Competitive Dressage Riders: A Cross-Sectional Study. Objective: The purpose of this study was to identify the point and lifetime prevalence of low back pain (LBP) among dressage riders and identify riding-related variables that may precipitate LBP.Methods: A cross-sectional, exploratory, quantitative study was conducted using an online questionnaire. One hundred dressage riders competing at preliminary and higher levels were recruited at the South African Equestrian Federation's registered shows. Frequencies and descriptive statistics were performed on each question in addition to cross-tabulations for associations between variables or differenc...
Quantification of the Effect of Saddle Fitting on Rider-Horse Biomechanics Using Inertial Measurement Units. The saddle's adaptability to the rider-horse pair's biomechanics is essential for equestrian comfort and performance. However, approaches to dynamic evaluation of saddle fitting are still limited in equestrian conditions. The purpose of this study is to propose a method of quantifying saddle adaptation to the rider-horse pair in motion. Eight rider-horse pairs were tested using four similar saddles with small modifications (seat depth, flap width, and front panel thickness). Seven inertial sensors were attached to the riders and horses to measure the active range of motion of the horses' forel...
How accurate are riders in assessing saddle position? Recent research has highlighted the detrimental impact of an ill-fitting saddle on equine health, welfare and performance. A correctly fitting saddle may not fit if positioned incorrectly. Objective: This study assessed riders' ability to visually evaluate saddle position and examine factors that influenced accuracy of assessment. Methods: Survey participants were provided with photographs of a series of saddles on horses obtained from the lateral aspect of the left side of the horse. Saddles were either correctly positioned (n = 5), too far forward (n = 5) or too far back (n = 2). This was in...
Tight nosebands apply high pressures on the horses’ face and alter stride kinematics. Noseband tightness has received increasing attention within equitation science, however, there is little research into how this effects equine behaviour or performance. Objective: 1) determine the peak pressures under noseband in vivo at three different tightness; 2) assess limb and back kinematics at different noseband tightness. Methods: Noseband tightness (n = 8 horses) was set using an International Society for Equine Science (ISES) taper gauge with the three settings being; "two fingers (2F)", "one finger (1F)" and "zero fingers (0F)". Peak pressure under noseband was determined using pre...
Using an Equine Cadaver Head to Investigate Associations Between Sub-Noseband Space, Noseband Tension, and Sub-Noseband Pressure at Three Locations. Pressures applied to horses via nosebands are of growing concern. The current study applied noseband pressure to the head of a dead horse. Pressure sensors were placed on the left nasal bone to record pressures as the noseband was progressively tightened. Tightness increased as predicated by holes in the strap of the noseband (as supplied) through eight steps from two fingers' space, assessed using the standard International Society for Equitation Science Taper Gauge through to zero space. Sensors were also placed at the midline frontal plane and intra-orally at the level of the second premola...
Influences of Double Versus Snaffle Bridles on Equine Behaviour at Dressage Competitions and Factors That Interact with Their Effect. Despite welfare concerns, conflict behaviours (indicative of momentary states of acute stress) are common in horses during dressage competitions. Identifying factors that affect conflict behaviours during competition therefore has the potential to improve equine welfare. The aim of this exploratory study was to assess the effect of bridle type (double versus snaffle) in relation to other potential affecting factors (e.g., average head angle, competition level and type, tack variation) on conflict behaviours during dressage competition. An ethogram was created to analyse the conflict behaviour ...
Emotional contagion of fear and joy from humans to horses using a combination of facial and vocal cues. Emotional contagion, the emotional state-matching of two individuals, has been documented in various species. Recent findings suggest emotional contagion could also take place between humans and domestic mammals. However, the range of targeted animal species and human emotions that have been studied is still limited, and the methodology to investigate emotional contagion in this context is not fully established. This study examined emotional contagion of fear and joy from humans to horses by measuring physiological (heart rate, infrared thermography) and behavioral responses (posture, laterali...
The Role of Horses as Instructional and Diagnostic Partners in Riding Lessons. In many types of embodied skills instruction, the learnables-that is, the local and jointly negotiated foci of instruction-emerge from a combination between a pre-existing lesson plan and the spontaneous interaction between teacher and student. Through the analytical lens of Conversation Analysis, this paper investigates the interspecies instruction setting of horse-riding lessons and shows how here, it is not only the human teachers and learners that determine the emergence of new learnables but also the horses. Horses' actions can initiate new courses of action in a lesson, and horses can th...
Marker based and markerless motion capture for equestrian rider kinematic analysis: A comparative study. The study hypothesised that a markerless motion capture system can provide kinematic data comparable to a traditional marker-based system for riders mounted on a horse. The objective was to assess the markerless system's accuracy by directly comparing joint and segment angle measurements taken during walking and trotting with those obtained from a marker-based system. Ten healthy adult participants performed five dynamic trials during walking and trotting. A twelve-camera marker-based system and eight-camera 2D video-based system were synchronised. Three-dimensional hip, knee, shoulder and elb...
Differences between facilities in horse welfare profiles: slight differences in management/working conditions may be enough. Many studies focus on animal welfare in terms of specific, either behavioural or physiological, indicators or on the impact of a particular management factor. However, an animal's welfare state results from the individual's perception of its general environment, which has consequences at both behavioural and physiological levels. Previous research on horses has shown that different riding schools could be characterised by different emotional/cognitive profiles of horses, in relation sometimes with one single management factor. In the present study, we aimed at determining if such facility-spec...
Exploring equine behavior: Wearable sensors data and explainable AI for enhanced classification. Understanding equine behavior through advanced monitoring technologies is crucial for improving animal welfare, optimizing training strategies, and enabling early detection of health or stress-related issues. This study integrates wearable sensor data with Explainable Artificial Intelligence (XAI) techniques, particularly SHAP (Shapley Additive Explanations), to enhance interpretability in equine behavior classification. The data used in this study were sourced from an open-source dataset, ensuring transparency and reproducibility. Orginally, data were collected from 18 horses using sensor dev...
