Topic:Fitness
Fitness in horses refers to the physical condition and performance capability of equines, influenced by factors such as exercise, nutrition, and overall health management. It encompasses a range of physiological attributes, including cardiovascular endurance, muscular strength, flexibility, and metabolic efficiency. Evaluating equine fitness involves assessing parameters such as heart rate, respiratory rate, and recovery times post-exercise. These metrics are used to tailor training regimens and optimize performance for various equestrian disciplines. This page gathers peer-reviewed research studies and scholarly articles that explore the assessment, enhancement, and impact of fitness on equine performance and well-being.
Differences in Stride Characteristics Between Lead and Wheel Horses in Competitive Chuckwagon Racing. In Chuckwagon racing, teams of four Thoroughbreds with two lead horses in front and two wheel horses directly behind pull a 600 kg wagon around a racetrack. Our study focuses on stride parameters that have previously retrospectively predicted impending injuries. We hypothesize that in aid of the initiation of the tight figure-of-eight turn at the start of the race, the more agile lead horses gallop with higher stride frequency (SF) and reduced stride length (SL), and that differences are exacerbated in the initial accelerative race segments. Methods: Speed, SF, and SL were quantified with glob...
Aqua training promotes changes of skeletal muscle mass in show jumping horses. The correct prescription of aquatic treadmill training for equine athletes depends on understanding the muscular changes generated by working in the water.

Unassigned: This retrospective study analyzed a 25-year longitudinal dataset ( = 1,608) from the official Field Performance Test to quantify genetic trends in gait efficiency, using nonparametric methods to assess the effects of test type, year, and age on stride length and speed at the walk and trot. To estimate he...
New Insights in Heart Rate Variability Through Non-Linear Methods for Conditioning Assessment in Horses. Chronic exercise induces significant adaptations across multiple physiological systems due to increased metabolic demand. Heart rate variability (HRV) has emerged as a prominent, non-invasive method for monitoring fitness, enabling inference of sympathovagal balance from time-series variations in electrocardiograms. Notably, nonlinear analyses have a strong capacity to detect and estimate complex mechanisms underlying cardiovascular modulation. In this context, HRV was evaluated in the time and frequency domains, as well as through nonlinear methods, in 12 young purebred Arabian horses undergo...
Race and Final-600 m Speed Response to Distance and Track Condition in Thoroughbred Flat Racing. The temporal and spatial distribution of speed varies with race distance and track condition, influencing where mechanical demand peaks within a race. This study aimed to describe variation in race-day speed with race distance and track condition. Race-day data from 18 flat racing seasons on turf and synthetic surfaces (2007/8-2024/25, = 200,601 starts in 3389 races) were used to examine initial speed (from barriers until the final 600 m), final-600 m speed, race distance (m), turf track condition score (TCS, 1-10), horse rating and carried weight (kg) using a general linear model. The patter...

Alterations in blood metabolites as biomarkers of fatigue and recovery in thoroughbred horses performing repeated bouts of high-intensity exercise. High-intensity exercise in horses resulting in fatigue requires a better understanding of biomarkers defining the condition such that protocols detailing the return to work can be established. This study examined blood metabolite profiles after multiple sessions of high-intensity exercise to define physiological exhaustion. Adult Thoroughbred geldings (n = 10) underwent a standardized exercise test (SET) on a high-speed treadmill, with BHB, BCAAs, alanine, lactate, and CK measurements at regular intervals up to 6 h post-SET. Before and 24 h post-SET gluteus medius muscle samples were t...
Physiological adaptations to 6 weeks of high-intensity interval and moderate-intensity continuous training in horses: A randomized crossover study. This study tested the hypothesis that 6 weeks of high-intensity interval training (HIIT) would induce greater physiological adaptations than moderate-intensity continuous training (MICT) in Thoroughbred horses. Seven untrained horses completed two distance-matched treadmill training protocols (three sessions per week) in a randomized crossover design, separated by a three-month washout: MICT (6 min at 70% ) and HIIT (6 × [30 s at 100% with 30 s at 30% ]). Incremental exercise tests were conducted at weeks 0, 3, and 6 to assess exercise performance and physiological responses. M...

A narrative review of factors influencing rider performance and horse welfare in equestrian activities. Equestrian sport is a unique multi-species discipline in which the performance of a horse-rider dyad depends on the harmonious interaction of two athletes with distinct biomechanics and needs. Although the sport contributes substantially to the global economy and is the only Olympic event involving two species, research on rider-centered factors has been fragmented. Current narrative review centered peer-reviewed evidence addressing three questions: (RQ1) how rider biomechanics and posture influence horse performance and welfare; (RQ2) what causes and consequences rider asymmetry has; and (RQ3...
Omic technology to monitoring resilience and adaptation to exercise and heat stress in endurance horses. In horses, heat exposure modulates the hypothalamic-pituitary-adrenal axis, autonomic nervous system, and hypothalamic-pituitary-thyroid axis to maintain body temperature and prevent excessive heat accumulation. However, during strenuous exercise under hot and humid conditions, heat production may exceed dissipation, leading to heat stress, anhidrosis, heat stroke, or brain damage. Unassigned: Incremental field standardized exercise tests (fSETs) provide a reliable approach to assess training and fitness levels. Six Arabian horses from Italia Endurance Stable and Academy were monitored during ...

We hypothesized that horse riders demonstrate better core stability performance. Methods: 75 people aged 15-30 (20 recreational horse riders, 20 sport horse riders and 35 non-horse ...
Maximal Lactate Steady State Prediction Using Two DMAX Methods in Horses Subjected to Treadmill-Graded Exercise Test. Maximal lactate steady state (MLSS) and its predictive thresholds, including the lactate threshold (LT), are widely used to estimate endurance capacity, prescribe training, and assess the effects of training. The human literature identified approximately twenty-five methods to predict the MLSS. This communication compares the concordance between the two D methods and the MLSS. Under laboratory conditions, ten teaching horses underwent a submaximal graded exercise test (GXT) on a treadmill to obtain their lactate-velocity curves (LVC). They performed three to five 30-min continuous running sess...
Defining the Heart Rate Zone Corresponding to the Lactate Threshold in Colombian Paso Horses. Colombian Paso horses (CPs) excel in gait competitions due to their endurance, speed, and precision, which demand a high level of cardiorespiratory fitness. However, their training regimes often lack scientific support, and few studies have linked physiological parameters to optimal training zones. This study aimed to estimate the aerobic lactate threshold (LTaer) using mathematical methods and to correlate it with heart rate (HR) zones and blood lactate. Eighteen CPs were evaluated and classified into trained (GT) and untrained (GD) groups. All animals underwent a field-based incremental exer...

Associations between maximum speed and locomotor parameter...
Morphometric changes in overweight horses following 10-week weight loss programs. Up to 70% of horses in domestic equine populations are overweight. Promotion of weight loss is an important component of limiting the detrimental co-morbidities associated with excess adipose tissue. The use of a body condition score (BCS) can help equine caregivers track their horse's weight-status. However, this single score doesn't reflect changes in individual adipose depots. The purpose of this study was to characterize morphometric changes (including 8 anatomic BCS measurements that make up the whole-BCS) in horses during 3 different weight-loss programs over 10 weeks. Methods: Thirty-tw...
Technologies for equine welfare and performance monitoring under field conditions – Where do we stand? The need for comprehensive equine welfare assessments has become particularly evident amid ongoing debates about the social licence to operate in equestrian sports. During exercise, multiple physiological systems, principally the cardiovascular, respiratory, muscular, thermoregulatory, endocrine, and locomotory systems, undergo complex adaptations. To monitor and determine equine welfare, an approach that focuses on the quantitative monitoring of both physiological and psychological parameters to determine and understand the impact of equestrian sports on horses is essential. Existing and emer...
Does Muscle Development of Sport Horses Using Water Treadmill Exercise as Part of a Long-Term Training Programme Differ from That of Horses Not Using Water Treadmill Exercise? Water treadmill (WT) exercise has become a popular tool for equine training and rehabilitation. However, few studies describe the long-term effects of WT exercise in low water on muscle development (MD). This study's objectives were to compare MD changes over a 40-week period in sport horses that regularly used WT in low water within training (Group WTH, = 55) and a control group that did not (control, = 28). Subjective MD assessments were undertaken using an adaptation of a previously published method at weeks 0, 20 and 40. For Group WTH, MD significantly increased in the neck, pelvis and h...

Unassigned: 40 race-fit Thoroughbred racehorses were used for 5 days in May 2024. Surface ECG recordings were obtained simultaneously from the FT and RM devices in horses swimming 63.65 m across a pool. Electrocardiograms were reviewed and artifacts corrected when necessary, and correlations were analyzed between the 2 devices for HR and HRV parameters. Descriptive statistics and Bland-Altm...
Horse Activity Participants’ Perceptions About Practices Undertaken at Activity Venues, and Horse Welfare and Wellbeing. Participation in horse-related activities frequently involves relocating horses from the home stable to an activity venue, which might require local, regional, or international travel. In these circumstances, horses are exposed to unfamiliar surroundings and experience changes to their daily routines, which could have negative welfare impacts. An online survey was conducted in 2021 to ask experienced horse sector participants about the horse management practices that they perceived worked well and provided for positive horse welfare when undertaken at venues. Qualitative analysis identified fo...
Colombian Criollo horses’ trot, trocha, and gallop are submaximal oxygen consumption gaits with unique locomotory-respiratory coupling. Colombian Criollo horses are bred for their smooth gaits that emphasize full collection and rapid footfall. The physiological demands of these gaits remain unknown. Our objective was to determine if oxygen consumption, ventilation, locomotor-respiratory coupling, and running economy differed between the trot or trocha and the gallop. Unassigned: 7 competition horses completed a controlled design standardized field test between January 10 and 20, 2025. Horses wore a cardiotachometer and ergospirometer to measure heart rate, oxygen consumption, and ventilation at the trot or trocha and the gallo...
