Topic:Jockeys
The relationship between jockeys and horses is a dynamic and complex aspect of equine sports, involving both human and animal athletes. Jockeys are professional riders who guide horses in competitive racing events, requiring a deep understanding of equine behavior, physiology, and racing strategy. The interaction between jockeys and horses is critical for performance, as it involves communication, trust, and precise coordination. Various factors such as weight management, riding techniques, and safety protocols are integral to this partnership. This page compiles peer-reviewed research studies and scholarly articles that explore the biomechanics of jockey riding, the impact of jockey weight on horse performance, and the psychological and physiological interactions between jockeys and horses in the context of competitive racing.
The association between jockey experience and race-day falls in flat racing in Australia. Apprentice thoroughbred racing jockeys have a higher fall rate than their more experienced counterparts. The authors describe rates of occurrence and investigate risk factors for falls among less-experienced thoroughbred flat racing jockeys in Australia who commenced their race riding career between August 2002 and July 2009. Methods: Data on race-day falls were extracted from stewards' reports. Denominator data were provided by Racing Information Services Australia on races conducted in Australia. HRs were estimated using time-to-event (survival analysis) methods. Results: Factors found to be...
Whip use by jockeys in a sample of Australian Thoroughbred races–an observational study. The use of whips by jockeys is an issue. The current study viewed opportunistic high-speed footage of 15 race finishes frame-by-frame to examine the outcomes of arm and wrist actions (n = 350) on 40 horses viewed from the left of the field. Any actions fully or partially obscured by infrastructure or other horses were removed from the database, leaving a total of 104 non-contact sweeps and 134 strikes. For all instances of arm actions that resulted in fully visible whip strikes behind the saddle (n = 109), the outcomes noted were area struck, percentage of unpadded section making conta...
Risk factors for race-associated sudden death in Thoroughbred racehorses in the UK (2000-2007). Sudden death adversely affects racehorse welfare, jockey safety and the public perception of horseracing. Objective: To describe the risk of racing-associated sudden death in Thoroughbred racehorses in the UK from 2000 to 2007, to identify whether there were risk factors uniquely associated with sudden death and to improve the understanding of the pathogenesis of racing-associated sudden death by identification of risk factors for such cases. Methods: A sudden death was defined as an acute collapse and death, in an apparently healthy Thoroughbred racehorse, during or immediately after racing, ...
The association of various speed indices to training responses in Thoroughbred flat racehorses measured with a global positioning and heart rate monitoring system. Fitness assessment can be challenging. The use of global positioning systems (GPS) with heart rate (HR) monitors has been promising; however, evaluation of speed parameters during training has not been reported. Objective: To evaluate speed indices during training in Thoroughbreds using a GPS-HR monitor. Methods: Thoroughbreds (n = 102) were assessed during training with data collected each work day (WD; sprinting). Speed indices evaluated included maximal velocity (V(max)), duration at V(max) (V(maxt)), acceleration rate (m/s(2)) from 800 m to V(max) (Acc800-V(max)), the distance (m) 6 (V(max...
Saddle pressure patterns of three different training saddles (normal tree, flexible tree, treeless) in Thoroughbred racehorses at trot and gallop. To a large extent the success of a racehorse depends on effective and health preserving training methods. An important issue is the prevention of back pain. The influence of different types of training saddles (normal tree: S(A), treeless: S(B), flexible tree: S(C)) on the saddle pressure patterns in racehorses have not previously been investigated. It is commonly assumed that S(A) limits the motion of the back especially in the lower thoracic region during gallop. Objective: S(A) produces higher pressures in the caudal part of the saddle at trot (rising trot), canter and gallop (both in a joc...
Nutritional, lifestyle, and weight control practices of professional jockeys. In this study, we describe diet and lifestyle practices of professional jockeys. Participants completed a 59-item nutrition, lifestyle, and health questionnaire (n = 21) and a 7-day estimated food diary (n = 18). Acute weight loss strategies included the use of saunas (86%), exercising to induce sweating (81%), and restricted energy intake (71%). Of the smokers (38%), 56% used smoking to control weight. Most (86%) jockeys reported attaining a 2-kg weight loss for racing (if required) 24-48 h before or on the designated race-day. Mean daily energy intake (1803 ± 564 kcal) was low and appeared ...
An investigation of racing performance and whip use by jockeys in thoroughbred races. Concerns have been expressed concerning animal-welfare issues associated with whip use during Thoroughbred races. However, there have been no studies of relationships between performance and use of whips in Thoroughbred racing. Our aim was to describe whip use and the horses' performance during races, and to investigate associations between whip use and racing performance. Under the Australian Racing Board (ARB) rules, only horses that are in contention can be whipped, so we expected that whippings would be associated with superior performance, and those superior performances would be explaine...
Predictors of race-day jockey falls in jumps racing in Australia. Thoroughbred jumps racing jockeys have a fall rate greater than their flat racing counterparts. Previous studies have focused on factors that contribute to falls by horses but, to date, there has not been a study of risk factors for falls to jockeys in jumps races. Data on race-day falls were extracted from stipendiary stewards reports lodged with Principal Racing Authorities following each race meeting. Denominator data were provided by Racing Information Services Australia on races conducted from August 2002 until July 2009. Univariable and multivariable analyses, estimating incidence rate r...
Borna disease virus antibody and RNA from peripheral blood mononuclear cells of race horses and jockeys in Korea. During the last two decades, Borna disease virus (BDV) has received much attention as a possible zoonotic agent, particularly as a cause of psychiatric disease. Although several studies have shown that BDV is present in Asia, BDV has not been detected in Korea. This study was designed to further investigate the presence of BDV infection in Korea. Methods: Blood samples were taken from 39 race horses and 48 jockeys. Antibody to BDV was detected by indirect immunofluorescence antibody test and RNA of BDV by real time reverse transcriptase PCR (rRT-PCR). Results: No evidence of BDV was detected i...
Nutrition assessment of horse-racing athletes. Athletes involved in horse racing face weight restrictions like wrestlers and dancers; however, the literature is sparse pertaining to nutritional habits of jockeys. The practice of "making weight" causes these athletes to engage in potentially unhealthy practices. A gap in nutritionally sound practices and methods used by jockeys was identified and a desire for nutrition education was expressed to Cooperative Extension of Delaware by representatives of the riders at Delaware Park Race Track. Nutrition assessment was done using the Nutrition Care Process. Twenty jockeys were interviewed using ...
Finite element modelling of equestrian helmet impacts exposes the need to address rotational kinematics in future helmet designs. Jockey head injuries, especially concussions, are common in horse racing. Current helmets do help to reduce the severity and incidences of head injury, but the high concussion incidence rates suggest that there may be scope to improve the performance of equestrian helmets. Finite element simulations in ABAQUS/Explicit were used to model a realistic helmet model during standard helmeted rigid headform impacts and helmeted head model University College Dublin Brain Trauma Model (UCDBTM) impacts. Current helmet standards for impact determine helmet performance based solely on linear acceleration....
Predictors of race-day jockey falls in flat racing in Australia. Riding thoroughbred racehorses is a hazardous occupation. In this study, we investigated risk factors associated with falls by licensed thoroughbred racing jockeys participating in flat races conducted in Australia. Methods: Data on race-day falls were extracted from stewards' reports. Denominator data were provided by Racing Information Services Australia on races conducted in Australia from August 2002 until July 2006. Incidence rate ratios (IRRs) were estimated using Poisson regression. Analyses were stratified by race grade (maiden, class, open/restricted). Results: In multivariable analys...
Modern riding style improves horse racing times. When animals carry loads, there is a proportionate increase in metabolic cost, and in humans this increase in cost is reduced when the load is elastically coupled to the load bearer. Major horse race times and records improved by 5 to 7% around 1900 when jockeys adopted a crouched posture. We show that jockeys move to isolate themselves from the movement of their mount. This would be difficult or impossible with a seated or upright, straight-legged posture. This isolation means that the horse supports the jockey's body weight but does not have to move the jockey through each cyclical stride pa...
Fall and injury incidence rates of jockeys while racing in Ireland, France and Britain. This article presents and analyses injury incidence rates for amateur and professional racing jockeys in Ireland, France and Britain by means of a retrospective study and review of published data. Amateur jump racing was seen to have the highest fall risk in these three countries (between 115 and 140 falls/1000 rides). Jump racing also had the highest rates of injury/ride amongst both amateur and professional jockeys. Flat racing, however, had the highest rates of injuries/fall (34-44%). Of all the injuries in both jump and flat racing populations of amateur and professional jockeys, 15% were ...
Body mass index and serum gamma-glutamyltransferase level as risk factors for injuries related to professional horse racing: a prospective study. Prevention of horse-related injuries is considered difficult because horse behavior is unpredictable. Therefore, risk factors for injuries related to professional horse racing need to be investigated. We conducted a study to determine whether body mass index (BMI) and gamma-glutamyltransferase (GGT) levels are associated with professional horse racing-related injuries. Methods: A baseline healthy survey of 546 male grooms and exercise riders aged 40-70 yr working at Miho Training Center, the largest racing-horse training facility in Japan, was performed in May 2003. A total of 93 occupational ...
The incidence of race-day jockey falls in Australia, 2002-2006. To describe rates of occurrence of falls, injuries and fatalities to horse-racing jockeys in Australia. Methods: Retrospective analysis of data on race-day falls from stewards' reports provided by the Principal Racing Authority of each state and territory of Australia, August 2002 - July 2006. Methods: Fall, injury and fatality incidence rates; comparison with overseas rates. Results: There were 3360 jockey falls from 748 367 rides. Falls occurred at a rate of 0.42 per 100 rides in flat races and 5.26 per 100 rides in jumps races. In flat racing, 54.6% (1694/3101) of falls occurred before the ...
Psychological effects of rapid weight loss and attitudes towards eating among professional jockeys. We examined the psychological effects of rapid weight loss among a sample of 41 professional jockeys (mean age 30.9 years, s = 7.0). Participants completed the Brunel Mood Scale (BRUMS) and the Eating Attitudes Test-26 (EAT-26) to establish the relationships between rapid weight loss, mood, and attitudes towards eating. These instruments were administered on three occasions: at the jockeys' minimal weight (achieved through rapid weight loss), their optimal riding weight (when they were not excessively restricting their weight and felt healthy), and their relaxed weight (when there were no fort...
Payments to injured professional jockeys in British horse racing (1996-2006). To determine the direct and indirect cost of injuries in professional jockeys as a result of race riding. Methods: Cohort study. Methods: Professional horse racing. Methods: Professional jockeys in the UK registered with the Jockey Club. Methods: Payouts under the Professional Riders Insurance Scheme (PRIS) for injuries sustained by professional jockeys, which were recorded by the Jockey Club injury database between 1996 and 2006 inclusive. Results: In the 11-year period of the study, there were 1328 injuries that resulted in jockeys missing a total of 71,509 days of racing, and as a result PR...
Acute training in racing horses at two different levels of effort: A haemorheological analysis. During acute exercise several significant cardiovascular alterations take place, along with possible physiopathological consequences, such as Exercise Inducted Pulmonary Haemorrhage (EIPH). Given the relevance of blood rheology in the determination of flow resistance and its supposed participation in the stated events, the present paper focuses on the analysis of modifications in haematocrit, blood viscosity and erythrocyte deformability in Thoroughbred horses caused by two different levels of effort (6 to 9 m/s and 13 to 16 m/s), in the same track they train in and with their own jockeys. The...
Career-ending injuries to professional jockeys in British horse racing (1991-2005). It has been previously shown that professional jump and flat racing jockeys suffer a high incidence of injury as a consequence of their profession. This paper specifically examines career-ending injuries to professional jockeys in Great Britain. Objective: To investigate career-ending injuries in professional jockeys. Methods: Analysis of prospectively collected injury database on professional jockeys. Results: The majority of injuries in this study occurred to the head, shoulder or torso. Fractures were the most common type of injury that led to a decision to end a career, followed by neurolo...
Injuries in amateur horse racing (point to point racing) in Great Britain and Ireland during 1993-2006. To provide a breakdown of injury incidence from amateur jump racing (also known as point to point racing) in Great Britain and Ireland during 1993-2006 and to compare the injury epidemiology with professional horse racing in Great Britain, Ireland and France. Methods: Retrospective review. Methods: Great Britain and Ireland. Methods: Amateur jockeys. Methods: Injury rates. Results: Injury data suggest that point to point racing is more dangerous from an injury point of view than professional jump racing, which has previously been shown to be more dangerous than flat racing. Amateur jockeys hav...
Five year analysis of Jockey Club horse-related injuries presenting to a trauma centre in Hong Kong. Professional horse riding-related injuries have not been studied before in Hong Kong, although horse racing takes place very regularly in the territory. In addition, the equestrian events of the 2008 Beijing Olympic Games will come to Hong Kong. This study analysed the pattern of horse-related injury among patients who presented to a trauma centre in a teaching hospital in Hong Kong. Methods: Information from the trauma centre database was analysed retrospectively. The database includes trauma patients who had sustained potentially severe injuries that warranted initial assessment and resuscit...
Limb fractures more common in French than British jockeys. French jockeys suffer more severe injuries when they fall off their horses than their British counterparts. While it has been shown that jockeys suffer high rates of fatal and non-fatal injuries, little is known about differences in injury rates between countries. To investigate this, researchers from Australia, France and the UK used prospectively collected data on the rates of fatal and non-fatal injuries in flat and jump jockeys in France and compared them with data from the UK.
Ethnoveterinary medicines used for horses in Trinidad and in British Columbia, Canada. This paper investigates the commonalities in ethnoveterinary medicine used for horses between Trinidad (West Indies) and British Columbia (Canada). These research areas are part of a common market in pharmaceuticals and are both involved in the North American racing circuit. There has been very little research conducted on medicinal plants used for horses although their use is widespread. The data on ethnoveterinary medicines used for horses was obtained through key informant interviews with horse owners, trainers, breeders, jockeys, grooms and animal care specialists in two research areas: Tr...
No borna disease virus-specific RNA detected in blood of race horses and jockeys. Borna disease virus (BDV) predominantly infects horses and sheep, causing a broad range of behavioural disorders. It is controversial whether BDV infects humans and causes psychiatric disorders. Objective: We searched for BDV-derived nucleic acids in blood of race horses and jockeys riding the horses. Methods: We assayed for the BDV genome in RNA extracted from peripheral blood mononuclear cells (PBMC) of 39 race horses and 48 jockeys. Two polymerase chain reaction protocols [one-tube reverse transcription-polymerase chain reaction (RT-PCR) and two-step RT-PCR] were used to assay BDV p24 and p...
An analysis of injuries resulting from professional horse racing in France during 1991-2001: a comparison with injuries resulting from professional horse racing in Great Britain during 1992-2001. It has been previously shown that professional jockeys suffer high rates of fatal and non-fatal injuries in the pursuit of their occupation. Little is known, however, about differences in injury rates between countries. Objective: To determine the rate of fatal and non-fatal injuries in flat and jump jockeys in France and to compare the injury rates with those in Great Britain and Ireland Method: Prospectively collected injury data on professional jockeys were used as the basis of the analysis. Results: Limb fractures occur four times more often in both flat and jump racing in France than in G...
Phenotypic and genetic parameter estimates for racing traits of Arabian horses in Turkey. The racing records for Arabian horses used in the study were obtained from the Turkish Jockey Club. The traits used in the study were racing time, best racing time, rank, annual earnings, earnings per start, log annual earnings and log earnings per start. Genetic parameters were estimated by the restricted maximum likelihood (REML) procedure using the DFREML program. The effects of age, sex and origin of horse were significant for each trait. The effect of year was significant on time and earning traits, but not rank. The effect of month on time traits was also significant. Heritability estima...
Risk factors for fatal lateral condylar fracture of the third metacarpus/metatarsus in UK racing. Lateral condylar fractures of the third metacarpus/metatarsus are the most common cause of equine fatality on UK racecourses. Identification of risk factors for such injuries and the subsequent implementation of intervention strategies could significantly reduce the total number of racecourse fatalities. Objective: To identify horse-, race- and course-level risk factors for fatal lateral condylar fracture in Thoroughbreds on UK racecourses. Methods: Case-control study designs were used. Case horses were defined as those that were subjected to euthanasia having sustained an irreparable lateral ...
A prospective cohort study to investigate risk factors for horse falls in UK hurdle and steeplechase racing. Equine fatalities during racing continue to be a major welfare concern and falls at fences are responsible for a proportion of all equine fatalities recorded on racecourses. Objective: To identify and quantify risk factors for horse falls in National Hunt (NH) racing and to report the frequency of falling and falling-associated fatalities. Methods: A prospective cohort study was conducted on 2879 horse starts in hurdle and steeplechase races on 6 UK racecourses. Any horse that suffered a fall at a steeplechase or hurdle fence during the race was defined as a case. Data were obtained by intervi...
Case-control investigation of the factors affecting the risk of horses falling during steeplechase racing in the UK. A concurrent case-control study of 12 UK racecourses was made between March 1, 2000, and August 31, 2001, to identify and quantify the factors associated with the risk of horses falling in steeplechase races. Cases were defined as a jumping effort at a steeplechase fence that resulted in a fall and controls were defined as a successful jumping effort over any steeplechase fence at any of the 12 racecourses within 14 days before or after the case fall. Information on the horse, the jockey and the race were collected and all the fences on all the courses were surveyed. Conditional logistic regre...
