Polo ponies and horses are equines specifically trained and bred for the sport of polo, which is a team game played on horseback. These horses are selected for their agility, speed, and stamina, as these attributes are essential for the fast-paced and dynamic nature of polo matches. Polo ponies are typically smaller and more compact than other horse breeds, allowing for quick turns and bursts of speed. The training of polo ponies involves conditioning for endurance, responsiveness to rider cues, and the ability to perform sudden stops and changes in direction. This page compiles peer-reviewed research studies and scholarly articles that explore the breeding, training, performance, and welfare considerations of polo ponies and horses in the context of equestrian sports.
Ferraz GC, Soares OA, Foz NS, Pereira MC, Queiroz-Neto A.This study was designed to consider the complexity of the physical effort inherent to horses in polo competitions and the absence of reports in the literature on the effort, intensity and electrolyte changes resulting from a collective team training session aimed at preparing for a polo championship. Objective: To determine the effort and ion changes caused by an outdoor polo training match for a 25 goal handicap (elite) based on physiological variables including acid-base status (venous pH, PCO(2) and HCO(3)(-)), packed cell volume (PCV), haemoglobin (Hb), lactate, glucose, sodium, chloride a...
Tan H, Wilson AM.Manoeuverability is a key requirement for successful terrestrial locomotion, especially on variable terrain, and is a deciding factor in predator-prey interaction. Compared with straight-line running, bend running requires additional leg force to generate centripetal acceleration. In humans, this results in a reduction in maximum speed during bend running and a published model assuming maximum limb force as a constraint accurately predicts how much a sprinter must slow down on a bend given his maximum straight-line speed. In contrast, greyhounds do not slow down or change stride parameters dur...
Stanley RL, McCue ME, Valberg SJ, Mickelson JR, Mayhew IG, McGowan C, Hahn CN, Patterson-Kane JC, Piercy RJ.A glycogen synthase (GYS1) mutation has been described in horses with histopathological evidence of polysaccharide storage myopathy (PSSM) in the USA. It is unknown whether the same mutation is present in horses from the UK. Objective: To determine whether the GYS1 mutation occurs in UK horses with histopathological evidence of PSSM and exertional rhabdomyolysis. Objective: The R309H GYS1 mutation is present in a variety of UK horse breeds and that the mutation is commonly associated with exertional rhabdomyolysis. Methods: DNA was extracted from 47 muscle or blood samples from UK horses with ...
Vail JD.There is increasing evidence that regular mental and physical exercise can enhance overall health and functional abilities in older adults. This article describes how a vigorous program of playing polo can provide important mental and physical benefits-even for older adults. In the present context of health care reform, it is especially important for health care professionals to recognize the value of exercise as an useful, cost-effective intervention for enhancing mental and physical health and to explore ways to encourage their older clients to adopt an enjoyable exercise program.
McGowan CM, Posner RE, Christley RM.A questionnaire was used to determine the incidence of exertional rhabdomyolysis and the factors that might have contributed to its occurrence among 423 polo horses in 11 yards. The yards were selected at random, six of them with 111 horses, in north-eastern USA, and five with 312 horses in south-east England. During the 1999/2000 season the incidence of the condition was 7.3 per cent (9 per cent in the USA and 6.7 per cent in England). The incidence in mares was similar in the two countries, 8.4 per cent in the USA and 8.0 per cent in England, but the incidence in geldings in the USA (10 per ...
Costa-Paz M, Aponte-Tinao L, Muscolo DL.To assess prospectively the incidence, nature, and severity of injuries to polo riders competing in the 1996 Argentine High Polo season. Methods: Assessment, documentation, and provision of care for all injuries sustained during the 1996 season by one of the authors. Riders were also surveyed retrospectively for their previous polo injuries. Results: 34 riders took part in the study. Nine injuries were sustained prospectively and 55 injuries were reviewed retrospectively (64 total). The injuries were categorised as minor (10), moderate (13), and major (41). Twenty five (39%) injuries occurred ...
Marlin DJ, Allen JC.Knowledge of the competitive demands of different sports or activities is important for designing appropriate training programmes to ensure that animals reach a sufficient level of fitness to reduce the risk of overexertion and injury or illness and to achieve the best possible performance in relation to an individual's genetic potential. Whilst the physiological demands of many equestrian sports have been described, to the best of our knowledge the cardiovascular demands of polo have not. The aims of the present study were therefore to record heart rate during and after competitive polo games...
Wernery U, Nothelfer HB, Böhnel H, Collins WR.An acute outbreak of a C. perfringens Type C enterotoxemia in a polo club killed 8 polo ponies in less than 24 hours. Hay with a massive fungal contamination (Aspergillus and Fusarium sp.) is suspected to have triggered the enterotoxemia. Our cases show numerous similarities with the previously reported cases of EIC. However, acute toxic tubulonephrosis in the necropsied horses and longstanding elevation of AST and gamma GT-levels in survivors is unique in our cases.
Adeyefa CA.Serological evidence of Equine Herpes virus type 1 (EHV-1) activity in Polo horses in Nigeria is reported for the first time. Eighty-two percent of horses tested with known antigen had precipitating antibodies to EHV-1 while 43% of sera tested against antigen prepared from nasal discharges were positive suggesting that the virus was being excreted in the nasal discharges and probably acting as a source of infection for incontact animals as occurs in on-going acute infections. The result of this study indicates a high prevalence of EHV-1 activity among Polo horses in Nigeria and demonstrates th...
Adeyefa CA, Durojaiye OA.Serum samples obtained from 107 Polo horses showing clinical signs of viral respiratory disease were tested for precipitating antibodies to adenovirus by agar gel precipitation test and counter-immunoelectrophoresis method. The results obtained demonstrate serological evidence of adenovirus infection in Polo horses in Nigeria. The counter-immunoelectrophoresis method was observed to be about 3 times more sensitive than the agar gel precipitation test with 19.3 vs 64.5%. It could thus be used to screen a large number of serum samples within a short period.
Donaldson LL.In the United States, more than 75% of equine athletes are reported to suffer from exercise-related haemorrhage of the respiratory tract (Voynick and Sweeney, 1986; Sweeney et al., 1990). Fiberoptic endoscopy has traced the source of blood to beyond the bifurcation of the trachea. In 1981, the term exercise-induced pulmonary haemorrhage (EIPH) was introduced (Pascoe et al., 1981). Racehorses of all breeds, polo ponies and three-day event horses of mixed heritage, even foxhunters, may 'bleed' (Voynick and Sweeney, 1986; Pascoe et al., 1981; Sweeney and Soma, 1983; Hillidge, 1986). Any horse wor...
Lane JG, Lucke VM, Wright AI.Papillomatous lesions intruding into the laryngeal airway were identified in an imported polo pony during a routine neurological examination for partial quadriplegia. Histological examination established a diagnosis of laryngeal besnoitiosis but it is unlikely that the laryngeal parasitism was associated with the cerebellar neuropathy which was also present.
Voynick BT, Sweeney CR.Philippine polo and racing horses were examined for exercise-induced pulmonary hemorrhage after their competitive exercise. Exercise-induced pulmonary hemorrhage occurred in 11.1% of the polo horses and 64% of the racing horses. None of the horses had blood at the nostrils.
Craig L, Hintz HF, Soderholm LV, Shaw KL, Schryver HF.There have been several studies of biochemical changes in horses doing intense exercise such as Thoroughbred and Standardbred racehorses and in horses performing exercise over a long period of time such as endurance horses and three-day eventing horses, but we are not aware of studies with polo horses. Blood samples were taken from 18 polo horses at rest, immediately after playing 2 chukkers of indoor polo, and after a 15 minute rest period. Each horse was studied at 2 different games. The blood samples were analyzed for lactic acid, protein, sodium, potassium, chloride, calcium, phosphorus, H...
Saibene F, Cortili G, Gavazzi P, Sala A, Faina M, Sardella F.Blood lactate concentrations were determined in 16 horses (three Thoroughbreds, seven Standardbreds and six polo ponies) before and 5 mins after they galloped over distances of 200, 300 and 400 m at maximal speed. The highest net lactate concentration (delta Lamax) of 14 to 15 mmol/litre was attained by the polo ponies and the highest speed by the Thoroughbreds. The maximal rate of lactate production (delta Låmax) was about 35 mmol/litre X min for the polo ponies and 20 to 25 mmol/litre X min for the Standardbreds and the Thoroughbreds. Values for delta Lamax and delta Låmax were similar to ...
Aganga AO, Kwanashie GG, Belino ED.A serological survey of Toxoplasma antibodies was carried out amongst horses used for polo game in Nigeria using the indirect haemagglutination test (IHA). A total of 70 horses from Kaduna, Kano and Jos that were assembled in Zaria for the annual national tournament were sampled. 26 (37.1%) of these were seropositive to T. gondii with the highest serological titre at 1:256. Out of the 52 local breeds, 20 (38.5%) were seropositive while of the 18 Argentine breeds, 6 (33.0%) were seropositive. No significant difference was found amongst the breeds. With the increasing interest in the game of pol...
Irwin DH.Thirty seven intra-articular injections, each 2 ml sodium hyaluronate were made into 21 arthritic joints in 15 racing Thoroughbreds and one part-bred polo pony. One joint failed to improve at all, 16 became sound with one injection, 4 became sound with 2 injections, and 11 joints showed various degrees of response. Eleven of 14 horses became sound for flat racing. Discussion relates to the technique of using sodium hyaluronate, some clinical and pathological aspects of traumatic arthritis, joint lubrication and a brief review of some properties of sodium hyaluronate which have a bearing on art...
Pietrani M, Losinno L, Cuervo Arango J.In the present study, 2.228 cycles of 180 Polo Argentino donor mares from an embryo transfer program in Argentina were examined to evaluate the effects of: (1) Interval from Prostaglandin F2alpha analog treatment to ovulation (ITO) on embryo recovery rate (ERR); (2) ITO on number of embryos per flushing (EPF); (3) ITO on multiple ovulation (MO) rate; (4) ITO from donor mare on pregnancy rate (PR) in recipient mares. Mares were inseminated with fresh semen from 31 fertile stallions in the induced estrus. Embryo flushing was performed 7-8 days postovulation. Following embryo flushing, donor mar...
Kent E, Coleman S, Bruemmer J, Casagrande RR, Levihn C, Romo G, Herkelman K, Hess T.Antioxidant supplementation decreases postexercise oxidative stress but could also decrease muscle protein synthesis. This study compared the effects of three diets: low antioxidant (control, CON), high antioxidant (AO), and branched-chain amino acid high antioxidant (BCAO) supplementation on postexercise protein synthesis and oxidative stress. We hypothesized that supplementing antioxidants with branched-chain amino acids(BCAA) would reduce oxidative stress without hindering muscle protein synthesis. Eighteen mixed-breed polo horses (11 mares and 7 geldings, with age range between 5 and 18 ye...

Carvalho Seabra J, Hess T, Martinez do Vale M, Spercoski KM, Brooks R, Dittrich JR.Free choice forage could be the best option regarding horses' welfare but can lead to increased body weight (BW), and waste of hay. Automatic box feeders (BF) and slow feeders (SF) decrease food waste, but it is unknown how these affect the horses' time-budget (TB). This study compared the effects of feeding free choice hay (FC), to a SF and an automated BF on the horses' cortisol circadian rhythm (CCR) and behavior by 24-hours continuous behavioral sampling (CBS). The study was designed as a 3 × 3 Latin square design with 15 polo horses divided into 3 groups, for 15 days on each treatment....
Martinez MM, Costa M, Corva PM.Argentine Polo (AP) is a young horse breed with a fast expansion because of an open registry policy and the application of assisted reproduction technologies. In the last years, AP showed a remarkable progress associated with the use of embryo transfer technology and intensive selection based on sport performance. However, these practices could have affected the genetic variability of the breed. To monitor these potential changes, a parentage panel of 11-15 microsatellites was investigated for changes in allele frequencies, heterozygosity, and exclusion probability over a 16 year period. Frequ...
Oliver GD, Gilmer GG, Barfield JW, Brittain AR.Although polo is a well-known equestrian sport, it is fundamentally misunderstood. The purpose of this study was to examine trunk and upper extremity kinematics and segmental velocities during the offside forehand polo swing between male and female athletes. Ten female and 17 male professional polo athletes volunteered. An electromagnetic tracking system collected kinematic data at 100 Hz while participants performed three offside forehand polo swings from a stationary wooden horse. One-way ANOVAs revealed statistically significant differences (<0.05) in all kinematic variables and segmenta...

Moorman VJ, Bass L, King MR.To determine the effects of 3 α2-adrenergic receptor agonists (α2-ARAs), alone or in combination with butorphanol tartrate, on objective measurements of lameness in horses. Methods: 17 adult polo horses with naturally occurring forelimb or hind limb lameness (or both). Methods: In a crossover design, each horse received each protocol (saline [0.09% NaCl] solution [2 mL, IV] or xylazine hydrochloride [0.33 mg/kg, IV], detomidine hydrochloride [0.007 mg/kg, IV], or romifidine hydrochloride [0.033 mg/kg, IV] alone or in combination with butorphanol [0.007 mg/kg, IV]) in random order, with a was...
Azcona F, Karlau A, Trigo P, Molina A, Demyda-Peyrás S.The Polo Argentino (PA) horse is a recognized breed, developed originally by mixing crossbred and Thoroughbred (TB) horses to play polo. Early PA selection is difficult due to unreliable performance estimations. This study investigated the usefulness of genomic markers previously linked to morphological and functional traits as a tool for the early selection of PA. To this, we genotyped 520 PA and 30 TB horses using the Equine GGPArray (Illumina, n=71,778 SNPs). Analyses included a genetic characterization of six genetic markers associated with behavioral (DRD4), muscular development (MSTN), a...

Best R.The external work, as measured by global positioning systems, undertaken by Polo ponies during tournament play has been well-described across Polo of varying levels in both Open and Women's Polo. However, the variability within these data have not been thoroughly examined. Understanding the variability within these data between players (within-tournament variability) and between tournaments allows a deeper understanding of expected Polo performance and can inform coaching and tactical decisions, as well as aid in longitudinal horse development and comparison to other equestrian disciplines. Th...

Nolen-Walston RD, Moore CM, Barr CA, Tomlinson JE, Boston RC, Soma LR.To determine the anabolic and lipolytic effects of a low dosage of clenbuterol administered orally in working and nonworking equids. Methods: 8 nonworking horses and 47 polo ponies in active training. Methods: Each polo pony continued training and received either clenbuterol (0.8 μg/kg) or an equal volume of corn syrup (placebo) orally twice daily for 21 days, and then was evaluated for another 21-day period. Nonworking horses received clenbuterol or placebo at the same dosage for 21 days in a crossover trial (2 treatments/horse). For working and nonworking horses, percentage body fat (PBF) w...

Schumacher A, Gehlen H.This literature review analyzes the historical development of polo, its organizational structure, the course of the game, as well as the breeding, rearing, and training practices of polo horses. Frequently occurring ailments, such as musculoskeletal injuries, respiratory diseases, and internal illnesses, are highlighted. Lameness is a major problem, with injuries to the superficial digital flexor tendon being the most common cause. Other notable diseases include exercise-induced pulmonary hemorrhage (EIPH), myositis, rhabdomyolysis, and equine infectious anemia (EIA). To ensure the welfare of ...
Ken-Dror G, Chua V, Sharma P.To determine the frequency of traumatic injuries in polo players in England. Methods: The survey included data on body location and reason for injury derived from accident reports using a retrospective cohort design from 26 participating English polo clubs between the years 2018 and 2024. Results: The study population included injuries in 236 polo players. The most common injury site was the limb (arm, hand, leg, wrist, shoulder) 47.9% (95% CI: 41.4-54.5), and face or head 38.6% (95% CI: 32.3-45.1), of which 12.1% (95% CI: 6.2-20.6) affected the eyes. The most common reason to require hospital...
