Two experiments were conducted to evaluate the effects of various approaches to training equestrian skills. The purpose of Experiment 1 was to compare an instructional video(s), in combination with verbal instruction, to verbal instruction alone on the percentage of horseback riding and safety errors made among beginner trail riders. An analysis of the overall percentage of steps completed independently revealed significant differences between instructional conditions that favored the use of video. Experiment 2 involved more experienced riders and more sophisticated equitation skills. Specifically, it examined whether a training package would decrease the percentage of jumping equitation errors among riders training in the sport of eventing. Using a multiple baseline across participants design, a training package was evaluated which entailed written feedback and video footage of the lesson from the trainer's point of view in addition to standard instruction. The findings of this study are inconclusive. The overall performance of riders through a six jump course was highly variable from week to week, regardless of the type of instruction utilized during lessons. Although several jumping equitation skills were never problematic for riders, no other skills routinely improved. Limitations and future studies are discussed.

Introduktion: Ridsporten är Sveriges näst största ungdomsidrott och totalt Sveriges åttonde största sport. Ridsport som helhet innefattar en hög skaderisk och är den sport med tredje högsta antal rapporterade skador efter fotboll och ishockey. Inom ridsport är de olympiska grenarna hoppning, dressyr och fälttävlan. Syfte: Syftet med studien var att kartlägga skadeprevalensen hos ryttare på elit- och nationell nivå inom hoppning, dressyr och fälttävlan. Metod: För att kunna besvara syftet genomfördes en kartläggning i egenskap av en retrospektiv kvantitativ observationsstudie. Studien baserades på en enkät som bestod av två delar, Oslo Sport Trauma Research Center Overuse Injury Questionnaire samt egenkonstruerade följdfrågor med inriktning ridsport, sysselsättning, annan sport samt träning. Resultat: Enkäten besvarades av 123 ryttare. Totalt rapporterade 101 ryttare (82 %) en/ flera skador. Det vanligaste skadeområdet var ländryggen för både akuta- och långvariga skador, med 59 ryttare (33 %) och 36 ryttare (24 %). Det noterades en högre risk att drabbas av långvariga skador om ryttaren tävlade inom hoppning (p=0,033) samt det noterades även en högre risk att drabbas av ländryggssmärta om ryttaren tävlade inom dressyr (p=0,034). Det fanns inga signifikanta skillnader mellan skadeprevalensen och träning eller annan sysselsättning utöver ridsporten. Slutsats: Sammanfattningsvis är det vanligt med skador bland ryttare på elit- och nationell nivå och skadeprevalensen skiljer sig inte i en mätbar grad mellan tävlingsnivåerna. / Introduction: Equestrianism is Sweden’s second largest sport in youths and Sweden's eighth largest sport overall. Equestrianism involves a high risk of injury and is the sport with the third highest number of reported injuries after football and ice hockey. In equestrian sports, the Olympic disciplines are show jumping, dressage and eventing. Purpose: The purpose of the study was to map the injury prevalence of riders at elite and national level in show jumping, dressage, and eventing. Method: To answer the purpose, a survey was conducted as a retrospective quantitative observational study. The study was based on a questionnaire that consisted of two parts, the Oslo Sport Trauma Research Center Overuse Injury Questionnaire and self-constructed follow-up questions focusing on equestrian sports, employment, other sports, and exercise. Results: The survey was answered by 123 riders. A total of 101 equestrians (82 %) reported one/more injuries. The most common injury area was the lumbar spine in both acute and long-term injuries, with 59 riders (33 %) and 36 riders (24 %). A higher risk of long-term injury was noted if the rider competed in show jumping (p=0,033). A higher risk of low back pain was also noted if the rider competed in dressage (p=0,034). No correlation was noted between the prevalence of injury and training or other employment in addition to equestrian sport. Conclusion: In conclusion, injuries are common among elite and national level riders and the prevalence of injuries does not differ to a measurable degree between competition levels.

Rotational falls, or somersault falls, have led to serious and fatal injuries during the cross-country phase of Eventing competitions. Research to improve the safety of the sport began in 2000 after five fatal injuries occurred in the 1999 Eventing season. These efforts led to safety devices such as air jackets, improved helmets, and frangible/deformable fences. The focus of this thesis is to develop a more complete understanding of the horse-fence interaction as the approach motion transitions to a rotational fall. To achieve this, a large distribution of inertial properties was compiled through the development of a cylinder-based inertia approximation and a citizen science effort to gather equine geometrical measurements through a survey distributed by the United States Eventing Association (USEA). Furthermore, fundamental kinematic properties of the horse and rider were gathered from the literature. These distributions were used to conduct a Monte Carlo analysis to examine if the approach conditions of the horse and rider would result in a transition to a rotational fall upon horse-fence contact. Through the analysis the sensitivity of the main control parameters was explored to determine the dominant variables in the transition.

Todos os equinos que participam de competições de alto rendimento devem ser submetidos a um plano de treinamento estruturado baseado nas suas condições fisiológicas. Este deve ter como finalidade desenvolver um atleta que expresse o máximo do seu potencial, preservando o equino para que ele tenha uma vida desportiva mais duradoura possível e com o menor número de lesões. O treinamento físico promove alterações fisiológicas nos sistemas energético, aeróbico e anaeróbico, cardiovascular e respiratório, endócrino e musculoesquelético. O presente estudo teve como objetivos avaliar o metabolismo de equinos destinados à modalidade de Concurso Completo de Equitação (CCE) de uso militar, por um protocolo de treinamento intervalado, utilizando testes a campo, através da frequência cardíaca, respiratória e bioquímica sanguínea (Lactato, Glicose, Creatina Quinase, Lactato Desigrogenase e Aspartato Aminotransferase). Os equinos destinados à equipe de CCE foram submetidos primeiramente a três dias de teste (Etapa 1) com intervalo de quatro dias de descanso entre cada teste, após participaram de um programa de treinamento intervalado por três dias semanais durante seis semanas consecutivas e novamente foram submetidos aos mesmos testes realizados no inicio do programa (Etapa 2) Os testes consistiam em Teste de Velocidade Incremental (TVI) em cinco estágios de velocidades crescentes (240, 320, 400, 480 e 560 m/min); Teste de Salto Incremental (TSI) realizado em três estágios de altura crescente (40, 55 e 70 cm) e Percurso de Salto (PS) contendo 13 esforços em uma velocidade de 325m/min. No TVI foi encontrado aumento da Frequência Cardíaca (FC) em todos estágios de acordo com aumento de velocidade. Os valores de FC da Etapa 1 foram inferiores ao da Etapa 2. Obtivemos diferença significativa nas velocidades 240m/min; 320m/min; 480m/min e 10 min/Ap. A FR dos animais foi superior na Etapa 1 comparada à Etapa 2. A diminuição dessa variável se mostrou significativa em todas velocidades. O nível de lactato plasmático não teve diferença significativa comparando as duas etapas. Os valores de glicose, durante o teste, mostraram diferença significativa somente na velocidade de 240 m/min da Etapa 2 em comparação com a Etapa 1. A mensuração das enzimas musculares CK, AST e LDH mostraram, em quase totalidade, diminuição significativa nas velocidades da Etapa 2 comparadas a Etapa 1. Na velocidade de 560 m/min e 10min/Ap, Etapa 2, o nível de CK sanguíneo não mostrou diminuição significativa, nesta mesma velocidade não houve decréscimo significativo no valor de AST. Durante o TSI a frequência cardíaca mostrou aumento significativo nas alturas 55 e 70 cm A frequência respiratória mostrou uma diminuição significativa nas duas últimas voltas, 55 e 70cm, e nos 10min após exercício da Etapa 2 comparado a Etapa 1. Os valores de Lactato e glicose não distinguiram estatisticamente com algum nível de significância comparando as duas etapas. A enzima CK não teve diferença significativa entre as duas etapas em contrapartida a LDH mostrou diminuição em todos valores das mensurações da Etapa 2 comparado a Etapa 1. Os valores de AST diminuíram com significância aos 55cm e nos 10 min após exercício da Etapa 2. No PS a frequência cardíaca no não teve variação na comparação entre as duas etapas. A frequência respiratória teve uma taxa de recuperação com diminuição significativa na Etapa 2. Os valores de lactato não aumentaram durante o percurso de salto na Etapa 2; os valores de glicose diminuíram durante o percurso, mas não mostraram variações significativas em nenhuma das etapas. As enzimas musculares CK e AST tiveram um aumento significativo nos 10 min/Ap durante a Etapa 2 comparado a Etapa 1. Os três testes demonstraram um efeito positivo na avaliação do condicionamento dos equinos destinados ao CCE. Se este efeito pode ser maximizado aumentando a intensidade, frequência ou período de treinamento intervalado, pesquisas adicionais são recomendadas. / All horses that participate in high level competitions should be submitted to a training protocol based on their own physiological conditions. Its aim must be to develop an athlete able to achieve its maximum potential, preserving the horse in order to permit the longest sportive life as possible and with the minimum of injuries. The physical training promotes physiological changes in aerobic and anaerobic energetic systems, cardiac, respiratory, endocrine and muscleskeletal systems. This study’s objective is to evaluate the athletic metabolism of eventing horses, using an interval training protocol. Field tests observing heart rate, respiratory rate and blood biochemistry (Lactate, Glucose, Kinase Creatine, Dehydrogenase Lactate and Aminotransferase) were used. The eventing team’s horses were submitted, firstly, to three tests (Phase 1), with a four days rest between each test. Then, after accomplishing a six week interval training protocol, a new sequence of tests were performed (Phase 2), repeating exactly those performed on Phase 1. The tests were: Incremental Speed Test in five raising speed stages (240, 320, 400, 480 and 560 m/min); Incremental Jumping Test in three increasing heights (40, 55 and 70cm); and Show Jumping Course Test with 13 fences and 380m/min speed. In the IST a heart rate increment was found in all stages according to the speed raising. The heart rate numbers on Phase 1 were lower than in Phase 2. Significant difference was found in speeds 240, 320 and 480m/min, and also 10 minutes after the last stage. The animals´ respiratory rate in Phase 1 was higher than in Phase 2. The lowering in this parameter was significant at all speed stages Plasma lactate levels showed no significant difference between the two Phases. Glucose numbers showed significant difference between Phase 1 and 2 only in the 240m/min speed stage. The measurement of CK, AST and LDH enzymes showed, in almost all tests, significant decreasing numbers in Phase 2 compared to Phase 1. In 560m/min speed and 10’ after, at Phase 2, Blood CK and AST levels showed no significant decrease. During IJT the heart rate numbers increased significantly in 55cm and 70cm heights. Respiratory rates decreased significantly in 55cm and 70cm heights and also 10’ after, comparing Phase 2 to Phase 1. Glucose and Lactate values had no significant statistic difference between the two Phases. CK enzyme showed no significant difference between the two Phases, although LDH showed decreasing measurement values in Phase 2 when compared to Phase 1. AST values decreased significantly in 55cm, 70cm and 10’after at Phase 2. In SJCT the heart rate had no variation comparing the two Phases. Respiratory rate showed significant decreasing in recovery rate on Phase 2. Lactate values did not increase during SJCT on Phase two; Glucose decreased during the SJCT, but did not show significant variation in any of the two Phases. CK and AST muscle enzymes increased significantly in 10’after at Phase 2 when compared to Phase 1. All three tests have a positive effect on the physical fitness level of eventing horses. Whether this effect can be maximized by increasing intensity, frequency or interval training period, further research is recommended.

The sport of equestrian cross country eventing has seen many serious and even fatal injuries due to rotational horse falls in recent years. The sport originally consisted of horse and rider teams jumping stationary, wood fences. However, in a move towards increasing safety for horses and riders, frangible and deformable safety devices have been emerging in the field. This thesis provides an overview of safety designs that are currently available and those that are on the horizon. Also, a path-finder method of evaluating and developing safety fence designs was outlined and applied to two distinct designs, a hinged gate and a collapsible table fence. A full size prototype of the hinged gate was constructed and tested in the field in two different locations. The collapsible table fence design was developed and then a ½ geometric scale prototype was constructed to demonstrate design feasibility and to analyze design development challenges.

This thesis assesses a systems of the feeding and nutrition of sporting horses which are specialized for the eventing. It deals with a requirement of the energy, individual nutrients, minerals and vitamins. Also it deals with a technology of the feeding horses at each period of the training. The own work is interested in classification of the intake of the energy and amount of the nutrients in the feeding rations at the season of the training, season of the races and at time of the rest in the winter. The feeding rations are assessed in a group of nine horses of the various breeds, age, weight and performance. The discovered values has been compared with the standard nutrient requirements for horses. The monitored values have been: energy, digestible crude protein, various macro and micronutrients, vitamin A and vitamin E. It has followed from the results that the feeding of the horses is individual thing. Intake of the energy and nutrients was tolerated in all cases
