Abstract:

Abstract. The objective of this study was to develop new statistical models for genetic estimation of racing performances in German thoroughbreds. Analysed performance traits were "square root of rank at finish", "square root of distance to first placed horse in a race" and "log of earnings". These traits were found to be influenced by the carried weight, which was determined by the horse's earlier performance. Therefore, new traits were developed based on random regression models, which were independent from the carried weights. Heritabilities were first estimated for these created traits "ne

Abstract:

The objective of this work is to provide a mathematical analysis on how a Thoroughbred horse should regulate its speed over the course of a race to optimize performance. Because Thoroughbred horses are not capable of running the whole race at top speed, determining what pace to set and when to unleash the burst of speed is essential. Our model relies on mechanics, energetics (both aerobic and anaerobic) and motor control. It is a system of coupled ordinary differential equations on the velocity, the propulsive force and the anaerobic energy, that leads to an optimal control problem that we sol

Abstract:

The Grand National (GN) attracts high profile press and subsequent public attention. This study aimed to establish if factors influential to non-completion, horse-falls and specific fence risk in the GN supported the measures implemented by the British Horseracing Authority (BHA) to improve equine welfare in the GN. Horse, jockey, trainer and race related factors associated with non-completion, horse-falls and horse-falls at specific fences of the GN were collated over a 22 year period from 1990 to 2012. Descriptive analysis calculated non-completion rates per year, according to age and reason

Abstract:

Limited research has been conducted to investigate the risk factors associated with horses being pulled up in steeplechase races. The aim of this study was to identify risk factors associated with pulled up horses in steeplechase races at Cheltenham racecourse and utilise these to propose preventative strategies to reduce prospective risks of racehorses being pulled up in steeplechase races. Horse and racetrack factors that could be associated with an increased chance of horses being pulled up, extrapolated from previous research into racehorse falls and clinical injury, were identified and co

Abstract:

The racing time and rank at finish traits are commonly used for endurance horse breeding programs as a measure of their performance. Even so, given the nature of endurance competitions, many horses do not finish the race. However, the exclusion of non placed horses from the dataset could have an influence on the prediction of individual breeding values. The objective of the present paper was to develop a multitrait model including race time (T), rank (R) and placing (P), with different methodologies, to improve the genetic evaluation in endurance competitions in Spain. The database contained 6

Abstract:

Horseracing as a high-risk sport can pose a significant risk to equine welfare. To date no epidemiological reviews of fall risk in horseracing have investigated the risks specific to point-to-point (PTP) racing. This study aimed to identify the main race level risk factors associated with horse falls in Irish PTP and to compare these to published findings for hurdle and steeplechase racing. The study used a retrospective case-control design. Relevant variables were identified and information was collated for all PTP races in the 2013/14 and 2014/15 seasons. Race-level variables were analysed t

Abstract:

In the first four decades of the twentieth century, horse racing was one of America’s most popular spectator sports. Members of America’s elite took to breeding and racing horses as one of their preferred pastimes. Coinciding with an increase in immigration and the rediscovery of Mendelian genetics, the idea that careful breeding of thoroughbreds would result in improved horses resonated with Americans worried about racial degeneration. Scientists committed to racial ideologies looked to thoroughbreds—whose owners and breeders maintained extensive pedigree records—to understand the science of

Abstract:

Abstract We formulate an adaptive version of Kelly’s horse model in which the gambler learns from past race results using Bayesian inference. We characterize the cost of this gambling strategy and we analyze the asymptotic scaling of the difference between the growth rate of the gambler and the optimal growth rate, known as the gambler’s regret. We also explain how this adaptive strategy relates to the universal portfolio strategy, and we build improved adaptive strategies in which the gambler exploits the information contained in the bookmaker odds distribution.
