Het algemene beeld is dat de geïnterviewde paardenhouders denken dat de paarden in de weide of paddock niet reageren op het coronageluid. Een enkele paardenhouder geeft aan dat sommige paarden een korte gewenningsperiode nodig hebben in geval van coronageluid, zoals ook bij andere, nieuwe geluiden het geval kan zijn. Deze bevindingen zijn overeenkomstig met de voorafgaande literatuurstudie: “gesteld kan worden dat het niet aannemelijk is dat paarden hinder ondervinden van coronageluid tijdens het weiden in de buurt van bovengrondse hoogspanningsverbindingen” (Visser and Neijenhuis, 2015). De paardenhouders baseren hun mening op het feit dat paarden weiden en grazen onder de draden zonder ze te mijden of omhoog te kijken. Hiermee wordt door hen gesteld dat het niet aannemelijk is dat de paarden hinder ondervinden van het coronageluid in de weide of paddock in de buurt van bovengrondse hoogspanningsverbindingen.

The forces exerted by a rider on a horse have a direct influence on the mechanical load experienced by the horse and consequently on its motion pattern. The aim of this thesis is to explore the biomechanical interaction between rider, saddle and horse in order to get insight in the loading of the horse and to identify potential opportunities to reduce load-related injuries. The influence of man on the horse is mediated trough tack, which functions as an interface between the horse and the human being(s) using it. The tack is often connected to both horse and rider and is therefore well-positioned to incorporate measuring devices that can record the forces between horse and rider.

So-called saddle-pressure measuring devices have been used to evaluate saddle-fit and could also be a useful tool to study the interaction between horse and rider. However, not much was known thus far about the validity, reliability and usability of these devices for this purpose. Therefore, the first studies in this thesis focussed on this topic. The FSA system was only reliable in highly standardised circumstances. The Pliance system provided reliable and repeatable results and can be used indeed to study the interaction between horse and rider. In this thesis it was used to evaluate the effect of rider position on the force distribution beneath the saddle and to study the signals given by the rider to the horse performing lateral movements in dressage.

One of the important physical properties of the rider that influences the horse is the rider’s weight. The effect of tack and weight on the movements of the horse was therefore studied. The introduction of a mass with considerable weight on the horse’s back induced an overall extension that might contribute to back injuries.

During trot, the rider can either rise from the saddle during every stride (rising trot), or remain seated (sitting trot). The back movement during rising trot showed characteristics of both sitting trot and the unloaded condition, with a higher degree of extension during the sitting phase and less extension in the standing phase. In the standing phase peak force on the stirrups is higher, but the overall vertical peak force on the back of the horse is less. This supports the general assumption that rising trot is less demanding for the horse than sitting trot.

Three spring-(damper-)mass models were constructed to evaluate the biomechanical requirements the rider has to comply with during sitting trot, when using the modern riding technique adopted by jockeys during racing, and in rising trot. The models demonstrate which combinations of rider mass, spring stiffness and damping coefficient will result in these riding modes. Optimization to minimize the peak force of the rider and to minimize the work of the horse resulted in an “extreme” modern jockey technique, which is not adopted by actual riders. The incorporation of an active spring system for the leg of the rider, was needed to simulate the rising trot.

The general discussion argues that the simultaneous use of a variety of approaches is required to further our understanding of the interaction between horse and rider. A combination of experimental research, which makes use of cutting-edge techniques to measure kinematics of horse and rider, forces acting between horse and rider and between horse and environment, and muscle activation patterns of both horse and rider, with mathematical modelling is the way forward. This combined approach could answer questions concerning the external and internal biomechanical loading of horse and rider of several horse riding and training techniques. Techniques that minimize risk of injury of both horse and rider could possibly be identified, reducing welfare problems of the equine athlete.

Relevance of test information in horse breeding

The aims of this study were 1) to determine the role of test results of young

horses in selection for sport performance, 2) to assess the genetic diversity

of a closed horse breed and 3) the consequences of inbreeding for male

reproduction. The study was performed using existing databases containing

records collected on young horses during inspections, which were linked to

databases containing records on sport performance. Multivariate animal

models were applied in estimation of genetic parameters. Heritability

estimates of movement and free-jumping traits collected at Studbook Entry

and at First Stallion Inspection were moderate to high. Free-jumping traits

collected at both inspections showed high to very high positive genetic

correlations to show-jumping in competition. Movement traits collected at

both inspections showed favourably genetic correlations to dressage in

competition.

Subsequently, the effect of limb and foot conformation, in particular the

trait uneven feet, as assessed at Studbook Entry Inspection on performance

and length of sport career have been analysed. Limb and foot conformation

had only weak to moderate genetic correlation to sport performance. Some

foot conformation traits could be identified as risk factors for early

retirement from sports; e.g. occurrence of uneven feet shortened the

competitive life at elite level of jumping.

The development of genetic diversity in a closed breed have been studied

using the pedigree structure of the Friesian horse breed. Considerable loss

of genetic diversity have taken place during the history of the studbook,

corresponding to an average inbreeding rate of 1.3% per generation. Loss of

genetic diversity was mainly due to drift from small effective population size

during several generations. In a subsequent analysis the relation of

inbreeding with semen quality of young Friesian stallions was investigated. It

was concluded that low semen quality in Friesian stallions could not be

attributed to inbreeding. Heritability estimates for semen quality traits were

moderate to high and had substantial variation. Selection can be used to

improve semen quality.

Finally, opportunities for improvement of the breeding program have been

discussed. Selection potentials are calculated to gain insight in the relative

importance of each of the young horse tests to the breeding program.

Additional opportunities to increase selection response have been

discussed.

Training in equine sports is largely based on experience and intuition. To optimize the training of equine athletes, there is a need for objective measurements of biomechanical, sport physiological and behavioral parameters. These parameters can be used by trainers to improve their training strategy.

Only a small handful of novel studies have been published since the 2006 Lausanne meeting on hyperflexion. Unfortunately, these studies have tended to be marred serious flaws in methodology, limited numbers or unhelpful parameters used. This leads to the conclusion that there is still insufficient scientific evidence to confirm unequivocally whether or not there are welfare issues involved in training techniques using hyperflexion.

In de warmbloed paardenfokkerij vindt in toenemende mate selectie plaats in twee hoofd fokrichtingen: één gericht op het fokken van een goed dressuurpaard en één gericht op het fokken van een paard met uitstekende springkwaliteiten. De opfok van de jonge paarden vraagt veel tijd en geld. Het resultaat van deze investering blijft echter lang onzeker. Pas als de paarden gaan presteren blijkt of de verwachtingswaarde wordt waargemaakt. In het JUMPEX project hebben we gekeken naar mogelijkheden om al tijdens de opfokperiode een betere inschatting te kunnen maken van de latere prestaties van springpaarden. Het project is uitgevoerd door de divisies Praktijkonderzoek en Dier & Omgeving van de Animal Sciences Group en de Hoofdafdeling Gezondheidszorg Paard van de Faculteit der Diergeneeskunde. Het project is gefinancierd door het Productschap Vee en Vlees (op advies van de Sectorraad Paarden) en het Ministerie van Landbouw, Natuurbeheer en Voedselkwaliteit. In dit handboek staan de resultaten van het onderzoek. Heeft training op jonge leeftijd zin en of kan al op jonge leeftijd op kenmerken geselecteerd worden? Op basis van resultaten van het JUMPEX onderzoek geeft het handboek praktische adviezen over trainings- en selectiemogelijkheden van springpaarden. Goede instrumenten voor de sector om de kwaliteit van het Nederlandse springpaard verder te verbeteren.
