the combined parameter of the range of motion of the hind limbs, stride length and stride duration (r ¼ 0.87; P < 0.05) signicantly explained the score. There was no signicant correlation between the score and the locomotor variables at canter. Conclusions and Practical Signicance: the IMS equipment proved to be a reliable system to objectively measure the quality of the locomotor performance of Frie- sian horses. Objective evaluation of gait using these mobile systems may have the potential, to assist the jury in nding useful variables to early select Friesian horses. 50 A preliminary study into quantitative analysis of self- carriage in dressage training C. WHITE * , J. DILLIOTT Nottingham Trent University, School of Animal, Rural and Environmental Sciences, Nottingham *Corresponding author: [email protected] In any competitive sport, the measure for success is to ach- ieve a top level performance. The fastest time, longest distance and nal scores are used to decide winners but sports which determine the victor through subjective means (i.e gure skating, gymnastics and dressage) remain areas of debate. Some attempts have been made to compare dressage judges scores with gait parameters however, the role of objective analysis for applied training purposes remains largely understudied. The aim of this study was to develop a method to quantitatively measure self-carriage of horses during a selected dressage movement using Pegasus Limb phasing system (ETB Ltd.) Nine horses performed the British Dressage Novice 24 test, (2002 version) ridden and judged as per competition regulations and data for Move- ments 7 and 14 give and retake the reins over X in working canterwere analysed. British Dressage denes this selected movement as a test of self-carriage where the horse should maintain balance rhythm. Rhythm is dened as a temporal measurement of the footfalls within the particular gait and the intervals between. In order to test this objectively, three variables; speed (m/s), stride length (m) and stride duration (s) were measured and using the Pegasus GPS system to identify geographical location, the data gathered was sectioned into three key stages of the movement; the initial strides of the movement from a set marker towards X, the phase of the movement over X and the following strides to the completion of the movement. Statistical analysis was carried out using a One Way Anova and post-hoc Bonferroni test and signicant differences in stride duration (P ¼ 0.013) between phases of the movement were found. When ana- lysed individually, some subjects maintained stride dura- tion (P > 0.05) but others did not. On review of judgescomments, these differences were also identied and commented on. Interestingly however, in a number of cases where stride duration was seen to be maintained, signicant differences in speed (P < 0.001) between the initial stage of the movement and last stage were seen and signicant differences in stride length (P < 0.001) between all stages of the movement were identied. This suggests there are indeed changes in tempo rather than rhythm occurred during the movement. This preliminary study highlights the potential role for objective tools to enhance training and education of judges and riders. When trying to establish the quality and correctnessof dressage movements, subjec- tive feedback and evaluation is more often than not relied upon. This study identies the potential role of objective analysis tools for assisting in the development and educa- tion of dressage riders, trainers and judges. 51 Retrospective study of non-completion rates for the show jumping and cross country phases of one day British Eventing competitions T.

Differ- ences in non-completion rates are likely to vary between levels on completion. A greater understanding of non- completion rates is useful in developing methodologies that will help both horse welfare as well as the approach riders may use preparing for and within competition. This study conducted a preliminary investigation into the reasons for non-completion by level of competition. Data from 120 one- day eventing competitions were collected and non- completion in the show jumping and cross country phase was assessed. Data were discriminated by level of compe- tition. Reasons for non-completion were categorised as elimination, withdrawal or retirement. Withdrawal is a voluntary decision taken by the rider before starting the phase, whilst retirement is a decision taken after starting the phase; elimination is forced exclusion this can be for a variety of reasons including failure to complete or attempt an obstacle or incurring a penalty score that breaches a ceiling. 42,180 entries started competition, the overall non-completion rate from starters was 18.91% (n ¼ 7978). Non-completion as a proportion of total starters was determined by level; Intro 28.52% (n ¼ 2,303), Pre-Novice 13.61% (n ¼ 2,519), Novice 18.40% (n ¼ 2,215), Intermediate 24.97% (n ¼ 782) and Advanced 37.32% (n ¼ 159). The percentage of eliminations fell as the level of complexity of competition rose from 70.1% at Intro to 17.0% at Advanced. The proportion of withdrawals rose consistently from 14.3% at Intro level to 69.5% at Advanced level 59.5%. The propor- tion of retirements rose with level; from 15.6% at Intro, 31.0% at Intermediate and 23.5% at Advanced. Eliminations are the most common reason for non completion in lower levels of competition. At lower levels riders may continue to compete after accruing high penalty scores, potentially leading to a higher proportion eliminations or retirements. The lower proportion of eliminations in advanced levels of competi- tion is likely to reect the increased skill and better judge- ment of riders. 52 Start time and effect of order in the dressage phase of afliated British Eventing (BE100 Level) competition T.

A preliminary study into quantitative analysis of self-carriage in dressage trainingC. WHITE*, J. DILLIOTTNottingham Trent University, School of Animal, Rural andEnvironmental Sciences, Nottingham*Corresponding author: [email protected]

In any competitive sport, the measure for success is to ach-ieve a top level performance. The fastest time, longestdistance and final scores are used to decide winners butsports which determine the victor through subjectivemeans (i.e figure skating, gymnastics and dressage) remainareas of debate. Some attempts have beenmade to comparedressage judges scores with gait parameters however, therole of objective analysis for applied training purposesremains largely understudied. The aim of this study was todevelop amethod to quantitativelymeasure self-carriage ofhorses during a selected dressage movement using PegasusLimb phasing system (ETB Ltd.) Nine horses performed theBritish Dressage Novice 24 test, (2002 version) ridden andjudged as per competition regulations and data for Move-ments 7 and 14 ‘give and retake the reins over X inworkingcanter’were analysed.
