Qatar- QF researchers explore technique to assess readiness of horses before race

(MENAFN- Gulf Times) In a collaborative effort between Qatar Foundation entities, researchers from its Equine Veterinary Medical Centre (EVMC), Al Shaqab's endurance department and Weill Cornell Medicine-Qatar (WCM-Q), have been exploring the use of a technique called 'metabolomics' to assess the readiness of a horse before a race. 
'Metabolomics is a relatively new technology used to measure hundreds of small molecules called metabolites, found in a biological sample. Metabolites are the products of constantly occurring and life-sustaining chemical reactions in all living organisms.
'Their production and removal from the blood stream is dependent on multiple factors including genetics, diet and lifestyle. Any change in these factors is reflected by a change in specific metabolite levels, which allows them to be used as biomarkers, said Dr Tatiana Vinardell, head of Research and Education, EVMC.
A pilot-study on equine metabolomics was inspired by Prof Karsten Suhre, director of Bioinformatics Core at WCM-Q and his desire to create a 'health and fitness passport for athletes. It turns out that horse endurance races are just the ideal test environment to explore such an idea.
'Every living organism has a metabolic fingerprint and by frequently monitoring this fingerprint, we can establish the reference or baseline metabolic readings indicative of that organism's wellness. 'Any changes in the health of the organism can be detected by comparing their metabolic state to their established baseline. If a considerable change is seen between the two, it can be indicative of a health problem that should be further investigated, said Prof Suhre.
Metabolomics research in human athletes has provided important insights into energy demands and training physiology, allowing scientists to identify novel biomarkers associated with better performance.
This field is lagging in equines despite their prevalence in competitive sports. Some preliminary studies have been done in Europe, but they cannot be applied to horse races in a desert region due to the vastly different weather conditions.
'Our aim in this pilot study was to perform an in-depth investigation of the metabolic consequences of endurance riding, which may ultimately allow us to establish a metabolic performance profile for the horses that finished a race successfully. This profile can then be used as a reference to determine whether an animal is biochemically ready to participate in an endurance competition, said Dr Anna Halama, assistant professor, Research in Physiology & Biophysics, WCM-Q.
The group studied 62 horses a mix of pure Arabian and half-Arabian breeds, all of which were experienced in endurance riding. Their blood samples were collected before and after the race in up to three different competitions and metabolic-based profiling was conducted using a technique called mass spectrometry, using a platform established in collaboration with the Antidoping Lab in Qatar. They measured 805 metabolites, out of which 437 showed significant alterations after the race.
'We compared the metabolic profiles of the horses that were eliminated to those that finished the race and were able to identify six metabolites that could predict equine performance in endurance competitions. Some of the metabolites that we identified could also serve as performance indicators of the horses while others could be used to optimise diet to enhance performance, said Dr Halama.
Having finished this pilot study, the groups now plans to repeat the study with a bigger sample size to corroborate their results and further investigate the identified metabolites.
