Characterization of Raid Hipico Uruguayo Competencies by Ride Type: Causes of Death and Risk Factors.

Abstract: RHU is the oldest endurance sport in Uruguay. However, despite 80 years of racing, there are no studies to characterize this type of competition, explore rates and causes of death, and identify the associated risk factors. The aim was to characterize the Raid Hipico Uruguayo (RHU) competencies according to the distance (short (SR, 60 km) vs. long (LR, 80-115 km)), the causes of deaths, and the associated risk factors. The study population comprised horses ( = 16,856) that participated in RHU rides from 2007 to 2018. LR were more frequent than SR ( < 0.001). The average speed of winners was higher in SR (32.12 km/h) than in LR (28.14 km/h) ( < 0.001). There were 99 fatalities (5.9 per 1000 starts). SR had greater frequency of high comfort index (CI = Temp [°F] + Humidity [%]) than LR, and LR had greater frequency of low CI than SR ( < 0.001). The percentage of inexperienced horses and those who completed the ride was greater in SR than in LR ( < 0.001). In both types of rides, more horses died during than after the ride, and inexperienced horses were more likely to suffer fatalities than horses with prior experience in the sport ( < 0.05). SR were associated with increased risk of sudden death, while LR were associated with increased risk of death due to metabolic alterations. The high fatality index shown in this work warrants urgent investigation in this sport to minimize mortality associated with RHU-specific diseases.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research aims to review and analyze the Raid Hipico Uruguayo (RHU), the oldest endurance horse sport in Uruguay, focusing on its organization based on ride lengths, causes of horse fatalities, and risk factors associated with them.

Study Sample

  • This study conducted a review on a vast group of 16,856 horses that participated in the RHU racing event from 2007 to 2018. This range allows researchers to analyze different rides and performance aspects across different years and seasons.

Characterization of the Races

  • As per the study, the RHU races can be divided into two categories based on their length: short rides (SR) that cover 60 km and long rides (LR) which span about 80 to 115 km.
  • The frequency of long rides was found to be higher than short rides, indicating that the sport often involves more strenuous and enduring challenges for the horses.
  • The study also highlighted that the speed of the winning horses was higher in the short rides (32.12 km/h) compared to the long rides (28.14 km/h).

Fatality Rates and Associated Risks

  • The review establishes that there were 99 fatalities across the observed period, corresponding to about 5.9 deaths per 1000 starts.
  • An interesting observation was that short-distance rides were executed under relatively challenging comfort index – a metric factoring both temperature and humidity – compared to long rides.
  • The number of inexperienced horses and the ones who managed to complete the race was more prevalent in short rides than in long rides.
  • Across both ride types, a higher percentage of horses died during the race compared to post-race. Also, inexperienced horses were found to be more vulnerable to fatalities than the experienced ones.
  • Short rides revealed a higher risk of sudden horse deaths, whereas long rides demonstrated risks of death due to metabolic alterations.

Conclusion and Recommendation

  • The research concludes by addressing the high fatality rates discovered through the study. It suggests the urgent need for further in-depth investigations to understand and curb mortality caused due to RHU-specific illnesses and conditions.
