FEI publishes Tokyo horse monitoring research project findings

The results of a major research study commissioned by the FEI, aimed at identifying best practices and management of horses training and competing in hot and humid environments, have been published today.

Conducted at the Ready Steady Tokyo Test Event in August 2019, and led by the FEI’s climate expert Dr David Marlin, the study monitored the combined effects of long travelling times and distances, time zone disruptions, and heat and humidity on competing horses.

Horses were monitored before and during the test event, including how they adapted to the challenging climate in Tokyo. Central to the report is data collected on-course and post-competition, which allowed for detailed analysis of the cross country test.

The study findings show that horses generally coped extremely well with the conditions and remained in good health for the duration of the test event, held at the same time of year as the Games in 2020, despite the fact that conditions were thermally challenging, with Wet Bulb Globe Thermometer* (WBGT) Index readings frequently in the region of 32-33°C.

The report confirms that on cross country day (13 August), the high WBGT Index, steep initial climb and sharp turns on the course produced a significant challenge for competing horses. Heart rates during cross country, and blood lactate, heart rate and rectal temperature after cross country, indicated that horses were working at close to maximal capacity.

A new heart rate monitor that also displays the ECG, plus infra-red thermal imaging to provide a rapid and accurate estimate of horses’ temperature were key pieces of technology used in data collection for the study.

The report highlights that “all possibilities must be explored to mitigate the effects of the likely climatic conditions, including reduction in distance appropriate for the conditions and bringing the cross country start time forward to avoid the highest WBGT conditions that would normally peak between late morning and mid-afternoon”.

Following discussions between the Tokyo Organising Committee of the Olympic and Paralympic Games (TOCOG), the IOC and the FEI, consensus has been reached on advancing the cross country start time to either 07.30 or 08.00 on 2 August 2020 as part of the heat countermeasures. A final decision on the move, which is fully supported by the findings in the Marlin report published today, will be made by the IOC Executive Board.

“We have worked very closely with TOCOG to put in place the best possible heat countermeasures for both our equine and human athletes for Tokyo 2020, and the findings in this important research study will play a crucial role in guiding final decisions on appropriate facilities and support”, FEI Veterinary Director Göran Akerström said. “The report will also be a valuable tool for athletes and National Federations as they prepare their horses in the build-up to and during the Olympic and Paralympic Games.”

Heat countermeasures that are already in place for horses include air conditioned stables at both equestrian venues (Bajikoen and Sea Forest), early morning and evening training and competition sessions under floodlights, constant and close monitoring by a world class veterinary team, and multiple cooling facilities including the provision of shade tents, cooling fans, ice and water, and mobile cooling units.

The FEI has been working on optimising equine performance in challenging climates with Dr Marlin since before the Atlanta 1996 Olympic Games. Dr Marlin has been working with the FEI for the past three years specifically on Tokyo, reviewing historical climate records, analysing data collected at the main venue at Bajikoen (EQP) and at the cross-country course at Sea Forest (SFC), and leading the test event research project.

The findings from the research project have been sent to TOCOG, the IOC, all National Olympic and Paralympic Committees with athletes competing in equestrian sport, and all National Federations affiliated to the FEI.

Notes to Editors:

*The Wet Bulb Globe Temperature (WBGT) index is used to measure heat, humidity, solar radiation and wind factor.

The technology used for data collection during the research project was made available through the FEI’s partnerships with Epona Biotec, Arioneo, Equestic and Polar.

About Fédération Equestre Internationale (FEI) www.fei.org

The FEI is the world governing body for horse sport recognised by the International Olympic Committee (IOC) and was founded in 1921. Equestrian sport has been part of the Olympic movement since the 1912 Games in Stockholm.

The FEI is the sole controlling authority for all international events in the Olympic sports of Jumping, Dressage and Eventing, as well as Driving, Endurance, Vaulting and Reining.

The FEI became one of the first international sports governing bodies to govern and regulate global para sport alongside its seven able-bodied disciplines when Para Dressage joined its ranks in 2006. The FEI now governs all international competitions for Para Dressage and Para Driving.
