草莓污视频导航 research aims at improving chuckwagon horse safety

Study looks at how different track conditions impact stress on leg joints

Horses are a marvel of physiological engineering. With powerful lungs, large hearts and legs that can bear a considerable amount of weight, they have the potential to be top athletes.

But like their human counterparts in competitive sports, horses working at a high level of physical exertion have a risk of injury.

Dr. Renaud L茅guillette, DVM, PhD, professor at the (UCVM), has a passion for these equine athletes. He has spent years researching ways to improve the health, safety and performance of horses at the Calgary Stampede. This year, his research focuses on the surfaces chuckwagon horses run on, with a look at reducing the risk of leg fractures.聽

鈥淲e are looking at track conditions and the effect of different footings 鈥斅燼t varying depths and levels of hardness 鈥斅爋n the impact on the legs,鈥 says L茅guillette, Calgary Chair in Equine Sports Medicine.

Big picture goal: Improving chuckwagon horse safety

L茅guillette is joined by some heavy hitters in the project, which aims to help the Calgary Stampede optimize track conditions to improve safety. He has teamed up with an expert in exercise-related human tibial fractures, Dr. W. Brent Edwards, PhD, in the , and with Dr. Thilo Pfau, PhD, who researches high performance equine biomechanics. Pfau is jointly appointed in the faculties of Kinesiology and Veterinary Medicine. Rounding out the team of experts is Olivia Bruce, a biomechanics scholar, and a PhD candidate in 草莓污视频导航鈥檚

鈥淚t鈥檚 a great collaboration, with the goal, the big picture, being to improve the safety or help prevent what we call catastrophic failure during racing, which is where the horse gallops hard and then suddenly there's a fractured bone,鈥 says L茅guillette. 鈥淲hich happens also in humans, by the way, not just horses.鈥

Before the Stampede, the researchers ran chuckwagon horses on different levels of footing depth and firmness over distances of 100 and 200 metres. The horses galloped with a rider at full speed with sensors to measure acceleration and impact on the legs.

鈥淚f you punch your fist on a wall, that鈥檚 deceleration, going from high speed to zero. That鈥檚 exactly what happens when they run.鈥

Collecting data to help prevent leg bone fractures

In the prevention of leg bone fractures during racing, the track is one of the parameters that can be controlled. To collect data on different track conditions, sensors were placed on the horses鈥 hooves, cannon bones, and radiuses, using saddles fitted with a device measuring all the data.

鈥淩ight now, it鈥檚 an observational study, meaning when you change the track condition, we are looking at what happens to the legs of the horses. I'm not saying we'll immediately find the perfect track condition, but we are measuring and documenting and will be publishing our results.

鈥淚t鈥檚 cool because it's a collaboration with human kinesiology, veterinary medicine, the Stampede, and the chuckwagon horse owners are absolutely behind this project and are really great to collaborate with. They just want to make it work,鈥 says Leguillette. 鈥淭his is a nice, nice project.鈥
