Shoeless Thoroughbred Wins at Keeneland; Track Lists Barefoot Entries as Trainers Experiment with Polytrack Surface Effects on Hoof Slide
 |
| The racing surface known as "Polytrack" is one of several artificial surfaces that have been installed at racetracks in North America to improve safety and help cope with bad weather. But it also changes the way the hoof interacts with the surface. The characteristic slide that horses experience on dirt can be "sticky" for some horses. Experimenting with and without shoes during training and racing has led some trainers to try some unorthodox combinations of shoes--or no shoes at all. |

Hoofcare University: Biomechanics of Racehorses' Lower Limbs and Track Surface Interface Video Lectures with the University of Guelph's Dr Jeff Thomason
 |
| Dr Jeff Thomason |
Dr Thomason is widely known for his research, which currently looks both at the biomechanics of the horse's foot and distal limb as well as the mechanical properties of the track itself, and how they influence the function of the foot.
Recently, Dr. Thomas was part of a group of authors that created an extensive "white paper" reference document for the Grayson-Jockey Club Foundation's Welfare and Safety of the Racehorse Summit on this type of dual research, which will ultimately benefit the safe travel of horses over optimal racing surfaces.
Plan to spend the next 15 (or so) minutes absorbing Dr. Thomason's lecture points, which have been broken down into bite-size videos.
Introduction:
How do you examine limb mechanics?
How do banked surfaces affect impact?
Can optimizing track surface reduce catastrophic injury:
Who will benefit from the racing surfaces 'white paper'?
What is the best track surface for racing?
How does climate affect track surfaces?
How does maintenance affect track surfaces?

| The surest sign of an outstanding lecture is when you go back into the lecture hall half an hour later and the lecturer is still brainstorming with attendees and other speakers. Here's Dr Thomason two years ago at the University of Pennsylvania's New Bolton Center farrier seminar. With him: Dr Bryan Fraley of Kentucky and farrier Jaye Perry of Georgia.

Racetrack Surface Research Video: Building a TTD for the Track in a Box at the University of California
3 February 2010 Fran Jurga's Hoof Blog at Hoofcare.com
(Caution: You might want to turn down the volume on your computer before you play this video. The soundtrack is loud!)
This video shows the development and constrution of the University of California, Davis, J.D. Wheat Veterinary Orthopedic Research Laboratory track-testing device (TTD). The TTD is instrumented with a load cell, accelerometer, and laser displacement sensor, and is used to compare the dynamic properties of Thoroughbred racehorse racetrack surfaces as part of the lab's "Track in a Box " project to simulate racetrack conditions in the laboratory.
The "box" in the lab acan be filled with layers of dirt, stones, asphalt and racetrack surface materials that could include wax, fibers or other materials. A drainage system allows the effects of rain to be testing. The spring-loaded mechanism simulates the impact of pounding hooves up to 100 times the force of gravity while measurements are taken to characterize surface behavior.
The finished TTD positioned over the box
The "Track in a Box" project is the work of Jacob Setterbo, a PhD candidate in the Biomedical Engineering Graduate Group, and Dr. Susan Stover, director of the school’s JD Wheat Veterinary Orthopedic Research Laboratory. The project is funded by the Grayson Jockey Club, the Southern California Equine Foundation, and the Center for Equine Health with funds provided by the State of California pari-mutuel fund and contributions by private donors.
I asked Jacob Setterbo about the fact that the TTD contained everything exect a shoe, and wondered about adding a shoe to the TTD, or even using it to test how different shoes load in different footing. Setterbo and Stover worked on a sensor shoe for racetrack testing which was featured on the hoof blog in an article last fall.

Setterbo and Stover worked on a sensor shoe for racetrack testing which was featured on the hoof blog in an article last fall.
"That is a possibility we considered," Setterbo answered. "So the TTD was designed so that a new interface to the load cell can be machined so that a shoe can be added, and things such as toe grabs can be compared. Because we first need to establish the functionality of the TTD we decided to first start with a simple impacting part, which is an aluminum piece which is approximately the same area of the hoof. But the answer is yes, it is possible to modify the TTD to test different shoes."

California Statistics Reveal Dangerous Trend in Hind Limb Breakdowns on Artificial Tracks
by Fran Jurga | 28 August 2009 | Fran Jurga's Hoof Blog
Data on racing breakdowns compiled by the University of California at Davis tracks the incidence of injuries, the seasonality of injuries and which limb is affected, among many other data points recorded. A publication of recent statistics presented to the California Horse Racing Board (CHRB) reveals a disturbing prevalence of hind limb injuries that led to the death of racehorses last year.
While the report is not available at present, the Los Angeles Times today reported that the study presented to the CHRB yesterday reveals that 19 horses died on California tracks from hind limb injuries in 2008, and that those injuries were split pretty evenly between left and right hinds. Only one horse died from a hind limb injury on a dirt track.
Breakdowns on the front limbs were somewhat more comparable between dirt and artificial tracks, but the artificial breakdowns still exceeded the dirt tracks: 74 horses broke down in front on artificial tracks while 59 broke down in front on dirt tracks.
Some people feel that this is an invalid comparison, and that trainers will often work a horse on a synthetic track that they would not work on a dirt track.
UC Davis examined 351 cadavers of breakdowns in its search for new insights into why racehorses are so susceptible to fatal injuries.
California has a 4 mm limit on toe grabs on front shoes and allows horses to run barefoot.
