Research Into Training Programs Needed To Protect Equine Tendons

The superficial digital flexor tendons in a horse's front legs are responsible for much of the animal's athleticism: They store energy and play a critical role in the efficiency of the horse's trot and gallop. However, these tendons are especially susceptible to injury: They are one of the most common causes of lameness in performance horses. Tendon injuries are slow and difficult to heal, so it's imperative that they be detected early and that training methods be adapted to allow time for the tissues to heal.

Drs. Claire O'Brien, Neil Marr and Chavaunne Thorpe investigated the biomechanical and biothermal effects of strain on this tendon and how both forces contributed to microdamage. Though the tendon is essential for efficient performance and locomotion, it has a very narrow window for error, which makes it susceptible to injury.

The trio reviewed 140 scientific papers and discovered that most superficial digital flexor tendon injuries occur during fitness work. Risks to tendons include variations in training intensity and frequency, surfaces and equipment. Individual risk factors include breed, age and sex; variations in tendon blood supply, strength and flexibility may contribute to chronic tendon injuries and longer recover rates.

The team suggest that research be done in several areas so that recommendations based on scientific principles can be made for training programs; these would minimize the risk of tendon injury. They also suggest that those involved in a horse' training understand the following:

  • The physiologic demands high-intensity training places on equine tendons
  • Heavy training sessions that mimic competition should be closely monitored and only repeated every 72 hours to allow tendons enough time to repair and adapt. Factors such as the horse's age, history of injury and previous competition experience should help guide decision making on the frequency of training sessions
  • The effects of other factors like surface type, fence height, bandaging and ambient temperature place on tendon temperature and strain
  • Training should be increased incrementally over time, using objective measures to gauge each horse's physiologic response

HRI Reveals 2021 Fixture List

Horse Racing Ireland has published its 2021 fixtures list with 380 meetings, up from the originally scheduled 370 in 2020. The list contains 379 meetings with one designated as a floating fixture to be programmed when demand for opportunities is high. The 10 additional meetings include seven turf fixtures (including the floating fixture) and three all-weather meetings.

Jason Morris, HRI’s director of racing, said, “The 2021 fixture list has very largely reverted to the original 2020 schedule with the number of blank Sundays being retained at six to help ease pressure on stable staff and trainers. As we all know, 2020 was severely impacted by the 11-week cessation of racing from Mar. 26 to June 8 due to the Covid-19 pandemic, after which it has featured a heavily revised schedule with 330 fixtures being retained overall.

“The HRI Board recognises the uncertain times we are facing, but wanted to produce a full-year fixture list at this stage to assist owners, trainers and racecourses with their planning. In the event that racing is disrupted or attendances are not permitted or heavily restricted for a prolonged period in 2021, it is recognised that revisions to the schedule may be necessary. In such circumstances, HRI will be flexible and respond to the circumstances as we find them with regard to dates, venues and codes of meetings; however the strong preference will be to run the full schedule of fixtures as published today.”

Owners To Return To Irish Racecourses From Monday

Owners will be permitted to return to Irish racecourses from Monday in line with the government’s medium-term COVID-19 plan published earlier this week.

Brian Kavanagh, chief executive of Horse Racing Ireland, said, “We are delighted to confirm that for the first time since Mar. 13, owners will be permitted to return to the racecourse from Monday next. Owners play the most important role in Irish racing and they have had to wait quite some time to return to the racecourse to see their horses run. We have always said that getting owners back on the racecourse was our first priority and we have been working closely on this with the Association of Irish Racehorse Owners and their representative Caren Walsh.

“As all key personnel who have been racing behind closed doors since June 8 will testify, these are not race fixtures as we used to know them, and given the ongoing public health risk it remains as important now as it ever has been that all those attending racecourses adhere strictly to the race day protocols.

“Since we resumed racing in Ireland, the level of care and compliance with the Covid-19 protocols has been excellent and it is vital that everybody continues to comply with the rules on the racecourse around pre-health screening, social distancing and the wearing of face masks or coverings at all times.”
