The Link Between Exercise Intensity and Equine Gastric Ulcer Development: Balancing Training and Gastric Health

Equine gastric ulcers are a common issue among horses, particularly those involved in high-intensity training and competition. These ulcers can significantly impact a horse’s performance, comfort, and overall well-being. Understanding the factors contributing to gastric ulcer development is crucial for managing this condition effectively. While various factors play a role in ulcer formation, research suggests a significant correlation between exercise intensity and gastric health in horses.

The Impact of Exercise Intensity on Gastric Health

High-intensity exercise, such as rigorous training sessions and competitive events, places significant physiological stress on horses. This stress not only affects musculoskeletal and cardiovascular systems but can also affect the gastrointestinal tract. During intense exercise, blood flow is redirected away from the digestive system to support the increased demands of working muscles. Exercising on an empty stomach can increase the risk of Equine Squamous Gastric Disease (ESGD), as the acidic juices in the stomach can splash around and are in closer contact with the squamous mucosa.

The physical exertion associated with intense exercise can exacerbate existing gastric ulcers or increase the risk of developing new ones. Therefore, it’s essential for horse owners, trainers, and riders to recognise the relationship between exercise intensity and gastric health to implement appropriate measures.

Strategies for Balancing Training and Gastric Health

  1. Gradual Conditioning Programs – Implementing gradual conditioning programs may help acclimate horses to increasing levels of exercise intensity gradually. By gradually increasing the duration and intensity of workouts, trainers can help reduce the stress placed on the horse’s body while still achieving fitness goals.
  2. Dietary Management – Proper nutrition plays a critical role in maintaining gastric health in horses engaged in high-intensity exercise. Providing frequent access to forage and ensuring a consistent feeding schedule may help buffer gastric acid and avoid prolonged periods of fasting, which can exacerbate ulcer formation. Incorporating specialised feeds designed to support gastric health, such as those containing alfalfa, may also help to reduce the risk of gastric ulcers.
  3. Supplementation and Medication In some cases medication may be necessary to manage gastric ulcers in horses. Proton pump inhibitors (PPIs) and histamine receptor antagonists (H2-blockers) are commonly used to reduce gastric acid production and promote ulcer healing. However, it’s essential to consult with a veterinarian before initiating any medication regimen to ensure proper dosing and usage.
  4. Stress Management Techniques – Implementing stress management techniques may help reduce the physiological stressors that contribute to gastric ulcer development in horses. Techniques such as regular turnout in a natural environment, socialisation with other horses, and providing opportunities for mental stimulation may help alleviate stress and promote overall well-being.
  5. Environmental Modifications Creating a supportive environment for horses can also aid in maintaining gastric health during training and competition. Providing access to clean water at all times, ensuring proper ventilation in stables, and reducing exposure to environmental stressors, such as excessive noise or temperature fluctuations, may help to reduce stress and therefore the risk of gastric ulcers. Optimising turnout time and space can provide horses with opportunities for natural grazing and movement, which should support digestive health and overall comfort.

Monitoring and Adjusting Training Regimens

Regular monitoring of horses’ behaviour, performance, and overall well-being is essential for identifying early signs of gastric ulcers and adjusting training regimens accordingly. Changes in appetite, weight loss, decreased performance, or behavioural changes may indicate gastric discomfort or ulceration and warrant further evaluation by a veterinarian. By maintaining open communication with equine health professionals and being proactive in addressing potential gastric health issues, horse owners and trainers can optimise training programs while prioritising the well-being of their equine athletes.

Achieving Optimal Equine Performance and Gastric Health

The link between exercise intensity and equine gastric ulcer development underscores the importance of carefully balancing training regimens with gastric health considerations. By implementing strategies such as gradual conditioning programs, dietary management, and appropriate supplementation, horse owners and trainers may be able to reduce the risk of gastric ulcers and support the overall well-being of their horses.

Ongoing monitoring and collaboration with veterinary professionals are also essential for identifying and addressing gastric health issues promptly. By prioritising gastric health alongside training goals, horse enthusiasts can help to ensure optimal performance and longevity for their equine partners.
