Riding with consideration – maintaining a healthy horse's back

The horse's back is extremely important for its stability and movement. It also carries the weight of the rider. A healthy back is essential for your horse's well-being, long-term use, and performance.

Load capacity and rider weight

When weight is placed on the horse's back, the spine bends downward. This restricts the lateral movement of the spine. When moving forward, the standing phase of the legs is extended and the hanging leg phase is shortened. Horses compensate for some of the weight load by tensing their abdominal muscles and arching their backs. However, above a certain load, changes to the back and legs occur over time, as well as pain.

Body weight of rider and horse

For simplicity's sake, only the rider's weight is often considered in relation to the horse's body weight. Regardless of constitution and training condition, a horse can carry a weight load of 10% of its own body weight without damage. With a normal constitution, it can cope with up to 15%. With a weight load of 20% of its own body weight, damage occurs in horses with a normal constitution. Horses with a more resilient physique and a very good level of training can still cope with this load at moderate performance levels. Weight loads of 25% of the horse's own body weight cause permanent damage to the entire musculoskeletal system in all horses.

The weight of all equipment must always be added to the rider's weight. Including the saddle, the equipment alone weighs an average of ten kilograms.

Individual factors

However, a horse's load-bearing capacity does not depend solely on its own weight. It must be assessed on an individual basis. Additional influencing factors are:

  • Size and age of the horse
  • The horse's level of training and musculature
  • Nutritional status, body condition score of the horse (see relevant article)
  • The horse's physique (width of the loin, circumference of the cannon bone, exterior defects)
  • Type, duration, and intensity of use
  • Size and riding ability of the rider
  • Weather, season, and ground conditions

Young, old, overweight or underweight horses, as well as poorly muscled and poorly trained horses, can only tolerate lower weight loads. In general, horses can carry more weight during moderate endurance work than during short, intense work. Horses with broad, well-muscled backs are more capable of carrying weight. Advanced riders with a supple seat may be heavier than beginners with an unbalanced seat.

Cannon bone load index

The cannon bone load index is another criterion for assessing a horse's load-bearing capacity. This is calculated using the circumference of the cannon bone and the horse's body weight:

Cannon bone circumference (cm) x 100 / body weight of the horse (kg) = cannon bone load index (RI)

The higher the RI, the more load-bearing the horse is. An RI greater than 4.4 indicates good load-bearing capacity. Strong ponies have a higher load-bearing capacity relative to their body weight than cold-blooded breeds or graceful Arabians. Some examples of this are:

  • Shetland pony 7.4
  • Icelandic horse 4.7
  • German riding pony 4.5
  • English Thoroughbred 4.4
  • Hanoverian 3.7
  • South German Coldblood 3.0

Horse back pain
The ergonomic training posture of the horse

During training, it is important that the horse maintains an ergonomically correct posture. This increases your horse's carrying capacity and protects it from back injuries. The higher the weight load, the more important it is to maintain an ergonomic training posture.

By nature, the forehand carries 52% of the horse's weight. The additional weight of the rider puts even more strain on the forehand. The aim is for the horse to carry itself with the help of well-trained muscles.

Well-trained back and abdominal muscles create core stability. This protects joints, tendons, and ligaments from strain and is essential for symmetrical movements. A symmetrical body protects individual structures from strain by distributing the load evenly.

The movement impulse generated in the hindquarters is transferred via the back to the forehand and neck. Whether you are working in hand, lunging, riding, or participating in other equestrian sports, make sure there is a positive arc of tension. This causes the horse's back to arch. The training should lead to active carrying of the trunk in order to relieve the forehand. This requires well-trained trunk-carrying muscles and a hindquarters that can step under.
