This is the first in a series of articles focusing on common training problems, and exercises to correct underlying strength deficiencies.
The Hollow Back
A hollow back is one of the most common poor postural positions seen in the horse. It prevents the horse stepping through correctly, leads to short unbalanced steps and is also the root of many muscular, ligamentary and osteoarthritic problems. Working horses with a good back posture from the outset will not only help to reduce the risk developing back problems but also improve performance potential.
Short topline - long underline
Dip between back of saddle and croup
Hard in the mouth / high head carriage
Difficulties with submission and or contact
Difficulties with engagement
Difficulties with maintaining a round and /or low neck outline
Loss of rhythm
Difficulties achieving a soft and supple back.
Typical Comments from Dressage Judges:
Tight in Neck and Back
Not in self carriage
Horse needs to soften and stretch topline more and accept a softer and more gentle contact
Needs to show more swing through back
Not enough elasticity in the frame
Not always working forwards into a consistent contact and against the hand
How the horse uses himself correctly to achieve a round swinging back when working:
This is related to the degree of both mental and muscular relaxation and recruitment of the flexor chain of muscles. Lowering the head and neck will help to raise the back through the mechanics of the topline (nuchal and supraspinous) ligaments. Engagement of the hind limb helps to support back posture. The more the hind legs engage, the more the back can swing.
Flexor Chain of Muscles
A relaxed neck with no tension in the top line extensor chain of muscles is also essential for the back to swing. The first three qualities of the German Training Scales, rhythm, looseness and contact/acceptance of the bit are of primary importance in the quest to achieving this goal..
Core Muscular Problems:
The flexor chain of muscles, particularly the abdominal and iliopsoas groups, if weak, will inhibit engagement. Tension within any part of the chain will have a knock on effect, thus, discomfort in the extensor chain will inhibit the ability of the flexor chain to work correctly. This problem is particularly common with young horses. It takes many months to develop the necessary muscular strength both for self carriage and to work with a soft swinging back.
The Iliopsoas Muscle Group consisting of psoas major, psoas minor and iliacus lies and attaches onto the ventral side of the lumbar spine, pelvis and the minor trochantor the femur. This muscle group is one of the main contributors to hip flexion and movement of the pelvis through flexion of the lumbo-sacral junction.
Abdominal Muscles. These consist of the rectus abdominae, the transverse abdominae and the internal and external obdominal oblique muscles. As well as supporting the abdominal viscera, aiding breathing and defecation , they also work together to help to create flexion (lift) and latero-flexion of the thoraco-lumbar region of the spine.
Encourage the horse to work long and low with engagement. This gives him the opportunity to work with an upward swinging back. As the horse increases in strength and begins to work towards a more advanced outline allow him to stretch down between sessions of greater collection. Use of poles and appropriate gymnastic jumping exercises encourage the horse to bascule and use his back.
These are effective when performed regularly, 3-5 times per week is ideal.
Carrot Low Between Front Legs
Carrot Low to the Side
Back Lift Scratch Reflex
These three exercises are explained in detail in my book Pilates and Stretching An Exercise Index for Horse Owners and in the Pilates for Horses DVD / Online Video.
Make sure your horse is not overweight as this can contribute to the problem. Have a sports massage therapist check your horse to ensure there is no tension through the back muscles which may be inhibiting the flexor chain. Where possible make sure your horse can get his head down when travelling.
Feeding your horse off the floor is much better for back posture due to the mechanics of the neck and back ligaments.
