Optimising Show Horse Performance,

With Particular Reference to the Athletic Spine and Head Carriage

CONFORMATIONAL FAULTS

• Does not fill the eye on 1st appearance

–Unbalanced

Woodlander Farouche ; supermodel of the dressage world with the WOW factor

The Show Horse with the WOW factor

• Go Forward• Good rhythm & cadence• Correct flight path limbs• Supple spine• Comfortable ride• Temperament pertinent to class• Fit for purpose for job in hand

UNSTEADY HEAD CARRIAGEUncomfortable

UnbalancedNot going forward

The Athletic Back• Anatomy• LOOK & YOU WILL SEE !!

The skeletal top line and the bird’s eye views show areas of bone available for optimal muscle attachment. i.e.

• Flat of ribs• Side of dorsal processes• Lateral processes of lumbars• Flat of upper hind limb bones

– Ham string and thigh muscles “size”

The Athletic Back

Example of conformation faults in the forehand of competition horses

Attention to detail from day 1Producer/Farrier/Vet/Nutritionist

LIMB ABNORMALITIES THE FEET

• SLIGHTLY ODD FRONT FEET

• ESPECIALLY HEEL DEPTH

• NO HEEL SUPPORT

• WEAK HOOF CAPSULES

• SIGN OF LAMINITIS

• UNEVEN HEEL DEPTH → Uneven scapular height → Asymmetrical Shoulders re: saddle fit

How to assess foot balance, left and right handed farriers

• ALL rotational and angular limb deformities out 8/10 rule

• Overdeveloped muscles indicate lameness behind

The Competition Horse conformational faults

BACK AT THE KNEE

Back at the kneepredisposes to check ligament strain &

inflammation of the knee joints

• Examples of conformation faults causing multifactorial problems in the Competition Horse/hindquaters

THE HINDQUARTERS

• The flatter the pelvis • → More muscle• → Greater strength and flexibility

• STRAIGHT HIND LEGS → Unable to come under the horse

• ACUTE HOCK ANGLE → Less able to carry weight

• TARSAL VALGUS → Risk of Pelvic fractures

Quarters width should be parallel with thighs

THREE-POINT BALANCE PLUS EXCURSION

Three-point balance refers to the correct function of:-

1. The incisors2. The molars3. The mandibular (jaw) joint

Three-point balance allows normal jaw movements to take place and is achieved by:-

• The removal of hooks• The removal of sharp points which

develop on the outside of the upper and the inside of the lower premolars and molars

• Adjusting the line of the incisors

• HEAD CONFORMATION → JAW JOINT PAIN• → One sidedness• → Head Tilt• → Uneven back muscle development• → Poor saddle fit• → Hind leg lameness

CONFORMATIONAL FAULTS

• Does not fill the eye on 1st appearance– Unbalanced

NECK• Crest fat laminitis

• Hollow in front of withers – dorsal spinal ligament – weak build

up ventral muscles

LONG BACK – More Flexible →SI Disease

ROACH BACK - Unsightly but not usually a problem

SHORT BACK – Kissing Spines

“SLACK LOINS” → SI disease

Core muscles 1

Core muscles 2

CORE STRENGTH

• Critical to build up horse’s and your own core muscle strength.

• Rider ; independent seat• Horse ; steadily increasing fittening• extreme care when riding at • extended trot on weak • young horse

Rider/horse and pony EMPATHY• Charlotte Dujardine OBE• Balance and harmony with Valegro

Work overload in weak young horse

• will cause • loading of hind quarters• tying up • • leading to • gait on the forehand • splints• joint problems
