Evaluation: What is Balance?
1998 Cherry Hill ©
a judge examines your horse in a halter class, he or she is looking for balance.
When your trainer or instructor says a particular horse is "balanced",
what does it mean? Balance refers to the relationship between the forehand and
hindquarters, between the limbs and the trunk of the body, and between the right
and the left sides of the horse. A well-balanced horse has a better chance of
moving efficiently with less stress.
center of gravity is a theoretical point in the horse's body around which the
mass of the horse is equally distributed. At a standstill, the center of gravity
is the point of intersection of a vertical line dropped from the highest point
of the withers and a line from the point of the shoulder to the point of the buttock.
This usually is a spot behind the elbow and about two thirds the distance down
from the topline of the back.
the center of gravity remains relatively constant when a well-balanced horse moves,
most horses must learn to rebalance their weight (and that of the rider and tack)
when ridden. In order to simply pick up a front foot to step forward, the horse
must shift his weight rearward. How much the weight must shift to the hindquarters
depends on the horse's conformation, the position of the rider, the gait, the
degree of collection, and the style of the performance. The more a horse collects,
the more he steps under his center of gravity with his hind limbs.
the forehand is proportionately larger than the hindquarters, especially if it
is associated with a downhill topline, the horse's center of gravity tends to
be forward. This causes the horse to travel heavy on his front feet, setting the
stage for increased concussion, stress, and lameness. When the forehand and hindquarters
are balanced and the withers are level with or higher than the level of the croup,
the horse's center of gravity is located more rearward. Such a horse can carry
more weight with his hindquarters, thus move in balance and exhibit a lighter,
freer motion with his forehand than the horse with withers lower than the croup.
When evaluating yearlings,
you need to take into consideration the growth spurts they have which make them
have an uneven topline temporarily. However, be suspicious of a two-year-old that
shows an extreme downhill configuration. Even if a horse's topline is level, if
he has an excessively heavily muscled forehand in comparison to his hindquarters,
he is probably going to travel heavy on the forehand and have difficulty moving
horse has approximately equal ratio between his front "leg" and his
depth of body. The "leg" (lower limb length) is measured from the chest
floor to the ground. It should be equal to the distance from the chest floor to
the top of the withers. Proportionately shorter lower limbs are associated with
a choppy stride.
horse's height or overall limb length is measured from the point of withers to
the ground. It should be equal to the length of the horse's body which is measured
from the point of the shoulder to the point of buttock. A horse with a body a
great deal longer than its height often experiences difficulty in synchronization
and coordination of movement. A horse with limbs proportionately longer than the
body may be predisposed to forging, over-reaching and other gait defects.
viewing a horse overall, the right side of the horse should be symmetric to the
left side. Asymmetry from left to right can lead to stiffness in one direction,
difficulty bending or performing maneuvers to one side, or even lameness from
left to right imbalance.
horses with imperfect balance have become great performers, in general a balanced
horse has an easier time performing and a better chance of staying sound.
