Monday-it for the horse is that dreadful feeling of
muscular tightness, so stiff that the first couple of
strides, before the blood begins to circulate and flow,
are incredibly painful. Meanwhile the owner is
somewhere commenting on how stiff THEY feel and that
they could do with a “good old massage” but don’t even
stop to consider that it may be desperately needed by
the horse that has carted its own weight and that of the
rider around for the entire weekend.
We should briefly (and basically) look at the skeletal
and muscular anatomy of a horse.
The skeleton of the horse
supports soft tissues, providing the framework of the
horse’s body. It protects internal organs such as the
heart and lungs, it is the leverage that provides for
the attachment of ligaments, muscles and tendons. It
provides mineral storage, particularly that of calcium
and phosphorus, and it enables blood cell production in
the marrow of many of the bones.
The front legs of a horse carry 75% of a horse’s weight
and they are not attached to the skeleton via bony
attachments. Amazingly the front legs are purely held
there with ligament and tendon attachments.
Muscles are of course the engine to all movement and
total up to approximately 40-50% of a horse’s body
weight. Muscles attach to the skeleton via tendons and
movement occurs when the muscles contract which causes
the bones and bony parts to move.
Muscles are made up of millions of fibres. When they
become damaged, they contract and lessen the blood flow
into the muscle. Over time, the injury can worsen,
until movement is lessened and lameness becomes visibly
noticed.
