πThe extensor chain and performance horses.
πThis chain is largely responsible for forward propulsion. The better conditioned these muscles are, the more powerful the movement. For example the horse can only perform a really powerful extended trot, leaving the rope box correctly or driving off the back of a barrel in barrel racing .
πThe Splenius Muscle originates from the spinous processes of the withers and Nuchal Ligament and inserts onto the poll and the first four cervical vertebrae. This muscles works to extend and elevate the neck.
πThe Longissimus Dorsi, part of the erector spinae group of muscles, is a long, strong muscle that runs along the top of the thoracic and lumbar spine to the pelvis attaching to each vertebrae. It supports and extends (hollows) the spine and contributes to lateral flexion.
πThe Gluteal Muscle Group, consists of the superficial, medial and deep gluteal muscles. The Medial Gluteal or Glutimus Maximus is the largest and most powerful gymnastic muscle of the hind quarter primarily involved in creating extension of the hip joint during propulsion.
πThe Hamstring Muscle Group consists of the Biceps Femoris, Semi-tendinosus and Semi-membranosus muscles. These powerful gymnastic muscles are involved in creating extension of the hip and stifle during propulsion. Cc horsesinsideout
