Study on Girth tensions

Muscles under the saddle and girth are responsible for locomotion. Impingement on these muscles by a tight girth may result in alterations to locomotion.
  • Actual girth tension varies from the intended girth tension while standing and during locomotion.
  • It is possible to obtain actual standing tensions closer to intended tensions with the application of a cam buckle, resulting in more accurate applied tensions.
  • The tension of the girth varies during locomotion, generally decreasing from standing to walk, and then increasing from walk to trot and increasing further from trot to canter.
  • Pressure distribution under saddle increased with each gait, & with increasing speed.
  • Implications on conditioning regimes. Real discomfort = decreased performance.  Not necessarily laziness.
