Presentations and Invitations (Equestrian)
• April 4 – Gave clinic at Majestic Farm on Relative Elevation and Self Carriage (demonstration with Rosita Del Rio and instruction)
• Develop Gaited Dressage tests from USDF Intro through USEF Third Level Test Two in format with biomechanically correct icons on test fronts to assist judging.
USDF and USEF have given permission for the use of these tests. (http://www.qcdcdressage. com/QCDC/QCDCGaitedDressage.html)
• Develop web site for evaluation of training methods and tack that result in salivation as a response to bitting, bridle design and riding technique. Request from Dr. Gerd Heuschmann study group. (web address for study site available on request)
• Invited to be on board for an educational group affiliated by the Xenophon Society (http://www.xenophon-classical-riding.org/) and that sponsors clinics by Dr. Gerd Heuschmann, DVM who trained as a Bereiter (master rider) in Germany before qualifying for veterinary study at Munich University. There he specialized in equine orthopedics for two years before accepting a post as the head of the breeding department at the German Equestrian Federation, which he eventually left to start his own practice in Warendorf. He has been an active member of the “hyperflexion” (previously referred to as Rollkur) debate, weighing in at the 2005 USDF National Symposium and the 2006 FEI Veterinary and Dressage Committees’ Workshop.

Mid-South Horse Review Biomechanics for Riding

Walking in relation to piaffe (walk in place). Walk is the foundation gait and is frequently misunderstood in terms of the aids that keep its energy and beauty during all levels of training.
Rosita Del Rio (Azteca) demonstrates deep stretch in free walk to high collection in piaffe. Piaffe is a capture of the moment from walk when the foreleg is at mid stance and its diagonal pair is in braking mode. Note the soft rein contact throughout the changes in position, the soft tail, high poll, nose ahead of the vertical, allowing a comfortable performance of this high school air.. - Raab & Pancero photos.
