Rider position and balance significantly affect horse welfare through their influence on back pain, movement quality, and behavioral stress during ridden work.
Rider position is an overlooked horse welfare factor — even with a well-fitting saddle, an unbalanced or tense rider creates loading asymmetries and movement restrictions that contribute to back pain and behavioral stress. Horses with back pain from rider-related issues may show reluctance to work, cold-back behavior, and reduced performance that is attributed to training problems rather than physical discomfort. Regular assessment of rider asymmetry by a trainer with biomechanics knowledge, combined with rider physiotherapy to address underlying physical limitations, is welfare-positive management. The concept of rider fitness as a component of horse welfare — maintaining the physical condition to ride without causing harm — is gaining recognition in performance equestrian communities.
