| description | The aim of this study was to determine the basic movements of the riders' pelvis and upper body when riding in trot seated. The study was preformed at a treadmill with seven high level dressage horses and their riders. The movements of the horse and rider were captured with a motion analysis system (ProReflex®) and also recorded on video. The horses were ridden in collected trot, 3.0 m/s. An experienced dressage teacher evaluated the video recording of the horses and riders. The rotation of the saddles and riders are measured in three directions: rotation around the x-axis, (roll), rotation around the y-axis (pitch) and rotation around the z-axis (yaw).
The pelvis of the rider is lowered on the left side during the stance phase of the left diagonal and on the right side on the stance phase of the right diagonal. The rotation of the upper body was asymmetric in the stance phase of the left diagonal for three of the riders. The saddles pitching movement is in accordance with the trunk of the horse. When the withers of the horse are at the lowest position, the saddle is most rotated forward. When the withers are at the highest position at midstance, the saddle is rotated backwards at the most. The pelvis of the rider is rotated backward at the beginning of the stance phase. It rotates forward until the second half of the stance phase and then backwards until the beginning of stance phase of the next diagonal. The upper body of the rider rotates backward during the first half of the stance phase and forward during the second phase and the swing phase. The rider and the saddle rotate to the left during the stance phase of the left diagonal and to the right during the stance phase of the right. The average score for the seat of the riders were 6 when they were evaluated by a dressage teacher. The asymmetries that were seen in the measurements could not be detected on video.
The results indicate that the pitching of the rider is a passive movement with purpose to reduce the impact when the horse lands on the ground. Correlations were seen between the roll and yaw of the pelvis, when the pelvis was lowered on one side it was also drawn back on the same side. The evaluation of the video shows the importance of combining modern techniques with the skills of people with long experience of evaluation of riders and horses to get the best results of research. |

Syftet med denna studie var att undersöka vilka grundläggande rörelser ryttarens bäcken och överliv gör vid ridning i trav vid nedsittning. Försöket utfördes på rullmatta med sju välutbildade dressyrhästar med respektive ryttare. Hästarnas och ryttarnas rörelser registrerades med ett rörelseanalyssystem (ProReflex®) och ekipagen videofilmades även. Hästarna reds i samlad trav, 3,0 m/s. En erfaren dressyrlärare utvärderade videoinspelningen av ekipagen. Rotationen av ryttarnas bäcken och överliv samt sadeln beräknades och vissa jämförelser med hästens rörelser gjordes. Rotationen mättes i tre riktningar: rotation runt x-axeln (roll), rotation runt y-axeln (pitch) och rotation runt z-axeln (yaw). Ryttarens bäcken sänks på vänster sida under vänster diagonals understöd och på höger sida under höger diagonal. Sadeln roterar runt y-axeln i takt med hästens bål. Då hästens manke är som lägst, i samband med starten av understödet för respektive diagonal, är sadeln som mest roterad framåt. Då hästens manke är som högst, under mitten av understödsfasen, är sadeln som mest roterad bakåt. Fasförskjutningar och asymmetrier i hästens rörelser ses även i sadelns rotation. Ryttarens bäcken är som mest roterat bakåt i pitch 5-10 % in i steget. Det roterar sedan framåt till andra halvan av understödet för att sedan rotera bakåt till början av nästa diagonals understöd. Överlivet roterar bakåt under den första halvan av understödet och roterar framåt under den andra halvan och under svävmomentet. Ryttaren och sadeln roterar till vänster i yaw under vänster diagonals understöd och roterar till höger under höger diagonal. Ryttarna fick medelbetyget 6 för sitsen när videoinspelningen utvärderades. De asymmetrier som sågs i mätningarna kunde inte uppfattas på video. Ryttarens pitch verkade vara en passiv rörelse med syfte att dämpa stöten då hästen landar. Det sågs samband mellan bäckenets roll och yaw, då ena höften sänks vrids den även bakåt. Genom att kombinera tekniska hjälpmedel med personer med lång praktisk erfarenhet av att granska ekipage nås den bästa utvärderingen av ryttare och häst.
