Motion Streamline Evaluation of Individual Jumps Through Acceleration Variables in Show Jumping Horses

Abstract

Abstract

This study evaluates the motion streamline shape of Qatari equestrian team players through acceleration variables. Six (66.6%) of the nine players were selected, and the experiment was performed in the hall of Qatari Union of Equestrian. With the use if a camera that takes 50 pictures per second, the most important bio-automatic variables were determined to be the acceleration variables (speed/time). The performance stages were then analyzed by the program Dartfish Pro Suit 5.5. The researcher presented the data as arithmetic mean and standard deviation. The results showed that all of the participants had a range of streamline. That is, the performance of the players did not significantly change in direction. Participant 6 exhibited the best streamline because he performed the easiest landing during stages 3 and 4. Participants 1 and 5 showed great slow-down between stages 3 and 4, which affected their streamline. The streaming levels of all the participants were in the order of 6 > 4 > 3 > 2 > 5.
