- Abstract
【Objective】 To explore the correlation between static limb angle and four stages' gait characteristics by measuring the obstacle climbing performance of the obstacle horse at 80 cm height, and screen out the limb angle indexes related to obstacle climbing performance were in the hope of providing theoretical basis for the study of the body structure of the obstacle horse.【Methods】 The static limb angles and gait characteristics of 20 obstacle horses were recorded by high speed camera. Kinovea video analysis software was used to extract static limb angle and gait characteristic data of four stages, and after that, the correlation between limb angle and gait characteristic was analyzed.【Results】 At the take-off stage, the head pitch angle was significantly positively correlated with the rear hoof support phase (P< 0.05), and significantly negatively correlated with the take-off position (P< 0.05). In the hanging stage, there was a significant positive correlation between the posterior ball joint and the anterior posterior hoof swing phase (P< 0.01). There was a significant negative correlation between head pitch angle and jump distance (P < 0.05). In the landing stage, there was a significant positive correlation between the hind hock and the forelimb double support phase (P < 0.05). There was a significant positive correlation between the posterior ball joint and the bistrut phase of the forelimb (P< 0.01). In the buffering stage, there was a significant positive correlation between foreball joint and stride frequency (P< 0.05). There was a significant positive correlation between the angle of femur and the posterior anterior hoof swing phase (P< 0.05). There was a significant positive correlation between knee joint and stride length in the flight period (P < 0.05). There was a significant positive correlation between head pitch angle and forefoot swing phase (P< 0.01).【Conclusion】 In the 80 cm obstacle jumping process, the pitch angle of obstacle horse's head has significant influence on the take-off stage, hanging stage and buffering stage. The hip angle has a significant effect on the take-off and landing stages. The angle of the rear ball joint has significant influence on the hover stage and the landing stage. Joint angles, such as head pitch angle, hip angle and posterior ball angle, can be used as important body structure indexes to evaluate the obstacle climbing performance of horses.
