摘要:

【目的】测定障碍马80 cm高度越障性能,研究其静态肢体角度和4个阶段步态特征之间的相关性,筛选出与越障性能相关的肢体角度指标,为障碍马体型结构研究提供理论依据。【方法】使用高速摄像机拍摄20匹障碍马静态肢体角度和越障时步态特征。并借助Kinovea视频分析软件提取马匹静态肢体角度和四个时期步态特征数据,分析肢体角度和步态特征的关联性。【结果】在起跳阶段时,头俯仰角和后位后蹄支撑相关系数为0.495,即呈显著正相关(P<0.05),与起跳位置呈显著负相关(P<0.05)。在悬空阶段时,后球关节和前位后蹄摆动相相关系数为0.564**,即呈极显著正相关(P<0.01)。头俯仰角和跳跃距离呈显著负相关(P<0.05)。在着陆阶段时,后飞节和前肢双支撑相呈显著正相关(P<0.05)。后球关节和前肢双支撑相相关系数为0.568,即呈极显著正相关(P<0.01)。在缓冲阶段,前球关节和步频呈显著正相关(P<0.05)。股骨倾角和后位前蹄摆动相呈显著正相关(P<0.05)。膝关节和腾空期步幅呈显著正相关(P<0.05)。头俯仰角和前位前蹄摆动相相关系数为0.570**,即呈极显著正相关(P<0.01)。【结论】在80 cm越障过程中,障碍马头俯仰角变异系数为14.59%对起跳阶段,悬空阶段、缓冲阶段有显著影响。髋骨倾角变异系数为20.22%对起跳阶段和着陆阶段有显著影响。后球关节角变异系数为3.83%对悬空阶段和着陆阶段有显著影响。头俯仰角、髋骨倾角、后球关节角等关节角度可作为重要的障碍马体型结构指标,用于评估马匹的越障性能。

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.
