The purpose of this study was to determine basic kinematic parameters (linear, temporal and angular) in young and adult Andalusian horses (P.R.E.) at the trot, using a normal computer-aided videography system. The trotting gaits of 16 horses were analysed: seven young horses (3.7 +/- 0.2 years old, height at withers 167.1 +/- 4.1 cm) and nine adult stallions (12.3 +/- 2.9 years old, height at withers 162.9 +/- 3.6 cm) were recorded at least 6 times at the trot using a 25-Hz video-camera filming from the side. Video images were processed with a real-time digital system (SMVD). Speeds averaged 3.84 and 3.75 m/s for young and adult horses, respectively. Differences between age groups for speed and linear and temporal parameters of the stride were not significant. However, variations in angular parameters were detected: adults showed a greater ARM than younger horses for most forelimb joints. In the hind limb, hip, stifle, and, to a lesser degree, the tarsal joint, a smaller degree of extension during the stance phase was observed in adult horses.
本研究的目的是使用普通的计算机辅助摄像系统，测定安达卢西亚幼马和成年马（西班牙纯种马）在小跑时的基本运动学参数（线性、时间和角度参数）。分析了16匹马的小跑步态：7匹幼马（3.7±0.2岁，肩高167.1±4.1厘米）和9匹成年种马（12.3±2.9岁，肩高162.9±3.6厘米），使用25赫兹的摄像机从侧面拍摄，每匹马的小跑至少记录6次。视频图像通过实时数字系统（SMVD）进行处理。幼马和成年马的平均速度分别为3.84米/秒和3.75米/秒。年龄组之间在速度以及步幅的线性和时间参数方面的差异不显著。然而，检测到角度参数存在变化：对于大多数前肢关节，成年马的臂运动幅度（ARM）比幼马更大。在 hind limb（此处原文可能有误，推测为“后肢”），成年马在站立期髋关节、膝关节以及跗关节（程度较轻）的伸展程度较小。
