A high-speed cinematographic analysis of interlimb time and linear gait characteristics was carried out at racing speed (12.0 m/sec; 1:23.6 min/km) in 30 clinically sound Standard-bred trotters. In respect of the whole group of horses the racing trot was found to be a very regular and symmetric gait. The variation coefficient between different horses ranged from 8 to 21 per cent depending on the particular characteristic being investigated. The variations recorded in individual animals were about 60 per cent less than those found for the whole group. The most stable characteristics were the duration and length of the step. Some horses exhibited striking gait asymmetries and the possible causes are considered. It is also observed that some trotters adopt a transition of gait that cannot be classified as a trot.
对30匹临床健康的标准赛马在比赛速度（12.0米/秒；1:23.6分钟/公里）下的肢体间时间和线性步态特征进行了高速电影分析。就整个马群而言，比赛快步被发现是一种非常规则和对称的步态。不同马匹之间的变异系数根据所研究的特定特征在8%至21%之间。个体动物记录的变异比整个群体发现的变异少约60%。最稳定的特征是步幅的持续时间和长度。一些马表现出明显的步态不对称，并考虑了可能的原因。还观察到一些快步马采用了一种不能归类为快步的步态转变。
