Abstract：
During a water treadmill (WT) exercise, horses change their accelerometric patterns. We aimed to analyze if these changes persist during terrestrial locomotion. Six horses were randomly subjected to 40 min duration WT exercises, without water (WW), at the depth of fetlock (FET), carpus (CAR) and stifle (STF), with a day off between them. Before and after 30 min after WT, horses were evaluated at walk and at trot on a track with a triaxial accelerometer fixed on the pectoral (PECT) and sacrum (SML) regions. The percent of change from baseline (before WT and after each exercise session) were calculated. Total, dorsoventral, longitudinal and mediolateral accelerometric activities and dorsoventral displacement increased with the accelerometer in PECT but decreased after WT at STF. Velocity increased with the accelerometer in PECT but decreased with the accelerometer in SML, particularly after WT at STF. A reduction in stride frequency was found with the accelerometer in PECT. SL increased with the accelerometer in SML but decreased with WT at STF. Some accelerometric changes that happened on WT remained shortly in terrestrial locomotion. The reduction in some parameters after WT at STF depth seems to indicate fatigue. This should be considered in training or rehabilitation programs for unfit animals.
摘要：
在跑步机(WT)运动中，马改变了他们的加速模式.我们旨在分析这些变化在陆地运动期间是否持续存在。六匹马随机接受了40分钟的WT锻炼，没有水（WW），在fetlock(FET)的深度，carpus(CAR)和stifle(STF)，他们之间休息一天。WT后30分钟前后,使用固定在胸肌（PECT）和骶骨（SML）区域的三轴加速度计在赛道上步行和小跑时对马进行评估。计算从基线(WT之前和每次锻炼之后)的变化百分比。总计,腹侧，在PECT中，纵向和中侧加速度活动和背腹位移随加速度计的增加而增加，但在STF的WT后下降。速度在PECT中随着加速度计的增加而增加，但在SML中随着加速度计的减少而减少，特别是在STF的WT之后。在PECT中使用加速度计发现步幅频率降低。SL在SML中随加速度计增加而增加，但在STF时随WT降低。WT上发生的一些加速度变化在陆地运动中仍然存在。在STF深度的WT之后，某些参数的减少似乎表明疲劳。这应该在不适合动物的训练或康复计划中考虑。
