Abstract：
Equine water treadmills (WT) were initially designed for rehabilitation of musculoskeletal injuries, but are also commonly used for conditioning sport horses, however the effects are not well documented. The purpose of this study was to test the effect of an 18-day WT conditioning programme on peak oxygen consumption (V̇O2peak). Nine unfit Thoroughbreds were used in a randomised controlled trial. Six horses worked daily for 18 days in stifle-height water (WT group), while 3 control horses worked without water (dry treadmill group (DT)). Preconditioning and postconditioning maximal exercise racetrack tests (800 m) were performed using a portable ergospirometry system. Measured outcomes were V̇O2, tidal volume, minute ventilation, breathing frequency, heart rate, blood lactate and instantaneous and average speed. The workload as assessed by V̇O2 was 21.7 per cent of preconditioning V̇O2peak values for WT horses. V̇O2peak on the racetrack increased by 16.1 per cent from preconditioning to postconditioning in the WT horses (P=0.03), but did not change in the DT horses. Therefore, exercising horses in high water heights may improve conditioning.
摘要：
马水跑步机（WT）最初设计用于肌肉骨骼损伤的康复，但也常用于调理运动马，然而，这些影响并没有得到很好的记录。这项研究的目的是测试18天的WT调节程序对峰值耗氧量（VO2峰值）的影响。在一项随机对照试验中使用了9种不适合的纯种犬。六匹马每天在窒息高度的水中工作18天（WT组），而3匹对照马在没有水的情况下工作（干跑步机组（DT））。预处理和后处理最大运动跑道测试（800m）使用便携式人体力量学系统进行。测量结果为V²O2，潮气量，分钟通风,呼吸频率,心率,血乳酸和瞬时和平均速度。用维生素O2评估的工作量是WT马预处理维生素O2峰值的21.7%。在WT马匹中，从预处理到后处理，赛道上的VO2峰增加了16.1％（P=0.03），但是DT马没有改变。因此,在高水位下锻炼马可以改善空调。
