反复暴露于跑步机(WT)运动可能会引起运动学反应,反映出对WT运动的适应。该研究的目的是比较一组运动马对在三个时间点进行的标准化WT运动测试(WTSET)的反应,第0周(n=48),第20周(n=38),第40周(n=29),在纳入WT锻炼的正常培训计划中。为此,从两个商业跑步机场地的现有客户群体中招募了马,观察性研究。四肢,回来,投票,枯萎,在WTSET期间使用摄像测量骨盆运动学,光学运动捕捉,和惯性运动传感器。前肢和后肢牵引增加(两者p<0.001),与第0周相比,第40周的前肢和后肢回缩降低(两者p<0.001)。与第0周相比,第40周时的腰胸屈伸和侧向弯曲运动范围更大(分别为p<0.001和p=0.009)。训练速度的增加与头尾移动的增加有关(p=0.021),前肢牵伸减少(p=0.008),前肢回缩增加(p=0.021)。除了由于水深增加而导致的运动学特征变化之外,定期进行WT运动可使运动适应水中的运动。诸如WT会话的频率和在深度和速度方面使用的会话类型之类的因素被视为影响自适应的性质。结果表明,在正常的运动马训练计划中使用时,可以根据特定的训练目标设计WT锻炼课程。
Repeated exposure to water treadmill (WT) exercise could elicit kinematic responses reflecting adaptation to WT exercise. The
study\'s aim was to compare the responses of a group of sport horses to a standardised WT exercise test (WTSET) carried out at three time points, week 0 (n = 48), week 20 (n = 38), and week 40 (n = 29), throughout a normal training programme incorporating WT exercise. Horses were recruited from the existing client populations of two commercial water treadmill venues for the purpose of this longitudinal, observational
study. Limb, back, poll, wither, and pelvic kinematics were measured during the WTSET using videography, optical motion capture, and inertial motion sensors. Forelimb and hindlimb protraction increased (p < 0.001 for both), and forelimb and hindlimb retraction decreased (p < 0.001 for both) at week 40 compared to week 0. Caudal thoracic flexion-extension and lateral bend ranges of movement were greater at week 40 compared to week 0 (p < 0.001 and p = 0.009, respectively). Increased training speed was associated with increased craniocaudal poll movement (p = 0.021), decreased forelimb protraction (p = 0.008), and increased forelimb retraction (p = 0.021). In addition to characteristic changes in kinematics due to increasing water depth, regular WT exercise resulted in kinematic adaptation to movement in water. Factors such as the frequency of WT sessions and the type of session used with respect to depth and speed were seen to influence the nature of the adaptation. The results suggest that WT exercise sessions could be designed in accordance with specific training goals when used within a normal sport horse training programme.
