敏捷性是一项狗在障碍赛上争夺准确性和时间的运动。参加比赛的狗必须通过大约 20 个障碍的复杂路线。我们描述了犬敏捷性生物力学的文献综述和我们的初步结果。自2010年以来，报道犬类敏捷性生物力学的文章数量逐渐增加。之前的大多数研究都集中在跳杠上，这是敏捷性的基本障碍。在我们的初步研究中，我们使用惯性传感器研究了边境牧羊犬头部和躯干的滚动运动，这些传感器完成了编织杆（狗在直线上穿过大约 10 根相距 0.6 m 的杆的障碍）。使用传感器融合算法根据角速度和线性加速度数据测量头部和躯干的侧倾角。头部和躯干几乎一致地绕滚动轴旋转。头部的侧倾幅度低于躯干的侧倾幅度。我们讨论了对犬类敏捷性进行生物力学研究的重要性，以更深入地了解哺乳动物四足运动。
Agility is a sport in which dogs compete on an obstacle course for both accuracy and time. Dogs that participate in competitions must negotiate a complex course of approximately 20 obstacles. We describe a literature review of the biomechanics of canine agility and our preliminary results. The number of articles that have reported biomechanics of canine agility has gradually increased since 2010. Most previous studies have focused on the bar jump, which is a basic obstacle to agility. In our preliminary study, we investigated the roll motion of the head and trunk using inertial sensors for Border Collies that completed weave poles (obstacles in which dogs weave through approximately 10 poles placed 0.6 m apart in a straight line). The roll angles of the head and trunk were measured based on the angular velocity and linear acceleration data using a sensor fusion algorithm. The head and trunk rotated about the roll axis nearly in unison. The roll amplitude of the head was lower than that of the trunk. We discuss the importance of biomechanical studies on canine agility to gain a deeper understanding of mammalian quadrupedal locomotion.
