Abstract

Objective: To assess whether running-track length (25 or 40 m) impacted the repeatability of results across runs using the Penn Vet Working Dog Center sprint test. While the 25-m track is standard, the impact of a longer track remains unknown. Determining whether a longer track improves repeatability is crucial for ensuring accurate performance assessments and optimizing protocols.

Methods: A counterbalanced crossover design compared within-subject variability between the 2 course distances (25 and 40 m). Seventeen working dogs in training participated in the study. Dogs were a minimum of 8 months old. Exclusion criteria were any canine illness or injury, adverse health events on test days, or a history of heat injury. The study took place from November 28 through December 15, 2023, in a temperature-controlled indoor space, with data collected 2 days/wk for 3 weeks.

Results: Inter-run reliability within dogs was moderate for the 25-m track (0.67; 95% CI, 0.44 to 0.79) and good for the 40-m track (0.82; 95% CI, 0.66 to 0.91). Dogs reached the 25-m line significantly faster when it was the interim point within the 40-m track compared to when it was the finish line.

Conclusions: These results corroborate previous findings that the test produces repeatable results in healthy dogs, with the novel finding that the repeatability of results is improved when the track length is 40 m.

Clinical relevance: By using this test longitudinally, veterinarians, handlers, and trainers can make data-driven decisions about a dog's readiness for sport or work, helping to prevent overtraining or injury.

跑道长度影响工作犬冲刺测试结果的重复性。
目的:利用宾夕法尼亚兽医工作犬中心的冲刺测试,评估跑道长度(25米或40米)是否会影响结果的重复性。虽然25米的轨道是标准的,但更长的轨道的影响尚不清楚。确定更长的轨道是否可以提高可重复性对于确保准确的性能评估和优化协议至关重要。方法:采用平衡交叉设计,比较2个疗程距离(25米和40米)的受试者内变异性。17只接受训练的工作犬参与了这项研究。狗至少8个月大。排除标准为任何犬类疾病或损伤、试验日不良健康事件或热损伤史。该研究于2023年11月28日至12月15日在一个温度可控的室内空间进行,每周收集2天数据,持续3周。结果:狗在25米跑道上的跑间信度中等(0.67;95% CI, 0.44至0.79),40米轨道良好(0.82;95% CI, 0.66 ~ 0.91)。当25米线是40米跑道的中间点时,狗狗到达25米线的速度明显快于终点线。结论:这些结果证实了先前的发现,即该测试在健康犬身上产生可重复的结果,并且新的发现是,当赛道长度为40 m时,结果的可重复性得到提高。临床相关性:通过纵向使用这个测试,兽医、指导师和训练师可以根据数据做出决定,了解狗是否准备好运动或工作,帮助防止过度训练或受伤。

期刊介绍: The American Journal of Veterinary Research supports the collaborative exchange of information between researchers and clinicians by publishing novel research findings that bridge the gulf between basic research and clinical practice or that help to translate laboratory research and preclinical studies to the development of clinical trials and clinical practice. The journal welcomes submission of high-quality original studies and review articles in a wide range of scientific fields, including anatomy, anesthesiology, animal welfare, behavior, epidemiology, genetics, heredity, infectious disease, molecular biology, oncology, pharmacology, pathogenic mechanisms, physiology, surgery, theriogenology, toxicology, and vaccinology. Species of interest include production animals, companion animals, equids, exotic animals, birds, reptiles, and wild and marine animals. Reports of laboratory animal studies and studies involving the use of animals as experimental models of human diseases are considered only when the study results are of demonstrable benefit to the species used in the research or to another species of veterinary interest. Other fields of interest or animals species are not necessarily excluded from consideration, but such reports must focus on novel research findings. Submitted papers must make an original and substantial contribution to the veterinary medicine knowledge base; preliminary studies are not appropriate.
