摘要

背景:高强度间歇训练(HIIT)由于其生理刺激更大,是一种比中等强度连续训练(MICT)更有效的提高运动能力的方法。目的:本方案的目的是评估HIIT与MICT相比对狗最大有氧能力的影响。方法:本方案是一项随机、盲法对照临床试验,为了证明优越性,有三个平行组。30只年龄在12至84个月之间的男女不同品种的狗将被包括在内。在训练开始前和结束后,狗将在跑步机上进行增量运动测试,以获得最大速度和乳酸阈值;测量心率、呼吸频率、左心室和收缩功能的静息参数。被分配到每个干预组的狗将在12周内接受42分钟的HIIT或MICT训练。HIIT包括4次间歇,每次4分钟,负荷为85%,与4分钟休息时间交替进行。MICT组的连续负荷为60%。对照组将被关在笼子里。将实施意向治疗统计分析。将使用协方差分析来评估HIIT与MICT训练在最大有氧能力、有氧阻力、静息时收缩功能、左心室测量和指标、呼吸频率和静息时心率方面的影响。结论:投入大量时间和精力训练运动犬/工作犬,可以通过HIIT方法提高身体能力。

Efficacy of high-intensity interval training compared with moderate-intensity continuous training on maximal aerobic potency in dogs: Trial protocol for a randomised controlled clinical study.

Background: High-intensity interval training (HIIT) is a more efficient method to improve exercise capacity than moderate-intensity continuous training (MICT) because of its greater physiological stimulus.

Objective: The aim of this protocol is to evaluate the efficacy of HIIT on maximal aerobic potency in dogs as compared to MICT.

Methods: This protocol is for a randomised, blinded controlled clinical trial, with three parallel groups for the purpose of demonstrating superiority. Thirty dogs aged between 12 and 84 months of both sexes and different breeds will be included. Dogs, before initiating and after finalising the training will perform an incremental exercise test on a treadmill to obtain maximal speed and lactate threshold; resting parameters of heart and respiratory rate, left ventricle chamber and systolic function will be measured. Dogs assigned to each intervention will endure a 42-min session of HIIT or MICT during 12 weeks. HIIT comprises four intervals of 4 min each at a load of 85%, alternating with a 4-min resting period. MICT group will have a continuous load of 60%. The control group will remain in a cage. An intention-to-treat statistical analysis will be implemented. Analysis of covariance will be used to estimate the effect of HIIT compared with MICT training on maximal aerobic potency, aerobic resistance, systolic function at rest, left ventricle chamber measurements and indexes, respiratory rate and HR at rest.

Conclusion: Significant time and effort are invested into training sports/working dogs, which could benefit from improving physical capacity by means of the HIIT methodology.
