Abstract

BACKGROUND

Research on the effects of physical exercise on canine body composition is limited. The aim of this study was to investigate the effects of a physical exercise programme on bodyweight, body condition score (BCS) and chest, abdominal and thigh circumferences in dogs. Twenty-one healthy dogs of different breeds exercised together with their owners during an eight-week programme consisting of jogging and strength exercises. Standardised measurements were performed in triplicates with a measuring tape on standing dogs. Chest circumference was measured at three anatomical locations, abdomen at two and thigh at one. Data on bodyweight, BCS (9-point scale) and circumferences were analysed with mixed model repeated measures analyses to evaluate changes after the programme and effects of target distance.

RESULTS

Seven dog owners choose a target distance of 2 km and 14 owners choose 5-10 km. Mean BCS decreased (P = 0.007) after the programme (5.1 ± 0.9 vs. 4.7 ± 0.6) but there was no effect of target distance. Almost all chest and abdominal circumference measurements decreased (P ≤ 0.007) with the 2 km group driving the reduction in chest circumference and the 5-10 km group driving the reduction in abdominal circumference. In contrast, thigh circumference (28.8 ± 0.4 vs. 30.2 ± 0.4) increased (P = 0.007) while bodyweight was maintained. There were positive correlations between BCS and abdominal/chest ratios before and after the programme (Pearson correlation; R square ≤ 0.43, P ≤ 0.0012) but the mean ratio remained constant.

CONCLUSIONS

Results indicated a redistribution between total body fat and muscle mass in body composition of normal weight to slightly overweight dogs after the physical exercise programme. The use of bodyweight alone was not a reliable evaluation method to complement the BCS assessment. However, repeated measurements of chest, abdominal and thigh circumference might aid in the assessment of body composition in dogs performing physical exercise. Further research should include a control group and objective evaluations of total body fat and lean mass, in order to investigate the effectiveness of physical exercise as a freestanding method for decreasing BCS and increasing muscle mass in overweight dogs.

摘要

背景

关于运动对犬体成分影响的研究有限。本研究旨在探讨运动方案对犬体重、体况评分（BCS）以及胸、腹和大腿周长的影响。21 只不同品种的健康犬与主人一起参加了为期八周的运动方案，包括慢跑和力量训练。使用卷尺在站立的犬身上进行了三次重复的标准测量。胸围在三个解剖部位进行测量，腹部在两个部位，大腿在一个部位。使用混合模型重复测量分析对体重、BCS（9 分制）和周长数据进行分析，以评估方案后的变化和目标距离的影响。

结果

7 位犬主人选择 2 公里的目标距离，14 位犬主人选择 5-10 公里的目标距离。方案后 BCS 降低（P=0.007）（5.1±0.9 与 4.7±0.6），但目标距离无影响。几乎所有的胸围和腹围测量值都减小（P≤0.007），2 公里组驱动胸围减小，5-10 公里组驱动腹围减小。相比之下，大腿周长（28.8±0.4 与 30.2±0.4）增加（P=0.007），而体重保持不变。方案前后 BCS 与腹/胸比之间存在正相关（皮尔逊相关；R 平方≤0.43，P≤0.0012），但平均比值保持不变。

结论

结果表明，在运动方案后，正常体重至轻度超重犬的体成分中，总体脂和肌肉质量发生了再分布。单独使用体重不是评估 BCS 补充评估的可靠方法。然而，反复测量胸、腹和大腿周长可能有助于评估进行运动的犬的体成分。为了研究运动作为降低超重犬 BCS 和增加肌肉质量的独立方法的有效性，应进一步开展包括对照组和总体脂肪和瘦体重的客观评估的研究。
