Effects of weight loss on heart rate normalization and increase in spontaneous activity in moderately exercised overweight dogs.

摘要: The objective of this study was to evaluate the impact weight loss on heart rate normalization at rest and during moderate exercise in overweight dogs. Spontaneous physical activity level evolution relation with also assessed. A group 15 dogs (average body condition score, BCS=7 a 9-point scale) were enrolled 3-month energy restriction protocol help them reach an ideal condition. Weight fixed 1 1.5% per week for steady healthy loss. Dogs fed management diet enriched key nutrients support function (i.e., omega-3 fatty acids from fish oil, taurine L-carnitine) assigned daily walk intensity (5 km/h) 12-week study. At completion recovered (BCS=4.3). DEXA measurement showed maintenance lean tissue 60% decrease initial fat mass. lipid metabolism observed significant blood triglycerides increase circulating free acids. Normalization observed: decreased by 17% both after only 6 weeks study, demonstrating beneficial function. Compared levels, voluntary increased 1.5 hours day following In conclusion, coupling program together standardized helped recover characterized better composition tissues expense fat. Blood parameters improved, while normalized. This highlights fact that normalizing is parameter take into consideration when treating program. Helping promoting balance between input expenditure will be useful preventing rebound.
