“…This observation is consistent with studies that have reported that rats generally decrease food intake in response to high intensity exercise (> 80% VO 2 max) (Katch et al 1979;Flores et al 2006). It has been suggested appetite suppression resulting from HIIT is due to a rise in epinephrine and norepinephrine levels during chronic physical training, with both neurotransmitters contributing to post-training inhibition of food intake (Guilland et al 1988). Another mechanism thought to be responsible for the reduced energy consumption D r a f t effect of physical training is the increase release of corticotropin releasing factor (CRF) by the hypothalamus, a potent anorectic peptide (Rivest & Richard 1990).…”

Physical activity has the potential to reduce cardiometabolic risk factors but evaluation of different intensities of physical activity and the mechanisms behind their health effects still need to be fully established. This study examined the effects of sedentary behaviour, light-intensity training, and high-intensity interval training on biometric indices, glucose and lipid metabolism, inflammatory and oxidative stress markers, and vascular and cardiac function in adult rats. Rats (12 weeks old) were randomly assigned to 1 of 4 groups: control (CTL; no exercise), sedentary (SED; no exercise and housed in small cages to reduce activity), light-intensity trained (LIT; four 30-min exercise bouts/day at 8 m/min separated by 2-h rest period, 5 days/week), and high-intensity interval trained (HIIT, four 2.5-min work bouts/day at 50 m/min separated by 3-min rest periods, 5 days/week). After 12 weeks of intervention, SED had greater visceral fat accumulation (p < 0.01) and slower cardiac conduction (p = 0.04) compared with the CTL group. LIT and HIIT demonstrated beneficial changes in body weight, visceral and epididymal fat weight, glucose regulation, low-density lipoprotein cholesterol, total cholesterol, and mesenteric vessel contractile response compared with the CTL group (p < 0.05). LIT had significant improvements in insulin sensitivity and cardiac conduction compared with the CTL and SED groups whilst HIIT had significant improvements in systolic blood pressure and endothelium-independent vasodilation to aorta and mesenteric artery compared with the CTL group (p < 0.05). LIT and HIIT induce health benefits by improving traditional cardiometabolic risk factors. LIT improves cardiac health while HIIT promotes improvements in vascular health.

“…In addition, VP fibres originating from the hypothalamic paraventricular nucleus, an area involved in control of VP, oxytocin and CRF secretion (Makara, 1985), regulation of food intake (Leibowitz, Hammer & Chang, 1981) and control of sympathetic outflow (Yoshimatsu, Niijima, Oomura, Yamabe & Katafuchi, 1984), project to many areas of the CNS including the autonomic centres of the brain stem and the preganglionic sympathetic neurones of the spinal cord (Eiden & Brownstein, 1981;Zimmerman et al 1984). Since food intake appears to be inversely related to sympathetic tone (Arch, Ainsworth & Cawthorne, 1982Tordoff, Hopfenbeck, Butcher & Novin, 1982Bray, 1986;Guilland, Mareau, Genet & Klepping, 1988) VP's hypophagic effect could be explained by its stimulatory effect on sympathetic outflow. The reversal of VP's inhibitory effect on feeding by the a-receptor blocker phentolamine is consistent with this assumption.…”

Vasopressin Reduces Food Intake in Goats

1989

SUMMARYThe effect of arginine vasopressin (VP) on cumulative food intake and meal pattern was tested in pygmy goats. VP injected intraperitoneally (i.P.) (0-75, 1-5 and 3 0 ,tg kg-' body weight) appeared to reduce food intake in a dose-dependent manner by reducing the size of the first meal and by increasing the first intermeal interval (IMI). The hypophagic effect of VP was reversed by both a VI-receptor antagonist and an a-adrenergic antagonist. Exogenous VP (0 75 and 1b5 ,tg kg-' body weight i.P.) produced increases in plasma VP concentration which also may occur in stressful situations. VP might therefore be related to stress-induced anorexia.

“…Interestingly, a previous study suggested that urinary norepinephrine:creatinine (NE/Cr) and epinephrine:creatinine ratios (E/Cr) do not offer valid physiological measures of acute canine stress [11]. As a metabolite of epinephrine and norepinephrine, VMA is found in much higher levels in urine than the hormones themselves [71,72] and, unlike urinary levels of epinephrine and norepinephrine [73], urinary VMA levels do not appear to be affected by exercise [74]. Thus, VMA/Cr may provide a more reliable indicator of acute psychological…”

Domestic dogs (Canis familiaris) housed in kennelling establishments are considered at risk of suffering poor welfare. Previous research supporting this hypothesis has typically used cortisol:creatinine ratios (C/Cr) to measure acute and chronic stress in kennelled dogs. However, the value of C/Cr as a welfare indicator has been questioned. This study aimed to test the validity of a range of physiological, physical and behavioural welfare indicators and to establish baseline values reflecting good dog welfare. Measurements were taken from 29 privately-owned dogs (14 males, 15 females), ranging in age and breed, in their own home and in a boarding kennel environment, following a within-subjects, counterbalanced design. Pairwise comparisons revealed that C/Cr and vanillylmandelic acid:creatinine ratios (VMA/Cr) were higher in the kennel than home environment (P=0.003; P=0.01, respectively) and were not associated with differences in movement/exercise between environments. Dogs' surface temperature was lower in kennels (P=0.001) and was not associated with ambient temperature. No association with age, or effects of kennel establishment, kennelling experience, sex or source were found. Dogs were generally more active in kennels, but showed considerable individual variability. C/Cr and 5-HIAA:creatinine ratios (5-HIAA/Cr) were negatively correlated with lip licking in kennels. Baseline values for each parameter are presented. The emotional valence of responses was ambiguous and no definitive evidence was found to suggest that dogs were negatively stressed by kennelling. It was concluded that C/Cr and, particularly, VMA/Cr and surface temperature provide robust indicators of psychological arousal in dogs, while spontaneous behaviour might be better used to facilitate interpretation of physiological and physical data on an individual level.
