“…The dogs were exposed to a daily morning training routine and housed under standard husbandry conditions, thus avoiding temperature extremes throughout the study. No differences in the measured oxidative stress parameters were observed between males and females before and after exercise, which is in accordance to the data published by Ilhan et al [8] for athletes of both sexes exposed to aerobic-anaerobic exercise.…”

“…The so formed oxidative modifi cations of plasma constituents are an expression of oxidative damage that occurred in the tissues during exercise [6]. Kanter et al [7] reported that peroxidation products were observed in the blood of athletes after extreme exercise and further studies by Ilhan et al [8] disclosed differences due to type of exercise to which the athletes were exposed. However, the results of studies that addressed the question whether exercise induced oxidative stress are still not consistent, probably due to the different levels of training, environmental conditions, dietary regimens, timing of sampling, etc.…”

The aim of this study was to evaluate the effects of 60 days of rose-hip and grapeseed dietary supplementation of a balanced home-cooked diet on serum oxidative stress parameters: ROMs, MDA and FRAP in army service dogs before and after regular physical exercise. The dogs were fed a balanced cooked diet as instructed by army standards until the initial blood sampling in June. Thereon the dogs were randomly allotted to 4 groups according to the dietary regime: dogs maintained on a balanced cooked diet according to army standards, branded dry dog food, cooked diet with added 500 mg rose-hip extract, and cooked diet with added 100 mg grapeseed extract for a 60 day period from June to September after which all 4 groups were fed the standard cooked meal diet. Sampling was performed at the beginning of the experiment (June), 60 days from the start of the treatment (September) and finally 60 days after the end of supplementation (November). Statistical analysis of the results included descriptive statistical parameters: mean (M), standard deviation (SD), and variation coefficient (CV%). In order to test the statistical significance of the differences between treatments a multifactor variance test (ANOVA) was performed for ROM, MDA and FRAP and the combined effects of diet, exercise and time period were observed. The initial (in June) increase in MDA and ROMs after exercise indicates the presence of oxidative stress 30 minutes after exercise. However, the antioxidative effects of rose-hip and grapeseed extracts are not conclusive, as multifactor ANOVA testing of time, diet, and exercise factors did not reveal for MDA statistically significant differences either at 60 days of supplementation nor 60 days after withdrawal of the supplements. Only one distinct exception was recorded for the prolonged antioxidative effects reflected in significantly decreased (p<0.01) ROMs before and after exercise in dogs fed the branded dry food 60 days after the end of such dietary regime (November). FRAP values tend to be higher (p>0.05) after exercise compared to before exercise in all experimental groups in November, indicating on a possible redistribution and upregulation of endogenous antioxidants during the experiment.

“…Os ácidos graxos livres na circulação aumentam durante o exercício devido à mobilização dos estoques de lipídios, ao mesmo tempo em que os estoques de glicogênio diminuem (ILhAN et al, 2004), mas exatamente como o exercício exerce suas ações benéficas prevenindo o risco de doenças cardiovasculares é desconhecido (MEISSNER et al, 2010). De fato, os mecanismos que estão envolvidos por trás de como os exercícios induzem melhoras no perfil lipídico não tem sido definido (MEISSNER et al, 2010).…”

“…Moreover, sedentary behavior is an important risk factor for chronic disease morbidity and mortality with aging [3]. To understand how exercise affects the mortality risk from lifestyle-related diseases, the impact of exercise on several biological markers related to glucose and lipid metabolisms has been examined in humans [4][5][6][7]. Different forms of exercise, aerobic or anaerobic, voluntary or forced, and differences in the manner, duration, and amount can be expected to have different effects on biological markers in human and rodent models [4][5][6][7][8][9].…”

Different forms of exercise, aerobic or anaerobic, voluntary or forced, and differences in the manner, duration, and amount can be expected to have different effects on biological markers in human and rodent models [4][5][6][7][8][9]. For the prevention of lifestyle-related diseases, such as obesity and diabetes, the Centers for Disease Control and Prevention and the American College of Sports Medicine have jointly published recommendations that adults should engage in at least 30 min of moderate physical activity (e.g., brisk walking) on most, and preferably all, days of the week [3,10]; therefore, the impact of exercise (long-term, moderate physical activity, aerobic, and voluntary), namely, habitual exercise, on biological markers should be analyzed in detail.…”

Objectives To determine the impact of long-term voluntary exercise, representing habitual exercise for the prevention of lifestyle-related diseases, on glucose, lipid, and amino acid metabolism in mice. Methods Twenty-four mice aged 6 weeks were divided into three groups. Two groups (16 mice) were housed individually in either cages equipped with a running wheel (8 mice, exercising, Ex-mice) or without (8 mice, sedentary, Se-mice) for 24 weeks. The remaining group (8 mice) was sacrificed at 6 weeks of age. Biomarkers related to glucose, lipid, and amino acid metabolism were examined.Results Ex-mice ran voluntarily, predominantly in the dark. The distance per day peaked at 4 weeks and then decreased until 12 weeks to around the level seen at the beginning of the experimental period, and was maintained at 4.9 ± 0.2 km/day from 12 to 24 weeks. Ex-mice showed a similar adrenal weight and vitamin C content to Se-mice but had a significantly lower body weight and higher food intake. Ex-mice also showed a higher skeletal muscle weight, a lower white adipose tissue and liver weight, associated with lower plasma leptin and insulin-like growth factor-1 levels, and a lower hepatic triglyceride content. Analysis of plasma amino acids showed that Ex-mice had significantly higher phenylalanine, tyrosine, and glutamine levels, resulting in a significantly lower Fischer's ratio. Conclusions We present an animal model of long-term voluntary exercise under low stress. Findings related to the effects of long-term voluntary exercise on lipid, and amino acid metabolism in our mouse model indicate that such an exercise regimen may affect pathophysiological states related to appetite and behavior.
