“…It is important to focus on the nutritional aspects of individuals submitted to physical exercise programs 13 , such as participants of metabolic and cardiopulmonary rehabilitation program (MCRP), who must keep a balanced diet for health maintenance and good physical performance 14 . Early detection and appetite loss treatment may avoid weight loss, improve health and reduce mortality 15 .…”

This study aimed to translate and validate a Brazilian version of the Simplified Nutritional Appetite Questionnaire (SNAQ), checking its clarity and validity for the participants of the Cardiopulmonary and Metabolic Rehabilitation Program (CPMR). One hundred and forty-six subjects were interviewed: 79 males, mean age of 63 years (±10) and 67 women, mean age of 66 years (±11). Descriptive analysis was presented as mean, standard deviation and frequency. The internal consistency of the scale was assessed using Cronbach's alpha coefficient and factor analysis by the method of extraction of principal components analysis using Kaiser's criteria (eigenvalues > 1). All questions of the instrument showed positive results regarding clarity. The questionnaire items presented factor loadings above 0.40, (ranging from 0.40 to 0.81). Except for the issue related to the amount of daily meals, all others showed high correlation with the total score of the Brazilian version. Regarding the analysis of internal consistency, the result of 0.61 was reached. In conclusion, the Brazilian Version of SNAQ proved to be valid for use in CPMR program participants, thus becoming an important tool in assessing the appetite of the Brazilian population.

“…It is known that an increased frequency of movement results in heat production (Moura et al, 2011). According to Carvalho and Mara (2010), the thermal energy that movement produces elevates the body temperature of the bird and causes the blood flow to be deviated to peripheral regions of the body, thereby transporting the heat to the body surface for dissipation (Macari et al, 2002).…”

Effect of chamomile extract on the welfare of laying Japanese quail

-The objective of this study was to evaluate the effect of chamomile extract on Japanese quail on their performance, animal behavior, tonic immobility, body injuries, and surface temperature. The trial was conducted using 108 quail distributed in a completely randomized experimental design, with three treatments (0, 2.5, and 5.0 g chamomile/kg of feed), six replicates, and six birds per treatment, evaluated in six measures repeated in time (14, 28, 42, 56, 70, and 84 days of trial). The inclusion of chamomile presented a quadratic effect on sitting behavior, estimating the inclusion of 1.8 g chamomile/kg to maximize this behavior. There was a decreasing linear effect for aggressive pecking, that is, the higher the inclusion of chamomile in the diet, the lower the expression of this behavior. The inclusion of 1.8-5.0 g chamomile/kg in a Japanese quail diet reduces the behavior of aggressive pecking, in addition to keeping the birds seated longer. These results are innovative because they show in the literature for the first time that chamomile supplemented in Japanese quail diets has the capacity to modulate the behavior of the quail, leading to an improvement in the welfare of quail raised in cages.

“…A progressive dehydration condition will cause a decrease in plasma volume during the exercise, leading to cardiovascular adaptation by increasing the heart rate in an attempt to maintaining sufficient cardiac output to meet the active muscles and assist in the thermoregulatory mechanism, since the venous return and consequently the systolic volume are affected 27 . In certain extreme dehydration conditions, the cardiovascular adaptation can trigger a collapse, producing a cardiac arrest 28 .…”

Introduction: To ensure performance and health, the type of food and the time of pre-exercise ingestion should be considered by practitioners of morning physical activity. Objective: This study assessed the metabolic response after pre-exercise meals with different glycemic indexes (GI) and in the fasting state adopting different types of hydration. Methods: Twelve men performed four experimental tests; two with pre-exercise meals of high GI (HGI) and low GI (LGI), and two were performed in the fasting state with hydration: water (H 2 O) and carbohydrate drink (CHO). Each test consisted of a pre-exercise rest period of 30 minutes followed by 60 minutes of cycle ergometer with continuous load equivalent to 60% of the extrapolated maximal oxygen consumption (VO 2MaxExt ). During the exercise, participants were hydrated every 15 minutes with 3mL per kg body weight. During each experimental test, venous blood samples were obtained for fasting and at 15-minute intervals during rest, and every 20 minutes during exercise. The gas analysis was carried out in periods of 5 minutes every 20 minutes of exercise. Results: There was no difference in substrate oxidation. After 20 minutes of exercise, pre-exercise food intake procedures showed similar behavior, having only reduced blood glucose levels compared to fasting procedures (p<0.01). There was maintenance of blood glucose at stable and higher levels during exercise in relation to the other tests in the fast procedure with CHO. Conclusion: The data suggest that despite the similar metabolic behavior between LGI and HGI meals, the adoption of a LGI meal before the morning exercise seems to be a more suitable feeding practice due to higher tendency of rebound hypoglycemia after HGI meal and when morning exercise is performed on fasting, hydration with CHO seems to minimize the hypoglycemic risk arising from that state.
