L’objectif de cette étude était d’évaluer les apports nutritionnels et la dépense énergétique des athlètes congolais internés et engagés au Semi-Marathon International de Brazzaville (SMIB). 40 athlètes (femmes et hommes) âgés respectivement de 22,60 ± 3,45 ans et 28,48 ± 8,18 ans, ont participé à cette étude exploratoire. La méthode du « semainier de trois jours consécutifs » pour collecter les données alimentaires et la « formule de Harris et Benedict » pour calculer la dépense énergétique des athlètes étaient utilisées. Les tables de composition alimentaires ont servi pour convertir les macronutriments. Résultats: les pourcentages des glucides (68,27% et 61,4%) étaient normaux, tandis que ceux des lipides (14,39% et 16,49%) et protéines (17,34% et 22,11%) étaient loin des recommandations. L’apport énergétique des femmes était supérieur à la dépense (3423,4 Kcal vs 2256,01 Kcal). La quantité d’énergie apportée chez les hommes était inférieure à la dépense (2980,93 Kcal vs 3181,90 Kcal). Les performances (1h 11’33’’, 1h 13’58’’ et 1h 22’27’ et 1h 15’43’’) étaient faibles. Conclusion : la balance énergétique des athlètes était déséquilibrée, avec une alimentation hyperprotéique et hypo lipidique. Cette alimentation est source de fatigue nerveuse, de mauvaise récupération et constitue un facteur limitant de la performance sportive.
The objective of this study was to evaluate the nutritional intake and energy expenditure of Congolese athletes interned and engaged in the Brazzaville International Half-Marathon (BIHM). 40 athletes (women and men) aged 22.60 ± 3.45 years and 28.48 ± 8.18 years respectively participated in this exploratory study. The “three consecutive day week planner” method of three consecutive days” to collect dietary data and the “Harris and Benedict formula” to calculate the athletes' energy expenditure were used. Food composition tables were used to determine the weight of foods and the conversion of their macronutrients. Results: the percentages of carbohydrates (68.27% and 61.4%) were normal, while those of lipids (14.39% and 16.49%) and proteins (17.34% and 22.11%) were away from recommendations. The energy intake of women was higher than the expenditure (3423.4 Kcal vs 2256.01 Kcal). The amount of energy provided in men was lower than the expenditure (2980.93 Kcal vs 3181.90 Kcal). The performances (1 h 11'33'', 1 h 13'58'' and 1 h 22'27' and 1 h 15'43'') were low. Conclusion: the energy balance of the athletes was unbalanced, with a high protein and low lipid diet. This diet is a source of nervous fatigue, poor recovery and is a limiting factor in sports performance.
Introduction:This study assesses the effects of pollutants generated by the burning of firewood by pygmies practicing the smoked meat trade. Materials and Methods: A total of 56 rural pygmies aged 36.92 ± 4.69 years old were divided into two groups, whose 29 exposed pygmies (practicing meat smoking) and 27 less exposed pygmies (not practicing this trade). Levels of PM2.5 pollutants and respiratory parameters were measured. A questionnaire including demographic data and another to identify symptoms of respiratory diseases were used. Epi info 7 software was used to perform the analyses. Results: This study indicates high concentrations of pollutants in the environment where this occupation is practiced. All spirometric parameters decreased in the exposed pygmies. The symptomatology was chronic cough, shortness of breath, wheezing and dyspnea that were higher in the exposed pygmy group. There was a strong association between the age of the subjects, the duration of exposure and the level of pollutants with certain symptoms. Conclusion: These results suggest that pygmies involved in smoking game meat inhale significant quantities of toxic particles. This pollution has health and environmental implications. Screening programmer are needed for this population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
