When engaging in regular physical activity, protein requirements increase in order to build muscle mass. It also leads to significant losses in carbohydrates, lipids, minerals, and water. These reserves must be replenished regularly. The objective of this study was to evaluate dietary habits after engaging in physical activity and sports in the city of Brazzaville. Eighty (80) men and women subjects aged between 35 and 65 participated in this study.

Nutritional status was determined using medical equipment. Eating habits were identified using a 3-day consecutive weekly food diary. The macronutrients contained in these foods were determined and the nutrients were converted after quantification using the food composition tables per 100 g of edible portion provided by the FAO.

The results show that more men than women engage in physical activity and sports for fitness. Men engage more in endurance activities, while women engage more in fitness activities. In terms of eating habits, the people surveyed consume quick meals of pork broth (73.3% of men), salted fish (38.33% of women), sugary drinks (25% of women), and alcohol (75% of men). After physical activity and sports, these subjects are welcomed in restaurants and makeshift bars. In addition, the foods consumed were rich in protein, fat, and carbohydrates. In conclusion, alcohol consumption and nutrient-rich fast food can have a detrimental effect on the health of adults who engage in physical activity and sports for maintenance.
