“…In this perspective, their answer, therefore, justifies our main hypothesis which states "The Congolese athletes of the Brazzaville departmental athletics league do not have any real knowledge of sports nutrition" (Table 9). Athletes must consume foods rich in macronutrients, such as carbohydrates, proteins and fats which are energy elements and constitute the fuel necessary for a living organism and practicing physical activities (Braun et al, 2019). These results agree with the recommendations of Economos et al (1993) in athletes and coaches.…”

“…Following the advantages of nutritional knowledge, the work of Kwon et al ( 2020) and Okano et al (2021) suggested that energy intake should be distributed as follows: 50 to 55% of carbohydrates, 30 to 35% of lipids and 10 to 15% of protein. Despite extensive research on athletes, it is established that diet is adapted according to the type of sport practiced and the nutritional needs of the athlete (Papadopoulou et al, 2022;Braun et al, 2019;Lis et al, 2019). This requires the necessary knowledge related to nutrition (Scalvedi et al, 2021;Ozdoğan et al, 2011).…”

The place of a balanced diet in sport has proven to be very important. The objective of this study was to assess the nutritional knowledge of athletes in the Brazzaville athletics league. Our study was conducted on a sample of 50 athletes including 29 Boys and 21 Girls from the events combined with an average age of 23.50 ± 3.32 years and 21.33 ± 9.41 years respectively. The method used was the Abbreviated Sports Nutrition Knowledge Questionnaire (ANSKQ) to collect data related to nutrition knowledge from athletes. The results showed ignorance of ranking products for carbohydrate, fat, and protein gain respectively by 62.06% of Boys and 47.61% of Girls, 51.72% of Boys 80.95% of Girls, and 51 72% of Boys versus 61.90% of Girls). Similarly, 51.72% of Boys and 52.38% of Girls ignored the percentages of a balanced diet. Knowledge of what to eat to perform was low in 62.06% of boys and 66.66% of girls. The type of ration established was based on traditional experience in 65.51% of boys and 42.85% of girls. The level of nutrition knowledge was low in 51.72% of boys and 52.38% of girls. This justified the non-respect of meal intake and meal times before sport practice respectively in 82.75% of boys and 95.23% of girls. Hence the non-participation in the composition of the menus of 100% of Boys and 100% of Girls. In conclusion, Congolese athletes have a very low level of knowledge in the field of nutrition. However, a low level of knowledge in nutrition is associated with a negative impact on sport performance.La place de l’alimentation équilibrée dans le domaine sportif est avérée très importante. L’objectif de cette étude était d’évaluer les connaissances en nutrition des athlètes de la ligue d’athlétisme de Brazzaville. Notre étude a été menée sur un échantillon de 50 athlètes dont 29 Garçons et 21 Filles des épreuves confondues avec un âge moyen respectivement de 23,50 ±3,32 ans et 21,33 ±9,41 ans. La méthode utilisée était le Questionnaire Abrégé sur la Connaissance en Nutrition Sportive (ANSKQ) afin de collecter les données liées aux connaissances en nutrition auprès des athlètes. Les résultats ont montré l’ignorance de classer les produits pour le gain glucidique, lipidique et protéique respectivement par 62, 06% des Garçons et 47,61% des Filles, 51,72 % des Garçons 80,95% des Filles, et 51,72% des Garçons versus 61,90% des Filles). De même, 51,72% des Garçons et 52,38% des Filles ont ignoré les pourcentages d’une alimentation équilibrée. La connaissance de ce qu’il faut manger pour performer était faible chez 62,06% des Garçons et 66,66% des filles. Le type de ration établie était basé sur l’expérience traditionnelle chez 65,51% des Garçons et 42,85% des Filles. Le niveau de connaissance en nutrition était faible chez 51,72% des Garçons et 52,38% des Filles. Ce qui a justifié le non-respect des prises des repas et des heures repas avant la pratique sportive respectivement chez 82,75% des Garçons et 95,23% des Filles. D’où la non-participation à la composition des menus de 100% des Garçons et 100%des Filles. En conclusion, les athlètes congolais ont un niveau de connaissance très bas dans le domaine de nutrition. Or, le faible niveau de connaissance en nutrition est associé à un impact négatif sur la performance sportive. Article visualizations:<img src="/-counters-/soc/0022/a.php" alt="Hit counter" />

“…The respective metabolic equivalent (MET) intensity levels of each reported daily life physical activity were calculated and classified as light (<3 METs), moderate (3–6 METs), or vigorous (>6 METs), as suggested by Ainsworth et al [ 40 ], and subsequently, the daily physical activity level (PAL) was estimated using the average MET score over 24 h. Based on the estimated PAL values and individual anthropometric data, participants were given individual nutritional recommendations to maintain a constant daily diet during the study period. The nutritional recommendations were based on the guidelines of the German Nutrition Society (DGE) [ 41 , 42 ]. In brief, resting metabolic expenditure (REE) was calculated according to the Harris and Benedict formula [ 43 ], as follows: Men: REE (kcal/day) = 66.5 + 13.8 × weight (kg) + 5.0 × size (cm) − 6.8 × age (years) Women: REE (kcal/day) = 655 + 9.6 × weight (kg) + 1.8 × size (cm) − 4.7 × age (years) …”

Protein Supplementation Does Not Maximize Adaptations to Low-Volume High-Intensity Interval Training in Sedentary, Healthy Adults: A Placebo-Controlled Double-Blind Randomized Study

There is ample evidence that specific nutritional strategies can enhance adaptions to resistance and endurance training. However, it is still unclear whether post-session protein supplementation may increase the effects of low-volume high-intensity interval training (LOW-HIIT). We examined the impact of LOW-HIIT combined with protein vs. placebo supplementation on cardiometabolic health indices in sedentary healthy individuals. Forty-seven participants (31.1 ± 8.0 yrs) performed cycle ergometer LOW-HIIT (5–10x1 min at 80–95% maximum heart rate) for eight weeks and randomly received double-blinded 40 g of whey protein (PRO-HIIT, N = 24) or an isocaloric placebo (maltodextrin, PLA-HIIT, N = 23) after each session. The maximum oxygen uptake (VO2max, primary outcome) and several secondary cardiometabolic outcomes were determined pre-/post-intervention. VO2max increased in PRO-HIIT (+2.8 mL/kg/min, p = 0.003) and PLA-HIIT (+3.5 mL/kg/min, p < 0.001). Systolic and diastolic blood pressure decreased in PRO-HIIT (−7/3 mmHg, p < 0.05) and PLA-HIIT (−8/5 mmHg, p < 0.001). Gamma glutamyl transferase (−2 U/L, p = 0.003) decreased in PRO-HIIT and alanine aminotransferase (−3 U/L, p = 0.014) in PLA-HIIT. There were no significant between-group differences in any of the outcome changes. In conclusion, LOW-HIIT improved VO2max and other cardiometabolic markers irrespective of the supplementation condition. Post-session protein supplementation does not seem to provide any additional benefit to LOW-HIIT in improving cardiometabolic health in sedentary healthy individuals.

“…Bei intensiven Belastungen ist der Körper daher vermehrt auf die Verfügbarkeit von Kohlenhydraten angewiesen. Je höher der Ausgangswert an gespeicherten Kohlenhydraten (Glykogen) ist, umso länger kann eine Aktivität mit hoher Intensität durchgeführt werden – eine wichtige Stellschraube für den sportlichen Erfolg 2 3 .…”

So breit gefächert wie die Sportarten sind bei Sportlern auch die Bedürfnisse in puncto Ernährung. Eine ausgewogene und gesunde Ernährung unterstützt Freizeitsportler dabei, ihre individuelle Leistung und Regeneration zu verbessern. Und Hochleistungssportlern kann eine ausgeklügelte Ernährungsstrategie zu einer herausragenden Leistung verhelfen.
