Evaluation of Dietary Intakes and Supplement Use in Elite Paralympic Athletes
Notice bibliographique
Résumé
The Paralympic Games are highly competitive and athletes need to maximize performance, one crucial aspect of which is nutrition. Dietary intakes and supplement use in high‐performance, athletes with physical disabilities remain largely unexplored and specialized recommendations are lacking. Consequently, these athletes may be at risk for nutritional deficiencies and supplement misuse. The aim of this study is to assess nutritional intakes, dietary supplementation patterns, and sources of dietary supplement information in Canadian athletes with physical disabilities. Male (n=18) and female (n=22) athletes were recruited from various Paralympic sports across Canada through sporting organizations, coaches, and social media. Males had significantly greater total energy intakes than females (male=2092 kcal/day; female=1602 kcal/day, p=0.013). Males had greater protein intakes based on body weight than females (p=0.0017), while fat and carbohydrate intakes were similar in both genders. Females consumed a significantly greater percentage of their total calories from sugar as compared to males (p=0.049). Athletes' intakes met or exceeded the majority of recommended daily allowances (RDA) for vitamins and minerals, with the exception of vitamin D, vitamin E, and magnesium. Males did not meet the RDA for folate and vitamin A, while females did not meet the RDA for iron and calcium. Athletes did not meet the AI for pantothenic acid and potassium. Females had significantly lower percent of the recommendations for calcium (p=0.031), selenium (p=0.016), and iron (p<0.001) as compared to males. Supplement use is high in this population; 100% of males and 91% of females reported supplement use within the past three months. Males most regularly used sports bars, protein powder, and sport drinks, while females most regularly used vitamin D, protein powder, and fatty acids. Significant differences were noted in branched chain amino acids, as males were more likely to use this supplement (p=0.008). The top three reasons for taking supplements were “stay healthy,” “increase energy,” and “medical.” Sources of dietary supplements were reported as dietician/nutritionist, medical physician (doctor), and athletic trainer. In conclusion, elite Paralympic athletes tend to consume diets that are adequate in most macro‐ and micronutrients with a high usage of dietary supplements. Future studies should evaluate impairment levels on energy and macronutrient intakes to work towards recommendations and to adequately educate and support these athletes.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
