- Portuguese Football Federation consensus statement 2020: nutrition and performance in footballPublication . Abreu, Rodrigo; Figueiredo, Pedro; Beckert, Paulo; Marques, José P.; Amorim, Samuel; Caetano, Carlos; Carvalho, Pedro; Sá, Carla; Cotovio, Ricardo; Cruz, Joana; Dias, Tiago; Fernandes, Gonçalo; Goncalves, Elton; Leão, César; Leitão, Alexandre; Lopes, João; Machado, Eduardo; Neves, Mónica; Oliveira, André; Pereira, Ana I.; Pereira, Bruno; Ribeiro, Fernando; Silva, Luís M.; Sousa, Filipe; Tinoco, Tânia; Teixeira, Vitor H.; Sousa, Mónica; Brito, JoãoNutrition is an undeniable part of promoting health and performance among football (soccer) players. Nevertheless, nutritional strategies adopted in elite football can vary significantly depending on culture, habit and practical constraints and might not always be supported by scientific evidence. Therefore, a group of 28 Portuguese experts on sports nutrition, sports science and sports medicine sought to discuss current practices in the elite football landscape and review the existing evidence on nutritional strategies to be applied when supporting football players. Starting from understanding football's physical and physiological demands, five different moments were identified: preparing to play, match-day, recovery after matches, between matches and during injury or rehabilitation periods. When applicable, specificities of nutritional support to young athletes and female players were also addressed. The result is a set of practical recommendations that gathered consensus among involved experts, highlighting carbohydrates periodisation, hydration and conscious use of dietary supplements.
- Endocrine disruptor DDE associated with a high-fat diet enhances the impairment of liver fatty acid composition in ratsPublication . Rodríguez-Alcalá, Luis M.; Sá, Carla; Pimentel, Lígia L.; Pestana, Diogo; Teixeira, Diana; Faria, Ana; Calhau, Conceição; Gomes, Ana M. P.The banned pesticide dichlorodiphenyltrichloroethane (DDT) and its main metabolite, p,p′-dichlorodiphenyldichloroethylene (DDE), are commonly found in the food chain and in all tissues of living organisms. DDE is associated with metabolic diseases acting as an endocrine disruptor and more recently with the obesity pandemic. This study focuses on using fatty acid analysis to relate DDE exposure and metabolic dysfunction: liver and adipose tissue (visceral and subcutaneous) composition from male Wistar rats fed a standard (STD) or high-fat (HF) diet versus the addition of DDE in water. DDE exposure increased liver levels of palmitic, stearic, oleic, trans fatty, and linoleic acids having altered the n6 and n3 pathways leading to high concentrations of arachidonic acid and DHA (C22:6 n3). The results of this study confirm the close relationship between this pesticide metabolite and hepatic lipid dysfunction, underscoring its role as an emerging target for the prevention and therapy of nonalcoholic fatty liver disease (NAFLD).
