    Análisis del consumo de suplementos nutricionales en jugadores de la liga EBA
    (Murcia: Servicio de publicaciones de la Universidad de Murcia, 2017) Sánchez Oliver, Antonio Jesús; Grimaldi Puyana, M.
    La bibliografía sobre el consumo de suplementos nutricionales (SN) en jugadores de baloncesto es escasa. El objetivo del presente estudio fue evaluar el consumo de SN en un grupo de jugadores del Grupo C de la liga española de baloncesto amateur (EBA). Se registraron un total de 79 cuestionarios de 9 equipos diferentes. Éste fue diseñado y evaluado previamente mediante un pilotaje en el que se observó la validez del contenido, su aplicación, su estructura y su presentación. Los resultados muestran que el 100% de la muestra está a favor del consumo de SN dentro de la legalidad, el 71,2% afrma haberlos consumido en alguna ocasión y el 56,1% los consume en la actualidad. Los SN más consumidos por la muestra son bebidas deportivas (60,8%), proteínas de suero (18,9%), barritas energéticas (16,5%), complejo vitamínico (15,2%), proteína (no suero) (12,6%), creatina (10,1%) e hidratos de carbono (8,9%). Un alto porcentaje de los consumidores de SN piensa que han obtenido resultados positivos en el consumo de estos. Aunque con algunos matices, el porcentaje y los resultados sobre el consumo de SN en el presente estudio son similares a las aportaciones realizadas por otros estudios que evalúan la suplementación en deportistas.

    Docosahexaenoic acid supplementation during pregnancy as phospholipids or triglycerides produces different placental uptake but similar fetal brain accretion in neonatal piglets
    (CAMBRIDGE UNIVERSITY PRESS, 2017-11-23) Gázquez, Antonio; Ruíz-Palacios, María; Larqué Daza, Elvira; Fisiología
    The great variety of n-3 long chain polyunsaturated fatty acid sources raises the question of the most adequate for using as a docosahexaenoic acid (DHA) supplement during pregnancy. Placental and fetal availability of different DHA sources remains unclear. We investigated DHA availability in maternal lipoproteins, placenta and fetal tissues in pregnant sows fed DHA as phospholipid (PL) or triglyceride (TG) to identify the best DHA source during this period. Pregnant Iberian sows were fed with diets containing 0.8% DHA of total fatty acids as PL from egg yolk or TG from algae oil during the last third of gestation (40 days). Maternal tissues, placentas and fetal tissues were obtained at delivery and DHA quantified by gas-chromatography. MFSD2a carrier expression was analysed in both placenta and fetal brain by western blotting. Sows fed DHA-PL diet showed higher DHA incorporation in plasma LDL but not in plasma total lipids. No differences were found in DHA content between groups in maternal liver, adipose tissue or brain. Placental tissue incorporated more DHA in both total lipids and PL fraction in sows fed DHA-PL. However, this did not lead to an enhanced DHA accretion either in fetal plasma, fetal liver or fetal brain. MFSD2a expression was similar between both experimental groups. Maternal DHA supplementation during pregnancy in sow either as PL or TG produces similar DHA accretion in fetal tissues but not in placenta. Both fat sources are equally available for fetal brain.

    Nutritional review of the methodology applied in sports supplementation research
    (Mattioli1885, 2022-12-23) Cantero, Leticia; Conde-Pipo, Javier; Jimenez-Casquet, Maria José; Latorre, Jose Antonio; Gimenez-Blasi, Nuria; Martinez-Bebia, Manuel; Bach-Faig, Anna; Olea-Serrano, Fatima; Mariscal-Arcas, Miguel; Tecnología de Alimentos, Nutrición y Bromatología
    Both high-performance athletes and amateurs resort to taking supplements in order to improve their performance and/or their health. Many of them do not know the effects of these and take them without a professional supervision. The aim is to know the population who is studied by other different studies related to supplementation and improvement of sports performance and the nutritional method used in these cases. Systematic bibliographic research (March-May2021) was carried out in MEDLINE, with Boolean operators (((((caffeine[MeSH Major Topic]) OR (creatine[MeSH Major Topic])) OR (nitrate[MeSH Major Topic])) OR (sodium bicarbonate[MeSH Major Topic])) AND (dietary supplement[MeSH Terms])) AND (athletic performance[MeSH Terms]). 17 articles were included. Mean participants of these studies were 16.8subjects, which corresponds to a small sample. Only two studies were conducted to women. Several others were based on people who are not considered high-performance. In most of the selected studies, there is no a nutritional assessment, dietary record or follow-up of the subjects’ diet before and during the intervention, and this is a limitation. In order to reach accurate conclusions about supplementation and optimization of sports perfor mance, it is necessary to know the nutritional and hydration status, supplementation habits and lifestyle of the participants in these trials are.
