Efectos de bebidas carbohidratadas y proteicas sobre la recuperación del esfuerzo / Effects of carbohydrate-protein beverages on recovery from exercise

Este artículo aporta una revisión del efecto de la coingesta de la proteína de suero de leche y proteína caseína administradas en bebidas carbohidratadas, sobre la recuperación y los parámetros del daño muscular en ejercicios de larga duración. La búsqueda se ha realizado en abril de 2013 en las bases de datos del ISI Web of Knowledge, SCOPUS, Sport Discuss, PubMed, Medline, Sportdiscus, y en las bases de datos CINDOC en las redes CTI-CSIC, RESH, DICE y DIALNET cruzando los descriptores "Exercise", "Resistance training" y "Recovery" con los términos "Ergogenic beverage", "Casein Protein" y "Whey Protein". La estrategia nutricional más respaldada es la ingesta de un preparado líquido carbohidratado en donde se combinan proteínas de diferentes fuentes sobre pruebas de esfuerzos prolongados similares a la competición tanto en deportes individuales como en colectivos, con resultados discrepantes (AU)

This manuscript shows a review about the effects of the whey and casein protein on recovery and parameters of muscle damage in long-term exercise. The search was conducted in April 2013 in the databases of ISI Web of Knowledge, SCOPUS, PubMed, Medline, SportDiscus, and databases on Spanish networks CINDOC CTI-CSIC, RESH, DICE, and DIALNET crossing the descriptors "Exercise", "Resistance training" and "Recovery" with the terms "Ergogenic Beverage", "Casein Protein" and "Whey Protein". The most used nutritional strategies are based in a carbohydrate beverage which combines different protein sources on prolonged exercise tests similar to sports competition, in both individual and collective sports, with discrepant results (AU)

Modified proteins in allergy prevention.

Around 2.5% of neonates experience hypersensitivity reactions to cow's milk protein during the first year of life, which is highly associated with early exposure to cow's milk. To prevent early allergy development, cow's milk proteins in infant formulas were modified by hydrolyzation processes for use in children at high atopic risk who need milk supplementation in the first months of life. Dependent on the degree of modification, hydrolyzed cow's milk formulas are differentiated into extensively and partially hydrolyzed whey or casein hydrolysates (pHF, eHF). However, their allergy-preventive potential seems not only to dependent on the degree but also on the process of hydrolysis. pHF and eHF can be used for primary prevention of allergy in infants at high atopic risk, while only eHFs are indicated for secondary prevention in patients with manifest cow's milk allergy. In clinical trials a consistent trend to a reduction in atopy, mainly atopic eczema and food allergy, by certain pHFs and eHFs could be demonstrated in children with a familial risk of atopy until the age of 6 years. Because more than 50% of allergic children do not have a family history of atopy, it would be worthwhile to consider primary allergy prevention with hydrolysates for all children who need supplementation to breastfeeding.

Hydrolysed protein formulas: thoughts from the Isle of Wight meeting.

The meeting held on the Isle of Wight on 3 March 1995 was organised to discuss some of the recent evidence concerning the use of hydrolysed milk formulas not only in the treatment of cow's milk allergy but also in programmes designed to reduce or prevent other atopic disease. These products and their prophylactic use in particular have generated an amount of controversy firstly when they were introduced as a starting formula in the United States and secondly in Europe where paediatric, allergy and nutrition groups have issued various statements on their use (ESPGAN, 1993; Bjorksten, 1994; ESPACI, 1993; Bindels & Boerma, 1994). The Isle of Wight meeting did not attempt to produce a concensus statement. Nor is this paper an attempt to summarise or bring together the views expressed. Rather it reflects the views of the authors tempered by experience and the evidence presented at the meeting. Seven questions are explored.
