“…Supporting the aforementioned, Rabassa-Blanco et al published a review on the effect of protein and BCAA supplements on changes in body composition, muscle mass, central or peripheral fatigue, muscle strength, muscle damage, and anabolic response in muscle recovery. They showed that protein supplements, in association with a balanced diet and training, can improve performance and muscle mass [ 19 ]. Despite the number of studies on BCAAs, there seems to be no consensus on the recommended amount per dose in relation to training.…”

“…Despite the number of studies on BCAAs, there seems to be no consensus on the recommended amount per dose in relation to training. Of all the BCAAs, specifically, leucine has shown positive effects on muscle mass, in reducing central fatigue and consequently improving performance [ 19 , 70 , 71 ].…”

“…The BCAAs are Leucine, Isoleucine, and Valine, and benefits related to energy metabolism in the muscle are attributed to them [ 17 ]. Specifically, leucine has been shown to promote muscle protein synthesis, decrease central fatigue and improve performance [ 18 , 19 , 20 , 21 , 22 ].…”

Recent years have seen a rise in the popularity of the consumption of sports-related supplements. However, the hypothesis is raised that it is necessary to analyze the quality aspects of these supplements in relation to the information provided on the label, to avoid associated risks and obtain the greatest possible benefit from their consumption. Therefore, the aim of this study has been to carry out an analysis or screening of the protein supplements that are currently marketed in Spain. We analyzed the labels of 52 protein sports supplements available both in physical stores and online. The analysis consisted of addressing three relevant aspects considering the labeling: (a) the legislative framework in which the supplements are marketed, (b) the quality of the protein, and (c) the presence of other ingredients according to the specifications of the label. In the legislative context, there do not seem to be any specific regulations to guarantee consumer protection, which can lead to unfair practices and misleading advertising. Most of the supplements analyzed to comply with the requirements of their current regulations. However, claims about their benefits that are not allowed under European legislation have been found in some of them. Regarding composition and according to label information, the supplements have been found to provide a sufficient dose of protein in terms of recommended protein intake per serving. Regarding the presence of other ingredients and according to the information on the label, most of them, except for egg supplements, contain other ingredients. Colostrum was also found in one of the supplements evaluated. The conclusions of the study reveal that, due to a lack of knowledge or misleading advertising practices, supplements are often not used properly. The information provided is essential for both professionals and consumers to avoid the risks associated with consumption, such as unintentional doping, interactions between ingredients that reduce the quality of the supplement, and consumption of supplements inappropriately, among others.

“…Insulin is an anticatabolic, which achieves muscle protein anabolism by the inhibition of muscle protein breakdown [22], so CHO intake after exercise could be beneficial to potentiate exercise-induced adaptations. However, evidence is mixed in this regard, and it seems that supplying an optimal amount of high-quality proteins, specifically proteins that contain an adequate dose of leucine (e.g., 3–4 g/dose) [23] after exercise can be enough to achieve a positive protein balance and stimulate an anabolic response [24]…”

Strong evidence during the last few decades has highlighted the importance of nutrition for sport performance, the role of carbohydrates (CHO) being of special interest. Glycogen is currently not only considered an energy substrate but also a regulator of the signaling pathways that regulate exercise-induced adaptations. Thus, low or high CHO availabilities can result in both beneficial or negative results depending on the purpose. On the one hand, the depletion of glycogen levels is a limiting factor of performance during sessions in which high exercise intensities are required; therefore ensuring a high CHO availability before and during exercise is of major importance. A high CHO availability has also been positively related to the exercise-induced adaptations to resistance training. By contrast, a low CHO availability seems to promote endurance-exercise-induced adaptations such as mitochondrial biogenesis and enhanced lipolysis. In the present narrative review, we aim to provide a holistic overview of how CHO availability impacts physical performance as well as to provide practical recommendations on how training and nutrition might be combined to maximize performance. Attending to the existing evidence, no universal recommendations regarding CHO intake can be given to athletes as nutrition should be periodized according to training loads and objectives.

“…Las proteínas son un componente vital para el organismo siendo esenciales para el crecimiento y el mantenimiento de las estructuras corporales. También pueden ser utilizadas como fuente de energía en ausencia de los carbohidratos y grasas, sin embargo, no es una función que deban cumplir (Rabassa & Palma, 2017).…”

Introducción. La industrialización alimentaria ha generado a nivel mundial una transición alimentaria que favorece la malnutrición, consistiendo en carencias y excesos por desequilibrio en la ingesta calórica. El objetivo del estudio fue analizar el contenido nutricional de las comidas rápidas y resaltar sus repercusiones en la salud. Métodos. Se analizó el contenido nutricional de las comidas rápidas disponibles en las Tablas de Composición de Alimentos de Centroamérica (TCA) del Instituto de Nutrición de Centroamérica y Panamá (INCAP). Los valores de composición nutricional (grasa total, carbohidratos, proteína, fibra) y de energía, en 100 g (o 100 ml) de porción comestible de seis subcategorías fueron considerados. Se realizó un análisis estadístico descriptivo univariado para obtener las medidas de tendencia central y dispersión de cada variable de las subcategorías. Se aplicó un análisis de varianza (ANDEVA), con una separación de medias Duncan. Resultados. Se identificó un alto contenido proteico en las seis subcategorías, el más alto fue en la de “pollo frito y nuggets” (16 g) y el más bajo en “burritos” (9 g). En general, se presentaron niveles bajos de fibra, con un promedio de 2.2 g. Conclusión. La comida rápida estudiada se caracteriza por tener un alto contenido energético, de carbohidratos, proteína y grasa y bajo contenido de fibra. Su consumo habitual es una de las principales causas de aumento de peso corporal y presentan un riesgo sustancial a desarrollar enfermedades no transmisibles a largo plazo, por lo que disminuir su consumo es fundamental para cuidar la salud.
