“…In support of this, when fructose was co-ingested during the first 4 h of post-exercise recovery, endurance exercise capacity during a subsequent exercise bout (i.e. treadmill running to exhaustion at 70%V O 2 max ) was shown to be increased by ß32.4% compared to ingesting glucose (polymers) only (Maunder et al 2018). This clearly shows the potential benefit of combining glucose with fructose in the first hours of post-exercise recovery when optimal performance during a subsequent endurance exercise session is key.…”

Carbohydrate availability is important to maximize endurance performance during prolonged bouts of moderate‐ to high‐intensity exercise as well as for acute post‐exercise recovery. The primary form of carbohydrates that are typically ingested during and after exercise are glucose (polymers). However, intestinal glucose absorption can be limited by the capacity of the intestinal glucose transport system (SGLT1). Intestinal fructose uptake is not regulated by the same transport system, as it largely depends on GLUT5 as opposed to SGLT1 transporters. Combining the intake of glucose plus fructose can further increase total exogenous carbohydrate availability and, as such, allow higher exogenous carbohydrate oxidation rates. Ingesting a mixture of both glucose and fructose can improve endurance exercise performance compared to equivalent amounts of glucose (polymers) only. Fructose co‐ingestion can also accelerate post‐exercise (liver) glycogen repletion rates, which may be relevant when rapid (<24 h) recovery is required. Furthermore, fructose co‐ingestion can lower gastrointestinal distress when relatively large amounts of carbohydrate (>1.2 g/kg/h) are ingested during post‐exercise recovery. In conclusion, combined ingestion of fructose with glucose may be preferred over the ingestion of glucose (polymers) only to help trained athletes maximize endurance performance during prolonged moderate‐ to high‐intensity exercise sessions and accelerate post‐exercise (liver) glycogen repletion.

“…En relación a esto, se recomienda ingerir una mezcla de glucosa + fructosa que proporcione una dosis óptima de CHO para la restauración efectiva del glucógeno hepático y muscular, lo que reduce el malestar gastrointestinal ocasionado por la elevada ingesta de CHO (Alghannam et al, 2018). Esto queda latente al ver que el uso de sacarosa (disacárido constituido por una cantidad equimolar de glucosa y fructosa) parece ser más efectivo que el consumo solo de glucosa, a lo que se le suma, como se ha comentado anteriormente, la no aparición de molestias gastrointestinales frente a la ingesta de esta última sola (Fuchs et al, 2016;Maunder, Podlogar, & Wallis, 2017). Además, un reciente estudio ha mostrado que cuando la recuperación debe ser inmediata, la mezcla de glucosa y fructosa (o sacarosa) a una tasa de ≥1,2 g/kg/hora puede mejorar las tasas de repleción de glucógeno al tiempo que minimiza la dificultad gastrointestinal (Gonzalez, Fuchs, Betts, & van Loon, 2017).…”

Las estrategias nutricionales durante la fase de recuperación del deportista son fundamentales. Uno de los principales objetivos de la recuperación es la reposición del glucógeno muscular. Este aspecto se hace más importante cuando los deportistas se enfrentan a entrenamientos intensos o eventos competitivos con cortos periodos de recuperación. Además, la manipulación deliberada de su disponibilidad puede mejorar las adaptaciones moleculares al entrenamiento. La presente revisión tiene por objetivo informar sobre los aspectos fisiológicos básicos de esta situación, así como conocer el momento del consumo, la cantidad, el tipo y la interacción de diferentes nutrientes con los hidratos de carbono, para poder maximizar o jugar con la reposición del mismo en función de las necesidades y/o las estrategias planteadas. El glucógeno ya no debe ser visto como un simple almacén de energía sino como una molécula que puede desencadenar numerosos procesos celulares importantes para el deportista. Nutritional interventions play a fundamental role during the post-exercise recovery phase. One of the main goals of recovery is restoring muscle glycogen stores. This becomes more important when athletes are subjected to intense training or competition with short recovery periods be-tween bouts. Furthermore, manipulating muscle glycogen availability can improve molecular adaptations to training. The objective of this review is thus to present the basic physiological aspects of this phenomenon, and to discuss carbohydrate consumption, timing, type, and amount, as well as its interaction with different nutrients, in order to maximize or play with the restoration of muscle glycogen depending on the needs and/or the strategies proposed. Glyco-gen should no longer be seen as a simple form of energy storage, but as a molecule that can trigger numerous cellular processes important for athletic performance.

“…Furthermore, ingestion of fructose‐containing carbohydrates during recovery from exercise can enhance subsequent endurance running capacity, compared to glucose‐based carbohydrates (Maunder et al . ). Therefore, at least for specific scenarios, fructose‐containing carbohydrate can be useful for athletic performance.…”

“…Indeed, when the total amount of carbohydrate is matched, the ingestion of fructose-glucose mixtures can double the rate of liver glycogen repletion in recovery from exercise, when compared to glucose-based carbohydrates (Fuchs et al 2019). Furthermore, ingestion of fructose-containing carbohydrates during recovery from exercise can enhance subsequent endurance running capacity, compared to glucose-based carbohydrates (Maunder et al 2018). Therefore, at least for specific scenarios, fructose-containing carbohydrate can be useful for athletic performance.…”
