UNLABELLED
Recently, it has been shown that ingestion of solutions with glucose (GLU) and fructose (FRC) leads to 20%–50% higher CHO oxidation rates compared with GLU alone. Although most laboratory studies used solutions to deliver CHO, in practice, athletes often ingest CHO in the form of gels (semisolid). It is currently not known if CHO ingested in the form of a gel is oxidized as effectively as a drink.
PURPOSE
To investigate exogenous CHO oxidation from CHO provided in semisolid (GEL…

Carbohydrate Intake in Form of Gel Is Associated With Increased Gastrointestinal Distress but Not With Performance Differences Compared With Liquid Carbohydrate Ingestion During Simulated Long-Distance Triathlon.

This study suggests that administration of GEL does not alter long-distance triathlon performance when compared with LIQ, but GEL seems to be associated with reduced GI tolerance, and athletes should consider this a potential disadvantage of Gels administration during long- distance triathlon.

It is confirmed that CES supplementation improves the moderate intensity endurance capacity of active females during the follicular phases of the menstrual cycle, however, the exogenous oxidation of carbohydrate does not seem to explain the improved capacity after CES supplementation.

Ingestion of energy gels during prolonged cycling elevates blood glucose levels and enhances subsequent performance, whereas a more frequent ingestion elicits additional performance benefits.

It appears that CH intake correlates positively with mood, but in all other variables, there are no differences depending on the product.
A Step Towards Personalized Sports Nutrition: Carbohydrate Intake During Exercise
- MedicineSports Medicine

These new guidelines may replace the generic existing guidelines for carbohydrate intake during endurance exercise and take into account the duration (and intensity) of exercise and advice is not restricted to the amount of carbohydrate; it also gives direction with respect to the type of carbohydrate.

Findings resulted in new recommendations that are dependent on the duration and intensity of exercise and not only specify the quantity of carbohydrate to be ingested but also the type.

Despite high CHO gel intake, and regardless of the blend (GLU vs. GLU+FRC), average scores for GI symptoms were at the low end of the scale, indicating predominantly good tolerance during a 16-km run, Nevertheless, some runners experienced serious problems, and individualized feeding strategies might be required.

It is demonstrated that, when fructose and glucose are ingested simultaneously at high rates during cycling exercise, exogenous carbohydrate oxidation rates can reach peak values of approximately 1.3 g/min.

The present study demonstrates that with ingestion of large amounts of maltodextrin and fructose during cycling exercise, exogenous carbohydrate oxidation can reach peak values of approximately 1.5 g.min, and this is markedly higher than oxidation rates from ingesting maltodesxtrin alone.

Ingestion ofGF led to an 8% improvement in cycling time-trial performance compared with ingestion of G, suggesting that GF led to a sparing of endogenous CHO stores, because GF has been shown to have a greater exogenous CHO oxidation than G.

The results of this study show that the carbohydrate present in C-drink, although it has the propensity to form a gel, empties from the stomach faster than that of an isoenergetic carbohydrate solution (G-drinks) without potentiating increased circulating blood glucose or insulin levels.
