PURPOSE This study examined the effect of consuming carbohydrate- (CHO) electrolyte solution on running performance after different-glycemic-index (GI) meals. METHODS Nine men completed 3 trials in a randomized counterbalanced order, with trials separated by at least 7 days. Two hours before the run after an overnight fast, each participant consumed a high-GI (GI = 83) or low-GI (GI = 36) CHO meal or low-energy sugar-free Jell-O (GI = 0, control). The 2 isocaloric GI meals provided 1.5 g…

Impact of pre-exercise feedings with a low or high glycemic index on the ergogenic effects of carbohydrate mouth-rinsing during cycling

Whether the glycemic index of a pre-exercise meal affected time-trial (TT) performance in cyclists using a CHO mouth-rinse during exercise was examined and no systematic differences between L-CHO and H-CHO were found.

Effect of Galactose Ingestion Before and During Exercise on Substrate Oxidation, Postexercise Satiety, and Subsequent Energy Intake in Females

It is demonstrated that ingesting a solution containing GAL before and during exercise can positively impact postexercise satiety and energy balance throughout the day, compared to a more readily available and widely consumed form of CHO.

Effect of Glycemic Index of a Pre-exercise Meal on Endurance Exercise Performance: A Systematic Review and Meta-analysis

There was no clear benefit of consuming a LGI pre-exercise meal for endurance performance regardless of carbohydrate ingestion during exercise, and no consistent metabolic responses during exercise were observed with either meal type.

Glycemic index and endurance performance.

The results indicate that GI is not as important as consuming CHO itself, and athletes are encouraged to follow standard recommendations for CHO consumption and let practical issues and individual experience dictate the use of HGI or LGI meals and supplements before, during, and after exercise.

Influence of the Glycemic Index of Pre-exercise Meals in Sports Performance: A Systematic Review

There is no evidence that the pre-exercise meal GI influences performance, and the results as well as the methodologies used were heterogeneous; therefore, there are no clear advantages in determining the specific GI of thePre-ex exercise meal.

Glycemic index of pre-exercise meal and glucose metabolism in aerobic physical activity

Based on the recurrence of some results, low glycemic index foods cause fewer postprandial glycemic alterations which may entail a more stable behavior throughout the exercise, making it a more conservative nutritional strategy for the general population.

Effects of Acute Carbohydrate Supplementation on Endurance Performance

Car carbohydrate supplements with an appropriate composition and administration regimen can have large benefits on endurance performance and the moderating effects of gender and salt were unclear.

The effects of a coconut beverage on blood glucose and lactate concentrations

Examination of the effects of a coconut beverage on blood glucose and lactate levels found that Supplementing with CB can provide the same benefits as G in maintain blood glucose.

The effect of moderate glycemic energy bar consumption on blood glucose and mood in dancers.

It is concluded that skipping breakfast can have an unfavorable effect on the pleasure-displeasure state of dancers, as well as the physiological and metabolic benefits of CHO as an exogenous energy source in dancers.



Carbohydrate intake during prolonged cycling minimizes effect of glycemic index of preexercise meal.

When CHO is ingested during exercise in amounts presently recommended by sports nutrition guidelines, preexercise CHO intake has little effect on metabolism or on subsequent performance during prolonged cycling (approximately 2.5 h).

Effect of the glycaemic index of pre-exercise carbohydrate meals on running performance

The results indicate that compared with an isocaloric high GI meal, the consumption of a low GI meal 2 h before a 21-km performance run is a more effective means of improving performance time.

Influence of high and low glycemic index meals on endurance running capacity.

It is demonstrated that although there is a relative shift in substrate utilization from CHO to fat when a low GI meal is ingested before exercise compared with that for a high GI meal, there is no difference in endurance running capacity.

Ingestion of a high-glycemic index meal increases muscle glycogen storage at rest but augments its utilization during subsequent exercise.

Although the LGI meal contributed less CHO to muscle glycogen synthesis in the 3-h postprandial period compared with the HGI meal, a sparing of Muscle glycogen utilization during subsequent exercise was observed in theLGI trial, most likely as a result of better maintained fat oxidation.

A low glycemic index meal before exercise improves endurance running capacity in men.

Investigation of the effects of ingesting a low (LGI) or high (HGI) glycemic index carbohydrate (CHO) meal 3 h prior to exercise on endurance running capacity found it resulted in a greater endurance capacity than after the ingestion of a HGI meal.

Effect of frequency of carbohydrate feedings on recovery and subsequent endurance run.

It is suggested that serial consumption of a high GI meal during a 4-h recovery increased the reliance on CHO oxidation for energy provision during a subsequent run when compared with a single feeding.

Effect of CHO loading patterns on running performance.

It appears that the amount, rather than the nature, of the CHO consumed during the 3-day isoenergetic CHO loading may be the most overriding factor on subsequent metabolism and endurance run performance.

Influence of carbohydrate dosage on exercise performance and glycogen metabolism.

Examination of the effects of ingestion of carbohydrate (CHO) solutions of 0 (WP), 6 ( CHO-6), 12 (CHO-12), and 18 g CHO/100 ml on performance and muscle glycogen use found no differences in glycogenUse or depletion patterns between the WP and the two CHO-12 trials.

Effects of carbohydrate ingestion on gastric emptying and exercise performance.

The performance data showed that in all of the CHO trials, significantly more work was produced compared to the WP trial, and only the volume in the CHO-5 trial was significantly different from WP.

Carbohydrate feeding before exercise: effect of glycemic index.

It is suggested that a low GI pre-game meal may prolong endurance during strenuous exercise by inducing less post-prandial hyperglycemia and hyperinsulinemia, lower levels of plasma lactate before and during exercise, and by maintaining plasma glucose and FFA at higher levels during critical periods of exercise.
