Aspartame in conjunction with carbohydrate reduces insulin levels during endurance exercise

BACKGROUND As most sport drinks contain some form of non-nutritive sweetener (e.g. aspartame), and with the variation in blood glucose regulation and insulin secretion reportedly associated with aspartame, a further understanding of the effects on insulin and blood glucose regulation during exercise is warranted. Therefore, the aim of this preliminary study was to profile the insulin and blood ...

Carbohydrate Dependence During Prolonged, Intense Endurance Exercise.

A major goal of training to improve the performance of prolonged, continuous, endurance events lasting up to 3 h is to promote a range of physiological and metabolic adaptations that permit an athlete to work at both higher absolute and relative power outputs/speeds and delay the onset of fatigue (i.e., a decline in exercise intensity). To meet these goals, competitive endurance athletes undert...

Carbohydrate ingestion during endurance exercise improves performance in adults.

This study was a systematic review with meta-analysis examining the efficacy of carbohydrate (CHO) ingestion compared with placebo (PLA) on endurance exercise performance in adults. Relevant databases were searched to January 2011. Included studies were PLA-controlled, randomized, crossover designs in which CHO ingestion not exceeding 8% and between 30 and 80 g/h during exercise of ≥1 h was eva...

The effects of Acute endurance exercise on Visfatin and insulin levels in obese women

Abtract Introduction: Visfatin is a newly discovered adipokine which is highly expressed in visceral adipose tissue that may induces changes in insulin resistance. The Aim of this study was to examine the Effect of Endurance Exercise on Visfatin and Insulin Levels In Obese Women. Method: present research is a semi-empirical study that 10 obese female volunteers (age 35.6±7.12 y, body mass in...

Metabolic Responses to Carbohydrate Ingestion during Exercise: Associations between Carbohydrate Dose and Endurance Performance

Carbohydrate (CHO) ingestion during exercise lasting less than three hours improves endurance exercise performance but there is still debate about the optimal dose. We utilised stable isotopes and blood metabolite profiles to further examine metabolic responses to CHO (glucose only) ingestion in the 20-64 g·h-1 range, and to determine the association with performance outcome. In a double-blind,...
