Summary

It is well established that a bout of 50 min of continuous moderate intensity exercise, improves insulin sensitivity up to 48 hours after the bout. However, it is less well known, what is the exercise type more efficient to buffer the elevations in blood glucose elicited by carbohydrate ingestion. The purpose of this study is to elucidate if intervalic exercise is superior to continous on improving postprandial glycemic control.

Detailed description

Carbohydrate oxidation, glucose and insulin blood concentrations, isotopically measured rate of appearance of endogenous and exogenous glucose will be measured in 4 ocassions. Participants will undergo in a cross-over randomized fashion the following trials: 1. Exercise pedalling during 50 min at 60% of their VO2max followed by an oral glucose tolerance test (OGTT). 2. Exercise pedalling during 50 min in a hot environment (33ºC) at 60% of their VO2max followed by an oral glucose tolerance test (OGTT). 3. Exercise pedalling during 50 min using intervalic bouts averaging 60% of VO2max followed by an oral glucose tolerance test (OGTT). 4. No exercise, followed by an oral glucose tolerance test (OGTT).
