Study Summary

This trial will study the effects of consuming a mixture of glucose and fructose versus glucose alone on the body's use of carbohydrates during exercise and physical performance. Participants will go through various tests and measurements to

Who is the study for?

This trial is for individuals who are willing to participate in a study examining how different carbohydrate combinations affect exercise performance and energy use. Participants should be comfortable with exercise protocols, including cycling, and must undergo various tests such as body composition assessments, blood draws, and muscle biopsies.Check my eligibility

What is being tested?

The study is testing the effects of consuming glucose alone or combined with fructose on carbohydrate burning rates during aerobic exercise under balanced and deficit energy conditions. It involves controlled diet, steady-state cycling exercises followed by a time trial test to measure physical performance.See study design

What are the potential side effects?

Since this trial involves dietary interventions rather than drugs or medical procedures, side effects may include gastrointestinal discomfort from the carbohydrate drinks or temporary soreness from muscle biopsies.

Experimental Treatment

Active Control

Group I: Energy Deficit: Glucose plus FructoseExperimental Treatment1 Intervention

Following 48 hours of consuming an energy deficit diet, volunteers complete 80 min of steady-state (60 ± 5% V̇O2peak) exercise on a cycle ergometer while consuming 53 g of glucose and 27 g of fructose.

Group II: Energy Balance: Glucose plus FructoseExperimental Treatment1 Intervention

Following 48 hours of consuming an energy balance diet, volunteers complete 80 min of steady-state (60 ± 5% V̇O2peak) exercise on a cycle ergometer while consuming 53 g of glucose and 27 g of fructose.

Group III: Energy Balance: GlucoseActive Control1 Intervention

Following 48 hours of consuming an energy balance diet, volunteers complete 80 min of steady-state (60 ± 5% V̇O2peak) exercise on a cycle ergometer while consuming 80 g of glucose

Group IV: Energy Deficit: GlucoseActive Control1 Intervention

Following 48 hours of consuming an energy deficit diet, volunteers complete 80 min of steady-state (60 ± 5% V̇O2peak) exercise on a cycle ergometer while consuming 80 g of glucose
