Summary

This study explores the impact of high-intensity exercise during fasting on energy metabolism and cognitive function in healthy adults. Changes in respiratory exchange ratio, blood substances, and cognitive performance will be measured after 24 and 34 hours of fasting with and without exercise in a randomized crossover design.

Conditions

  • Energy Metabolism

Interventions

BEHAVIORAL

34-hour fasting in sedentary conditions

Participants will fast for 34h after a standardized breakfast, refraining from physical activity.

BEHAVIORAL

34-hour fasting with high-intensity exercise

Participants will fast for 34h after a standardized breakfast, performing a high-intensity exercise session 6-10 hours aprox. after starting the fasting period.
