Overview

Brief 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.

•Diagnosed with a chronic endocrine, digestive, rheumatic, neurological, cardiac, pulmonary, autoimmune, or infectious condition that affects energy metabolism.
•Presenting any signs or symptoms of illness that, in the research team's opinion or based on the American College of Sports Medicine guidelines, could contraindicate the implementation of 34-hour fasting periods and/or high-intensity exercise.
•Pregnant or breastfeeding.
•Using medications or supplements that may alter energy metabolism.
•Currently undergoing or having undergone any type of nutritional intervention or treatment in the past 3 months.
•Engaging in more than 5 hours per week of habitual moderate-to-vigorous cycling.
•Any other condition that, in the research team's opinion, discourages participation in the study.
