ClinConnect Summary

This clinical trial is studying how different levels of physical activity affect the body’s energy use in adults. The main question is whether exercising more can keep increasing the total amount of energy the body uses in a day. To find out, participants will wear a device that tracks their daily physical activity, have their total energy use measured through a special water test, and spend time in a controlled room where their resting energy use and how their body uses energy after eating will be checked.

Adults of all genders with a body mass index (BMI) of 18.5 or higher may be eligible to join, as long as they don’t have certain health conditions like recent major surgery, serious heart or metabolic diseases (like diabetes or high blood pressure), exercise injuries, infections, mental health disorders, or recent attempts to lose or gain weight. Pregnant or breastfeeding individuals and those with metal implants or autism are also excluded. If you join, you can expect to be closely monitored through these tests to better understand how your body uses energy with different amounts of physical activity. This study has not started recruiting yet, but it aims to help us learn how exercise affects energy use, which could be important for health and fitness recommendations.
