Volunteers needed for study of sleep and metabolism

Researchers at James Madison University are conducting a study to understand how a single night of sleep restriction may influence the body’s response to a single meal.

We are seeking individuals who meet the following criteria:

• 18-35 years old OR 60 years of age or older
• Participate in either less than 60 OR more than 150 minutes of physical activity per week
• Do not have any major metabolic disease
• Are interested in learning more about their metabolic health and physical activity habits

What does the study involve?

• Visit 1 (~30 minutes)
  • Complete questionnaires about health history, physical activity, and sleep habits and receive an accelerometer to track physical activity habits
• Visits 2 and 3 (~4.5 hours)
  • Consume a chocolate pie followed
  • Undergo simple finger stick blood tests and provide saliva samples
• Additional requirements
  • One night of sleep restriction (<4 hours of sleep) before visit 2 or 3

This study has been approved by the IRB, protocol #IRB-FY25-742.
