We're recruiting adults for a research study to examine the effects of nightshift work on cardiovascular and muscle health!
Who may participate?
Participants must be 18–50 years old, apparently healthy, and currently working nightshifts, defined as working at least 3 hours between 11:00 PM and 6:00 AM on at least 2 days per week. Participants must have no history of cardiac or metabolic disease, no smoking or beta-blocker use, and weigh more than 110 pounds.
Study activities include:
- Health, physical activity, exercise history, and sleep questionnaires
- Cardiovascular and metabolic function testing
- Maximal cycle exercise testing
- Handgrip strength testing
- Body composition assessment
- Blood draws
Participation includes one study visit lasting approximately 2.5 hours in YOLO Hall at Chico State. Participation is voluntary, and the study involves low potential risk of fatigue, discomfort, and bruising.
