Research Study: Influence of a probiotic supplement on body composition and health in occupational shift-workers

Healthy shift-working (rotating, evening, or night shift) females needed to participate in a research study!

The UNC Department of Exercise and Sport Science is looking for healthy, overweight females (age 22 - 45 years; BMI ≥25 kg/m2) to participate in a research study on the UNC-Chapel Hill campus. The purpose of this research study is to determine the influence of probiotics on body composition, physical fatigue, mood, inflammation, and insulin sensitivity.   

Your total involvement will be about seven weeks, with three total visits to campus (one initial 30-minute visit, two subsequent visits each lasting 60-75 minutes). Visits will include:

  • A body composition assessment (regional fat distribution, fat mass, %body fat, lean mass, bone mineral density, total body water)
  • A low-intensity exercise test involving walking on the treadmill
  • Questionnaires
  • A blood draw for blood glucose, lipids, and inflammatory markers

You will then participate in a six-week intervention that consists of taking a daily probiotic or placebo supplement every evening.  Following the intervention, you will return for a final visit where all baseline-testing measures will be repeated. 

As a participant, you will be required to sign an informed consent document stating you understand all of the procedures and rights as a research subject. Additionally, you will receive information about your body composition, bone mineral density, insulin sensitivity, and inflammation levels. You will also be compensated $25 for your time.
