VIVA Study

Women's Health

Study Purpose

Recent research has shown that new fat cells are constantly formed and replaced in the human body. The VIVA research study will assess fat tissue in both physically active (exercising) and inactive (sedentary) women to learn more about how exercise may affect fat cells in the body.

Potential participants will be classified as either sedentary or very physically active to determine eligibility.


Qualified participants will drink ‘heavy water’ for 6 weeks. Heavy water is ordinary water that is enriched with a non-radioactive isotope that allows researchers to measure fat cell function in the body.
