Individuals Age 18-65 and Not Currently Involved in a Structured Exercise Program Asked to Participate
Released: Monday, February 17, 2014

BATON ROUGE, LA – Pennington Biomedical Research Center announced today that it is conducting a new clinical trial to compare the effects of physical activity and lifestyle changes on energy balance and how these changes may impact an individual’s body composition.  This study, called E-MECHANIC:  Examination of Mechanisms of Exercise-Induced Weight Compensation, is open to adults age 18-65 who are not currently involved in a structured exercise program.

The co-principal investigators of E-MECHANIC, which is funded by the National Institutes of Health (NIH), are Timothy S. Church, M.D., M.P.H., Ph.D., professor and director of the Preventive Medicine Laboratory, and Corby Martin, Ph.D., associate professor and director of Behavioral Science and Epidemilogy, both of Pennington Biomedical.  E-MECHANIC will examine how three different exercise programs can affect changes in your body and influence your overall health.  Participants will complete a 6-month exercise intervention at the Pennington Biomedical Fitness Center.  Those enrolled in one of the exercise groups will visit the Fitness Center 3-5 times per week for sessions that will last approximately 60 minutes.  Those enrolled in the healthy living group will receive weekly health tips through text message, email, or postal mail.  This intervention will also include monthly seminars at Pennington Biomedical on health-related topics.  All procedures associated with the study will be provided at no cost to participants.    

“This innovative study will help us learn how exercise affects our metabolism, body composition, and health.  Results from the study will help us develop more effective exercise interventions that maximize health improvements,” says Martin.

The study will require participants to complete an orientation visit to determine eligibility.  Participants are also required to complete 5 screening visits and 11 clinic visits, and enrolled participants will receive up to $400 for participation.
