Pennington Biomedical Seeks Volunteers to Test Arginine’s Effect on Fatigue, Physical Performance, Immune Function

LSU Pennington Biomedical Research Center is looking for a “few good men” to help evaluate the amino acid arginine and its effects on the process that bodies go through to convert food into energy.

Pennington is putting together a team of study participants whose efforts could help warfighters stave off fatigue, improve their performance, and better handle stress.

The study is limited to men between the ages of 18 and 39 who are physically active and whose body mass index is between 18.5 and 25, or the normal weight range.

Arginine is an essential amino acid found in various foods like turkey, pork, and chicken. Arginine is thought to help improve blood flow and immune function.

“The Supplementation Trial on Arginine with Metabolic Profiling (STAMP) will examine the effects of arginine on hormones in the blood to determine if arginine can benefit warfighter performance,” said Dr. John Apolzan, assistant professor of research at Pennington Biomedical and the primary investigator on the study.

Participation in the study will last approximately five to six weeks. The study includes four center visits. Participants will eat study food for breakfast at Pennington Biomedical before clinic visits on four days. Lunch and dinner meals will be packed to go. All study-related meals will be provided at no cost to participants.

Total compensation for completion of the study is $240.
