Nutritional Supplementation and Muscle Health: A Pilot Study on Immune Function

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 12 (actual)
• Sponsor: Central Arkansas Veterans Healthcare System · Federal
• Sex: All
• Age: 60 Years – 80 Years
• Healthy volunteers: Accepted

Summary

The ability of older adults to improve their muscle strength through exercise training appears related to how well their immune system functions. Thus, a nutritional supplement which improves immune function could theoretically boost strength gained for older adults from exercise. The purpose of this pilot study is to determine if a nutritional supplement has any effect on immune function. Veterans (age 60-80 yrs, N=12) be randomized in a double-blind placebo-controlled fashion to consume supplement or placebo for four weeks. After two weeks of consumption, subjects will be treated with a vaccine for tetanus, diphtheria, and pertussis. Blood will be drawn from each subject before and after vaccination to determine the effects of the supplement on immune response to vaccination. Additionally, subjects will undergo blood draw and muscle biopsy before and after two weeks of supplementation to determine the effects of supplementation on other measures of immune function (e.g. cytokine and growth factor levels). This is an important issue due to the serious health consequences associated with muscle loss in older adults and the need for improved strategies for rehabilitation.
