Lara Carlson publishes in 'Journal of the International Society of Sports Nutrition'

Lara Carlson, Ph.D., FACSM, CSCS, assistant professor in the Department of Exercise and Sport Performance, recently published her research in the Journal of the International Society of Sports Nutrition.

The publication, titled “Influence of carbohydrate ingestion on salivary immunoglobulin A following resistance exercise,” examined the impact of carbohydrate (CHO) supplementation on salivary immunoglobulin A (s-IgA) levels, interleukin 2 (IL-2), and interleukin 5 (IL-5) following acute resistance exercise (RE).

Heavy exercise stresses immune function and can temporarily impact components of both innate and adaptive immunity; however, CHO supplementation has been shown to attenuate the decline in some measures of immune function after exercise. One of the first lines of defense in the innate immune system against pathogens is s-IgA. The current study found that IL-5 decreases after RE, but s-IgA and IL-2 levels remain stable. CHO ingestion prior to, during or following RE did not appear to alter salivary immune responses.
