Reoxcyn Innovation Group funds Appalachian research into possible health benefits of flavonoid supplements after strenuous activity

BOONE, N.C. — A study conducted by Appalachian State University’s Human Performance Lab, which is located at the North Carolina Research Campus (NCRC) in Kannapolis, will test two weeks’ worth of mixed flavonoid versus placebo supplementation on the immune system, oxidative stress and inflammation of individuals following strenuous exercise. The study is funded by a $97,270 grant from Reoxcyn Innovation Group LLC.

Dr. David Nieman, professor in Appalachian’s Department of Health and Exercise Science and director of the Human Performance Lab, is the project’s lead researcher. Other collaborators on the project include Dr. Jennifer McBride, assistant director and research scientist in the Human Performance Lab, and Dr. Giuseppe Valacchi, associate professor in the Department of Animal Science at North Carolina State University.

“Prolonged and intensive exercise increases oxidative stress, inflammation, muscle damage, stress hormone levels, and immune dysfunction, which collectively represents exercise-induced physiological stress,” Nieman said.

According to Nieman, plant flavonoids — a type of plant chemical found in fruits, green tea, vegetables and other plant foods — may provide benefits for athletes and others who engage in strenuous activity, including improving immune function and lessening the oxidative stress and inflammation that occurs following bouts of vigorous exercise.

The purpose of the study, Nieman said, is to investigate the influence of two weeks’ worth of mixed flavonoid versus placebo supplementation on the body’s immune system, as well as the oxidative stress and inflammation biomarkers in 20 male and female participants after a cycling exercise (75 kilometers) is performed by each individual.

Blood samples will be collected from the study participants pre-supplementation and then pre- and post-exercise (1.5 hours after the exercise is performed, and then 21 hours following the exercise test), Nieman explained, with immune cells separated and analyzed for oxidative stress and inflammation biomarkers.

Nieman said he and his team hypothesize that two weeks of mixed flavonoid versus placebo supplementation will support immune function and lessen post-exercise increases in oxidative stress and inflammation in the test subjects.

Emily Zerona, a junior public health major at Appalachian from Concord, is assisting with the research project.
