Student research on the impact of carbonated beverage consumption after athletic performance to be presented at annual forum

Bonnie McKee, a senior pursuing a bachelor of science degree in biology from Abeline, Kan., will join fellow students for the research poster, "Do Carbonated Beverages Affect Plasma Lactate Levels and Athletic Performance?" at The Washburn Apeiron: A Forum of Student Research, Scholarship and Creativity on Friday, April 18.

The group noted in the abstract, "This study was conducted to determine if similar results were found when subjects were asked to perform endurance type exercises to volitional fatigue after consuming carbonated beverages. Each subject was given the opportunity to ride a bike with increasing resistance levels over time. (50 watts for the baseline resistance, increased by 30 watts every 5 minutes.) Subjects were asked to continue pedaling at a minimum of 60 rpm for as long as possible. In analysis, there does not appear to be any significant difference in Rated Perceived Exertion (RPE) values, time to fatigue and maximum resistance. However, the lactate curve was shifted such that the rise in blood lactate levels is delayed when subjects consumed carbonated beverages."

The presentation fulfill a portion of the requirements for the Washburn Transformational Experience opportunity, for which McKee must demonstrate excellence in scholarly and creative activity, community service, leadership or international education. The WTE was established to provide baccalaureate students with the opportunity to make a difference to others or society through enhanced learning designed to complement traditional college studies.

The Apeiron allows students from all disciplines to present their work in an environment that closely resembles the professional conferences and performance venues of their chosen area of study.  Seventy-one students are participating in the forum and entries include poster presentations, oral presentations, exhibitions and performances. To learn more, please visit
