PROTOCOL

Testing occurred at the Campbell County Senior Center (Highland Heights, KY) or the Abilene Christian University Human Performance Laboratory (Abilene, TX). Participants completed the testing visits in a randomized, crossover fashion. Participants were not given information as to which trial was being completed. At each respective location, the same researchers conducted all experimental visits, including meal preparation and measurements. A diagramatic representation of the protocol can be seen in Figure \ref{459616}.
Participants were informed to report to each testing session having fasted for a minimum of 3 hours. Each testing session for a given participant was conducted at the same time throughout the study. A minimum of 48 hours separated each trial. All participants completed the testing visits within a two-week time span. A subset of participants completed a third, control arm, also within the two weeks.
