Trial Outcomes & Findings for The Effects of Exercise on Dietary Intake (NCT NCT00943436)

Results Overview

Energy intake was measured by weighing each item served in the ad libitum buffet meal before and after the subject's meal and subtracting the difference to determine gram weight of each item consumed. Food labels and the NDS-R software were used to determine dietary intake based upon gram weight of each food consumed.

Participant Flow

20 male students attending the University of Tennessee were recruited to participate through ads and flyers posted around campus. The recruitment period started in November 2008 and ended in August 2009 upon completion of the study. The initial phone screen conducted to determine eligibility occurred in the HEAL lab.

Participants were randomly assigned to which session, exercise or rest, they engaged in first. As this is a crossover design, participants did complete both the exercise and rest conditions.
