The purpose of this study was to examine the effects of walking at different speeds and elevation versus completing a neurocognitive task on end-tidal carbon dioxide (ETCO2) and respiratory rate (RR) in a healthy population. Eleven healthy participants completed the Immediate Post-Concussion Assessment and Cognitive Test (ImPACT) battery and walked on a treadmill under four conditions (slow versus fast walking and uphill versus downhill). A CapnoTrainer was used to measure ETCO2 and RR during the tasks. Statistically significant increases were observed in RR (t(10)=5.52, p=.001) during the ImPACT; ETCO2 (F(4,7)=14.18, p=.002) during all four walking trials; and RR (F(4,7)=7.02, p=.01) during the last three walking trials. Therefore, future investigations using a similar methodology and protocol are warranted in a concussed population.
