This study examined differences between healthy and concussed participants when performing a neuropsychological and physical task on measures of end-tidal carbon dioxide (ETCO2). Twenty-two participants (17 healthy; 5 concussed) completed the Immediate Post-Concussion Assessment and Cognitive Test (ImPACT) battery and walked on a treadmill at two walking speeds. A CapnoTrainer© measured ETCO2 during the tasks. Statistically significant main effects were observed for task (F(1,20)=5.332, p<0.032; F(2,38)=52.305, p<0.001) and group (F(1,20)=14.388, p<0.001; F(1,19)=8.283, p<0.01) in ETCO2 during the cognitive and physical tasks, respectively. Abnormal ETCO2 levels may occur after concussion, therefore, future investigations are warranted.
