Preservation of Cognitive Performance with Age during Exertional Heat Stress under Low and High Air Velocity

Figure 1

Rectal temperature ((a) and (c)) and heart rate ((b) and (d)) at the start of the paced auditory serial addition task (PASAT) and averaged over the 3-minute duration of the PASAT when administered at baseline (white), end of the 4th exercise bout (end exercise; grey), and end of the final recovery (end recovery; black) in young and older males under low and high air velocity. Values are mean ± SE. Main effect of time; end exercise and end recovery versus baseline for rectal temperature; end exercise and end recovery versus all time points for heart rate; # main effect of air velocity condition; main effect of age; significant difference between pre-PASAT and PASAT within each air velocity condition and age group.
