Figure 7

Digital blood flow and recovery times in hypercapnic responders. Digital blood flow (DBF) in arbitrary units (a.u.) and digital blood flow recovery times (DBFR) in seconds (secs) in high (High) and low (Low) hypercapnic responders at baseline and following hot and cold immersion. Results are expressed as mean ± standard error of mean.
