^*Population averages are presented with standard deviations for the peak, mean flow rates, and total hyperemic flow volume, along with the time to peak and hyperemic peak width at the three tested postlabeling delays (PLDs). Except for time to peak and hyperemic duration, the number in brackets is the ratio of mean of each flow measure to the mean flow measure in forearm flexors.
