Correction
After publication of our paper [1], we discovered that our
normalized blood velocity and compliance numbers were
60 times higher than they should have been. The revised
Figure 1 and Figure 2, along with Table 1 are shown here
with the correct values. Heart rate, blood pressure, and
half time to recovery of blood flow and oxygen saturation
from the original article are all correct. The statistical analysis and interpretation of the data remain unchanged. We
apologize for the error.
Figure 1 maximal blood flow for aging effects on left and activity effects on right (Means ± SD)
Normalized
Normalized maximal blood flow for aging effects on left and activity effects on right (Means ± SD). Young is the sum of young
active (YA) and young inactive (YI). Older is sum of older active (OA) and older inactive (OI). Active is sum of young active
(YA) and older active (OA). Inactive is sum of young inactive (YI) and older inactive (OI). & Active and inactive groups are significantly different at p < 0.001.

Conductance of normalized maximal blood flow for aging effects on left and activity effects on right (Means ± SD). Young is the
sum of young active (YA) and young inactive (YI). Older is sum of older active (OA) and older inactive (OI). Active is sum of
young active (YA) and older active (OA). Inactive is sum of young inactive (YI) and older inactive (OI). * Young and older
groups are significantly different at p = 0.003. & Active and inactive groups are significantly different at p = 0.002.
