We hypothesized that forearm blood flow (FBF) during moderate intensity dynamic exercise
would meet the demands of the exercise and that postexercise FBF would quickly recover. In …

The vascular strain is very high during heavy handgrip exercise, but the intensity and
kinetics to reach peak blood flow, and peak oxygen uptake, are uncertain. We included 9 …

We used an exercise paradigm with repeated bouts of heavy forearm exercise to test the
hypothesis that alterations in local acid-base environment that remain after the first exercise …

To evaluate the local circulatory changes that accompany chronic localized work, we studied
the effects of a 4-wk handgrip work protocol on maximal forearm work-related blood flow (ml …

The present study examined the onset and the rate of rise of muscle oxidation during intense
exercise in humans and whether oxygen availability limits muscle oxygen uptake in the …

This study tested the effects of sympathetically mediated changes in blood flow to active
muscles on muscle O2 uptake (VO2) in humans. Four minutes of graded (15-80% of …

To test the hypothesis that sex influences forearm blood flow (FBF) during exercise, 15
women and 16 men of similar age [women 24.3±4.0 (SD) vs. men 24.9±4.5 yr] but different …

Hypoxia during exercise augments blood flow in active muscles to maintain the delivery of
O2 at normoxic levels. However, the impact of hyperoxia on skeletal muscle blood flow …

This study compared the brachial artery blood flow (Q̇ BA) and microvascular oxygen
delivery responses during handgrip exercise above vs. below critical force (CF; the isometric …
