We tested the hypothesis that, among conditions of matched contractile work, shorter
contraction durations and greater muscle fibre recruitment result in augmented skeletal …

New Findings What is the central question of this study? In electrically stimulated skeletal
muscle, force production is downregulated when oxygen delivery is compromised and …

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 …

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 …

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 …

Limb blood flow increases linearly with exercise intensity; however, invasive measurements
of muscle microvascular blood flow during incremental exercise have demonstrated …

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 …

The magnitude of the blood flow response to exercise has been linked to both the contractile
work performed and the metabolic cost of the activity. Under certain conditions, contractile …

Key points Critical power represents an important threshold for neuromuscular fatigue
development and may, therefore, dictate intensities for which exercise tolerance is …

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 …
