Blood flow regulation and oxygen uptake during high-intensity forearm exercise

SK Nyberg, OK Berg, J Helgerud… - Journal of applied …, 2017 - journals.physiology.org
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 …

Blood flow and muscle oxygen uptake at the onset and end of moderate and heavy dynamic forearm exercise

MCP Van Beekvelt, JK Shoemaker… - American Journal …, 2001 - journals.physiology.org
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 …

Prolonged ischaemia impairs muscle blood flow and oxygen uptake dynamics during subsequent heavy exercise

A Faisal, KS Dyson, RL Hughson - The Journal of physiology, 2010 - Wiley Online Library
