Consequently, brachial artery mean blood flow shows a biphasic pattern, with a decrease at lower exercise intensities and an increase in blood flow at higher exercise intensity levels ( 92 , 93 ).

WebAt rest a person's cardiac output is approximately 5 litres per minute, while during exercise it can increase to as much as 30 litres per minute as both their heart rate and stroke … WebDuring an acute bout of resistive exercise, the increase in oxygen uptake and cardiac output is small, at least partially because perfusion of the exercising muscles is difficult as a result of high intramuscular pressures. The heart rate increase is also small. Blood pressure increases markedly as a result of increased total peripheral resistance.
