Effect of breath-hold on the responses of arterial blood pressure and cerebral blood velocity to isometric exercise

Purpose The present study examined the effect of breath-hold without a Valsalva maneuver during isometric exercise on arterial blood pressure (ABP) and cerebral blood flow (CBF). Methods Twenty healthy adults (15 men and five women) randomly performed only breath-hold without a Valsalva maneuver (BH...

Description
Summary:Purpose The present study examined the effect of breath-hold without a Valsalva maneuver during isometric exercise on arterial blood pressure (ABP) and cerebral blood flow (CBF). Methods Twenty healthy adults (15 men and five women) randomly performed only breath-hold without a Valsalva maneuver (BH), and an isometric handgrip exercise for 30 s at 40% of individual maximal voluntary contraction with continuous breathing (IHG) and with breath-hold without the Valsalva maneuver (IHG–BH). Mean ABP (MAP) and blood velocity in the middle (MCA V mean ) and posterior cerebral arteries (PCA V mean ) were continuously measured throughout each protocol. Results MAP was elevated during the IHG–BH compared with IHG ( P
