Exercise does not cause an arm–leg blood pressure gradient in healthy children

Any delay in obtaining the BP is, therefore, not representative of the peak SBP or, if two limbs are being compared, any SBP difference between them. [...]in the immediate post-exercise period, the delay in obtaining the leg BP with the Dinamap system would result in a spurious BP gradient between t...

Summary:Any delay in obtaining the BP is, therefore, not representative of the peak SBP or, if two limbs are being compared, any SBP difference between them. [...]in the immediate post-exercise period, the delay in obtaining the leg BP with the Dinamap system would result in a spurious BP gradient between the arm and the leg. To minimise any delays, we exercised our subjects on a recumbent cycle ergometer instead of a treadmill. [...]the method used by Swan et al 4 incorporated at least two major sources of delay in obtaining the BP.
