Abstract
Background
Clinically, when a difference of at least 10 mmHg in systolic blood pressure (SBP) between arms exists, it is identified as an interarm systolic blood pressure difference (ISBPD). At rest, ISBPD is linked with hypertension, peripheral vascular disease, and increased premature mortality. Exercise may reveal underlying cardiovascular pathologies otherwise absent at rest. However, there have been no investigations to examine the effect of exercise on ISBPD.
Aim
The aim of this investigation was to determine whether exercise may alter ISBPD when detected at rest or reveal ISBPD when it was not observed in the resting condition.
Methods
An experienced investigator sequentially measured SBP using standard auscultation in each arm (alternating order) in 85 normotensive individuals (22 +/- 6 years, 39 male, 46 female). ISBPD was quantified before exercise (PRE). Participants then completed a three-stage protocol on a cycle ergometer. A cadence of 50 rpm was maintained at a workload of 3 (EX-3; light) and 6 (EX-6; moderate) METS and during an active recovery (REC). At each stage, SBP was measured upon achieving steady-state heart rate. A logistic regression analysis was used to determine the change in odds ratio of ISBPD when exposed
Results
Thirteen percent (<i>n</i> =11) of patients presented with ISBPD during PRE and the degree of ISBPD was lower (3.81 mmHg; <i>P</i> <0.05) in REC than PRE. In individuals who did not present with ISBPD during PRE (<i>n</i> =74), progression from EX-3 to EX-6 significantly increased the odds of developing ISBPD (4.31; <i>P</i> <0.05).
Conclusion
In individuals with ISBPD at PRE, active recovery from exercise attenuated the difference between interarm SBP. Moderate-intensity exercise resulted in ISBPD not otherwise present at rest.
