Abstract/OtherAbstract:
OBJECTIVES: This study is designed toinvestigate the inducing effect of one arm exercise on interarm difference (IAD) in the blood pressure (BP). METHODS: Fifty healthy young participants were included in the study. Three-minute exercises of the right arm elbow flexion and extension were performed. The bilateral brachial BP was simultaneously measured with two automatic BP measurement devices before (basic) and immediately 0, 5, 10, 15, 20, and 30 min after exercise. The absolute difference in the systolic BP (SBP) and diastolic BP (DBP) between the left and right BP of at least 10 mmHg was recognized as sIAD and dIAD. RESULTS: The baseline data of the SBP and DBP in left and right arms revealed no significant difference (SBP: 110±10 vs. 111±11 mmHg; DBP: 66±8 vs. 66±9 mmHg, both not significant). The prevalence of dIAD was 2% at the baseline. However, this prevalence increased to 80% at 0 min, as right arm exercise induced the right DBP decrease and left DBP increase, and then the prevalence decreased gradually within a 30-min recovery period. The prevalence of sIAD was zero at the baseline and the maximal prevalence was 8% during the 20-min postexercise period. CONCLUSION: One arm exercise can lead to a significant IAD in DBP. Any arm exercise should be avoided before BP measurement.
