| Abstrakt: | Blood pressure (BP) assessment during resistance exercise can be useful to avoid high BP, reducing cardiovascular risk, especially in hypertensive individuals. However, non-invasive accurate technique for this purpose is not available. The aim of this study was to compare finger photoplethysmographic (FPP) and intra-arterial BP values and responses during resistance exercise. Eight non-medicated hypertensive subjects (5 males, 30-60 years) were evaluated during pre- exercise resting period and during three sets of the knee extension exercise performed at 80% of 1RM until fatigue. BP was measured simultaneously by FPP and intra-arterial methods. Data are mean±SD. Systolic BP was significantly higher with FPP than with intra-arterial: at pre-exercise (157±13 vs. l52±10mmHg; p<0.01) and the mean (202±29 vs. 198±26mmHg; p<0.01), and the maximal (240±26 vs. 234±16mmHg; p<0.05) values achieved during exercise. The increase in systolic BP during resistance exercise was similar between FPP and intra-arterial ( +73±29 vs. +71±18mmHg; p = 0.59). Diastolic BP values and increases were lower with FPP. In conclusion, FPP provides similar values of BP increment during resistance exercise than intra-arterial method. However, it overestimates by 2.6±6.1% the maximal systolic BP achieved during this mode of exercise and underestimates by 8.8 ±5.8% the maximal diastolic BP. [ABSTRACT FROM AUTHOR] |
