Abstract: Strength training plays an important role in cardiovascular prevention and rehabilitation. Studies showed inconsistent chronic and acute effects of strength training on arterial stiffness as an emerging biomarker of vascular health. Using pulse wave analysis, the arterial stiffness can be quantified by calculating the pulse wave velocity (PWV). The present study compared acute effects of three strength training protocols on arterial stiffness. 41 healthy, physically active subjects (age 23.8±2.3 yr, height 1.78±0.1 m, body weight 72.9±9.0 kg, body mass index 22.9±2.0 kg/m2) were assigned to three groups: group 1: 30% one repetition maximum (1RM), 3x30 repetitions, group 2: 50% 1RM 3x20 repetitions, group 3: 70% 1RM, 4x10 repetitions. All groups completed a resistance exercise session with five dynamic exercises. Pulse wave velocity (PWV), central diastolic (cDBP) and central systolic blood pressure (cSBP) were measured at rest, 0, 5 and 10 minutes after the training session with a pulse wave analysis system. PWV and cSBP showed an increase after resistance training in group 1 and 2 (p 0.05). cDBP decreased in all groups 5 and 10 minutes after training compared to 0 minutes after training. These results indicate that resistance exercise with low, moderate and high intensities reduce cDBP 5 and 10 minutes after a training session, but only those protocols with lower load and more repetitions acutely increase arterial stiffness in healthy subjects.
