Description
Summary:Background. Performing resistance exercise could lead to an increase in arterial stiffness. Objective. We investigate the acute effect on arterial stiffness by performing Valsalva manoeuvre during resistance exercise. Materials and Methods. Eighteen healthy young men were assigned to perform bicep curls by using two breathing techniques (exhalation and Valsalva manoeuvre during muscle contraction) on two separate study days. Carotid pulsed wave velocity (cPWV) was measured as an indicator to reflect the body central arterial stiffness using a high-resolution ultrasound system, and its value was monitored repeatedly at three predefined time intervals: before resistance exercise, immediately after exercise, and 15 minutes after exercise. Results. At the 0th minute after resistance exercise was performed using the Valsalva manoeuvre during exertion, a significant increase in cPWV (4.91 m/s ± 0.52) compared with the baseline value (4.67 m/s ± 0.32, P = 0.008 ) was observed, and then it nearly returned to its baseline value at the 15th minute after exercise (4.66 m/s ± 0.44, P = 0.010 ). These findings persisted after adjusting for age, body mass index, and systolic blood pressure. Conclusion. Our result suggests short duration of resistance exercise may provoke a transient increase in central arterial stiffness in healthy young men.
