Acute Effects of Self-myofascial Release using a Foam Roller on Arterial Stiffness in Healthy Young Adults

This study aimed to investigate whether a single bout of Self-myofascial Release (SMR) has a beneficial effect on peripheral and central Blood Pressure (BP) and different parameters of arterial stiffness. Twenty nine healthy male recreational athletes (26.1 +/- 2.9 years, BMI 23.4 +/- 1.5 kg/m(2)) completed an instructed SMR using a foam roller. Peripheral and central BP and different parameters of arterial stiffness were measured noninvasively before SMR and at different time points (t1, t15, t30) during a subsequent 30-min recovery phase. There was a significant decrease in both systolic (t15, -2.36 +/- 4.45 mmHg, p = 0.05; t30, -4.01 +/- 4.47 mmHg, p = 0.003) and diastolic (t30, -2.45 +/- 5.45 mmHg, p = 0.025) peripheral pressure during the recovery phase after SMR. Regarding central BP, only systolic pressure showed a significant decrease (t30, -3.64 +/- 5.83 mmHg, p = 0.003). Mean arterial pressure (t15, -1.91 +/- 3.36, p = 0.03; t30, -3.05 +/- 2.88 mmHg, p < 0.001), augmentation pressure (t30, -1.60 +/- 2.40 mmHg, p = 0.009), peripheral resistance (t30, -0.09 +/- 0.10 s* mmHg/ml, p < 0.001), and stiffness index beta 0 (t30, -0.33 +/- 0.55, p = 0.021) were significantly reduced after SMR. No significant changes were determined for reflection coefficient, augmentation index, cardiac output, and heart rate, respectively. SMR showed effects on peripheral and central BP and different parameters of arterial stiffness in healthy young adults. HIGHLIGHTS A single bout of self-myofascial release confers favourable cardiovascular benefits. Self-myofascial release induces mechanical stress to the vascular system. Effects on vascular function is comparable to the effects after a bout of exercise. (C) 2020 Association for Research into Arterial Structure and Physiology.
