The relationship between shear rate and flow‐mediated dilation is altered by acute exercise

Abstract

The weak relationship in FMD and SR after exercise suggests that these data should not be normalized following aerobic exercise. Thus, endothelial function was attenuated after a continuous 30-min aerobic exercise session.

Circuit Resistance Training Attenuates Acute Exertion-Induced Reductions in Arterial Function but Not Inflammation in Obese Women

“…Indeed, such factors have been shown to mediate postexercise FMD responses in various patient populations. 38,[40][41][42] Repetitive increases in flow during habitual exercise training have been shown to improve FMD, which is indicative of enhanced NO-mediated EF. 24,43,44 There is a plethora of research demonstrating that aerobic training enhances EF in overweight and obese adults, 45,46 but few studies have investigated the specific effects of resistance training.…”

Effects of acute and chronic low-volume high-intensity interval exercise on cardiovascular health in patients with coronary artery disease

“…It is important to note that the direction of the FMD change is not consistent between studies, as previous investigations have demonstrated increases (Harris et al 2008;Harvey et al 2005;Tinken et al 2010;Tyldum et al 2009), decreases (Harris et al 2008;Llewellyn et al 2012;McGowan et al 2006;Rognmo et al 2008;Silvestro et al 2002), and no change Harvey et al 2005;Rognmo et al 2008;Silvestro et al 2002) in FMD following an exercise bout. However, the evidence from the 2 within-subject studies suggest exercise duration and intensity may not influence the magnitude of the post-exercise responses, as similar changes in endothelialdependent function were observed within a given sample following different exercise bouts.…”

“…Investigations of the acute endothelial responses to a single bout of exercise have employed a variety of exercise interventions including endurance exercise Harris et al 2008;Harvey et al 2005;Jones et al 2010;Llewellyn et al 2012;Tyldum et al 2009), interval exercise (Tyldum et al 2009), sub-maximal and maximal exercise (Silvestro et al 2002), isometric handgrip exercise (McGowan et al 2006;Tinken et al 2010), and resistance exercise (Phillips et al 2011). Of these investigations, only 2 have compared the effect of different exercise bouts by employing within-subject study designs (Harris et al 2008;Tyldum et al 2009).…”

“…Several studies have examined the acute cardiovascular responses to a single bout of exercise in healthy populations, including indices of arterial stiffness (Heffernan et al 2007;Kingwell et al 1997) and FMD (Harris et al 2008;Llewellyn et al 2012); however, there is limited evidence on the acute cardiovascular responses to exercise in patients with CAD. A few studies have compared the acute responses of steady state (endurance) and interval exercise in CVD populations, which will be in the subsequent section.…”

“…Examinations of the acute brachial artery endothelial responses to a single bout of exercise are plentiful, and have included a variety of populations including healthy individuals (Harvey et al 2005;Jones et al 2010;Llewellyn et al 2012;Phillips et al 2011;Rognmo et al 2008;Silvestro et al 2002;Tinken et al 2010;Tyldum et al 2009), athletes Phillips et al 2011;Rognmo et al 2008), post-menopausal women (Harvey et al 2005), overweight individuals (Harris et al 2008), medicated hypertensives (McGowan et al 2006), and patients with peripheral arterial disease (Silvestro et al 2002). The assessment of endothelial function following a single bout of exercise is relevant because it provides information about the exercise stimulus.…”
