Blood flow restriction exercise (BFRE) similarly combines bouts of blood flow restriction with low-intensity exercise and thus could potentially emulate the protection demonstrated by RIPC. One concern with BFRE, however, is the potential for an augmented rise in sympathetic outflow due to greater activation of the exercise pressor reflex. Because of the use of lower workloads, however, we hypothesized that BFRE would elicit an attenuated increase in sympathetic outflow [assessed via plasma norepinephrine (NE) and mean arterial pressure (MAP)] and middle cerebral artery velocity (MCAv) when compared with conventional exercise (CE). Fifteen subjects underwent two leg press exercise interventions: 1) BFRE-220 mmHg bilateral thigh occlusion at 20% 1 rep-max (1RM), and 2) CE-65% 1RM without occlusion. Each condition consisted of 4 \u00d7 5-min cycles of exercise, with 3 \u00d7 10-reps in each cycle. Five minutes of rest and reperfusion (for BFRE) followed each cycle. MAP increased with exercise ( P &lt; 0.001) and was 4\u20135 mmHg higher with CE versus BFRE ( P \u2264 0.09). Mean MCAv also increased with exercise ( P &lt; 0.001) and was higher with CE compared with BFRE during the first bout of exercise only ( P = 0.07). Plasma NE concentration increased with CE only ( P &lt; 0.001) and was higher than BFRE throughout exercise ( P \u2264 0.02). The attenuated sympathetic response, combined with similar cerebrovascular responses, suggest that cyclical BFRE could be explored as an alternative to CE in the clinical setting.<\/jats:p>","DOI":"10.1152\/ajpregu.00112.2017","type":"journal-article","created":{"date-parts":[[2017,8,24]],"date-time":"2017-08-24T00:40:22Z","timestamp":1503535222000},"page":"R507-R517","source":"Crossref","is-referenced-by-count":13,"title":["Cyclical
