A combination of yoga and blood flow restriction, each of which elicits marked pressor responses, may further increase blood pressure and myocardial oxygen demand. To determine the impact of a combination of yoga and blood flow restriction on hemodynamic responses, twenty young healthy participants performed 20 yoga poses with/without blood flow restriction bands placed on both legs. At baseline, there were no significant differences in any of the variables between the blood flow restriction and non-blood flow restriction conditions. Blood pressure and heart rate increased in response to the various yoga poses (p<0.01) but were not different between the blood flow restriction and non-blood flow restriction conditions. Rate-pressure products, an index of myocardial oxygen demand, increased significantly during yoga exercises with no significant differences between the two conditions. Rating of perceived exertion was not different between the conditions. Blood lactate concentration was significantly greater after performing yoga with blood flow restriction bands (p=0.007). Cardio-ankle vascular index, an index of arterial stiffness, decreased similarly after yoga exercise in both conditions while flow-mediated dilation remained unchanged. In conclusion, the use of lower body blood flow restriction bands in combination with yoga did not result in additive or synergistic hemodynamic and pressor responses.
瑜伽和血流限制的结合，每一种都会引起明显的升压反应，可能会进一步增加血压和心肌耗氧量。为了确定瑜伽和血流限制的结合对血流动力学反应的影响，20 名年轻健康的参与者在双腿上放置血流限制带的情况下进行了 20 个瑜伽姿势。在基线时，血流限制和非血流限制条件之间的任何变量都没有显著差异。血压和心率因各种瑜伽姿势而升高（p<0.01），但在血流限制和非血流限制条件之间没有差异。心率-血压乘积，心肌耗氧量的指标，在没有明显差异的情况下在瑜伽运动中显著增加。两种情况下的感知用力评分没有差异。在使用血流限制带进行瑜伽运动后，血液乳酸浓度显著升高（p=0.007）。在两种情况下，瑜伽运动后，心血管踝血管指数，动脉僵硬的指标，下降幅度相似，而血流介导的扩张保持不变。总之，在瑜伽运动中使用下肢血流限制带并没有导致附加或协同的血流动力学和升压反应。
