Hemodynamic and Pressor Responses to Combination of Yoga and Blood Flow Restriction

Abstract

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.

Assessment of Arterial Stiffness Using the Cardio-Ankle Vascular Index – What We Know and What We Strive for

“…Неудивительно, что воздействия, снижающие уровень стресса, способны снизить CAVI. Так, на фоне выполнения упражнений йоги при сочетании упражнений на растяжку и техник расслабления, показатель артериальной жесткости и CAVI значительно снизились (p<0,01) [48]. Считается, что релаксация и медитация, характерные для йоги, могут привести к уменьшению жесткости артерий и улучшению эндотелий-зависимой вазодилатации за счет снижения тонуса симпатических вазоконстрикторов [48].…”

Stimulation of the Vascular Endothelium and Angiogenesis by Blood-Flow-Restricted Exercise

“…There are multiple definitions of BFR, which include different types of occlusive tools that result in different influences on the vessels and muscles [ 26 ]. The degree of compression spread from 50 mmHg [ 27 ] up to even 300 mmHg [ 6 ]. In most of the studies, the compression was set fixed, and not related to the systolic and diastolic blood pressure of the participants.…”

“…The range of BFRE exercises includes low-intensity as well as high-intensity workloads and varies in multiple different types of exercise, such as walking, running, cycling, weight lifting, hand grip, yoga, or cross-training [ 5 , 6 , 7 ]. Multiple studies have reported that BFRE induces hypoxic stress in skeletal muscles which causes muscle hypertrophy and increases not only muscle strength but also endurance [ 8 , 9 ].…”

The Impacts of Combined Blood Flow Restriction Training and Betaine Supplementation on One-Leg Press Muscular Endurance, Exercise-Associated Lactate Concentrations, Serum Metabolic Biomarkers, and Hypoxia-Inducible Factor-1α Gene Expression

“…Moreover, and despite the apparent non-significant enhancements in HIF-1A gene expression, it is nevertheless possible that we constrained our investigation to a single target. Although the former was chosen as a more encompassing metabolic adaptive mediator, it would be sensible to further assess other relevant genes such as those involved in fiber type alteration and/or lactate-specific metabolism that already have mechanistic rationale within the BFR-associated literature [ 2 , 3 , 8 , 67 , 68 ]. The combination of BFR exercise and betaine supplementation may overall have untried applications amidst a more broad genetic target range, possibly further elucidating the divergent role of HIF-1 within BFR-associated adaptations.…”
