AbstractThis study determined the influence of walking with blood flow restriction (BFR) on the excess post-exercise oxygen consumption (EPOC) of healthy young men. 17 healthy young men (22.1±2.9 years) performed graded treadmill exercise to assess VO2peak. In a randomized fashion, each participant performed 5 sets of 3-min treadmill exercise at their optimal walking speed with 1-min interval either with or without BFR. Participants were then seated in a chair and remained there for 30 min of recovery. Expired gases were continuously monitored during exercise and recovery. BFR increased the O2 cost of walking as well as its relative intensity and cumulative O2 deficit (p<0.05). The EPOC magnitude after walking with BFR was greater than in the non-BFR condition (p<0.05). No differences between conditions were seen for the duration of EPOC. The EPOC magnitude was no longer different between conditions after controlling for the differences in relative intensity and in the cumulative O2 deficit (p>0.05). These data indicate that walking with BFR increases the magnitude of EPOC. Moreover, they also demonstrate that such increment in EPOC is likely explained by the effects of BFR on walking relative intensity and cumulative O2 deficit.

ABSTRACT Introduction: The literature has shown that a gap is identified regarding the acute effects of blood flow restriction training on aerobic variables. Objective: to analyze oxygen consumption (VO2) during and after two resistance training sessions: traditional high intensity and low intensity with blood flow restriction. Methods: After one-repetition maximum tests, eight male participants (25.7±3 years) completed the two experimental protocols, separated by 72 hours, in a randomized order: a) high intensity training at 80% of 1RM (HIRE) and b) low intensity training at 20% of 1RM combined with blood flow restriction (LIRE + BFR). Three sets of four exercises (bench press, squat, barbell bent-over row and deadlift) were performed. Oxygen consumption and excess post-exercise oxygen consumption were measured. Results: the data showed statistically significant differences between the traditional high intensity training and low intensity training with blood flow restriction, with higher values for traditional training sessions, except for the last five minutes of the excess post-exercise oxygen consumption. Oxygen consumption measured during training was higher (p = 0.001) for the HIRE (20.32 ± 1.46 mL·kg-1·min-1) compared to the LIRE + BFR (15.65 ± 1.14 mL·kg-1·min-1). Conclusion: Oxygen uptakes rates during and after the exercise sessions were higher for the high intensity training methodology. However, when taking into account the volume of training provided by both methods, these differences were attenuated.

The present study aimed to evaluate the acute behavior of the brachial artery resistance index (BARI) and popliteal artery resistance index (PARI) in response to low intensity strength exercises involving small (SMG) and large muscle groups (LMG) performed with and without blood flow restriction. Eleven men (age 23 ± 3.29 years) underwent a four-arm, randomized, cross-over experiment: Small muscle group exercise (SMG), small muscle groups with blood flow restriction (SMG+BFR), large muscle groups (LMG) and large muscle groups with blood flow restriction (LMG+BFR). The behavior of BARI and PARI was evaluated at rest, immediately after exercise, and at 15 and 30 minutes during recovery. Data analysis showed a significant reduction of the BARI from rest to post-exercise only in the protocols involving SMG, regardless of the BFR (p <0.05). Protocols involving LMG, with or without BFR, did not affect PARI (p> 0.05), but were efficient to promote significant increases in BARI (p <0.05) immediately after exercise. Our findings indicate that the exercises involving SMG, regardless of BFR, are efficient to promote local vasodilatation (brachial artery), but without systemic effects. None of the analyzed protocols affected the PARI behavior.

Some researchers are concerned that exercise training with the blood flow restriction (BFR) technique induces an exaggeration in blood pressure response and potentiates adverse cardiovascular events. In the present study, we demonstrate that the blood pressure response to arm-curl exercise was intensified by the BFR technique, and the degree of intensification was associated with a blood pressure response to post-exercise muscle ischemia of the elbow flexors, which elicit a muscle metaboreflex. Novelty bullet Blood flow restriction technique intensifies blood pressure response to exercise, which was associated with a blood pressure response in post-exercise muscle ischemia-induced muscle metaboreflex.

The purpose of this study was to determine acute physiological and perceptual responses to two commonly implemented blood flow restriction protocols. Using a within-subject design, 15 participants (age ∼25) performed four sets of unilateral elbow flexion with each arm. One arm exercised using a 3-cm elastic cuff inflated to 160 mmHg, whereas the other arm exercised using a 5-cm nylon cuff inflated to 40% of the individual’s arterial occlusion pressure. While both protocols elicited increases in acute muscle thickness [pre: 4.5 (0.2) cm, post: 5.0 (0.2) cm; p < 0.001] and electromyography amplitude [first 3 reps: 55 (5) %MVC; last 3 reps: 87 (10) %MVC], there were no differences between conditions. Both protocols produced decreases in post-exercise strength (pre: 70 Nm, post: 51 Nm; p < 0.001) with no difference between conditions. The nylon protocol resulted in more repetitions during sets 2 [13 (2) vs. 9 (4); p = 0.001] and 3 [10 (2) vs. 7 (4); p = 0.05], while producing lower levels of discomfort following each set (average 3 vs. 4; p < 0.05). In conclusion, both protocols produced similar acute responses thought to be important for promoting muscle growth. However, the use of arbitrary pressures may place some individuals under complete arterial occlusion which may increase the potential risk of an adverse event.

Aim: This study examined the effect of aerobic exercise with and without blood flow restriction on exercise-induced hypoalgesia and endogenous opioid and endocannabinoid systems. Methodology: In a randomised crossover design, pain-free individuals performed 20 min of cycling in four experimental trials: 1) Low intensity aerobic exercise (LI-AE) at 40% V̇O2max; 2) LI-AE with low pressure BFR (BFR40); 3) LI-AE with high pressure BFR (BFR80); and 4) High intensity aerobic exercise (HI-AE) 70% V̇O2max. Pressure pain thresholds (PPT) were assessed before and 5 min post-exercise. Circulating concentrations of beta-endorphin and 2-arachidonoylglycerol were assessed before and 10 min post-exercise. Results: In the exercising legs, post-exercise PPTs were increased following BFR40 and BFR80 compared to LI-AE (23-32% vs 1-2%, respectively). Post-exercise PPTs were comparable to HI-AE (17-20%) with BFR40 and greater with BFR80 (30-32%). Both BFR80 and HI-AE triggered comparable systemic hypoalgesia in remote areas of the body (26-28% vs 19-21%). Post-exercise circulating beta-endorphin concentration was increased following BFR40 (11%) and HI-AE (14%, with the greatest change observed following BFR80 (29%). Post-exercise circulating 2-arachidonoylglycerol concentration was increased following BFR40 (22%) and BFR80 (20%), with the greatest change observed following HI-AE (57%). Conclusion: Addition of BFR to LI-AE can trigger both local and systemic hypoalgesia that is not observed follow LI-AE alone and activate endogenous opioid and endocannabinoid systems of pain inhibition. Compared to HI-AE, local and systemic hypoalgesia following LI-AE with high pressure BFR is greater and comparable, respectively. LI-AE with BFR may help pain management in load compromised individuals.

Background: It has been assumed that during and after BFR exercises, many blood factors are activated and angiogenesis response is stimulated in the arteries. Objectives: Therefore, the current study aimed to determine the effect of two eccentric resistance training methods with and without blood flow restriction on serum IL6 and MMP9 levels in active young men. Methods: In this quasi-experimental study, 16 healthy men with a mean age of 27.8 ± 2.85 (years), the weight of 79.4 ± 12.4 (kg), and a body mass index of 25.5 ± 3.7 (kg/m2) were randomly assigned to either low-intensity eccentric group with BFR or the high-intensity eccentric without BFR. The high-intensity (70% - 80% maximum voluntary contraction MVC) eccentric exercise without BFR included 3 - 5 cycles of eccentric contraction of the quadriceps muscles, up to exhaustion, whereas low-intensity eccentric exercise executed similar exercise modality at intensity of 20% - 30% MVC with blood flow restriction up to exhaustion. Blood samples were taken from antecubital both before and after the exercise to measure serum IL6 and MMP9 values using the ELISA method. Data were analyzed using paired t-test and analysis of variance with repeated measure test in SPSS version 22. A P value of < 0.05 was defined as statistically significant. Results: High-intensity resistance per se and low-intensity resistance exercise with BFR similarly resulted in a non-significant reduction of IL-6 and elevated levels of MMP-9 serum levels in active young men. Conclusions: Overall, the results indicated that a low-intensity resistance exercise session with restricted blood flow and a high-intensity resistance exercise without blood flow restriction equally did not affect IL6 and MMP9 serum of active young men. Further studies are needed to clarify the exact exercise modality that sufficiently stimulates angiogenesis.
