“…El reclutamiento de fibras musculares típicamente sigue el "principio de tamaño" o de Henneman (Parodi, 2017) en el que las unidades motoras más grandes, que contienen principalmente fibras FT, se reclutan progresivamente a medida que aumenta la carga de entrenamiento para la generación de un mayor torque muscular (Vopat et al, 2020). De esa manera en nuestro estudio se puede observar aumentos en la frecuencia de disparo de las unidades motoras y la amplitud de los picos en consonancia con un mayor reclutamiento de las unidades motoras FT (Tegtbur et al, 2020). Estos resultados pueden ser atribuibles a la fatiga muscular, que puede alterar la activación de la unidad motora y el reclutamiento secuencial de las fibras musculares según lo dicta el principio de tamaño (Yasuda et Otro potencial beneficio tendría relación con el reintegro deportivo, donde se lo asociaría a un menor riesgo de lesión al ser los sujetos sometidos a cargas más bajas lo que implica un menor estrés para el tejido miotendinoso y el sistema nervioso central, pero manteniendo capacidades de adaptación similares a las logradas con el entrenamiento tradicional (Lineo & Choi, 2021).…”

Introduction: Blood Flow Restriction Training (BFRT), combines exercise and partial blood flow reduction with positive effects on the development of muscle hypertrophy. However, there is still a marked inconsistency in the effects it generates on the development of muscle power. Objective: This study aims to analyze the effect of upper extremity vascular occlusion training on muscle power in trained adults. Methods: Quasi-experimental study with control group in 12 subjects, mean age 28 (± 1.3) years. Purposive, non-probabilistic sampling. Divided into two groups; i) intervened group, which performed an BFRT protocol at 30% of 1 repetition maximum (1RM); ii) traditional training group, performed training at 70% of 1RM. Each group performed 12 bench press training sessions. Results: BFRT increased mean power (p = 0.01); concentric power (p = 0.04) and eccentric power (p = 0.01). Discussion: El EOV mostró mejoras en potencia muscular, lo que se condice por lo reportado en la literatura en otras poblaciones. Se debe considerar que la presión de oclusión debe ser adaptada para cada participante para evitar riesgos en la salud. Conclusion: 12 sessions of low-load muscular strength training with vascular occlusion improve the muscular power of the upper extremities in the bench press exercise in a sample of trained adults. Introducción: El entrenamiento con oclusión vascular (EOV), combina ejercicio y reducción parcial del flujo sanguíneo con efectos positivos sobre el desarrollo de la hipertrofia muscular. Sin embargo, sigue habiendo una marcada inconsistencia en los efectos que genera sobre el desarrollo de la potencia muscular. Objetivo: Analizar el efecto del entrenamiento de oclusión vascular en la potencia muscular extremidades superiores de adultos entrenados.

“…After the cerclage was relieved, the blood vessels in the blood flow restricted area were congested for a period of time. This process increased the shear stress of blood vessels and endothelial cells, further stimulated the activation of eNOS and increased the expression of eNOS ( Leung et al, 2008 ; Chantler and Frisbee, 2015 ; Tegtbur et al, 2020 ). At the same time, the expression of eNOS in BFRT myocardium was the highest in the exercise groups, and the phosphorylation level of eNOS was the highest.…”

Objective: The purpose of this study was to explore the effect of blood flow-restricted low resistance training on microvascular rarefaction in the myocardium of spontaneously hypertensive rats (SHRs).Methods: Four-week-old male SHRs were randomly divided into the following groups: Wistar-Kyoto (WKY), SHR control (SHR-SED), high-intensity resistance training (HIRT), low-intensity resistance training (LIRT), and blood flow-restricted low resistance training (BFRT). The exercise groups began to receive exercise intervention for 8 weeks at the age of 7 weeks. Blood pressure (BP), heart rate (HR), cardiac function, capillary density, and Vascular endothelial growth factor -Phosphatidylinositol 3-kinase-Protein kinase B-Endothelial nitric oxide synthetase (VEGF-Pi3k-Akt-eNOS) were assessed.Results: 1) BP and HR of BFRT decreased significantly, Ejection fraction (EF) and Fraction shortening (FS) increased, and the effect of BFRT on lowering BP and HR was better than that of other groups (p < 0.05); 2) The expression of VEGF, VEGFR2, p-VEGFR2, Pi3k, Akt, p-Akt, eNOS and p-eNOS in the myocardium of the BFRT was significantly upregulated, and eNOS expression was significantly higher than other groups (p < 0 05); 3) the expression of VEGF in the blood of the BFRT was significantly upregulated, higher than SHR-SED, lower than HIRT (p < 0.05), and there was no significant difference between BFRT and LIRT(p > 0.05); 4) the capillary density in the myocardium of BFRT was significantly higher than other exercise groups (p < 0 05).Conclusion: Blood flow-restricted low resistance training can activate the VEGF-Pi3k-Akt-eNOS pathway, upregulate the expression of VEGF in blood, improve microvascular rarefaction, and promote myocardial microvascular circulation, thereby improving cardiac function and lowering blood pressure, achieving the preventive effect of early hypertension.

“…All patients in the RR group and RR + BFRT group received routine rehabilitation training from day 2 postoperatively, twice a week for 8 weeks. According to the literature ( Abe et al, 2006 ; Tegtbur et al, 2020 ; Jack et al, 2022 ) and our previous clinical experience, the routine rehabilitation training program was formulated: 1) 5 min warm-up exercise: including self-pulling and free walking-running on the elliptical machine; 2) Active ROM training of the lower extremity: sliding bed exercises for active knee flexion and extension, 10 repetitions per set, 10 s rest between sets, a total of 3 sets; 3) Squat training within the 0–90° motion arc: 10 repetitions per set, 10 s each time, 30 s rest between sets, a total of 3 sets; 4) Walking training for 5 min; 5) The German GYM80 intelligent strength training system was used to perform low-intensity pedaling closed-chain training within the range of motion of the knee joint from 0 to 90°. During muscle contraction, concentric and eccentric contractions alternate in rhythmic cycles of 1 s each.…”

“…Blood flow re-striction training (BFRT) may be a potential strategy to compensate for this deficiency in routine rehabilitation training. BFRT was pioneered by SATO in Japan ( Abe et al, 2006 ), which enables compression of the limb through compression cuffs to reduce arterial inflow and block venous outflow during rehabilitation training ( Tegtbur et al, 2020 ). Jack et al (2022) compared the efficacy of BFRT with conventional rehabilitation in patients after anterior cruciate ligament reconstruction (ACLR).…”

Purpose: To explore the effect of blood flow restriction training (BFRT) on the recovery of knee function in patients after arthroscopic partial meniscectomy (APM).Methods: Forty patients undergoing APM surgery were included in this parallel group, two-arm, single-assessor blinded, randomized clinical trial. The subjects were randomly divided into two groups: routine rehabilitation group (RR Group, n = 20) and routine rehabilitation + blood flow restriction training group (RR + BFRT Group, n = 20). One subject in each group dropped out during the experiment. All patients received 8 weeks of routine rehabilitation starting from the second day after APM. In addition, patients in the RR + BFRT group required additional BFRT twice a week. Visual analogue scale (VAS) score, range of motion (ROM), one-leg standing test (OLST) score, Lysholm knee score, quadriceps muscle strength, quadriceps thickness, and thigh circumference were evaluated at preoperative, postoperative, 4 and 8 weeks after surgery. SPSS 25.0 software was used for statistical analysis of the data. Repeated measures ANOVA was used if the data were normally distributed and had homogeneity of variance. Generalized estimating equations were chosen if the data were not normally distributed or had homogeneity of variance.Results: There were no significant differences in VAS score, ROM, OLST score, Lysholm knee score, quadriceps muscle strength, quadriceps thickness, and thigh circumference between the two groups before surgery (p > 0.05). Compared with postoperative, VAS score, ROM, OLST score, Lysholm knee score, and thigh circumference were significantly improved in the RR group (p < 0.05), while quadriceps muscle strength and quadriceps thickness were not significantly enhanced at 8 weeks postoperatively (p > 0.05). However, VAS score, ROM, OLST score, Lysholm knee score, quadriceps muscle strength, quadriceps thickness, and thigh circumference were all significantly improved in the RR + BFRT group at 8 weeks postoperatively (p < 0.05). Furthermore, compared with the RR group, VAS score (50% vs. 86%), ROM (7.9% vs. 16.0%), OLST score (57.3% vs. 130.1%), Lysholm knee score (38.4% vs. 55.7%), relative peak torque (11.0% vs. 84.7%), mean power (20.6% vs. 88.1%), rectus femoris thickness (0.40% vs. 13.0%), vastus medialis (0.29% vs. 5.32%), vastus lateralis (0% vs. 6.2%), vastus internus (0% vs. 5.8%), and thigh circumference (2.7% vs. 5.8%) in the RR + BFRT group were significantly improved at 4 and 8 weeks postoperatively (p < 0.05).Conclusion: BFRT combined with routine rehabilitation training can better promote the recovery of knee joint function in patients after APM, especially the improvement of quadriceps muscle strength and thickness.
