“…However, the control group performing the same exercises without blood restriction experienced only 8.9% and 1.3% increases in squat and leg curl 1-RM strength, respectively [Abe et al, 2005b]. In another 2-week study of twice-daily training that included three sets of leg curls and squats at 20% 1-RM, the 1-RM squat strength increased by 14% [Yasuda et al, 2005]. Takarada et al (2004) reported a 9.2% increase in isokinetic strength in the knee extensors after an 8-week training program consisting of five sets of knee extension exercises (20% 1-RM) with KAATSU, but the isokinetic strength change in knee extensors in the group performing the same exercises without KAATSU was only 3.1%.…”

“…Additionally, one week of twice-daily KAATSU training consisting of knee extension exercises at 20% of 1-RM resulted in a 3% increase in the quadriceps muscle CSA [Abe et al, 2005a], whereas completion of an 8-week training program that included five sets of knee extension exercises at an intensity of 20% 1-RM with KAATSU resulted in a 10.3% increase in knee extension CSA, but no significant changes in muscle CSA were determined when exercising at the same intensity without blood flow restriction [Takarada et al, 2004]. Finally, Yasuda et al (2005) observed a 7.8% and a 1.8% increase in quadriceps muscle CSA in KAATSU and no-KAATSU groups, respectively, after a 2-week training (at 20% 1-RM) program. Type I and Type II muscle fiber CSA increased 5.9% and 27.6% following KAATSU training, whereas changes in Type I and Type II fiber CSA were -2.1% and 0.5% after no-KAATSU training, respectively.…”

Skeletal muscle adapts to a progressive overload, but the response can vary between different modes and intensities of exercise. Generally, a minimal threshold intensity of 65% of the one repetition maximum (1-RM) is needed to elicit muscle hypertrophy; however, recent studies have challenged this hypothesis and have provided evidence that low-intensity training (LIT) combined with vascular restriction (KAATSU) may also elicit increases in muscle size and strength. The physiological aspects of applying vascular restriction during exercise are not fully understood and may be explained by several factors. Examining the results of previous studies may help elucidate the factors responsible for the adaptations associated with vascular restriction in humans. Therefore, the objectives of this review are to summarize current knowledge regarding the physiological adaptations of skeletal muscle after low-intensity exercise combined with vascular restriction, the different training protocols used to elicit adaptations, and suggested areas for future research.

“…Tais ganhos corroboram com estudos anteriores, os quais dizem que a EENM e a RFS são eficazes no aumento do recrutamento de fibras musculares (3,4). Ao que se sabe até o momento, a associação das duas técnicas nunca foi utilizada para avaliação da atividade neuromuscular e equilíbro dinâmico em atletas de alto rendimento.…”

“…Uma forma de prevenir lesões e otimização da performance esportiva é por meio do treinamento de força associado à estimulação elétrica neuromuscular (EENM), que tem se mostrado um recurso eficiente (2). Outro método que tem se mostrado benéfico no ganho muscular é a associação de treinamento de baixa intensidade e restrição do fluxo sanguíneo (RFS) (3). As pesquisas com a RFS são recentes e necessitam ser melhor exploradas nos esportes de alto rendimento.…”

Resumo: O presente estudo teve o objetivo de analisar a atividade eletromiográfica, durante teste funcional de equilíbrio, em atletas de basquete de alto rendimento, que participaram de um programa de treinamento com a eletroestimulação neuromuscular (EENM), bem como a EENM durante a restrição do fluxo sanguíneo (RFS) de membros inferiores. A pesquisa foi composta por 49 atletas, randomizados e alocados: grupo controle (n=17), EENM (n=16) e EENM+RFS (n=16). O quadríceps foi estimulado bilateralmente três vezes na semana, durante quatro semanas, por uma corrente pulsada, quadrática, bifásica simétrica, com intensidade máxima tolerada. A RSF foi realizada por um manguito de pressão, posicionado na região proximal da coxa. A EENM e RSF, foram realizadas durante um treinamento de flexo/extensão de joelho em cadeira extensora. Para a análise do equilíbrio, foi utilizado o Star Execution Balance Test. Durante esse teste foi realizada a análise eletromiográfica (Trigno™, Delsys® Incorporation, Massachusetts, EUA) do músculo quadríceps femural. As avaliações foram realizadas previamente o primeiro dia de treinamento e após o último dia de treinamento. Para análise estatística, foi utilizado o modelo linear misto, post hoc de Bonferroni, significância de 5% (SPSS 17.0). A EENM com e sem RFS promoveu alterações na atividade eletromiográfica muscular e melhora do equilíbrio de membros inferiores. Conclui-se que a EENM é uma técnica eficaz na melhora do equilíbrio e atividade elétrica muscular em atletas de basquete de alto rendimento.

Abstract:The purpose of this study was to analyze electromyographic activity, during functional balance test, in highperformance basketball athletes who participated in a training program with NMES, as well as NMES during blood flow restriction (BFR) of lower limbs. The study consisted of 49 randomized and allocated athletes: control group (n = 17), NMES (n = 16) and NMES+BFR (n = 16). The quadriceps was stimulated, three times in a week, during 4 weeks by anpulsed, quadratic, symmetrical biphasic current with maximum tolerated intensity. BRF was performed by a cuff positioned in the proximal region of the thigh. ANMES and BRF, knee flexion / extension training was performed in extensor chair. For balance analysis, the Star Execution Balance Test was used. During this test, was done the electromyographic analysis (Trígono ™, Delsys® Incorporation, Massachusetts, USA) of the quadriceps and leg muscles. Evaluations were performed prior to the first day of training and after the last day of training. For statistical analysis, the mixed linear, post hoc Bonferroni model was used, a significance of 5% (SPSS 17.0). NMES with and without BRF promoted changes in electromyographic muscle activity and improvement of lower limb balance. It is concluded that NMES is an effective technique in improving balance and muscular electrical activity. Key-Words: Neuromuscular Electrical Stimula...

“…Actualmente está ganando popularidad un tipo de entrenamiento de la fuerza orientado a incrementar los niveles de hipertrofia que se caracteriza por ejercitarse en condiciones de isquemia con cargas de tan sólo el 20% de 1 RM (Yasuda, Abe, Sato, Midorikawa, Kearns, Inoue, y Ishii, 2005). Las mejoras obtenidas mediante este tipo de entrenamiento han demostrado ser tan efectivas como el entrenamiento con altas cargas (Manimmanakorn, Manimmanakorn, Taylor, Draper, Billaut, Shearman, y Hamlin, 2013).…”

El entrenamiento de fuerza orientado a aumentar la masa muscular se ha convertido en un objetivo común en programas de entrenamiento tanto en deportistas de alto rendimiento como en personas que realizan programas de actividad física con objetivo de mejorar su salud o calidad de vida. Generalmente, el trabajo de fuerza orientado hacia la hipertrofia muscular se ha asociado con la utilización de altas cargas de trabajo (70-85% de 1 RM). Actualmente, se ha propuesto que el entrenamiento de fuerza con cargas de tan solo el 20% de 1 RM realizadas en condiciones de restricción del flujo sanguíneo podría provocar incrementos en los niveles de fuerza y masa muscular similares a los observados al ejercitarse con cargas altas. Dado que ciertos colectivos podrían beneficiarse del empleo de bajas cargas en sus programas de entrenamiento orientados a incrementar la masa muscular, el objetivo del presente trabajo de revisión bibliográfica ha sido el de revisar en la literatura las evidencias que existen en torno a la efectividad del entrenamiento con restricción del flujo sanguíneo a la hora de provocar hipertrofia muscular.Palabras clave: entrenamiento de fuerza; hipertrofia; KAATSU; restricción del flujo sanguíneo. R e s u m e nCorrespondencia/correspondence: Raúl Domínguez Departamento de Actividad Física y Deporte, Universidad Alfonso X El Sabio. España Email: rdomiher@uax.es Strength training focuses on increasing muscle mass has become in a frequent target in training programs in both elite athletes and people performing physical activity programs to improve their health or quality of life. Generally, the resistance training oriented muscle hypertrophy has been associated with the use of high workloads (70-85% of 1RM). Currently, it has been proposed that the resistance training with loads of only 20% 1RM under conditions of restricted blood flow can induce increases in strength levels similar to resistance training with high intensities. Because certain groups could benefit from the use of low loads in their strength training programs designed to increase muscle mass, the objective of the present study was to review the literature on the existing evidence about the effectiveness of blood flow restriction training inducing muscle hypertrophy.Key words: resistance training; hypertrophy; KAATSU; blood flow restriction.
