![]() ![]() It is evident that the cuff pressure selected during BFR training has the potential to promote different acute ( Clarkson et al., 2020) and chronic ( Slysz et al., 2016 Clarkson et al., 2020) responses. In addition to its use in clinical prevention and rehabilitation settings, RT with BFR may be an alternative method to maximize neuromuscular adaptations without increasing joint stress ( Lixandrao et al., 2018). Therefore, low-load RT with BFR may be an alternative to traditional high-load RT for untrained subjects and populations with severe physical limitations. Results from meta-analyses in healthy and clinical populations demonstrate that RT combined with BFR using 20–30% 1-RM elicits similar changes in muscular endurance, muscular strength, and hypertrophy versus traditional high-load RT ( Slysz et al., 2016 Lixandrao et al., 2018 Centner et al., 2019), and was superior to load-matched RT without BFR in promoting muscle hypertrophy and strength gains ( Slysz et al., 2016). It is evident that intensity ≥70% of the individual one-repetition maximum (1-RM) promotes substantial training adaptations ( American College of Sports Medicine, 2009), while for clinical populations (e.g., patients undergoing rehabilitation or having underlying disease) and untrained adults, RT with such high loads may be difficult to apply ( Clarkson et al., 2020).īlood flow restriction (BFR) is an emergent training method which uses a cuff placed at the proximal portion of the exercising limb to restrict venous outflow in working musculature ( da Cunha Nascimento et al., 2020). RT intensity is generally considered as one of the most important variables for developing muscular adaptation ( American College of Sports Medicine, 2009). Resistance training (RT) increases muscular strength, power, muscle mass, functional capacity, sports performance, and general health ( American College of Sports Medicine, 2009). In addition, RT with total BFR promoted similar responses of oxidative stress and markers of immune cell apoptosis versus traditional RT. Results: Data indicated that all training groups showed similar increases in muscular strength ( p 0.05).Ĭonclusion: Data show that RT with partial BFR can increase muscular strength but still does not augment biomarkers of oxidative stress in untrained men. Blood samples were obtained before and after the first and last training sessions. Over an 8-week period, participants performed six sets of arm curls until failure with 90 seconds of recovery for 3 days/week. Methods: Twenty-seven untrained men were randomly divided into three groups: traditional RT, RT with partial (20% 1-RM), and total BFR (20% 1-RM). Purpose: The present study compared changes in acute oxidative stress and markers of apoptosis in immune cells before and after 8 weeks of low-load RT with total or partial blood flow restriction (BFR) versus high-load traditional RT. Introduction: The characterization of immune and oxidative stress responses to acute and chronic exercise training is important because it may aid in the safety and dose–response prescription of resistance training (RT) in many populations. 4Physical Education Research Laboratory, Universidade Cidade de São Paulo, São Paulo, Brazil.3Graduation Program on Physical Education, Catholic University of Brasilia, Brazilia, Brazil.2Department of Kinesiology, California State University San Marcos, San Marcos, CA, United States. ![]() 1Interdisciplinary Post-graduate Programme in Health Sciences, Cruzeiro do Sul University, São Paulo, Brazil.Fabio Rocha de Lima 1† Douglas Popp Marin 1†‡ Letícia Torres Ferreira 1 Celso Pereira Batista Sousa Filho 1 Todd Anthony Astorino 2‡ Jonato Prestes 3‡ Marcelo Luis Marquezi 4‡ Rosemari Otton 1*‡
