Effects of autoregulated and non-autoregulated blood flow restriction on vastus medialis oblique responses during low-load resistance exercise
Introduction/purposeBlood flow restriction (BFR) training is a viable strategy for inducing muscle hypertrophy and strength gains using low external loads. This study investigated the acute effects of autoregulated BFR (AR-BFR) and non-autoregulated BFR (NAR-BFR) using the Delfi Personalized…

Cardiovascular, perceptual, and performance responses to single- vs. multi-chambered blood flow restriction cuffs
IntroductionThis study aimed to investigate the impact of the blood flow restriction bladder type (single- [SC-BFR] vs. multi-chambered [MC-BFR]) on exercise performance, cardiovascular responses, and perceptual experiences with exercise sessions incorporating multiple sets to volitional failure in…

Beneath the cuff: Often overlooked and under-reported blood flow restriction device features and their potential impact on practice—A review of the current state of the research
Training with blood flow restriction (BFR) has been shown to be a useful technique to improve muscle hypertrophy, muscle strength and a host of other physiological benefits in both healthy and clinical populations using low intensities [20%–30% 1-repetition maximum (1RM) or <50% maximum oxygen…

Challenges in upright limb occlusion pressure determination with the Delfi PTS: pilot data from two independent cohorts
PurposeBlood flow restriction (BFR) exercise prescription relies on accurate determination of limb occlusion pressure (LOP), which is known to vary by body position. While recent guidelines suggest assessing LOP in the same position as the intended exercise, the feasibility of upright LOP…

Acute safety, cardiovascular, perceptual and neuromuscular responses to autoregulated and non-autoregulated blood flow restriction training during elbow rehabilitation in people with hemophilia
IntroductionLow-load resistance training with concurrent blood flow restriction (BFR) provides strength and hypertrophy benefits to healthy individuals and some clinical populations. This is the first study assessing safety and physiological responses of autoregulated (AUTO) and non-autoregulated…

Fiber-Type-Specific Hypertrophy with the Use of Low-Load Blood Flow Restriction Resistance Training: A Systematic Review
Emerging evidence indicates that the use of low-load resistance training in combination with blood flow restriction (LL-BFR) can be an effective method to elicit increases in muscle size, with most research showing similar whole muscle development of the extremities compared to high-load (HL)…

Acute effect of low-load resistance exercise with blood flow restriction on oxidative stress biomarkers: A systematic review and meta-analysis
Background: The purpose of this review was to analyze the acute effects of low-load resistance exercise with blood flow restriction (LLE-BFR) on oxidative stress markers in healthy individuals in comparison with LLE or high-load resistance exercise (HLRE) without BFR. Materials and methods: A…

Does Protocol Matter for Repetition Volume? A Meta-Analytic Investigation of Volitional Failure Versus the Traditionally Used 75-Repetition Blood Flow Restriction Resistance Training
Abstract Background It is recommended to prescribe sets to volitional muscular failure (e.g., 4 sets) or a fixed repetition scheme of 75 repetitions (1 × 30, 3 × 15) in low-load resistance exercise with blood flow restriction (BFR-RE). While prior studies suggest both protocols may elicit similar…

Physiological adaptations and myocellular stress in short-term, high-frequency blood flow restriction training: A scoping review
Background: High frequency (1–2 times per day) low-intensity blood flow restriction (BFR) training has been recommended as a prescription approach for short durations of time to maximize relevant physiological adaptations. However, some studies demonstrate negative physiological changes after short…

Autoregulation during blood flow restricted exercise offers no additional benefit on thigh muscle hypertrophy and strength adaptations in trained participants: a randomized within-subject 8-week trial
BackgroundWith the increasing use of BFR, various cuff design features have emerged, potentially influencing training outcomes. One notable feature is autoregulation, which dynamically modifies tourniquet cuff pressure during muscle contractions to maintain a consistent applied…

Impact of blood flow restriction cuff design on upper body exercise: A randomized crossover trial in resistance‐trained adults
Abstract Differences in cuff blood flow restriction (BFR) bladder design (single‐chambered [SC‐BFR] and multi‐chambered [MC‐BFR] systems) may influence exercise performance, perceptual responses, and cardiovascular outcomes. In a randomized cross‐over design, twenty‐six healthy physically active…
