How does low-load blood flow restriction (LL-BFR) training influence muscle mass and strength in older adults compared to conventional resistance training, and what is the effectiveness of walking with and without BFR?
Blood Flow Restriction Cuffs, a systematic review and meta-analysis in 238 participants (Sports Med 2019, PMID 30306467) — adding BFR to low-load training and walking significantly improved muscular strength, with pooled effect sizes of 2.16 and 3.09, respectively. The BFR literature is still scarce regarding potential moderator variables such as sex, cuff pressure, or training volume/frequency, indicating a need for further research.

Low-load resistance training and walking combined with blood flow restriction effectively increase muscle mass and strength in older adults, with similar hypertrophy but lower strength gains compared to high-load training.
The question
How does low-load blood flow restriction (LL-BFR) training influence muscle mass and strength in older adults compared to conventional resistance training, and what is the effectiveness of walking with and without BFR?
What they tested
The study aims to quantitatively identify the effects of LL-BFR training on muscle mass and strength in older individuals.
How they did it
A PRISMA-compliant systematic review and meta-analysis was conducted. Electronic databases (PubMed, Web of Science, Scopus, CINAHL, SPORTDiscus, CENTRAL) were searched until June 1, 2018. A random-effects meta-analysis with inverse variance weighting was performed on 11 included studies with a total of 238 participants.
What they found
Adding BFR to low-load training and walking significantly improved muscular strength, with pooled effect sizes of 2.16 and 3.09, respectively. Muscle mass also increased when comparing walking with and without BFR (ES 1.82). Compared to high-load training, LL-BFR promoted similar muscle hypertrophy (ES 0.21) but resulted in lower strength gains (ES -0.42).
| LL Training + BFR (Strength) | 2.16 | |
|---|---|---|
| Walking + BFR (Strength) | 3.09 | |
| Walking + BFR (Muscle Mass) | 1.82 | |
| LL-BFR vs High-Load (Hypertrophy) | 0.21 | |
| LL-BFR vs High-Load (Strength) | -0.42 |
Effect sizes (ES) for various comparisons of low-load blood flow restriction (LL-BFR) training and walking with BFR on muscle strength and hypertrophy in older adults.
What it means
LL-BFR and walking with BFR are effective interventions for stimulating muscle hypertrophy and strength gains in older populations.
Limitations
The BFR literature is still scarce regarding potential moderator variables such as sex, cuff pressure, or training volume/frequency, indicating a need for further research.

Blood Flow Restriction Cuffs
Meta-analyses of randomized trials show that low-load resistance training with blood flow restriction increases muscle strength and size more than the same light loads without occlusion, and produces muscle hypertrophy comparable to heavy-load training, although heavy loads still tend to yield somewhat greater gains…
Blood flow restriction (BFR) training pairs low-load exercise (typically 20-40% of one-repetition…
