Acute Inflammatory Responses to Blood Flow Restriction Training: A Systematic Review.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe effects of Blood Flow Restriction (BFR) training are well-established, but its impact on the inflammatory response remains unclear. This systematic review evaluates whether BFR training induces acute inflammation by analyzing changes in inflammatory parameters.
methodsThis review was conducted according to PRISMA guidelines. The literature search was performed across PubMed, Web of Science, BISp-Surf and Google Scholar up to July 2025. Studies were included if they reported acute changes in inflammatory markers within 72 h after BFR training, as well as macrophage presence up to 14 days. Only trials involving healthy adults with inflammatory parameters assessed via peripheral blood or muscle biopsy were considered. Risk of bias was assessed using RoB 2 and ROBINS-I. Standardized mean differences (SMDs) were calculated to quantify within-study changes. In addition, relative percentage changes were calculated to enable a comparison of the magnitude of inflammatory responses across studies. An effect direction plot was created to summarize the direction of inflammatory marker changes (SWiM 2020).
resultsNine studies involving 189 healthy adults were included in the systematic review. Transient increases in total leukocytes (18-33%) and lymphocytes (37-43%) were consistently observed in peripheral blood following exercise. Significant increases in total tissue macrophages (200%) were also reported. Findings on neutrophils (up to + 40%), cytokines (up to + 340%), and lymphocyte subpopulations (TCD4⁺: +25%, TCD8⁺: +39%) varied across studies.
conclusionThe findings suggest that BFR training induces acute inflammation, characterized by transient leukocytosis, lymphocytosis, and increased macrophage activity. However, the variability in neutrophil and cytokine responses, as well as in lymphocyte subsets, may be attributed to variations in training parameters and methodological approaches. Overall, these responses appear comparable to those observed following high-load resistance training (HL-RT). Further research is needed to clarify the underlying mechanisms and their potential contribution to muscle adaptation.
