Acute Responses in Blood Flow Restriction Low-intensity Aerobic Training: A Meta-analysis
Int J Sports Med DOI: 10.1055/a-2038-3635The purpose was to determine the effect low-intensity training with blood flow
restriction (LI-BFR) versus high-intensity aerobic training (HIT) on acute
physiological and perceptual responses. The Cumulative Index to Nursing and
Allied Health Literature, National Library of Medicine, Scopus, SPORTDiscus and
Web of Science databases and the reference list of eligible studies were
consulted to identify randomized experimental studies, published until July 4,
2022, that analyzed physiological or perceptual responses between LI-BFR versus
HIT in healthy young individuals. Mean difference (MD) and standardized mean
difference (SMD) were used as effect estimates and random effects models were
applied in all analyses. Twelve studies were included in this review. During
exercise sessions, HIT promoted higher values of heart rate (MD=28.9
bpm; p<0.00001; I

=79%), oxygen
consumption (SMD=4.01; p<0.00001;
I

=83%), ventilation
(MD=48.03 l/min; p=0.0001;
I

=97%), effort (SMD=1.54;
p=0.003; I

=90%) and blood
lactate (MD=3.85 mmol/L; p=0.002;

=97%). Perception of
pain/discomfort was lower in HIT (SMD=−1.71;
p=0.04; I
