Key result
Blood flow restriction training resulted in significantly higher muscle activation during the last 20 contractions compared to training without restriction, though post-training neuromuscular effects were similar.
Why the study?
Before blood flow restriction training is used in elderly and clinical populations with weakness, it is important to understand its neurological effects and subject perceptions.
Does blood flow restriction training alter neuromuscular responses compared to training without restriction in healthy subjects?
Comparison
BFRT vs training without blood flow restriction (TR-only)
Design
Crossover study with 2 experimental sessions on separate days
Follow-up
20-min-post exercise
Authors

BFRT does not alter post-exercise cortical excitability versus traditional training; leaves open its role in clinical neuromuscular rehabilitation.
RCT (n=17)
Randomly allocated to perform TR or BFRT on the first day
No
Does blood flow restriction training alter neuromuscular responses compared to training without restriction in healthy subjects?
p-value: p=0.009
Blood flow restriction training induces similar post-training neuromuscular fatigue as conventional training but increases muscle activation during exercise, albeit with greater perceived discomfort.
Kjeldsen et al. (2019) conducted an RCT in Healthy (n=17). Blood flow restriction training (BFRT) vs. Training without blood flow restriction (TR-only) was evaluated on Surface EMG amplitude during training (muscle activation) (p=0.009). Blood flow restriction training resulted in significantly higher muscle activation during the last 20 contractions compared to training without restriction, though post-training neuromuscular effects were similar.
