Key result
Low-load resistance exercise with blood flow restriction increased p38MAPK phosphorylation at 2 hours (1.3 vs 0.4; p=0.05) and enhanced mRNA expression of VEGF and PGC-1α compared to control.

Does low-load resistance exercise with blood flow restriction improve angiogenic signalling in males?
Absolute Event Rate: 1.3% vs 0.4%
p-value: p=0.05
Acute low-load resistance exercise with blood flow restriction provides a targeted angiogenic response, potentially mediated through enhanced ischaemic and shear stress stimuli.
Ferguson et al. (2018) studied this question. Low-load resistance exercise with blood flow restriction vs. Low-load resistance exercise without blood flow restriction was evaluated on p38MAPK phosphorylation at 2 hours post-exercise (p=0.05). Low-load resistance exercise with blood flow restriction increased p38MAPK phosphorylation at 2 hours (1.3 vs 0.4; p=0.05) and enhanced mRNA expression of VEGF and PGC-1α compared to control.
