Key result
A single bout of endurance exercise, but not resistance exercise, caused an acute decrease in brachial artery endothelial function (interaction P<0.001), which was unaffected by 4 weeks of chronic exercise training.
Why the study?
Does exercise modality (endurance vs. resistance) and 4 weeks of chronic training alter the acute effect of exercise on brachial artery endothelial function in healthy young men?
RCT (n=34)
Randomised, balanced cross-over
No
Does exercise modality (endurance vs. resistance) and 4 weeks of chronic training alter the acute effect of exercise on brachial artery endothelial function in healthy young men?
Endurance exercise, but not resistance exercise, causes an immediate decrease in brachial artery endothelial function, which is not mitigated by 4 weeks of chronic exercise training.
Acute modality-specific endothelial responses are hypothesis-generating; should not yet inform exercise prescriptions or guidelines.
We found that resistance and endurance exercise modalities lead to different endothelial function responses after a single bout of exercise. Endothelial function increased after an acute bout of resistance exercise, whereas it decreased after an acute bout of endurance exercise. Four weeks of chronic exercise training did not affect the acute endothelial function response.

Boidin et al. (2021) conducted an RCT in Healthy (n=34). Endurance exercise vs. Resistance exercise (4 sets of 10 repetitions leg extension) was evaluated on Acute change in brachial artery flow-mediated dilation (FMD) after a single bout of exercise (p=<0.001). A single bout of endurance exercise, but not resistance exercise, caused an acute decrease in brachial artery endothelial function (interaction P<0.001), which was unaffected by 4 weeks of chronic exercise training.
