Key result
Whole body vibration with blood flow restriction acutely increased von Willebrand factor levels by 17.2% more than WBV alone (p<0.05), but both groups showed equal decrements after 8 weeks.
Why the study?
Blood flow restriction exercise improves muscle performance, but there is limited research on vascular dysfunction, particularly when combining an involuntary muscle contraction modality with blood flow restriction.
Does whole body vibration combined with blood flow restriction affect von Willebrand factor levels in physically inactive men compared to whole body vibration alone?

Warrants caution with acute BFR addition to WBV; confirms equivalent chronic vascular benefits with or without BFR in inactive men.

Does whole body vibration combined with blood flow restriction affect von Willebrand factor levels in physically inactive men compared to whole body vibration alone?
Effect estimate: 17.2% higher increase
p-value: p=< 0.05
While adding blood flow restriction to whole body vibration acutely increases markers of vascular dysfunction, 8 weeks of training with or without blood flow restriction yields similar improvements in vascular function in inactive men.
Lin et al. (2019) conducted an RCT in Physically inactive (n=16). Whole body vibration (WBV) with blood flow restriction (BFR) vs. Whole body vibration (WBV) alone was evaluated on von Willebrand factor (vWF) levels (17.2% higher increase, p=< 0.05). Whole body vibration with blood flow restriction acutely increased von Willebrand factor levels by 17.2% more than WBV alone (p<0.05), but both groups showed equal decrements after 8 weeks.
