Key result
Walk training with blood flow restriction significantly altered triglycerides and fibrinogen, and increased red blood cell levels in overweight middle-aged men (p ≤ 0.05).
Why the study?
To investigate the effects of walk training with and without blood flow restriction on lipid profiles, inflammatory, and haematological factors in overweight middle-aged men.
Does walk training with lower-body blood flow restriction improve lipid profiles, inflammatory markers, and hematological indices in overweight middle-aged men compared to walk training without blood flow restriction?
RCT (n=18)

p-value: p=≤0.05
Walk training with blood flow restriction over 8 weeks alters lipid, inflammatory, and hematological profiles in overweight middle-aged men, suggesting potential physiological benefits for populations at risk of metabolic syndrome.
BFR-augmented walking was associated with TG and fibrinogen changes in overweight men; hypothesis-generating and should not yet change practice.
The objective of present study is to investigate the effects of walk training with and without blood flow restriction (BFR and no-BFR) on lipid profiles, inflammatory and haematological factors in over-weighed men. Participants were divided into BFR (n = 9) or no-BFR (n = 9) groups. Both groups were exposed to 8-week walk training on a treadmill: 3 sessions/week at a speed of 50 m/min, 5 sets × 2 min/session. There were differences in pre- to post-levels of (TG) and fibrinogen in the BFR group (p ≤ 0.05) that were accompanied by changes in red blood cells (RBC), haemoglobin (HGB) and haematocrit (HCT) levels (p ≤ 0.05). RBC levels were increased in the BFR group (p ≤ 0.05). The groups differed in their mean corpuscular volume (MCV) and mean corpuscular haemoglobin concentration (MCHC). These findings suggest the efficiency of BFR walk training in individuals exposed to chronic diseases associated with overweight, such as metabolic syndrome.

Razi et al. (2021) conducted an RCT in Overweight (n=18). Walk training with blood flow restriction (BFR) vs. Walk training without blood flow restriction (no-BFR) was evaluated on Lipid profiles, inflammatory and haematological factors (p=≤0.05). Walk training with blood flow restriction significantly altered triglycerides and fibrinogen, and increased red blood cell levels in overweight middle-aged men (p ≤ 0.05).
