Key result
Low-intensity walking with blood flow restriction produced similar oxygen consumption to walking with a 15% body mass load (p=0.202).
Why the study?
The study aimed to evaluate exercise with blood flow restriction as a low-intensity conditioning strategy for tactical professionals with load carriage.
Does low-intensity walking with blood flow restriction produce similar acute metabolic responses to walking with load carriage in healthy adult males?

p-value: p=0.202
Low-intensity walking with blood flow restriction produces acute metabolic responses similar to walking with a load, suggesting its potential as a conditioning strategy.
BFR walking may elicit metabolic responses comparable to load carriage in tactical trainees; leaves open long-term efficacy and safety in prospective trials.
International Journal of Exercise Science 16(2): 304-314, 2023. The current study aimed to investigate exercise with blood flow restriction (BFR) as a low-intensity conditioning strategy in tactical professionals with load carriage. During the low-intensity exercise, researchers examined the acute metabolic responses from low-intensity BFR walking, walking with load carriage, and walking with BFR and load carriage. Twelve healthy adult males (age = 21.8 ± 1.5 yrs, height = 181.3 ± 7.2 cm, body mass = 84.4 ± 11.1 kg and BMI = 25.6 ± 2.6 kg.m2) completed five bouts of 3-min treadmill walking at 4.8 kmh-1 with 1-min rest interval under three different conditions: 1) blood flow restriction (BFR), 2) loaded with 15% of body mass (LOAD) and 3) loaded with 15% of body mass with blood flow restriction (BFR-LOAD). Oxygen consumption (O2), heart rate, and local muscle oxygen saturation was measured during the exercise bouts. O2 increased by 7% during the BFR- LOAD (p = 0.001) compared with BFR or LOAD alone. There were no differences in O2 between BFR and LOAD (p = 0.202). BFR-LOAD showed significantly lower (-9%) muscle oxygen saturation (p = 0.044) and deoxygenated hemoglobin (p = 0.047) compared to LOAD. Low-intensity walking with the addition of BFR shares acute metabolic characteristics similar to walking with a load. These characteristics suggest there is potential for the use of BFR to increase exercise intensity for individuals training with load carriage.

Dicks et al. (2023) studied Healthy (n=12). Blood flow restriction (BFR) walking vs. Walking with load carriage (LOAD) was evaluated on Oxygen consumption (O2) (p=0.202). Low-intensity walking with blood flow restriction produced similar oxygen consumption to walking with a 15% body mass load (p=0.202).
