Blood-Flow Restriction Walking: Effects on Insulin Sensitivity and Aerobic Capacity in Type 2 Diabetes

Abstract

Background: Type 2 Diabetes (T2D) is a prevalent global health issue requiring effective management strategies. Exercise plays a key role in improving insulin sensitivity and aerobic capacity. This study examines the impact of Blood-Flow Restriction (BFR) Walk Training on these parameters in T2D patients, hypothesizing that BFR may offer greater benefits than conventional exercise.

Objectives: To evaluate the effects of BFR Walk Training on insulin sensitivity, aerobic capacity, and body composition in male patients with T2D.

Methods: A randomized controlled trial was conducted with 60 male T2D patients aged 40 to 65. Participants were randomly assigned to a BFR Walk Training or conventional exercise group. The intervention lasted for eight weeks, during which the BFR group performed low-intensity walking combined with limb blood-flow restriction, while the control group followed standard walking exercises. Pre- and post-intervention assessments included Body Mass Index (BMI), maximal oxygen consumption (VO2max), and fasting blood glucose levels.

Results: The BFR group showed significant improvements, including a 4.10% reduction in BMI, a 7.96% decrease in fasting glucose levels, and a 26.1% increase in VO2max, all with p-values <0.001 compared to the control group.

Conclusion: BFR Walk Training significantly enhances insulin sensitivity, aerobic capacity, and body composition in T2D patients, offering a novel and effective exercise strategy for diabetes management.
