Abstract
Background: Prediabetes is a high-risk metabolic state that can lead to poor cardiorespiratory fitness, functional deficits of lower extremities, surplus body fat, and high risk of type 2 diabetes. BFR is a lower-force exercise that may offer a beneficial exercise-training strategy for patients with high-force-intolerant mechanical loads. Objective: This study compared two-months of BFR training with conventional training on VO2 max, function, strength of quadriceps, training-volume, oxygen pulse, and body composition in prediabetics. Methods: A two-month randomized controlled trial was performed in gyms and fitness centers within Faisalabad. The 25–50 year-old, 40 prediabetics were divided into an experimental BFR group (n=20) or a control Conventional group (n=20). Exercise outcomes (VO2 max using Rockport Fitness Walking Test, functional status using the 6-Minute Walk test, strength of quadriceps by use of isokinetic dynamometer, training-volume using daily log, oxygen pulse by using a Heart rate/oximetry reading, body composition by using anthropometrics) were compared before and after the trial. Results: No differences were present at baseline. Post-trial BFR-trained group was better than the conventional-trained group in VO2 max (34.002.34 vs. 32.192.90 ml/kg/min; p=.036), 6-min walk distance (472.8713.13 vs. 445.6526.58m; p<.001), quadriceps strength (30.741.83 vs. 26.832.61; p<.001), training-volume (3.950.76 vs. 3.290.48; p=.002), oxygen pulse (14.750.87 vs. 12.721.55; p<.001), percentage of body fat (25.482.63% vs. 27.542.67%; p=.018), and body mass index (25.052.25 vs. 26.652.38 kg/m2; p=.036). Conclusion: BFR training led to a better increase in VO2 max, functional ability, strength of quadriceps, exercise tolerance, cardiovascular efficiency, and body composition than conventional training in prediabetics.
