Hybrid neuromuscular training improves cardiometabolic health and alters redox status in inactive overweight and obese women: A randomized controlled trial

Abstract

This randomized controlled trial investigated the effects of a 5-month high-intensity hy-brid-type neuromuscular training program with nontraditional implements on cardiometabolic health, redox status, and cardiovascular disease (CVD) risk in inactive overweight and obese women. Forty-nine inactive female participants with overweight and obesity (age: 36.4 ± 4.4 years; BMI: 29.1 ± 2.9 kg/m2) were randomly assigned to either a control (C, n = 21) or a training group (TR, n = 28). TR followed a 20-week supervised, progressive, time-efficient (3 days/week; 6–15 min net exercise time) program implementing loaded fundamental movement patterns with prescribed work-to-rest time intervals (20–40 s, 1:2, 1:1, 2:1) in a circuit fashion (2–3 rounds). Cardiometabolic risk factors were measured at baseline and post-training as secondary outcomes of a larger randomized controlled trial. At post-intervention, TR demonstrated favorable changes in resting heart rate (−7%, p = 0.043), high-density lipoprotein (+18.1%, p = 0.029), atherogenic index (−17%, p = 0.045), mean arterial pressure (−4.5%, p = 0.03), waist circumference (−6.2%, p = 0.005), waist-to-hip ratio (−4.6%; p = 0.015), metabolic syndrome severity score (−222%, p = 0.024), full 30-year CVD risk (−15.8%, p = 0.002) and hard 30-year CVD risk (−17.6%, p = 0.01), vascular age (−7.8%, p = 0.002), protein carbonyls (−45.7%, p = 0.001), catalase activity (+15.2%, p = 0.023), and total antioxidant capacity (+11.4%, p = 0.002) relative to C. Additionally, TR induced beneficial changes in fasting glucose (−3.4%, p = 0.002), homeostatic model assessment for insulin resistance (−15.7%, p < 0.001), di-astolic blood pressure (−5.6%, p < 0.001), reduced glutathione (+39.8%, p < 0.001), 10-year CVD risk (−17.4%, p = 0.011), and total bilirubin (−21.7%, p < 0.001) compared to baseline. These results suggest that hybrid-type neuromuscular training may improve aspects of cardiometabolic health and anti-oxidant status in inactive overweight and obese women providing a time-efficient (∼100 min/week) exercise approach in a real-world gym setting. © 2021 by the author.
