Combined exercise training reduces blood pressure, arterial stiffness, and insulin resistance in obese prehypertensive adolescent girls

Abstract Background The aim was to verify the effect of non-periodized and linear periodized combined (aerobic plus resistance) exercise training on insulin resistance markers in adults with obesity. Methods A blinded randomized control trial was conducted with three groups of individuals with obesity (BMI, 30–39.9 kg/m2): control group (CG, n = 23), non-periodized group (NG, n = 23), and linear periodized group (PG, n = 23). The NG and PG performed aerobic and resistance exercises in the same session in aerobic-resistance order for 16 weeks. Both intervention groups trained three sessions weekly, with a total duration of 60 min each. The aerobic training of the NG had a duration of 30 min always between 50% and 59% of the reserve heart rate (HRres), while resistance exercise was comprised of 6 exercises, performed always in 2 × 10–12 maximum repetitions (MRs). The PG progressed the aerobic and resistance training from 40%–49% to 60%–69% (HRres) and from 2 × 12–14 to 2 × 8–10 RM, respectively, along the intervention period. The evaluated indicators of insulin resistance included fasting glucose, fasting insulin, and homeostasis model assessment-estimated insulin resistance (HOMA-IR) collected pre- and post-intervention. The analyses to verify the exercise training effect were performed using generalized estimating equations. Results After 16 weeks of training, per protocol analysis (n = 39) showed significant reductions in HOMA-IR only in the training groups (NG: Δ = − 1.6, PG: Δ = − 0.6; p = 0.094). Intention-to-treat analysis demonstrated significant reductions in fasting insulin levels (NG: Δ = − 1.4, PG: Δ = − 1.0; p = 0.004) and HOMA-IR (NG: Δ = − 5.5, PG: Δ = − 3.8; p = 0.002). Conclusion Periodized and non-periodized combined exercise training similarly reduces insulin resistance markers in adults with obesity.

MethodsWas conducted a blinded randomized controlled trial with three groups of individuals with obesity (BMI, 30–39.9kg/m²): control group (CG, n=23), non-periodized group (NG, n=23), and linear periodized group (PG, n=23).

Both intervention groups trained three sessions weekly, with total duration of 60 minutes each. The aerobic training of the NG had duration of 30 min always between 50%–59% of the reserve heart rate (HRres), while resistance part was compost of 6 exercise, performed always in 2×10–12 maximum repetitions (RM).

Combined Exercise Training

Physical exercise and isoflavone supplementation are potential strategies to prevent and treat cardiovascular diseases in postmenopausal women. The aim of this study was to investigate whether there are additive effects of isoflavone supplementation when associated with combined aerobic and resistance exercise on resting and ambulatory blood pressure monitoring (ABPM) and in blood pressure variability (BPV). Thirty-one non-obese postmenopausal women were randomly allocated into two groups: placebo and exercise (Placebo n = 19); and isoflavone supplementation (100 mg/day) and exercise (isoflavone n = 19). ABPM and BPV were evaluated before and after 10 weeks of moderate combined (aerobic and resistance) exercise training. Generalized Estimating Equation (GEE) with Bonferroni correction and intention-to-treat analysis was used to compare the effects of interventions on resting BP, ABPM and BPV. Combined exercise training decreased resting systolic (SBP) and diastolic blood pressure (DBP) and reduced 24 h and awake ambulatory SBP, DBP and mean blood pressure over time, with no additional effects of isoflavone supplementation. No changes were observed in sleep period, or in BPV indexes (Standard Deviation of 24 h (SD), daytime and nighttime interval (SDdn) and average real variability (ARV) in both groups. We conclude that isoflavone supplementation does not potentiate the effects of combined training on resting and ambulatorial systolic and diastolic blood pressure in non-obese postmenopausal women.
