Implication

Supports CRAE for BP, arterial stiffness, and insulin resistance improvements in obese prehypertensive adolescent girls; extends RCT evidence to this population.

Key Points

  • The study aims to evaluate the effects of combined resistance and aerobic exercise training on blood pressure, arterial stiffness, and insulin resistance in obese prehypertensive adolescent girls.
  • Forty girls aged 15 ± 1 years were randomly assigned to exercise (n=20) or control (n=20) groups.
  • The exercise group engaged in combined resistance and aerobic exercise for 12 weeks, three times per week.
  • Measures included blood pressure, baPWV, HOMA-IR, and body composition before and after the intervention.
  • Blood pressure decreased by ∆-7.3 ± 2.67 mmHg in the EX group (P < 0.05).
  • Arterial stiffness (baPWV) improved by ∆-1.23 ± 0.49 m/s (P < 0.05).
  • HOMA-IR reduced by ∆-1.4 ± 0.07 in the EX group (P < 0.05).
