Concurrent Aerobic and Strength Training with Caloric Restriction Reduces Insulin Resistance in Obese Premenopausal Women: A Randomized Controlled Trial

Background and Objectives: Obese premenopausal women are at high risk of developing insulin resistance (IR). Concurrent aerobic strength training (CAST) has been shown to provide remarkable advantages, yet its effects, along with caloric restriction in such a high-risk population, not established. This study aimed investigate the impact concurrent (CAST-CR) on IR obese women. Materials Methods: Forty-two reported IR, aged 40–50 years, were randomly allocated either intervention group, who underwent CAST restriction, or (AT-CR) control received addition restriction. Both groups completed 12 weeks controlled equivalent time. Aerobic began 60% gradually progressed achieve 75% maximum heart rate, while was executed 50% 70% one-repetition (1RM). Anthropometric measures, abdominal adiposity, metabolic parameters, homeostasis model assessment-estimated (HOMA-IR) evaluated prior following intervention. Results: experienced substantial enhancement selected parameters compared baseline (p < 0.001), higher improvement within CAST-CR group. The changes HOMA-IR −1.24 (95%CI, −1.37 −1.12) group vs. −1.07 −1.19 −0.94) AT-CR Conclusions: While improved sensitivity hyperinsulinemic, calorie more significantly, suggesting it as preferable alternative.
