Abstract
Background and Aim: Paying attention to exercise to improve biochemical, physiological and psychological indices in overweight and obese postmenopausal women is of particular importance. This study aimed to investigate the effect of four weeks of resistance training at home on plasma levels of C-reactive Protein (CRP), body composition indices and self-efficacy in overweight and obese postmenopausal women in Birjand. Materials and Methods: The present study was an applied and quasi-experimental study with a pre-test-post-test design on 56 overweight and obese postmenopausal women (age 45-65 years, BMI ≥25). Participants were randomly divided into Two resistance training groups at home (n=28) and control groups (n=28). The practice group performed resistance training at home for four weeks (28 90-minute sessions of moderate intensity), each session including squats, lunges, standing leg raises, bicep curls, backbends, swimming, Side and back muscles rotation and deadlifts with weights. Before and after training, plasma CRP levels were measured through fasting blood sampling and body composition indices (weight, Body Mass Index (BMI), Waist-to-Hip Ratio (WHR), waist, hip, abdominal, arm, chest, and thigh circumferences). Self-efficacy was also assessed with the standard questionnaire by Scherer et al. (1982). Data were analyzed using analysis of covariance and paired t-test at a significance level p<0/05. Finding: After four weeks of resistance training at home, no significant change was observed in CRP levels; while significant decreases were observed in WHR, chest, hip, arm, thigh, and waist circumferences, but changes in weight, BMI, and abdominal circumference were not significant. Self-efficacy increased in the training group. Conclusion: Resistance training at home can improve the physical and mental health of menopausal women and is recommended as an effective strategy in managing menopausal complications and overweight.
