Impact of Multicomponent Training Frequency on Health and Fitness Parameters in Postmenopausal Women: A Comparative Study.

BACKGROUND

Menopause induces physiological changes in women, including increased risks of obesity, cardiovascular diseases, and muscle loss, which can be mitigated by physical exercise. This study aimed to evaluate the effects of a 12-week multicomponent exercise programme, performed 2 or 3 days per week, on health and fitness parameters in postmenopausal women.

METHODS

Eighty-three postmenopausal women (aged 50-65 years) were randomly assigned to three groups: control group (CG, = 27), 2 days/week exercise group (EG2, = 28), and 3 days/week exercise group (EG3, = 28). The intervention included strength, balance, aerobic, and flexibility exercises. Anthropometric measurements (body weight, BMI, waist-to-hip ratio, lean body mass, body fat percentage), lipid profile, and isometric strength were assessed pre- and post-intervention. Data were analysed using a repeated-measures ANOVA, with < 0.05 considered significant.

RESULTS

Significant reductions in body weight, BMI, and waist-to-hip ratio were observed in EG2 and EG3 compared to CG. Lean body mass increased significantly in both EG2 ( < 0.001, ES = 1.37) and EG3 ( < 0.001, ES = 1.50). EG3 showed a greater reduction in body fat percentage than EG2 ( = 0.049). Strength and balance improved significantly in both experimental groups compared to CG, with no significant differences between EG2 and EG3. EG3 also showed superior improvements in lipid profile compared to EG2 and CG.

CONCLUSION

A multicomponent exercise programme, particularly with higher frequency (3 days per week), improves body composition, strength, balance, and lipid profile in postmenopausal women.
