Effect of Aerobic Exercise Associated With Resistance Training on Body Composition of Middle-Aged and Elderly Women

Abstract

Introduction: Lack of exercise negatively impacts physical condition and quality of life among middle-aged and elderly women. Objective: Study the effects of aerobic exercise combined with strength training on the body composition of middle-aged and elderly women. Methods: The exercise was performed once every other day from 5 pm to 6 pm. 20 middle-aged and elderly women formed an experimental group. The exercise consisted of aerobic exercise combined with strength training, while the control group practiced aerobic walking. The entire experiment lasted two months, having a total of 30 sessions. Results: Body fat percentage in the experimental group decreased from 35.10±3.436% to 30.07±3.104 %; BMI decreased from 24.98±2.870 kg/m² to 24.25±3.251 kg/m²; the mean bone mineral density increased from 1.20±0.284 g/cm3 to 1.21±0.278 g/cm3. Conclusion: Aerobic exercise and resistance training can improve physical function in middle-aged and elderly women. It may also improve bone density, optimize sports practice, and promote women’s physical health. Level of evidence II; Therapeutic studies - investigating treatment outcomes.
