Abstract
This study was conducted to determinethe efficacy of core exercise training on improving muscle mass and physical performance in postmenopausal sarcopenic women. Forty postmenopausal women with sarcopenia diagnosed clinically by gynecologist were selected from the gynecology and physical therapy outpatient clinics at El-Sahel Teaching Hospital. Their age ranged from 55 to 65 years and body mass index (BMI) was >30 kg/m². They were randomly distributed into two equal groups: Control group received low caloric diet (1200 kcal/day) for 3 months and encouraged to do physical activity in the form of walking for 30mins 3 times/week, and study group received the same low caloric diet (1200 kcal/day) for 3 months as well as physical activity in the form of walking for 30mins 3 times/week in addition to core exercises for 3 sessions/week for 3 months. Dietary program was modified every week for all women in both groups. Assessment of all women in both groups was carried out before and after the end of the treatment program (3months) through assessment of weight, BMI, waist circumference, waist/hip ratio, muscle mass, gait speed, hand grip and chair stand. Results: The control group showed significant difference in comparing pre and post results of BMI, waist circumference, muscle mass, gait speed, hand grip and chair stand. While waist hip ratio showed non-significant difference in comparing pre and post results.The study group showed significant difference in comparing pre and post result of BMI, waist circumference, waist/hip ratio, muscle mass, gait speed, hand grip and chair stand while comparing between both groups in post treatment results showed non-significant difference in all parameters except hand grip.Conclusion:Low caloric diet and physical activity are beneficial in the health care management ofsarcopenic obese postmenopausal women as they have a positive effect on BMI, muscle mass and physical performance. Adding core exercises to low caloric diet and physical activity showed only a significant effect on increasing physical performance
