Abstract
To test the effect of adding virtual reality exercises versus high volume resistance training to low calorie diet on body fat and blood biomarkers in obese adult females. Design: A single blinded, parallel groups randomized controlled trial.Material and Methods: Sixty adult obese females their age ranged from 40-60 years old and had a body mass index from 30-40 Kg/m2recruited from outpatient clinics of Kasr Al-Ainy Hospital, randomly assigned into 3 equal groups. group (I) received virtual reality exercises plus low calorie diet, group (II) received high volume resistance training plus low calorie diet, and group (III) received low calorie diet only. The intervention was received as 3 sessions a week for 12 weeks. Primary outcome measures were lipid profile, glycated hemoglobin, C-reactive protein, percentage of body fat and trunk fat. Secondary outcome measurements were waist hip ratio, skinfold thickness, quality of life, fatigue severity. All measurements were taken at baseline and after 12 weeks of intervention
Results: After 12 weeks of intervention, there were no statistically significant differences between group (I) and group (II) in all outcome measurements (P>0.05). However, both groups (I) and (II)showed superiority to group (III) in all outcome measures (P<0.05). After 12 weeks of intervention the mean±SD of Total Cholesterol and percentage of body fat were 185.75±28, 43.19±3.61respectively in virtual reality group, 194.9± 26.45, 43.63± 2.19 respectively in high volume resistance training group and 218.65± 33.22, 46.89± 4.03 respectively in control group.
Conclusion: Obese adult females who received virtual reality exercises or high volume resistance training combined with low calorie diet had better improvement, regarding lipid profile, glycated hemoglobin, C- reactive protein, percentage of body fat, trunk fat, waist to hip ratio, skinfold thickness, quality of life, and fatigue severity than participants who received low calorie diet only. Consequently, virtual reality exercises can be a part of obesity management as an enjoyable alternative to traditional exercises, especially when added to low calorie diet.
