I-Group A (control group):

All post-menopausal women followed an energy-restricted diet for 8 weeks. Meal plan that creates an energy deficit of 500 to 1000 Kcal per day less than the individual's average daily intake was suitable for weight reduction.Each post-menopausal woman followed Dietary Approaches to Stop Hypertension (DASH) which : low in total fat, cholesterol, red meat, sweets and sugar containing beverages, emphasize fish, nuts, fruits, vegetables and whole grains and it also rich in Potassium(6900mg), Calcium(1200-1500mg) and Magnesium, as well as vitamins A, C and E.

For 8 weeks, WBV participants completed 3 supervised training sessions a week. Each participant received an explanation of the WBV device and the treatment protocol. Women stood in upright position and hold on handle bar before switching the WBV device at "on" position.

The exercises were consisted of dynamic squats starting from upright position into the assigned degree of knee flexion "squats with 90° knee angle, semi-squats with 120° knee angle" and heel elevation (calf-raise), each exercise was performed for 3 sets and each set consisted of 5 repetitions. All dynamic exercises were performed with slow controlled movements and between each set, there was resting period during which women assumed upright standing position for 1 minute. Total duration of the training session was 30 minutes.
