Effect of Core Stability Exercise Versus Whole Body Vibration in Improving Vitamin D Absorption in Women

Woman was in crook lying position with feet flat on the treatment table. The therapist put his two thumbs on the anterior superior iliac spines then, asked the woman to contract the abdominal muscle, hold the contraction for 10 seconds, then, asked her to relax for 10 seconds

The woman assumed a full squat position on a vibration platform. The apparatus was set at a frequency of 30 Hz, amplitude of 2 mm, and duration of 5 min. The women were instructed to remain in the squatting position with holding hand rail after turning on the vibration and to report any discomfort that might arise. At the end of 5 min, the vibration turned off automatically. Thereafter, the women took a 1-min rest. They were then asked to stand on the vibration platform for 5 min, with the same parameters as those used in the squatting position. Thus, the total time for the application of WBV in each session was 10 min
