The aim of this study was to investigate whether in short term whole body vibration (WBV) training and creatine supplementation could affect muscle strength, mobility, and balance in elderly women.
The participants were 22 healthy older women aged 60 years and over, who were randomly divided into the following groups; 1) whole-body vibration and creatine (WBV + Cr), whole-body vibration and placebo (WBV + P), and control group. The whole-body vibration groups performed exercises for 10 days. The intensity, amplitude and work-rest ratio were 30-35 HZ, 5 mm, and 1:1 respectively. From the day 1 to day 5 subjects in WBV + Cr group consumed 20g per day oral creatine supplement. This was followed by consuming 5g of creatine per day for the next 5 days. Subjects in WBV + P group consumed equal amount of dexterous as placebo. To assess mobility performance 30-meter walking and tandem gait tests were applied. Static and dynamic balance measured by Flamingo and Timed-Up and Go (TUG) tests. Muscle isometric and isotonic strength assessed by using dynamometer and leg extension tests.
