مقایسه تأثیر لرزش عمومی بدن به‌تنهایی و توأم با تمرین بر ترکیب بدنی در افراد بزرگسال سالم

Background and purpose: Obesity is one of the health problems, which is a risk factor for cardiovascular diseases. Many studies investigated the effects of using whole body vibration (WBV (with other methods on body composition. However, no study has examined the effect of WBV alone on body composition. The aim of this study was to compare the effects of WBV with exercise and WBV alone on body composition in young healthy adults. Materials and methods: This clinical trial was conducted in 390 healthy adults, who were obese or overweight. The samples were randomly divided into three groups of WBV alone, WBV with exercise, and control. The intervention was carried out three times a week for 12 weeks. The control group received no intervention. The body composition indices were measured before and after the intervention. Data analysis was performed using parametric tests in SPSS, version 18. P-values less than 0.05 were considered statistically significant. Results: Compared to the control group, significant reductions were noted in the mean scores for body composition, body fat percentage (BFP), body mass index (BMI), and weight in the intervention groups (P<0.001). However, these indices were not significantly different between the intervention groups (P=0.554). Additionally, the mean changes of the waist-hip ratio did not show a significant difference between the three groups (P=0.574). Conclusion: WBV and WBV with exercise could reduce BFP, BMI, and weight; there was no specific difference between the two methods. Thus, WBV alone can affect body composition in young healthy adults.
