PMID 37266365WHAT IT FOUND
Short-term whole-body vibration training did not improve muscle strength, balance, or body composition in healthy young adults.
The results were identical to floor-based training and no training, suggesting this brief intervention offers no advantage over conventional exercise.
Key findings
01There were no significant differences in lower-extremity muscle strength, balance performance, or body composition between the whole-body vibration group, the floor training group, and the control group at any time point.
02The study found no change in muscle strength, balance, or body composition after the first two weeks of training, after a two-week rest period, or after a second two-week training block.

What it does not show
The study population consisted only of healthy, young university students, so results may not apply to older adults, clinical populations, or those with existing balance or strength deficits. The intervention was short-term (six weeks total), which may not be sufficient to detect structural or metabolic changes. The authors noted that training intensity and frequency were not standardized across previous literature, and they assessed isometric strength using isokinetic equipment, which may have missed specific adaptations. The sample size was small (seven participants per group), reducing the statistical power to detect small but clinically meaningful differences.
Declared interests
The authors declared no conflicts of interest and stated that no funding was granted for this research.
The easy way to misread this
Do not conclude that whole-body vibration is ineffective for all populations or over longer durations. This study only tested short-term effects in healthy young adults using a specific isometric protocol, so it does not rule out benefits for older adults, patients with disabilities, or different training regimes.
