What is the predominant resonant frequency range affecting the spine in whole-body vibration?

1-2 Hz
2.5-5.0 Hz
20-30 Hz
100-200 Hz

The correct answer is: 2.5-5.0 Hz

The predominant resonant frequency range affecting the spine in whole-body vibration is between 2.5-5.0 Hz. This range is considered to be most impactful for the human body, as it falls within the range of natural frequencies of the spine. Option A (1-2 Hz) may also have some effect on the spine, but it is not the predominant range. Option C (20-30 Hz) and D (100-200 Hz) are both significantly higher frequencies, and therefore, have less impact on the spine compared to the lower frequencies. These frequencies may still have some effect on other parts of the body, but are not the predominant ranges affecting the spine.
