- Whole body-vibration training is known to improve muscle strength, flexibility, circulation, and reduce pain, but its specific effects on artistic gymnasts' flexibility remain unclear.
- A systematic review identified 9 studies involving 210 male and female gymnasts, focusing on flexibility assessments using front splits, sit and reach, and bridge tests, showing improved flexibility percentages.
- The findings suggest that whole-body vibration can enhance flexibility in artistic gymnasts and may work best when combined with traditional static stretching, though further research is needed to determine optimal vibration protocols.

Different forms of sleep deprivation may lead to a decline of cognitive functions in individuals. Studies in this field make a distinction between total sleep deprivation, chronic sleep restriction, and the situation of sleep disruption.
