The purpose of this research is to explore the effects of 8-week vibration training courses (of different frequencies, i.e., 30 Hz and 50 Hz) on long jump athletes' lower limb special strength, special physical fitness indicators, and balance and how these effects differ according to the vibration frequency. This study will help introduce this new training method into long jump training regimens. Overall, this effort will add diversity and innovation to current practices, improving both the training and teaching in long jump.
