Methods: Thirteen sprinters were recruited in this randomized, balanced-order designed study, and were asked to perform three treatments, included whole-body vibration exercise (5 sets × 30 sec, 30 Hz, ± 1.8 mm) combined with post-activation potentiation (PAP, 5 sets × 1 reps × 90%1RM) (WBV+PAP), PAP (5 sets × 1 reps × 90%1RM), and control treatment (CON). After standardized warm up, participants performed the first 100 m sprint test. After 4-min rest, participants performed the WBV+PAP and PAP treatments. 5-min after treatment, participants performed the second 100 m sprint test. Rating of perceived exertion (RPE) was recorded before and after every sprint tests. In CON, the second 100 m sprint test was conducted immediately at 4-min after the first 100 m sprint. The segmental and accumulated times of sprint test were measured by the timing gate system. Results: The split time (10－20, 80－90 and 90－100 m) in PAP was significantly faster than those in control (p < .05), and the split time (80－90 and 90－100 m) in WBV+PAP was significantly faster than those in control (p < .05). The cumulative time (0－90 and 0－100 m) in WBV+PAP and PAP treatments were significantly faster than those in control (p < .05). Compare with CON, the RPE in PAP treatment was significantly lower at before and after second 100 meters sprint test (p < .05). Conclusion: Both WBV+PAP and PAP activities could improve the 100 m sprint performance in sprinters, however, the high-intensity dynamic warm-up could further enhance the 10－20 m sprint time.
